increased and students remained stable. The growth rate for working people also increased, proving that the need to study TOEIC among working people in recent years has increased rapidly.

- Test the relationship between demographic variables and consumer behavior for Mobile Marketing activities
The analysis method used is the Chi-square test (χ2), with statistical hypotheses H0 and H1 and significance level α = 0.05. In case the P index (p-value) or Sig. index in SPSS has a value less than or equal to the significance level α, the hypothesis H0 is rejected and vice versa. With this testing procedure, the study can evaluate the difference in behavioral trends between demographic groups.
CHAPTER 4
RESEARCH RESULTS
During two months, 1,100 survey questionnaires were distributed to mobile phone users in the inner city of Hanoi using various methods such as direct interviews, sending via email or using questionnaires designed on the Internet. At the end of the survey, after checking and eliminating erroneous questionnaires, the study collected 858 complete questionnaires, equivalent to a rate of about 78%. In addition, the research subjects of the thesis are only people who are using mobile phones, so people who do not use mobile phones are not within the scope of the thesis, therefore, the questionnaires with the option of not using mobile phones were excluded from the scope of analysis. The number of suitable survey questionnaires included in the statistical analysis was 835.
4.1 Demographic characteristics of the sample
The structure of the survey sample is divided and statistically analyzed according to criteria such as gender, age, occupation, education level and personal income. (Detailed statistical table in Appendix 6)
- Gender structure: Of the 835 completed questionnaires, 49.8% of respondents were male, equivalent to 416 people, and 50.2% were female, equivalent to 419 people. The survey results of the study are completely consistent with the gender ratio in the population structure of Vietnam in general and Hanoi in particular (Male/Female: 49/51).
- Age structure: 36.6% of respondents are <23 years old, equivalent to 306 people. People from 23-34 years old
accounting for the highest proportion: 44.8% equivalent to 374 people, people aged 35-45 and >45 are 70 and 85 people equivalent to 8.4% and 10.2% respectively. Looking at the results of this survey, we can see that the young people - youth account for a large proportion of the total number of people participating in the survey. Meanwhile, the middle-aged people including two age groups of 35 - 45 and >45 have a low rate of participation in the survey. This is completely consistent with the reality when Mobile Marketing is identified as a Marketing service aimed at young people (people under 35 years old).
- Structure by educational level: among 835 valid responses, 541 respondents had university degrees, accounting for the highest proportion of ~ 75%, 102 had secondary school degrees, ~ 13.1%, and 93 had post-graduate degrees, ~ 11.9%.
- Occupational structure: office workers and civil servants are the group with the highest rate of participation with 39.4%, followed by students with 36.6%. Self-employed people account for 12%, retired housewives are 7.8% and other occupational groups account for 4.2%. The survey results show that the student group has the same rate as the group aged <23 at 36.6%. This shows the accuracy of the survey data. In addition, the survey results distributed by occupational criteria have a rate almost similar to the sample division rate in chapter 3. Therefore, it can be concluded that the survey data is suitable for use in analysis activities.
- Income structure: the group with income from 3 to 5 million has the highest rate with 39% of the total number of respondents. This is consistent with the income structure of Hanoi people and corresponds to the average income of the group of civil servants and office workers. Those
People with no income account for 23%, income under 3 million VND accounts for 13% and income over 5 million VND accounts for 25%.
4.2 Mobile phone usage in Hanoi inner city area
According to the survey results, most respondents said they had used the phone for more than 1 year, specifically: 68.4% used mobile phones from 4 to 10 years, 23.2% used from 1 to 3 years, 7.8% used for more than 10 years. Those who used mobile phones for less than 1 year accounted for only a very small proportion of ~ 0.6%. (Table 4.1)

The survey indexes on the time of using mobile phones of consumers in the inner city of Hanoi are very impressive for a developing country like Vietnam and also prove that Vietnamese consumers have a lot of experience using this high-tech device. Moreover, with the majority of consumers surveyed having a relatively long time of use (4-10 years), it partly proves that mobile phones have become an important and essential item in people's daily lives.
When asked about the mobile phone network they are using, 31% of respondents said they are using the network of Vietel company, 29% use the network of
of Mobifone company, 27% use Vinaphone company's network and 13% use networks of other providers such as E-VN telecom, S-fone, Beeline, Vietnammobile. (Figure 4.1).
Figure 4.1: Mobile phone network in use
Compared with the announced market share of mobile telecommunications service providers in Vietnam (Vietel: 36%, Mobifone: 29%, Vinaphone: 28%, the remaining networks: 7%), we see that the survey results do not have many differences. However, the statistics show that there is a difference in the market share of other networks because the Hanoi market is one of the two main markets of small networks, so their market share in this area will certainly be higher than that of the whole country.
According to a report by NielsenMobile (2009) [8], the number of prepaid mobile phone subscribers in Hanoi accounts for 95% of the total number of subscribers, however, the results of this survey show that the percentage of prepaid subscribers has decreased by more than 20%, only at 70.8%. On the contrary, the number of postpaid subscribers tends to increase from 5% in 2009 to 19.2%. Those who are simultaneously using both types of subscriptions account for 10%. (Table 4.2).

The above figures show the change in the psychology and consumption habits of Vietnamese consumers towards mobile telecommunications services, when the use of prepaid subscriptions and junk SIMs is replaced by the use of two types of subscriptions for different purposes and needs or switching to postpaid subscriptions to enjoy better customer care services.
In addition, the majority of respondents have an average spending level for mobile phone services from 100 to 300 thousand VND (406 ~ 48.6% of total respondents). The high spending level (> 500 thousand VND) is the spending level with the lowest number of people with only 8.4%, on the contrary, the low spending level (under 100 thousand VND) accounts for the second highest proportion among the groups of respondents with 25.4%. People with low spending levels mainly fall into the group of students and retirees/housewives - those who have little need to use or mainly use promotional SIM cards. (Table 4.3).

The statistics in Table 4.3 are similar to the percentages in the NielsenMobile survey results (2009) with 73% of mobile phone users having medium spending levels and only 13% having high spending levels.
The survey results also showed that up to 31% ~ nearly one-third of respondents said they sent more than 10 SMS messages/day, meaning that on average they sent 1 SMS message for every working hour. Those with an average SMS message volume (from 3 to 10 messages/day) accounted for 51.1% and those with a low SMS message volume (less than 3 messages/day) accounted for 17%. (Table 4.4)

Similar to sending messages, those with an average message receiving rate (from 3-10 messages/day) accounted for the highest percentage of ~ 55%, followed by those with a high number of messages (over 10 messages/day) ~ 24% and those with a low number of messages received daily (under 3 messages/day) remained at the bottom with 21%.

When comparing the data of the two result tables 4.4 and 4.5, we can see the reasonableness between the ratio of the number of messages sent and the number of messages received daily by the interview participants.
4.3 Current status of SMS advertising and Mobile Marketing
According to the interview results, in the 3 months from the time of the survey and before, 94% of respondents, equivalent to 785 people, said they received advertising messages, while only a very small percentage of 6% (only 50 people) did not receive advertising messages (Table 4.6).

The results of Table 4.6 show that consumers in the inner city of Hanoi are very familiar with advertising messages. This result is also the basis for assessing the knowledge, experience and understanding of the respondents in the interview. This is also one of the important factors determining the accuracy of the survey results.
In addition, most respondents said they had received promotional messages, but only 24% of them had ever taken the action of registering to receive promotional messages, while 76% of the remaining respondents did not register to receive promotional messages but still received promotional messages every day. This is the first sign indicating the weaknesses and shortcomings of lax management of this activity in Vietnam. (Table 4.7)

Based on the statistics table 2.12, the majority of customers using the IELTS training course are students. In 2017, the proportion of students accounted for 64.6% (equivalent to 84 students). However, in 2018 and 2019, this proportion decreased to 63.5% (equivalent to 89 students) and 62.2% (equivalent to 92 students), respectively. Although the proportion has decreased somewhat, the number of students using the course has still increased and maintained. In addition, the proportion of students registering to use the course has increased over the years, from 13.8% in 2017 to 16.2% in 2019 (an increase of 2.4%).
In summary, through the data on the subjects of the 2 training courses, it can be seen that the proportion of students and working people registering for the course is increasing. This shows that the Center is having a good relationship when cooperating with high schools and businesses through effective distribution and promotion policies. This helps to enhance the awareness and reputation of the Center to students in this group. As for the student group, this can be considered the main group registering to use the Center's 2 training courses. Although the number of students has increased significantly over the years, it can be seen that the proportion is gradually decreasing. With a competitive pressure
With the fierce competition today, with large centers, new centers opening more and more, and exam preparation classes focusing on this group, development for this group is becoming more difficult than ever, requiring great efforts to attract students from businesses.

The market that the Center focuses on mainly belongs to Thua Thien Hue province. Through the data table, we can see that Hue city accounts for the highest proportion and this is also the most important market that the center targets. In 2017, the proportion of students in Hue city reached 89.6% and decreased sharply in 2018 to 86.7% (down 4.9%). Compared to 2018, the proportion of students in 2019 decreased to 85.7% (down 1%). The reason for this decrease is the sharp increase in students in towns. Specifically, in 2018, the proportion of students in towns reached 11%, a large increase compared to 2017 at 6.1% (growth rate of 140%), while the proportion in 2019 increased insignificantly compared to 2018 at 0.3%. The increase in the proportion of students in the town since 2018 shows that the Center has had very good policies to penetrate this market to find more customers for itself. For students in the districts, the proportion over the years has fluctuated insignificantly and is very small compared to the other two regions (even the growth rate in 2018 was negative compared to 2017) because the Center only distributes at the central building at 18 Le Loi, Hue City. With such a long distance, it is also relatively difficult for students in the districts to register to use the Center's training courses.

2.3.1. Characteristics of survey sample
During the investigation, 100 survey forms were distributed and all of them were valid for analysis. Therefore, the investigation study included 100 customer samples with the following characteristics:

Gender information
The number of male and female students interviewed had a large difference with 37 male students accounting for 37% and 63 female students accounting for 63%. This sample structure ensures objectivity in the study.
Age information
The number of students is spread across 3 age groups, in which students from 18 to 25 years old account for the highest percentage at 64%. This is understandable as the majority of the age group are students with a great need for training courses, playing a big role in making decisions to choose and buy course products for use. Next are students under 18 years old accounting for 19% and the remaining are students from 25 to 40 years old accounting for 17%, these two age groups have an insignificant difference in student percentage.
Career information
The main subjects using the Center's courses focus on 3 main subjects: students, students, and professionals. In which, students account for the largest proportion with 60 students accounting for 60%. This is the group with many needs and purposes to register to study at the Center. Next are students and working people, accounting for 19% and 18% respectively, in which working people are the group that can completely control their own finances. In addition, there is another group that accounts for a relatively small proportion of 3%.
Income information
The number of research samples with income under 3 million reached the highest rate of 76% equivalent to 76 people, this is the average income level in Hue city, so the high rate is true to reality. The next highest rate is the income level from 3 to 5 million, accounting for 13% equivalent to 13 people. In addition, there are subjects with income from 5 to 10 million, accounting for 9% and over 10 million, accounting for 2%.

(Source: SPSS 20 data processing results) Most students choose to buy and use IELTS courses, accounting for 64%, the rest is TOEIC courses, accounting for 32%. It can be seen that the number of students registering to use
IELTS courses are used more because of their practicality and more skills and can be easily and flexibly used anywhere. In addition, there are also some students who register to use both courses and account for an insignificant number of only 4%.

(Source: SPSS 20 data processing results)
Based on the processing results table, we can see that 63% of students have been using the course in the past 6 months, which proves that the majority of the survey subjects are new students of the Center. Next is the group of students who have been using the course for about 6 months to 1 year, accounting for 20%, students who have been using the course for about 1 to 2 years, accounting for 14% and finally 3% of students who have been using the course for 2 years or more.
Reasons why students choose courses at the center

Chart 2.1. Reasons why students choose the Center's courses
There are many reasons for students to register for courses at the Center. Based on chart 2, we can see that there are 8 main reasons why students choose courses at the Center. In which, students can choose many reasons at the same time, the reasons with the highest percentage are "teachers, enthusiastic, friendly" and "flexible schedule" with the rates of 71% and 73% respectively in the total of 100 students. "Quality course" and "Prestigious center" were both chosen by 54% of the total number of students. Next are the reasons "Knowing the Center through the media" and "Teachers with high professional qualifications" chosen by 39% in the total of 100 students. Meanwhile, the reasons related to "price" and "promotion" had the least number of choices in the total of 100 students surveyed, respectively 28% and 32%.
* Information channel to help students know about the Center

According to statistics through the survey of the Center's students, up to 37 students out of 100 students approached the Center through friends' referrals. 35% of surveyed students chose to approach the Center through advertising on Facebook. The remaining 2 forms were less accessible to students, specifically, students who were directly called by the Center to customers were only 17 out of 100 students and approached by flyers were only 11%.

(Source: SPSS 20 data processing results)
Through table 2.12, we can see that the significance level (Sig.) of all variables is less than 0.05. This confirms that we have enough basis to reject the hypothesis H 0 , accept the hypothesis H 1 for all 4 criteria and it can be said that the general perception of students about the criteria in the product policy is different from 3. Combined with the t values of the observed variables being all greater than 0, we can conclude that customers' perception of the criteria in the product policy is greater than 3.
But it is also necessary to add, for the criterion " The Center often organizes workshops and activities for learners ": (GTTB = 3.88) Although the Center has done relatively well, perhaps to increase the general feeling of learners towards the course, the Center needs to increase the number of specialized workshops, avoid traps or test-taking tricks. From there, it will increase the general feeling of learners towards their training course.

(Source: SPSS 20 data processing results) Using One Sample T-Test, we see that with a confidence level of 95%, the test for the significance level (Sig.) of the variables is less than 0.05, which means there is enough evidence to reject the hypothesis H 0 and accept H 1. In addition, the t-value of all variables is greater than 0, which means that customers have evaluated the criteria in the Center's pricing policy.
AMES Hue International English is above neutral.
For the criterion “There are reasonable costs for supporting documents”, the average score is 3.57, which is still lower than the other 3 criteria. This shows that some customers do not completely agree with this criterion. In fact, the cost of documents and books is not related to tuition fees, students need to spend more money to buy their own study materials. Students can buy those materials by buying them at the consulting counter, bookstore or photocopying, etc. Because the study materials are self-managed by students, many students may not agree with this criterion. In order to increase customers' perception of this criterion, the Center can offer price incentives to support students in reducing the cost of documents.

- Test the relationship between demographic variables and consumer behavior for Mobile Marketing activities
The analysis method used is the Chi-square test (χ2), with statistical hypotheses H0 and H1 and significance level α = 0.05. In case the P index (p-value) or Sig. index in SPSS has a value less than or equal to the significance level α, the hypothesis H0 is rejected and vice versa. With this testing procedure, the study can evaluate the difference in behavioral trends between demographic groups.
CHAPTER 4
RESEARCH RESULTS
During two months, 1,100 survey questionnaires were distributed to mobile phone users in the inner city of Hanoi using various methods such as direct interviews, sending via email or using questionnaires designed on the Internet. At the end of the survey, after checking and eliminating erroneous questionnaires, the study collected 858 complete questionnaires, equivalent to a rate of about 78%. In addition, the research subjects of the thesis are only people who are using mobile phones, so people who do not use mobile phones are not within the scope of the thesis, therefore, the questionnaires with the option of not using mobile phones were excluded from the scope of analysis. The number of suitable survey questionnaires included in the statistical analysis was 835.
4.1 Demographic characteristics of the sample
The structure of the survey sample is divided and statistically analyzed according to criteria such as gender, age, occupation, education level and personal income. (Detailed statistical table in Appendix 6)
- Gender structure: Of the 835 completed questionnaires, 49.8% of respondents were male, equivalent to 416 people, and 50.2% were female, equivalent to 419 people. The survey results of the study are completely consistent with the gender ratio in the population structure of Vietnam in general and Hanoi in particular (Male/Female: 49/51).
- Age structure: 36.6% of respondents are <23 years old, equivalent to 306 people. People from 23-34 years old
accounting for the highest proportion: 44.8% equivalent to 374 people, people aged 35-45 and >45 are 70 and 85 people equivalent to 8.4% and 10.2% respectively. Looking at the results of this survey, we can see that the young people - youth account for a large proportion of the total number of people participating in the survey. Meanwhile, the middle-aged people including two age groups of 35 - 45 and >45 have a low rate of participation in the survey. This is completely consistent with the reality when Mobile Marketing is identified as a Marketing service aimed at young people (people under 35 years old).
- Structure by educational level: among 835 valid responses, 541 respondents had university degrees, accounting for the highest proportion of ~ 75%, 102 had secondary school degrees, ~ 13.1%, and 93 had post-graduate degrees, ~ 11.9%.
- Occupational structure: office workers and civil servants are the group with the highest rate of participation with 39.4%, followed by students with 36.6%. Self-employed people account for 12%, retired housewives are 7.8% and other occupational groups account for 4.2%. The survey results show that the student group has the same rate as the group aged <23 at 36.6%. This shows the accuracy of the survey data. In addition, the survey results distributed by occupational criteria have a rate almost similar to the sample division rate in chapter 3. Therefore, it can be concluded that the survey data is suitable for use in analysis activities.
- Income structure: the group with income from 3 to 5 million has the highest rate with 39% of the total number of respondents. This is consistent with the income structure of Hanoi people and corresponds to the average income of the group of civil servants and office workers. Those
People with no income account for 23%, income under 3 million VND accounts for 13% and income over 5 million VND accounts for 25%.
4.2 Mobile phone usage in Hanoi inner city area
According to the survey results, most respondents said they had used the phone for more than 1 year, specifically: 68.4% used mobile phones from 4 to 10 years, 23.2% used from 1 to 3 years, 7.8% used for more than 10 years. Those who used mobile phones for less than 1 year accounted for only a very small proportion of ~ 0.6%. (Table 4.1)

The survey indexes on the time of using mobile phones of consumers in the inner city of Hanoi are very impressive for a developing country like Vietnam and also prove that Vietnamese consumers have a lot of experience using this high-tech device. Moreover, with the majority of consumers surveyed having a relatively long time of use (4-10 years), it partly proves that mobile phones have become an important and essential item in peoples daily lives.
When asked about the mobile phone network they are using, 31% of respondents said they are using the network of Vietel company, 29% use the network of
of Mobifone company, 27% use Vinaphone companys network and 13% use networks of other providers such as E-VN telecom, S-fone, Beeline, Vietnammobile. (Figure 4.1).
Figure 4.1: Mobile phone network in use
Compared with the announced market share of mobile telecommunications service providers in Vietnam (Vietel: 36%, Mobifone: 29%, Vinaphone: 28%, the remaining networks: 7%), we see that the survey results do not have many differences. However, the statistics show that there is a difference in the market share of other networks because the Hanoi market is one of the two main markets of small networks, so their market share in this area will certainly be higher than that of the whole country.
According to a report by NielsenMobile (2009) [8], the number of prepaid mobile phone subscribers in Hanoi accounts for 95% of the total number of subscribers, however, the results of this survey show that the percentage of prepaid subscribers has decreased by more than 20%, only at 70.8%. On the contrary, the number of postpaid subscribers tends to increase from 5% in 2009 to 19.2%. Those who are simultaneously using both types of subscriptions account for 10%. (Table 4.2).

The above figures show the change in the psychology and consumption habits of Vietnamese consumers towards mobile telecommunications services, when the use of prepaid subscriptions and junk SIMs is replaced by the use of two types of subscriptions for different purposes and needs or switching to postpaid subscriptions to enjoy better customer care services.
In addition, the majority of respondents have an average spending level for mobile phone services from 100 to 300 thousand VND (406 ~ 48.6% of total respondents). The high spending level (> 500 thousand VND) is the spending level with the lowest number of people with only 8.4%, on the contrary, the low spending level (under 100 thousand VND) accounts for the second highest proportion among the groups of respondents with 25.4%. People with low spending levels mainly fall into the group of students and retirees/housewives - those who have little need to use or mainly use promotional SIM cards. (Table 4.3).

The statistics in Table 4.3 are similar to the percentages in the NielsenMobile survey results (2009) with 73% of mobile phone users having medium spending levels and only 13% having high spending levels.
The survey results also showed that up to 31% ~ nearly one-third of respondents said they sent more than 10 SMS messages/day, meaning that on average they sent 1 SMS message for every working hour. Those with an average SMS message volume (from 3 to 10 messages/day) accounted for 51.1% and those with a low SMS message volume (less than 3 messages/day) accounted for 17%. (Table 4.4)

When comparing the data of the two result tables 4.4 and 4.5, we can see the reasonableness between the ratio of the number of messages sent and the number of messages received daily by the interview participants.
4.3 Current status of SMS advertising and Mobile Marketing
According to the interview results, in the 3 months from the time of the survey and before, 94% of respondents, equivalent to 785 people, said they received advertising messages, while only a very small percentage of 6% (only 50 people) did not receive advertising messages (Table 4.6).

The results of Table 4.6 show that consumers in the inner city of Hanoi are very familiar with advertising messages. This result is also the basis for assessing the knowledge, experience and understanding of the respondents in the interview. This is also one of the important factors determining the accuracy of the survey results.
In addition, most respondents said they had received promotional messages, but only 24% of them had ever taken the action of registering to receive promotional messages, while 76% of the remaining respondents did not register to receive promotional messages but still received promotional messages every day. This is the first sign indicating the weaknesses and shortcomings of lax management of this activity in Vietnam. (Table 4.7)
