INTRODUCTION
This survey was conducted so as to analyze the behavior of students with regards to their
preferences in cellular companies and cellular connections. Instead of understanding a general
students’ behavior, we tended to divide the student category into two different genders and
studied their behavior. Almost all the information has been divided so as to understand the
preferences of both the male and female genders. Information such as the genders’
preferences of cellular network, their reason for using cell phone, their average monthly usage
etc. have been presented through graphs and charts.

Sample size: The sample size is 50 students which are further divided into 24 females and 26
males. The ratio (48%:52%) is not due to any gender biasness but rather due to the
completeness of questionnaire forms (a total of 70 questionnaires were collected).

Sampling method: The survey was conducted within SZABIST (Shaheed Zulfiqar Ali Bhutto
Institute of Science & Technology) but within SZABIST, a random sampling was done focusing
mainly, however, on the students.

Limitations: The most effective limitations that we faced were time and financial constraints.
These forced us to limit our survey on 50 observations and did not allow us to carry out a larger
scale survey which would have resulted in more accurate analysis.

AGE GROUP ANALYSIS:
The total number of observations taken during the survey was seventy (70), out of which the
fifty (50) most clear and complete questionnaires were picked out to be used in the analysis.

MATHEMATICAL CALCULATIONS OF MEAN & MODE:

The mean age was almost 21 years [(19*21+21*19+23*6+25*0+27*4)/50] while the mode class
was the 18-20 age group and this is clearly visible on the bar chart (i.e. the highest bar).

PREFERRD NETWORK ANALYSIS:
The table below shows the frequently used cellular network connection by an individual, it does
not involve the number of connections used by individual’s family. According to our survey,
many of the people (who filled the questionnaire) had more than one connection. Out of those
connections one that was frequently used was counted in the statistics.

Mode: Ufone i.e. on a general level, Ufone was preferred by the highest number (15) of
students (30% of the observations). However, both Telenor and Warid also shared almost 48%
of the preferred connections in our observations.

The above graph is used to indicate that most of the people rate their connection between
good and very good. Only a few people rate their connection as being fair or even as excellent.
None of our observations included a rating of “poor” even though our questionnaire had that
option. This clearly shows the ease with which people can change their networks (also thanks to
porting!) as an unsatisfactory performance by the network provider results in the user to
change their network. After all why keep a network you are satisfied with when you can easily
(without any charges) port your connection to another network.

When we divided the preferred connections with regards to gender, it was interesting to note
that while Ufone and Warid had the most males preferring these networks while the female
majority preferred Telenor. This could be one of the reasons why the current Telenor marketing
strategy seems to be focused on attracting the male customers.

When analyzing the reasons for their loyalty to the networks, it was interesting to note that the
highest number of males were loyal to their networks because they provided the best service
while the female majority were loyal because their networks represented a good name, thus,
the female majority being brand conscious, while the male majority focusing more on the
service provided. Also, a good number of people being loyal because of their networks being
relatively cheap, shows the economic considerations (i.e. the opportunity cost) of the students.

The above graph analyses the ratio of male and female using either the pre paid or the post
paid connections. A clear majority of both male and female use the pre paid connections. Only
a few use the post paid connections, among them, males being in majority. This shows that the
post paid connections are mostly not feasible for the students as most networks provide cheap
packages mostly to pre paid customers. Also, relying mostly on their pocket moneys, students
would find it difficult to afford the post paid connections. The few connections used would
mostly be belonging to students who might be managing their businesses or jobs along with
their university education. The number of Male post paid consumers being higher than the
Female post paid consumers could be representing the local culture where business
management is male dominant.

Our sample was mainly focused on students and the above graph is the best representation for
that. The majority of the people (both male and female) have money usage between PKR 100
and PKR 1000, almost the average affordability of a student. However, females tend to be
spending more than males. This is shown by the greater (or equal) red bar (as compared to the
blue bar) for money usage exceeding PKR 500. A good number of students also spend more that
PKR 1000 monthly and this represents the increasing usage of cell phones as a means of
communication.

The most common method of payment was found to be using the scratch cards. These cards
have been made easily accessible by the network providing companies, providing the scratch
cards at almost all shops even at the “khokha” (pan shop). However, recent promotion of easy
load also seems to have been successful as it allows the users to load any amount of money
(rather than just the amounts in which the scratch cards are available). The payment methods
are almost similarly preferred by both males and females, the number of males using bank e-
credits being higher because greater number of males use post paid connections.

The number of GPRS users seems to be almost equal to the non-users. And the case is same for
both the genders. As much data is not available regarding the number of GPRS users in
preceding years, much can not be commented on this available information. However, recent
packages introduced by the cellular network providing companies, regarding GPRS, have made
GPRS more affordable now. Though GPRS faces tough competition form Wi-Lan which is
becoming widely available in most universities.

The recent rivalry amongst the network providers have led them to continuously introducing
new and new packages. However, our survey told us that except for the SMS packages, the
other promotional packages are not so famous with the users (specially the students). Though
some of them were using some of these packages, the number was very few. This could be due
to the strict restriction that go along with these packages (e.g. time limits etc.).

We wanted to analyze as to what is the reason for the students for using the cell phones. The
answers weren’t very different from the male and the female side. The biggest majority of both
of them use cell phones because they consider it to be a necessity in today’s fast revolving
world. However, some of them were honest enough to state that they actually used cell phones
for other reasons as well rather than using the clichéd statement of necessity to justify their cell
usage. Some of them agreed that they loved talking on the phone while some honestly stated
that they didn’t have any reason for using it!

We also included the cell phone make in our questionnaire in order to find the most famous cell
phone make prevalent in the students. The answer was quite obvious and expected. Nokia,
being most famous in Pakistan, was also the most famous/common in SZABIST. Although other
brands are also found here but not in huge numbers.

Keeping the city’s law and order situation into consideration, it was not surprising that majority
of the male students tended to keep a low priced cell ranging from PKR 2000 to PKR 5000.
Although some cell lovers or those who haven’t had the “experience” yet still carry highly
priced cells, and the majority of them being females. One of the reasons for this probably being
that females are far less subject to snatching cases than males.
