Current Plan ReviewCall Tariff:• Rs 299 is paid as a tariff to get free call minutes• Bill tells you the duration of all calls=351 minutes(335 minutes local + 11 minutes
night call and 5 minutes STD)• Charges(without tariff) for this plan is 30paise/min for local & night calls and
50paise/min for STD calls• So by his usage of 346 minutes for local & night calls is should pay= Rs 104 but he is
paying Rs.299• So he is paying a lot more than the actual chargeNet Tariff:• Currently he is being charged Rs 236 per 1gb data usage so he will be charged Rs 500
for his data usage which fits good with his current planSMS tariff:• He pays a tariff of Rs.50 in which he gets 288 free local messages i.e. nearly
17paise/sms• His on peak time of sending sms is in evening so for that particular time he can be
charged at 10p/sms and for rest of the time 17p/sms• Thus his tariff can be Rs.35/month for free local SMS.
Plan that suits the customer
•Airtel My Plan would be a very good option for our customer• It is a do –it –yourself
postpaid plan that will let you use your phone in the same way you want it
Plan that suits the customer(cont’d)
Select the rental that you find suitable
Select the My packs of your choice
PredictionGender-Male• The call duration were less and usually females are prone to talk more compared to male.• In fact, women talk almost three times as much as men, with the average woman chalking up 20,000
words in a day - 13,000 more than the average man.
Approximate Age-35-45• The duration of the calls is very less and thus he uses only the phone for business purposes• People contacted in day is far less than a person of much younger age will doKind of phone-• Smartphone,3G enabled• Huge data transfer and usage compared to a normal mobile phoneAny other information-• Occupation can be a businessman or an executive • Data pattern- the kb/s is not used enough in any day as compared to a student.• Thus we can predict the person only uses the data pack for not so heavy uses such as
downloading but for basic necessities like checking e-mails, social networking or business sites etc.
