AIRTEL AFFORDABLE PLAN

I'ts all about affordable internet plans. Before trying any of these plans, it is advisable you migrate to Airtel's Club 10. Do that by dialing *166#

You can get as much as 6GB Data for N3000 only on Airtel with validity of 90 days. The following table gives you all the plans for the Airtel Unlimited Blackberry Plans with their respective USSD Codes. Use the one that is applicable to your need. Blackberry UNLIMITED 2 IN 1 OFFER 3 months 90 days N3000 *440*016# or BBUM3 to 440 6GB.

3 days (72 hours) N200 *440*018# or BBUD3 to 440 246MB

Now, the 4GB package is actually not a straight one. But for those who have subscribed for N1500 bis previously, all u need to do is to dial *440*161#. So if you have subscribed for the 1500 bis previously then u are eligible for this 1+1 package. If it does not work for you directly, Send Deactivate to 440, Then subscribe to Airtel's N100 10mb plan by dialing *141*712*11#.
It will add to your initial data balance, then you'd be able to use it. Dial *141*712*0# to check your data balance and expiry date.
