Hi,
I've been enjoying this offer from Airtel for a while now so, I thought it would be nice if you knew about it.
Airtel's 2+1 offer entails you buying an internet bundle and getting double the value.

For example, if you buy the daily 10MB plan for N100, you'll get 20MB instead.
Sounds cool, huh?.... If you're an Airtel subscriber, it's very easy to participate in this special offer. All you've got to do is dial: *141*1*1*5# to get a list of all the available plans. Listed below are the short codes to some of the available plans:
