How to get Airtel 250mb with #300

This trick has been around for some time now and i felt like sharing it.
With this plan you get 250mb data valid for a whole month and the goodnews there is that it works on all devices, be it java, Android, symbian,BlackBerry
and all other devices .

You may be wondering if this plan will work for you, be rest assured that this plan does not select sims and another good thing is that it does not require too much protocol to activate it .

Simply send "MBBM" without the quote to 440 use the default configuration and you are good to go, Goodluck .
