But we have no Idea How to do that

Here i am putting the tricks for that situation...

just follow my steps:

3G ACTIVATION FOR AIRTEL:

type a message START 3G and send on 121.just after a while you will get a sms that your 3G activation accomplished.

 3G ACTIVATION FOR BSNL:

3G ACTIVATION FOR RELIANCE:

3G ACTIVATION FOR VODAFONE:

3G ACTIVATION FOR IDEA:

3G ACTIVATION FOR TATA DOCOMO:

To convert Docomo 2G sim into 3G , Type ACT 3G and send it to 53333
