How to Activate 3G in Airtel

To activate 3G on your existing Airtel connection steps are below:

1) Check if your city has 3G available

2) Call 12134 to activate 3G or

SM 3G to 121

You will get a response saying reply with “1″ to activate 3G. Send 1 to 121. You will receive 3G profile via SMS within 4 hours. Save that and use it for the Internet applications as you do for 2G.

Make sure your mobile Network setting is set for Dual Mode( 2g/3g UMTS) not just GSM mode.

    I tried that option but after dialling 12134, option1 was not available due to technical upgradation so I spoke to executive by some option (9 I guess) and he activated it immediately.
