Airtel 4G, how to shift to 4g Airtel is sending smart SIM to new 4G users.

The 4G roll out is finally picking steam in the National Capital Region with Airtel testing its signals across many parts of the urban conglomerate. Many customers across the regions, especially those on premium plans, are getting messages asking if they want to shift to 4G.

This is how the process works:

1. You will get an SMS asking if you would like to opt for the new service. Those who don’t get the same can go to the Airtel 4G SIM swap page and request a new SIM

2. Once you request for a new SIM, Airtel will try and deliver it at your address within four hours. While not everyone is getting it within four hours, most SIMs seem to be delivered within the same day. Airtel is delivering only smart SIMs for its 4G service, so there is no need to get them cut for newer phones.

3. To change the SIM, you need to send the 20-digit number at the back of the new card to 121 prefixing SIM. When the request is accepted, select 1 to confirm.

4. Within a few minutes the service on your existing SIM will stop. Once that happens, insert the new SIM and wait for the network to show up.

5. Within a minute of so, you should get a message with the new Internet settings. The 4G service is ready to go.

For me the entire process from the first SMS (step 3) with the SIM swap request happened within 12 minutes. The SIM delivery happened the same day, but not within 4 hours as promised. And I personally know people who have waited for over a week and have not got the SIM yet.

Some users will need to upgrade their plans to avail 4G services. Over, the next couple of weeks we will tell you how the 4G connectivity is in the NCR region.
