Sim Upgrade To 4g

You can call 121 from your mobile with Airtel services and ask for a new 4G sim. You can also go the Bharti Airtel website and submit your details to request for the sim. Once you receive the 4G sim, you have to send the 20-digit number on the back of your sim at 121, prefixing sim.
