Hello sir,

I have upgraded my airtel sim to 4g sim on 12th august 2017 at the airtel office. After upgradation my sms service are blocked.
Sms plays very important aspect in our daily routine work and my most of the banking services are linked with sms.

When i contacted airtel customer care they told me to wait 48hrs before they register any complain and if complain get registered after 48hrs it will take another 72hrs to resolve this issue.

This is very serious issue that airtel blocking sms services o[censored]ser after upgradation to 4g sim without any prior intimation.
