Airtel — emergency calls only airtel

Address:

560030

In recent times i found that airtel is having the worst service. I am residing in bangalore and on a project. But now the sim shows emergency calls only. I have done what ever i could. Same thing happens to my brother phone this deewali ultimately he had to replace the sim. So what you guys what should i spent the time on my project or should i run in search of yours airtel centers. I want that to be done quickly, as i usually travel here by uber and ola, i don't have wifi. Please quickly guide me.
