No network service in India even after international travel Add on

There is no help. Prepaid does not roam in India or anywhere else in Asia. The international travel add-on only works in select countries in Europe and the Caribbean. Sorry to say but you wasted your money on the add-on.

Yes looks like I did waste money. Is there a way I can remove the add on since there is no availability?

You will have to contact AT&T about a credit for your add-on when you return. There is

That number is for postpaid.  And it won't do the original poster any good.   They do not have service on their AT&T phone, they will not have service on their AT&T phone in India. They cannot even use Wi-Fi calling in India.
