Hey @ranjuraghu AT&T shut down their 2G & 3G networks. From 1st July, T-Mobile will be switching their 3G network off in the USA, resulting in some customers experiencing service issues when trying to make calls or use data. You can find more information on this here

You can perform a manual search to switch between T-Mobile and AT&T (Settings >Cellular Data>Select Network). Remember, T-Mobile for Data and calls and, if you have a 4G handset, AT&T for data only.
