My phone (OPPO A77s) suddenly stopped getting 4g network. It is showing (E) Edge connection only. Did restart, replaced sim at T-Mobile store, reset the network settings, and other things...None on theses stepes worked.
My phone (OPPO A77s) suddenly stopped getting 4g network. it is showing (E) Edge connection only. Did restart, replaced sim at T-Mobile store, reset the network settings, and other things...none of these steps worked. It is an international phone and it was working perfect for more than a year, and it suddenly stopped working on 4g data network.
It is unlocked international phone (OPPO A77s).
The phone only supports a couple of Tmobile’s 4g bands in the 5 and 41 so it's not a great choice for using on Tmobile except in areas that support those bands..
