"Invalid Sim Card" message/ Error: ER05
I tried following the instructions here https://support.t-mobile.com/docs/DOC-33..., because I am currently using t-mobile, but it didn't seem to help me. How do I make the message go away? (I don't care about Wifi calling btw).
这是一个好问题吗?
It's an "alcatel one touch fierce 2" BTW.
