Why is my Huawei phone not showing preferred network type in settings

[Android Central Question]

I don't just understand what's the problem my data network shows E and nothing else.
I can't change the network, preferred network is not even in the system.

Whos your carrier, have you tried contacting them ? Is your sim card old ?

I'll leave a Link to register so you can communicate here as a guest account you can only post questions but can't reply

Welcome to Android Central! What's the exact model name/number of your phone? Are you certain it supports your carrier's bands?
