4g

My 4g has stopped working and dont know what to do to get it back

Have you tried to enable them disable airplane mode on your device? This basically disconnects then reconnects to the network.

Also what device do you have? I can try and guide you to see if 4G is active in settings

Clean your sim card and reboot the phone @JW03 

Also check your post code for mast issues
