Hi @peegee100459 Has it always been like that or just recently?
Doublecheck 4G is enabled on your phone and try manual roam. See here for instructions
If that doesn't work, turn your phone off, remove your sim altogether and wait a couple of seconds and put back in and switch it on again to see if it fixes it.
