messages

I’m having trouble receiving any messages and or calls and I can’t send any messages or call anyone as well. I don’t know if this is an issue for just myself or for everyone else. I’ve already restarted my phone twice to see if that was the issue but no. What can I do? 

On your bill?  No.  T-Mobile does not store text messages sent and received by customers unless subpoenaed to by law enforcement.
