Horrible reception

[AC Question]

I recently switched over to T-Mobile from AT&T and upgraded from a Galaxy s5 to an s6. I keep having multiple tell me when the call me it hangs up on them. I don't even receive their call. Also, I receive texts hours later. I have full bars and everyone else in my house doesn't have a problem. Someone please help me. It's beyond annoying. Thanks!
