Text msg not delivered after cell signal restored

[Android Central Question]

Lately, I've noticed that if I am in a dead done such as a store and someone sends me a text message , my phone never received it after I leave the store and cell signal is restored. I am using Galaxy S6 on AT&T. Tried Android Messages, Textra, and Samsung Messages.

Any tips? Thanks

Ask your local AT&T store where the Device Support Center is. Take the phone there. (They're the tech people at AT&T.)
