New Coverage for AT&T MVNOs??

This section of the forum is pretty quiet!

I live in Southern California. As of about 5 days ago, I have been able to register SIM cards from two different AT&T MVNOs [Beyond GSM and O2] onto the T-Mobile network. I have not been able to do that before. The phone works the same on either network.

Anybody here outside of Southern California that can verify or say whether the same thing is happening elsewhere?

If this is true throughout the USA that would give better coverage to users who wish to maximize their coverage. And perhaps more peace of mind to users from overseas who wish to be well covered when in the USA.

On the other hand I am not able to register on the AT&T network with a T-Mobile [prepaid] SIM or a T-Moibile MVNO [TuYo].

Well, guess what! I tried to make a phone call using T-Mobile network. I got a message that said no can do. I was able to send an SMS though. Hmmmmm.

After further experimenting I have determined that I can call to the phone that is on the T-Mobile network, BUT that phone can not call from the T-Mobile network.
