I switched to the new PM Canada/US 50gig plan. Do I need to turn on roaming when I cross the border?

@Gordon5   Some phones automatically switch while some need to have T-Mobile or AT&T manually selected.  Some phones have tried to connect to Verizon which is not a Public Mobile roaming partner so won't work.  You might be better trying T-Mobile, in fact if your phone is non-VoLTE it will be your only option.  Make sure data roaming is turned on.  If you have any problems post back here and we can help troubleshoot.

Thx for your advice. Is it possible to do nothing and that PM will connect to AT&T as roaming is included in my plan?

Yes roaming can be on.

Do you have a VoLTE enabled phone? If possible, put your phone to 4G/LTE and connect to T-Mobile or AT&T.   

If calls don't work, put your phone to 2G and connect to T-Mobile. 

I hope this will be helpful.
