Can not send or receive calls from US, calls drop

[GEG]

Hi 

My plan is not working I am in NY and can't make any calls or receive calls. I am on Canada/US plans.

Please help.

Is data and SMS working? Sometimes there are issues in AT&T 5G, so I turn 5G off and don't have any issues. Some phones will also try to connect to Verizon, but they aren't a roaming partner.

@GEG  Have you tried both AT&T and T-Mobile?  Which one were you connected to when it worked?  Are you still in the same place you were when it worked before?   Did you check the VoLTE list for your phone?

This just happened. I have been using my phone in the US for the past month. I am on LTE and restarted my phone again but didn't help.

@GEG   If your phone is not on the list of VoLTE enabled phones for PM roaming, try connecting to T-Mobile's 2G network.

@GEG 

make sure you have a volte enabled cellphone. Make sure you're connecting to either AT&T ot T-Mobile.
