For 2 times I paid to use Public Mobile in the US and I could not connect in Connecticut and in NY

@Di18 

what phone do you have?

and can you confirm which network you tried? manual connect to both? and you changed the network mode from automatic to 4G/LTE?

[Di18]

I did everything you suggested and came back without being able to use Public Mobile service in the US for the second time

[Di18]

I did many times

Critical part to US roaming depends on T-Mobile/AT&T coverage and whether you can connect successfully onto either network.

If the phone is not connecting to T-Mobile/AT&T, change the Network Connection from Automatic to Manual and select and test both T-Mobile and AT&T and see which one you can connect.

If your issue is with data, make sure your Roaming Mobile data is enabled and you have disabled your mobile data limiter.  Also change your network mode to 4G (and don't try 5G until you can connect and works on 4G)

If your issue is with voice, make sure VoLTE is enabled on the device setting.  And if it does not work, try to change the Network to T-Mobile ONLY, and change  Preferred Network Type or Network Mode to 2G and see if the calls go through.
Also, you can download VoIP app TextNow as a workaround to make calls and text if you have Wifi or if your roaming has data component and data  is working

hi @Di18 

 try to connect manually to both AT&T and T-Mobile, leave the network with 4G or LTE and see which network works
