USA calling

[Dunner]

Got USA package but won’t let me make phone calls and I have unlimited calls and texting

Are you calling from Canada to USA?
Are you in USA and are trying to call USA/Can?

More details are needed...

Hello @Dunner 

Question, are you currently in the US now or are you trying to make calls from Canada to the US?

If you are in the US, go into your network settings and turn off automatic then choose T-Mobile then reboot.

If you're in Canada trying to call the US, try rebooting the phone. If that doesn't work, try resetting your networks then reboot.

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.

For your voice issue, 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
