hi @Siguang 

what phone do you have? and you confirmed on My Account that it is showing the addon you purchased? Showing it US addon ?  And which network your phone currently connected to? 

Try both T-Mobile and AT&T, and try using 4G, people for it easier to connect with 4G or LTE

@Siguang  Which US roaming add-on did you get, there are several, either voice, text and data, just text and data, or data only?

@Siguang 

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

If the phone is not connecting to T-Mobile/AT&T/Verizon, 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
