Network connection in USA

[neilferguson1]

Samsung Galaxy A70 

On list as compatible VoLTE etc

Roaming on,  Volte calls SIM1 on and mobile data obviously on.

Arrived in USA and unable to connect at all.

Have no spend cap , so that not issue 

Using Scan Network Operators option phone displays 

T Mobile and Verizon ,,Neither works, message is " unable to connect try later " or " sim cannot connect to this network" 

Sky support have escalated matter but not heard from them, need it working now ..Any ideas

Is this app set to abroad:

Sky Menu App or SIM toolkit > Roaming > Make sure this is set to Abroad.

Whilst no spend cap should work, have you tried setting one?
