Hello @robinho2U ,
Welcome to the community,
BT use the same as EE, so not sure why there should be any difference.
Are you in the UK? Roaming is when you are out of the country, not in the UK.
If in the UK, could you please check here to see if there is a problem where you are, you can also register and receive updates:
