@Aidenhe Do you have that sim ? Because you’ll need to receive a 2FA code to setup the account. And if your outside the UK roaming has to be enable on the account so it connects to a roaming network and the sim has to be enabled in the UK first in order to setup roaming and that’s done by texting ROAMING to 150 while within the UK.
