Welcome to the Community @mdrapper 😊

Just to be sure, am I correct in thinking that you've tried putting your physical SIM in the new phone, and this isn't working either?

If that's the case, I would recommend visiting one of our retail stores with a valid passport or UK driving licence, and we can make sure your SIM is activated correctly.
