I have a BT SIM only contract and as I am remote want to use it in a 4G router (just as a backup to my BT broadband) I am not able to connect to the internet from it via wifi (wired connection is fine via the 4G router). I think it might be because of it requiring a PIN from BT but not sure. Anybody able to advise or had this problem? No PIN came with the SIM.
Thanks
