Hey, I have traveled to Nigeria for Christmas. I've got my sim card in a spare phone but there is no service on my phone. This means I cannot receive any one-time passwords for my banking and other essential apps.
Nor can I call the contact number on the EE website to fix this issue.
I don't want to make any calls or texts while I'm here but I want to be able to receive them when necessary.
Is there anything I can do to unlock my sim card so I can receive OTP? FYI I know this is possible because my sister, who is with me on this trip, has an EE sim card and is able to receive calls and texts from abroad.
