My sim card is currently barred as I haven't swapped to the new sim. I have moved addresses a few times in the last few years and don't know where they sent the new sim. I tried to login to my online account and each time I was asked to answer to a security question that is not visible. I called the 789 number a while back and they couldn't help me. I had that number for years and use it for my business and the current situation is not helping. Would appreciate it if someone can help me.
