AT&T prepaid sim card activation
Hi! I just received my prepaid SIM card and when I tried to activate it following the direction, it says my SIM card is active and shows the phone number that I want to transfer as well as the plan I bought. However when I tried to create an account using my number, it shows an error saying the information provided is not valid. I also tried to call 611 but my phone can't make any call with this SIM card. I'm not sure why this is happening as it should have been activated already? Thanks for any help!
