Thank you for the response, I did that, but I find myself where I have to take one of the gophone plans.
Here is the situation, I have an iphone 5 (ATT) and I got a new 3G sim card, now I need to activate the sim card (phone) and purchase a prepaid card (pay as you go)..
I get online, enter the sim card number, emi phone serial number, enter personal information, then I find I am in the monthly plan.
What I want an activated sim card, then I use a prepaid card. Thank you
