Hi, I'm a frequency visitor to the US and I have an acitive GoPhone prepaid SIM.
AT&T enables us to change plans online and this is a great service especially for global customers.
I changed my plan from $60/mon (for smartphone) to 10¢/min (for basic phone) online, but I cannot change it back to smartphone plans, although I can choose plans for basic phones.
Do someone know how to choose GoPhone rate plans for smartphones online without making an international call?
