I live in the UK and will be holidaying in America. I have some AT&T Go sims, one micro sim (for an Iphone 4) and one ordinary sim (for a 3GS)
Currently I am confused about how far in advance of my holiday I can activate them.
Is the maximum post activation period 30 days?
In the UK the term is "top up" is it "refill" for AT&T?
Go to Solution.
You have 26 days after activation to refill or top up. Please note that the time is based on US Central Time.
Thanks for the quick and helpful reply.
AT&T GoPhone is changing its name to AT&T PREPAID. New name - same great service, network and value!
