Activating a prepaid SIM card outside the US for use in the US?

It is possible to activate the SIM card but won’t be possible to select or purchase a plan. You won’t have usable service until a plan is selected and paid for.

So to clarify, we are able to receive regular US mail due to being stationed overseas with the US military. I still can't order a SIM card with a plan to be delivered to our US address here?  I really have no idea how this works exactly. I'm just trying to be as prepared as possible before we visit family so that it's easier and faster once we're in the US later this summer.  We recently had family visit us from the states and they did a similar thing with a European SIM card so they had service as soon as they landed. Is that not possible going the other direction?

Thanks!

I don’t know if ATT will ship to an APO or not. If not, you can order a SIM card from Amazon or EBay. You don’t purchase a plan when you order the SIM card. Once you activate the SIM card, you get assigned a phone number. You use that phone number to login to your prepaid account to select and purchase a plan. You can activate the SIM card online from outside the US but you can’t access your prepaid account from outside the the US to select your plan. That you can’t do until you arrive. You have 60 days to select a plan after activating the SIM card. 

Thank you!  That is very helpful. 🙂  We've lived outside the US for so long at this point that I don't know how much of this works anymore!  We may just deal with it and hit Wal-Mart when we arrive. 🙂

Thanks again!
