San Francisco - SFO Airport: buying T-mobile SIM card?

I will be transiting through SFO tomorrow and would like to purchase a pre-paid T-mobile SIM card to use during my one week stay in PSP.

Is there a T-mobile store or Kiosk, or any other store, airside where I can purchase the SIM card?

Thanks!

post-security in T3. But I don't think they sell sim cards. I don't think anywhere in SFO sells sim cards.

Don't know where the OP is staying but there is a T Mobile shop very close to Powell Street BART (1 block up Powell) which certainly sells their SIMs.

That's quite a distance from Palm Springs, CA (PSP) where he said he was staying.

He was asking if there was some place to buy one while he was at SFO.

Transiting through the airport.

Exactly. The Powell street BART station isn't "airside" which was the original request.

San Bruno (Tanforan shopping center, which is right next to the BART station) would be the best option for BART, but it's still not airside...

There is a Wal Mart in Palm Springs near the airport. You can buy T-Mobile prepaid phones there. If the SIM card only kit is not in stock, then you can buy the cheapest phone kit which should be $20 or less.

There is also a Target in a nearby town that should also have T-Mobile prepaid phones.

Thanks everyone.

I ended up grabbing a prepaid sim card from a t-mobile store in Palm Springs.
