AT&T Go Phone Sim/Micro Sim Card
AT&T Prepaid Starter Guide
MicroSIM to SIM adapter
Although this MICRO SIM CARD is BRAND NEW, each one is punched out of it's card and tested (on an iPad) before it's shipped. In case you want to reuse your new smaller SIM in another phone, just keep the "back to normal" adapter for fitting it in a larger slot.
Can be used with any AT&T phone, iPhones, iPad 3g and GSM unlocked phones with 850/1900mhz.
***Can not be used to activate iPad 3G Data Plan.***
