Re: how can i tell if a galaxy s3 will accept a consumer cellular sim before i buy the s3 online?
It has to be SIM-unlocked. CC uses different towers in different locations. (If the seller won't guarantee that it's unlocked, look up the price of an unlocking supplier on eBay and ask the seller to deduct that amount from the price. (If the phone is currently activated on a plan, the seller can ask the carrier for the unlock code - they have to provide it. It may take a few days for them to get it, but they have to - by law.)
