I know some places in Asia have cheap sim cards $1, But I am in USA. I like to do it myself instead of trust others. (1) Is there any way I can get a prepaid PHONE (say they charge $0.25 per text) to verify facebook, and buy lot of 50 sim cards and just put in phone when I want to switch number? I want to pay for 1 phone, not for 50 lines for the 50 sim cards. (2) anyone know a "multiple" sim card? You know the ones that let you hold 16 phone numbers on 1 sim card, that works in USA? (3) any phone I can get (not sim card), but phone itself has multiple numbers built in? any other way to do this?
