I worked on these. The phone's price is subsidized into the card pricing, so they would loose money if you could do that. They had us design them that there could be no swapping (they are locked to the pay-as-you-go sims). Unlocking requires both software and hardware modifications - at least the phones we made.
- abyssknight 18y agoI can comment on this. My wife is on tmobile and my father is on ATT, both are using prepaid phones with swapped SIM cards. I know the Virgin mobile phones don't use SIMs (to my knowledge) as well as Tracphone, so those are useless.
- coryrc 18y agoIf you don't power it on with the SIM card, they usually work.
- drewcrawford 18y agoThis must be a recent development, because I made extensive use of this trick (1-2 years ago?). Specifically, the $10 walmart ATT go phones worked fine with the contract (3G) SIMs.
