Virging and Boost are owned by Sprint, so that means their network uses CDMA technology. If the S3 is a GSM phone (i.e. take a SIM card) it will not work on their networks, however it could work on AT&T, T-Mobile or StraightTalk, since their networks use GSM technology.

This will only work on GSM carriers like AT&T or T-Mobile. If you have any further questions on this issue or would like to speak with a live agent, please call: 1-888-BESTBUY
