I want to unlock a phone, but don't know which sim card will work with the phone. I don't want to use at&t or verizon. I'm trying to find the cheapest carrier to go with. Any suggestions?
Any GSM carrier will work on your unlock LG Shine CU720. GSM cell phone carriers are A T&T and T-Mobile. These two network use sim cards and their sim cards will work on your unlock cell phone.
Verizon and Sprint does not use GSM (no sim cards) rather they both use CDMA network.
