CDMA means Code Division Multiple Access – Verizon, Sprint, US Cellular, and Boost Mobile are all examples of CDMA carriers. TracFone, Straight Talk, Walmart Family Mobile, and Consumer Cellular are MVNO’s that are also compatible on CDMA networks, but you will need to ask to have a specific CDMA compatible SIM card. GSM means Global System for Mobile communication – AT&T, T-Mobile, Metro PCS, and Cricket Wireless are all examples of GSM carriers. TracFone, Straight Talk, Walmart Family Mobile, and Consumer Cellular are MVNO’s that are also compatible on GSM networks, but you will need to ask to have a specific GSM compatible SIM card. MVNO means Mobile Virtual Network Operator. An MVNO cell phone carrier is typically a prepaid plan and does not have its own network but instead borrows network infrastructure from a CDMA or GSM carrier.
