I have a ZTE Majestic Pro LTE MODEL Z799VL. I used it on the Straight Talk network. Hardware version: Z799VLHWV1.0. bASEBAND VERSION: Z799VLB01. The Frequency band says: Tri-Mode (CDMA/DO800/1900mhz LTE 700mhz, 1700/2100mhz, 1900 mhz).
I assume this means it has a SIM for CDMA.
I want to use it in Germany and France. I think this means I need to unlock it and then purchase a SIM card for GIS.
Am I correct?
Will the phone I have still work if I switch from a CDMA card to a GIS?
