Is Samsung S7 edge model SM-G935UZSA compatible with republic wireless?
Yes, I’m sure it is.
Is there an XAA at the end of that SM-G935UZSA. SM-G935UZSAXAA would be Samsung’s full manufacturer’s SKU. If so, it would indeed be compatible with Republic’s blended WiFi/cell service.
You’ll need a BYOP SIM, which may be acquired from Republic here or Amazon here.
