Will a GSM galaxy s6 active be compatible?
I don’t believe so. The Galaxy s6 Active is an AT&T exclusive phone. Republic needs unlocked phones to work. Sorry about that!
more details Republic has only approved North American regional factory unlock models
no carrier version has ever been approved to work on Republic
Unlocked versions of the S6 active can be found all over eBay at this time. Does that mean that this is now a viable phone? Previously, the only reason stated for it being incompatible is that it is locked.
Republic needs the North American Factory unlock versions (not just unlocked from the carriers)
for the Samsung S6 the North American Factory unlock shares the model number with the T-Mobile Version and there for one must check the build of the software
Build numbers For the Samsung Galaxy S6
Please note: The T-Mobile branded version of this phone is not compatible with our service.
There is a difference between factory unlocked and carrier unlocked. Specified factory unlocked variants are tested and supported. Carrier unlocked variants are not. To the best of my knowledge, there are no factory unlocked variants of the S6 active.
