Is the Samsung signal extender not compatible with my iPhone SE?

Is the Samsung 3G signal extender not compatible with my iPhone SE? My husband's 4S connects, but my new phone will not. If not I assume that the SE doesn't use a 3G signal. Is this correct? We live in a variable coverage area and it sure would be nice if my phone could use this device!

I'm not sure on the signal extender but the iPhone SE supports Wi-Fi calling. If you have a router at home you can setup Wi-Fi calling. The good news is the call will auto flip to Wi-Fi calling if the cellular signal is not good. When I go into a big super market in the South (Publix) my iPhone always flips over to Wi-Fi calling which is nice.
