Will Republic phone work for in-country calls in Europe if unlocked and European country sim card installed?
It’s always helpful to mention which phone you are inquiring about.
Here is some excellent information on using your device when travelling outside of the Country.
International Travel with a Republic Phone
Let us know if you have any questions.
Legacy phones [1st gen Moto X, G, E, 2nd gen Moto X, E, and 3rd gen Moto G] can’t use an local international SIM due to their custom ROM.
All 3.0 phones are unmodified and can be used on any provider willing to activate it.
I think it’s solved here.
