Can I remove my SIM card from my MOTO X (First Gen.),and install into an Apple Iphone? Will it work just like my Moto X?
NO this will not work
the SIM in the Legacy Phones (Moto X1, X2, E1, E2, E1, G3) are link to the phone and must stay with it.
Republic does not support iPhones (only North American Factory unlock models listed in the supported phones page
the Legacy phones are CDMA and switching phones by SIM swapping is a GSM Feature.
Than you very much for your help!!
