A:AnswerWe bought this phone for my father in law who lives in Bolivia. For his job he travels throughout Latin America on the Entel network. He has used the phone in Argentina.
A:AnswerUnknown but I bought two and one has problems holding the charge. The other is average so it is unknown if the battieries are replaced or are originals.
A:AnswerI'm not sure, but I have to charge the battery every other day. Charges very quickly with the included fast charger and seems to hold the charge very well.
