It is unlocked so you can use whatever service you would like to use, but the phone does require a sim vary to begin to use any phone or texting abilities. The phone is affordable still with the occasional coupon attached.

The screen comes with a screen protector pre-applied. Face recognition is impeccable and that goes for the fingerprint reader (which is seamless) the battery life is amazing!

Los parlantes del alta voz funciona muy mal, casi no se escucha. I dislike the fact that the battery is draining too fast. It's very disappointing that it is marketed as unlocked and even lists sprint/t-mobile as carriers.
