Firstly, it's a great price for an unlocked phone that can be used with AT&T, TMobile, prepaid, and any other GSM (SIM card) service providers worldwide. I'm not going to repeat the technical specifications. It is very light, portable and has excellent battery life. You can talk for a really long time. Make sure to turn off WIFI when it's not being used. This phone is perfect for everyday use, or as a backup or a second phone. I love the FM radio.

It also makes a decent gift.

I would recommend it over any carrier branded phone. It is always cheaper in the long run to get an unsubsidized phone.
