Summary: These don't work with any U.S. carrier!!! I learned this the hard way, should have returned it asap!! I never even used it!! I got 60 bucks for it that's how worthless it is here in the States.
Summary: Disappointed, not so much with the phone, but with the seller more than anything. I bought a refurbished M4, that turned off 3 times in 3 months taking me to bootloader screen. This 3rd time, phone ended up being "bricked" which means it gets stuck on one screen that cannot be unlocked.
Summary: I refuse to fabricate my review this device is terrible. Why would US Wireless send this product to a consumer? I sent pictures to U.S. Wireless to support my claim and demonstrate to (Fyi- feb 18th -25 2015) them how bad device is.
Summary: Good used phone that I bought that is unlocked to send overseas to a family member that is in dire need of a good phone. Little nicked up but good enough for the price I paid and screen is in good condition.
