As a previous owner of a ZTE phone, (two of them) I can tell you they are junk.
Warranty was useless, replacement was a pain, and I could not be happier with my new Iphone 5.
The ZTE was a daily reboot phone, especially if it wen to sleep for longer than an hour, you had to pop the battery and restart the phone to make it work.
Complete junk to be avoided at all cost.
