The performance is pretty appalling, calls rarely ring through, text messages frequently arrive hours, sometimes days after they were sent to me...tried a master reset on my phone and retested to no avail and it's only a 2 month old phone to begin with...the call quality is isn't good either, more often than not theres a delay that requires a 2-3 sec pause between replies...textnow just told me there's garbage on my phone, I know, because textfree is still on it...
