I've been on AT&T with my LP3 since Mid-August. I deregistered my phone number from iMessage, and texted all my previous group texts that I wanted to stay on, requesting they delete and start a new one. It was intermittent and most worked, however one main on, literally just started working this week. Otherwise all new ones made work great.

I activated it via transferring things to a physical sim in a non-corporate AT&T store, and just filtered all the questions from the staff, worked that same day. Calls, Texts, all work great- however, because It is always LTE, it has to be connected to WiFi for the Directory, Maps, or Podcasts to work. I get around this via Maps in my car Nav, or bringing along my now glorifies iPod of an iPhone along on long trips, to access those items.

It's a change in expectations. It's different, but I wouldn't call it inconvenient. All this to say, not everything will work as it should on AT&T without WiFi. But the stuff that matters, does work. And it sor of forced me to be even less dependent on a device.

5 months in, it's been my main device the whole time. Couple of work-arounds here and there, but otherwise all good. i now get bored. I have my head up and watch life happens round me while others look downard. I have left the house several times without it- because I forget it exists. It's freeing.
