I got a Lumia 830 right when it came out. I ordered it online. Like usual, AT&T screws everything up and somehow I lost voicemail and our bill was totally screwed up. I got voicemail back but now I've noticed that when I don't have very good service, or don't have service. Pretty much any text message that get's sent to me gets lost or something. When I had my Lumia 920, whenever I would regain service my text messages that I missed would come in at the same time. Has anybody had this problem? Is it something that AT&T also screwed up when I ordered my new phone?
