I purchased this phone from Wireless Experts, Inc. The product was as described, new in box with all accessories, locked to AT And T and included the full one-year Apple warranty. The iPhone SE model number was A1662.I was able to activate this phone on my AT And T post paid account without a problem, just put in the AT And T sim card I was using with my unlocked iPhone 8 Plus and set up the iPhone SE. Since I haven't been under an actual contract with AT And T for years, just for the fun of it, I used the AT And T website to see if I could get the phone unlocked. However, I wasn't at all surprised to get back a message saying that they couldn't unlock this AT And T prepaid device right now since it hadn't been active for six months. This of course made sense to me, seeing as the phone was purchased at a much lower price than regular retail. But, having never purchased a prepaid phone before, I did call and speak with someone at AT And T to confirm I could use this phone on my post paid account and was told there would be no problem.I am very happy with this phone. Although I do like my 8 Plus, this phone gives me a break from the larger size of that one, and I am able to switch between the two without a problem.I wouldn't hesitate to buy this phone again from this seller.
