I just got two new AT&T 4G go cameras. Neither of them are able to find the AT&T network. They keep saying “register network failed, please check your SIM card and restart”. I know the signal is strong where I am at because I have five of the cameras and they work flawlessly. I must be forgetting to do something but I don’t know what it is. I have put in the IMEI numbers as well as the ICCID numbers. Both cameras show up on my camera management page online, and both cameras show up on my phone app. But there is no connection and therefore no report. Any suggestions would be greatly appreciated. I always seem to have an insanely difficult time getting the cameras to work when I purchased them. Once they are connected however, they seem to run great. Thank you for any help in advance.
