No Service on iPhone 6 - Tried Multiple SIMs
My iPhone 6, factory locked to AT&T, refuses to connect to the network even after at least 10 DFU (or iTunes) restores (always setting up as new iPhone). I've tried multiple known-good SIM cards. Of course, I've also tried the obvious such as "Reset Network Settings", getting a new SIM from AT&T, and enabling/disabling various settings such as LTE and roaming options; all wit no avail. My iPhone is out of warranty therefore taking it to Apple isn't an option. I've already replaced the lower Lightning dock connecter assembly which has one antenna, of course. Also replaced the antenna at the far top center of the device on the back side of the motherboard. Absolutely no luck. Any suggestions?

Check in settings>general>about. Does the IMEI # show up?
