So I have been able to reproduce this issue a few times now:
After being at home for lengthy time(measure in more than a few hours) using my ATT Microcell site and using WiFi as well, once I leave home, the OP3 refuses to get data from normal ATT towers. Cell signal is fine, but no H or LTE. Even cycling airplane mode doesn't fix it and I need to reboot to get LTE back.
My Nexus 6P, Samsung S7, no issues.
I tested a bit at home with this and turned off the microcell site and wifi after a short time using the microcell(less than an hour), no issue getting LTE from ATT towers. It seems its the length of time is a factor.
Strange issue indeed.
