Have you tried:
Reset your Network Settings. Tap Settings > General > Reset > Reset Network Settings. This also resets Wi-Fi networks and passwords, cellular settings, and VPN and APN settings that you've used before. If you have another device, see if you can connect your carrier's network with it in that location.
