You may start by power cycling your phone (turn it off, remove battery and SIM and then turn it on again) if this does not work, try this, settings, wireless & networks, mobile network, Use only 2G networks, tap to remove checkmark.

Make sure is not on airplane mode.

If this does not solve the issue, I guess you have to call Tech support for troubleshooting but most likely it is a defective sim and needs to be changed
