Android 6.0 and up (Marshmallow) disabled access to the "SMS Services Center" Setup option. After a trip abroad, I wasn't able to send SMS messages. I spent weeks trying different approaches until I stumbled upon the 4G LTE Switch app, it has an SMS Services Center update option and I managed to solve my issue in a heartbeat.
