I live in San Diego and have been a previous owner of SEVERAL Samsung phones, the latest being the S-9+. I got the S-10 + and had SEVERAL similair issues to include roaming on my home network.
I did everything that Savededa dis to include talking to support in the Phillipines of all places. NOTHING could be done to include switiching out the SIM Card which did not work. The phone would aloow me to make and receive calls when it wanted to. I could not send text messages with or without photos unless the phone decided to some 8 hours later.
I returned the phone and re-activated my S-9+ and have had NO ISSUES with the phone. I couldn't depend on the S-10+ for calling 911 or to stay in touch with my kids. SAMSUNG has a hugh issue with this phone and it has nothing to do with this link you put up.
