I have a Samsung S22 Ultra and today I decided to set Samsung Messages as my default messaging app over Google Messages, because I like how I can change the chat background. I noticed that I can't send chats despite making sure RCS is enabled. I already restarted my device multiple times and did network settings reset but it still wouldn't work. I also called Samsung customer service but all they could advise is to restart the device. Called Globe customer service as well and they gave troubleshooting steps which didn't work either. They mentioned that RCS system is not compatible with every carrier’s network in every region which should not be the reason why it's acting up now because I was able to make it work days after getting my device from them. When I tried switching back to Google Messages, chats would work with no issues but with Samsung Messages app, it just wouldn't do it. Anyone else experiencing the same problem?
