Samsung S23 Network and Data Issues

I’ve been having some major problems with the network and mobile data on my Samsung S23, whether I’m at home or at my summer house. It’s really annoying that everyone else with the same mobile carrier seems to have no issues, while I can barely make calls or get online. This definitely indicates that the problem is with the device, not the carrier. I’ve noticed that this might be a common issue with this model, but Samsung hasn’t officially recognized it. I thought a company this big would take some responsibility. I’m not just after a quick fix—I need a solid explanation and a lasting solution to a problem that I know others are facing too.
