Considering upgrade to S22+ -- reception better than S20 FE 5G?

Samsung modems have been very disappointing over the past few years.  The best devices for usable signal in areas where service is a bit on the weak side, would be OnePlus devices.  I get no service in my apartment on any other devices except using OnePlus devices.  Whether it's the 7 Pro, 8T, or 9.  They all give me 2 bars of usable service where an iPhone, S9+, S20 FE 5G, and other devices have no service.  Obviously, where you are and the bands deployed locally might vary as well as any kind of potential interference.
