Today's fact: I always thought phones were the same everywhere, but they're actually not. The same phone can have different versions for different countries. Things like 4G/5G bands..

Samsung and iPhones usually support most network bands, so they work well in many countries. Even if a few bands are missing, you'll usually still get good signal, calls, and mobile data.

Sony Xperia phones are a bit different, Some regional models can miss Indian 4G/5G bands or VoLTE support, which can lead to weaker signal, no 5G in some areas, slower data speeds, or even being unable to make normal calls on carriers like Jio.
