I’m hoping to find a cellphone friend who can help me understand why my U.S. Cellular Samsung Galaxy S5 does suspicious stuff other phones don’t do (and the other way around, my phone doesn’t do things other S5s do), and why I can’t just buy another one used and use it instead. It has to be a “U.S. Cellular” one. Obviously there is something I don’t understand. What is it?

There are lots of phones like that. For example the Samsung Galaxy S4 had different versions as well, weather it was a Verizon locked phone or other carrier or from a different country. What the “locked” means is that the phone is locked to that carrier. This means you have to use that carrier that phone is locked to in order to service it. If the phone is Verizon locked, you can only service it with Verizon. If the phone is “unlocked” this means that you can use any carrier. It is not locked to any specific one carrier and you can service it with Verizon, Sprint, AT&T, etc. Hope this helps.
