If you're on Sprint or Verizon, or another CDMA-based network, you might have heard the term PRL thrown around once or twice. It stands for Preferred Roaming List, and it's basically a way of telling your phone phone where to look for a signal so that you get faster, better connections. Technically, it tells your phone which frequencies to scan and in which order.
Do you need to keep it updated? Sure. Sometimes it's an option in your settings; or you can do it via a phone call. Is it something to lose sleep over? Nah. But knowing is half the battle.
