How and Why You Should Update Your Phone's PRL... and Whats a PRL
If your noticing that your phone is getting a weak signal, whether your at home, a friends house or travelling to a new area one thing that can improve your connection strength is updating your devices PRL. What is a PRL? PRL stands for Preferred Roaming List; in short it is a list that allows your phone to roam off towers from other networks (ie. Sprint roaming on Verizon's network). This list is constantly changing as carriers change agreements regularly so its good to update this list.
On Android devices you can simply update or check for updates via settings. From the home screen press MENU>SETTINGS>SYSTEM UPDATES>UPDATE PRL
With Sprint and Verizon making so many changes to their networks and expanding their respective 4G coverage, they will be constantly making changes to agreements to optimize their 3G networks adjusting which towers cover specific areas and adding new towers to support all the new data hungry smart phones they've been selling like hotcakes. Updating your PRL at least once a month may really help with your call reception.
