How to update PRL on Android phone?

dthomas

I was told that when I travel, I may “need to update the PRL to get a good connection” on my Sprint phone (a Samsung Galaxy S3). Two questions: What exactly is PRL and how do I update it?

How To: Update your preferred roaming list (PRL) on your CDMA device
http://www.androidcentral.com/how-update-your-prl-your-cdma-device

"The PRL is a list that allows your phone to roam off of towers that are not part of your native network, such as a sprint phone connecting to a former Alltel tower if none of its own are available. Because roaming agreements are constantly changing and new towers are added all the time, it's important to keep this list up to date.

For most CDMA carriers (including Verizon), you can update your PRL by dialing *228 and selecting the appropriate option. For example, on a Verizon phone you dial *228 and then select option 2 and listen to the horrible programming music while your phone downloads the latest PRL."

The PRL is the Preferred Roaming List for CDMA phones like Sprint or Verizon. It basically tells your device the information it needs to contact to cell towers in your location and improve your coverage. Since the towers’ frequencies aren’t all the same, you will need a new PRL for the different frequencies. Usually the phone will update the PRL for you, but if you are travelling a lot you might want to update it manually from time to time in an attempt to get better coverage. Under Settings>System Updates there is an an option to update the PRL manually on my phone. That’s on an LG running 4.4.2, but I don’t have another device nearby to check to see if that is universal with Android or a carrier/OEM added setting. With Sprint, you can also update the PRL by manually dialing ##873283#

Just dial *228 and select #5 and it updates PRL automatically to the latest one.
