Preferred Roaming List...it is a list of SIDS (System IDs) that the carrier has roaming agreements with. When your carrier updates their roaming agreements they in turn need to update your PRL. PRL is a CDMA term so you probably have Verizon or Sprint service. I know Verizon does PRL updates over the air but I'm not sure about Sprint. You probably won't notice reception differences with an updated PRL, only coverage improvements. Sometimes carriers expand service areas and that too can be impacted by an updated PRL.what does prl stand for?
How do you do it?

Hmmm I wonder if thats why my phone rebooted last night on its own. Is it an automatic download?
I want to know how the OP finds out what the PRL is fixing, or where he finds this information.
