What does cell phone PRL mean?

Hello, mobile phone PRL is the abbreviation of preferred roaming list. When the operator starts a new frequency (such as 3G), the original users need to update the PRL file. When the operator signs a new roaming service provider and the user needs to roam abroad, the PRL needs to be updated.

PRL updates can only be made in China. If the user has gone abroad, PRL will not be updated. So be sure to update PRL before going abroad. Send SMS update manually: send PRL (case insensitive) to 10659 165.
