Updating the Preferred Roaming List (PRL) on a mobile device is necessary to maintain proper connectivity when traveling internationally.
True
False
The Preferred Roaming List (PRL) is a database residing in a wireless (especially mobile phone) device that contains information used during the system selection and acquisition process. In the United States, the PRL indicates which bands, sub bands, and service provider IDs will be scanned and in what priority order. However, while updating the PRL can improve roaming capabilities in domestic regions by connecting to new towers, international roaming often relies on separate roaming agreements and may not require a PRL update. Devices may use different technology or networks when traveling internationally, such as GSM or CDMA.
