Question
A user dialed *228 to get their brand-new phone to connect to the cellular carrier. What would this do to resolve the issue?a.GPSb.PRLc.PINd.BT
Solution
The user dialed *228 to get their brand-new phone to connect to the cellular carrier. This would update the Preferred Roaming List (PRL) on their phone. The PRL is a database residing in a wireless (primarily CDMA) device, such as a cellphone, that contains information used during the system selection and acquisition process. In the case of R-UIM-based CDMA devices, the PRL resides on the R-UIM. The PRL indicates which bands, sub bands and service provider identifiers will be scanned and in what priority order. Without a PRL, the device may not be able to roam, i.e. obtain service outside of the home area. There may be cases where missing or corrupt PRL can lead to a customer not having service at all. So the answer is b. PRL.
