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 first is to contact Sprint Customer Service and get your account approved for an update and then dial *2 and follow the instructions.If you have an Android device, you can also check your PRL by tapping Home With Verizon prepping its LTE launch and Sprint lighting up new WIMAX markets, both carriers are spending a lot of time and resources ensuring their current 3G networks are optimized.If you have a CDMA device like those found on Sprint and Verizon, you may need to update your Preferred Roaming List (PRL).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.The same thing is done today with certain CDMA Android phones, and usually ends up with the same result -- a letter from your carrier telling you it's been nice having you as a customer, but it's time to part ways.Not all hacking is good, kids, and when it adversely affects the network, it makes the other, good kind of hacking look bad.If you do not have an LTE device or the updates are failing while you're connected to Wi-Fi, then you'll need to perform these updates with Wi-Fi disabled and data enabled.
It's pretty easy to do: Android phones also have an option to update the PRL in most CDMA phones, you'll find that in the settings pages.
This information can include your phone number, or be related to the roaming network, the sign in credentials that are needed for you to access the internet, and more.
Hands-free activation, profile and PRL updates are the most common forms of an over-the-air update, and all of these updates are initiated from your phone with either a restart or by selecting the appropriate option in the settings menu.
A Hands-Free Activation encompasses both a Profile and a PRL update, as well as a Firmware check on most phones.
Any phone that’s newly purchased from Ting will attempt to complete a Hands-Free Activation the first time you boot it up, as well as on each subsequent restart until the activation has completed. Some newer LTE devices can perform these updates over Wi-Fi.
