Apple assumes no responsibility with regard to the selection, performance, or use of third-party websites or products. It's pretty easy to do: When a carrier setting update is available, you'll be prompted to install it. Wed Sep 20 While this mode of operation gives operators the most control over the system selection process, it requires that PRLs be kept up-to-date to ensure that newly added roaming partners can be selected. Notice we said it connects to the correct tower and not the strongest tower. While this mode of operation is easier to maintain, because new partners can be chosen even if they are not explicitly listed in the PRL, it carries with it the danger of allowing the mobile device to become camped onto a system that will not provide it with service. Risks are inherent in the use of the Internet. If you're in an area with weak but steady signal from your carrier, the PRL will connect you to that signal rather than connect to a stronger signal on a different carrier. The idea behind the acquisition table is to optimize the acquisition time by identifying only the frequencies that should be searched, rather than searching the entire frequency spectrum. These GEOs are listed in priority order.
Not all hacking is good, kids, and when it adversely affects the network, it makes the other, good kind of hacking look bad. 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. The database consists of an Acquisition table, which lists which radio frequencies to search for in which areas, and a System table, which tells the phone which towers it is allowed to connect to, and the preferred order. Update your carrier settings on your iPhone or iPad Learn about the carrier settings updates for your iPhone or iPad. System Table — A prioritized list of systems that the device is permitted to access Preferred Systems and those that it is explicitly forbidden to access Negative Systems. It still will not select negative systems; but, if no preferred systems can be found and an unknown system is available, then it will select the unknown system.

Contact the vendor for additional information. It indicates which radio bands, sub-bands, and service provider IDs will be searched for, then allows the phone to connect to the correct tower. It's pretty easy to do: If you're in an area with weak but steady signal from your carrier, the PRL will connect you to that signal rather than connect to a stronger signal on a different carrier.

Apple assumes no responsibility with regard to the selection, performance, or use of third-party websites or products. It's built and provided by your carrier, and used when your phone is connecting to the tower. Without a correct and valid PRL, your phone won't be able to roam outside your home network, and may not be able to connect at all inside the network. When a carrier setting update is available, you'll be prompted to install it. While this mode of operation is easier to maintain, because new partners can be chosen even if they are not explicitly listed in the PRL, it carries with it the danger of allowing the mobile device to become camped onto a system that will not provide it with service.

Please help improve this section by adding citations to reliable sources. The information contained in each acquisition table entry includes an index, the network type, and associated channel blocks. Carrier settings updates let your carrier provider update carrier network and related settings to improve cellular network connectivity and performance. Each entry also provides an acquisition table index where the frequencies associated with that system are identified and a roaming indicator that dictates what type of indication should be displayed to the user when they are receiving service from that system.
