Updating at t roaming list
Is there a way to update my phone [PRL] or similar to help give it the most signal as possible in new locations? If the SIM doesn't update, try turning off the phone, remove the sim and then turn on the phone without the SIM and it should update the PRL.
The best i can expect in the Steel building and that area. Mines shows 15480 but I don't know when the last time it was updated as my phone is on 24/7/365.In fact, this whole story was borne out of a colleague's own frustration about the topic.So I talked with Apple and all four major carriers — AT&T, T-Mobile, Sprint and Verizon — to get more information.You may also get a message in i Tunes the next time you connect your device to your computer via USB.If you notice any network issues or problems using such features as voicemail, it's a good idea to check that you haven't missed a carrier settings update using the steps outlined above before contacting your provider.
