iPhone 5 running iOS 7.1.2. Carrier "Sprint 16" and PRL 51101.
In the past I have been able to use the method of replacing carrier.prl in the sprint_lte_us carrier bundle folder, use the PRL push flag in carrier.plist, and with a few reboots I could get full time verizon 3g roaming with "prl 00001."
I am now visiting Alaska and am stuck on PRL 51101 with "extended" coverage and 1x data. I have tried every PRL I can find (11114, 11119, 53135, 00001) and I seem not to make any difference. After making the prl changes and after the last reboot I am stuck at no service. When checking phone info it will still say 51101.
I have to restore a backup of the sprint_lte_us carrier bundle folder and then things will work again after a reboot.
Any ideas? WIll the PRL update only work if there is native Sprint service around to start with?
When things are working with 51101 @ 1x speeds on "extended" I can do the ##update# and it say success.
Any help appreciated, would just like 3g data while traveling.
You are correct, but that's future talk. Based on how att is running their network here with far less density compared to tmo and Verizon .. if Sprint can run band 25+band 25 ca combo I think it could work

Where I go to my parents most of the time LTE is not even available. Evdo is a joke in terms of speed and signal strength and 1X is also just about useless.. So one of the few things should happen if the merger doesn't go through Sprint better find a way to densify their Network across-the-board where they already have service. And or co locate with Verizon which has a majority of the cell sites in the area. Or the other option would be is to actually build their own sites because as it stands with Sprint in my town they wouldn't have even a reliable evdo and 1X Network so Sprint needs to really really densify the entirety of their network here or voice over LTE will be a joke.
It's not about pushing coverage through B26. It's about densifying and making sure you have enough access points that UEs can reach.
The main problem with VoLTE will be existing devices not reaching cell towers. Sprint is notorious for having places where you can get a decent signal and usable DL speeds, but uploads fail (and this is not due to congestion). If you don't have a consistent uplink, VoLTE will fail even with QoS. I sure do hope VoLTE is an opt-in trial while we wait for the merger to close as the network today cannot sustain reliable VoLTE.
