have a multi part question, first what is the most current Iphone5 PRL, and does this vary by market. Do i need to manually update the PRL or will sprint auto push it through a carrier update like the one i got when i purchased the phone.

Last we road trip frequently from New Jersey to NW Indiana and New Jersey to Orlando area FLA. ive seen that certain markets iphones have different PRLs letting them utilize 800smr 1x and other NV items that have been lit up in their areas. If im travelling down 95 will my phone be able to use these features not lit up in my area or will i have to update the prl,,or will it update once it realizes its in a different market. PHEWWW!!!

Sorry for all the questions new to iphone from android and love the future with NV.

If im in the wrong topic or there is a better one to post this in please let me know

Thanks

The PRL is the same across the country, the only variation is by device. The current PRL for the iPhone 5 is 51095. The only difference by market is actually written into the PRL, and in basic terms your phone will recognize what geographic zone you're in (Chicago for example) then apply the roaming rules for that geographic zone that are written into the PRL. To continue the Chicago example, since 800 MHz SMR and LTE are both available in that geographic zone, the iPhone will search out 1900 LTE, then 1900 EVDO, then 1900 1x, then 800 SMR, then roaming partners like VZW - in that priority order (in some phones the PRL has 800 SMR as same priority as PCS, but for some reason Sprint has dropped the priority level of SMR on the iPhone - that hopefully will change in a future PRL).

 

All Sprint iPhone 5's will have the same PRL across the country (unless you're jailbroken and manually change it which is a whole other topic & thread). That is my basic understanding of how a PRL works for different geographic zones.

I randomly tried to update my PRL and it fails. Sprint wants iPhone users to stay put lol.

 

I'm not sure why this is, but on the iPhone 5 I've only been able to get the ##UPDATE# (update PRL) function to work when I'm in a wifi network.

 

EDIT: I stand corrected, I just did it OTA. However, I've noticed I get the "update failed" message much more frequently than when I was on my 4s.

I manually did the latest update a week ago. I did notice that I had to reboot my iPhone 5 before it took effect.

      Definite usage quirks in hunting down these sites with a rainbow sim in a s24 ultra. Fell into a hole yesterday so sent off to T-Mobile purgatory. Try my various techniques. No Dish. Get within binocular range of former Sprint colocation and can see Dish equipment. Try to manually set network and everybody but no Dish is listed.  Airplane mode, restart, turn on and off sim, still no Dish. Pull upto 200ft from site straight on with antenna.  Still no Dish. Get to manual network hunting again on phone, power off phone for two minutes. Finally see Dish in manual network selection and choose it. Great signal as expected. I still think the 15 minute rule might work but lack patience. (With Sprint years ago, while roaming on AT&T, the phone would check for Sprint about every fifteen minutes. So at highway speed you could get to about the third Sprint site before roaming would end). Using both cellmapper and signalcheck.net maps to hunt down these sites. Cellmapper response is almost immediate these days (was taking weeks many months ago).  Their idea of where a site can be is often many miles apart. Of course not the same dataset. Also different ideas as how to label a site, but sector details can match with enough data (mimo makes this hard with its many sectors). Dish was using county spacing in a flat suburban area, but is now denser in a hilly richer suburban area.  Likely density of customers makes no difference as a poorer urban area with likely more Dish customers still has country spacing of sites.

      Mike if you need more Dish data, I have been hunting down sites in western Columbus.  So far just n70 and n71 reporting although I CA all three.

      Good catch! I meant 115932/119932. Edited my original post I've noticed the same thing lately and have just assumed that they're skipping it now because they're finally able to deploy mmWave small cells.
