Current Sprint PRLs

Recommended Posts

Anyone know anything about PRL 20989 -- it's what I currently have on my iPhone 5s.  I did a few searches here and on XDA and didn't turn up anything.

 

I haven't had a chance to go through the PRL list since the 5S launch. I know the 5S and 5C use different C-SIM cards instead of the standard UICC cards every other LTE device uses (albeit each slightly different for mini/nano size and whether they allow GSM or not).

 

Makes sense that something different might be required for the PRLs as well, Apple loves to make things more complicated.

And Sprint loves to make many useless series of PRLs...

Such as the 54xxx series? Since it seems to be for corporate world phones like 56xxx apparently is...

 

Anyways, looks like a new set of PRLs have been released. Sprint just pushed 54016 to me, which of course overrode the custom PRL I had been using in place of the previously issued 54015. I am curious to see if the full set of 1x 800 SIDs have now been added.

I'll let you know when someone pulls it from their device and sends it to me.  No one has done this yet though.

Just did ##UPDATE# on my iPhone 5 and now I'm on 51098.  I used to be on 51097.

My guess is we're either losing native coverage like always, or this has something to do with that uscc transaction in the Chicago area.

Just got the update on my 5, curious as to what's changed.

I'm in the Chicago burbs and just received my 5s in the mail. PRL is 20989, too

How do you do this, if I have time and can, I'll try...

If you find the QPST guide for your device on writing a PRL all you do is hit read and save. It usually saves as rl0 but it is still a PRL.

Just updated my PRL and it now says 25016. It was 25015.

The PRL on the HTC Evo is now 55016  I got it the other day, but couldn't remember if that is what it was before I updated.  :blush:

We know the PRL versions based on the devices and account types already ;)  I have the new versions thanks to autoprime and I will be checking them out.

Interesting... we have a new 800SMR channel in the scan:

 

1X: S/476 S/487 S/526

 

So, using AJ's formula in his article, "What's the frequency, Kenneth?" Interpreting your engineering screen. Part two.

 

uplink center frequency (MHz) = 806 + (0.025 × carrier channel)
downlink center frequency (MHz) = 851 + (0.025 × carrier channel)

 

476 = 817.9 downlink / 862.9 uplink

487 = 818.175 downlink / 863.175 uplink

526 = 819.15 downlink / 864.15 uplink

 

I thought maybe this is what Sprint did with the 800SMR that went missing in our area earlier this week but I still can't connect to it even though I scan see it on the spectrum analyzer.  I'll have to check to the see the exact frequency the carrier is at now though.

Honestly, I am not surprised.  My suspicions had been raised, as I have not had CDMA1X 800 for about the last week now.  If the carrier channel assignment has been shifted from SMR 476 to SMR 487, that would explain the disappearance.

 

Sprint may have determined that it needed to shift the CDMA1X 800 carrier up a few hundred kHz for out of band emissions reasons.  Who knows?  But this change should not affect the 5 MHz FDD LTE 800 carrier at all.  Even at SMR 487 with a downlink center frequency of 863.175 MHz, the upper 625 kHz of the CDMA1X carrier should extend to around 863.8 MHz.  On the downlink, that still leaves 864-869 MHz for the 5 MHz FDD carrier.

Preliminary reports:

800SMR scans now include channel 487.
CA GEOs scan an additional PCS channel
Alaska Digitel changed from native to roaming indicator shown.
Cleaned out some old unused Alltel SIDs

And that's about it so far... I'll do some additional digging later today.

Thanks for the additional info.  Probably why I haven't seen them turning up 800SMR on any new sites in over a month now here.  Weird that I still can't connect to it with this new PRL.  Will have to do some more research.  Maybe I'm not holding it right?

Still connecting to 800 SMR on 476 in Shentel area.  Using Galaxy S3 with 25016 PRL

This probably explains why I haven't seen 800mhz on my usual towers these past 2 weeks. Thanks Digiblur for the quick analysis!

For the time being, Sprint may have turned down the sync and paging channels on SMR 476, leaving only the pilot channel running.  In that case, the carrier will show up on a spectrum analyzer, but mobiles will not be able to attach to it.

I just did a PRL update on my Galaxy S4 and now have the 55016 PRL up from 55015 in Madison, WI.  Once I updated, I got a blip of 1x800SMR (as chimed by SignalCheck Pro) but then 800SMR went away and haven't had it since.  I didn't see much for this phone or PRL on that gdoc in OP.  I've got a lot of tower work around me but nothing active in my immediate area.

I have not seen 1x800 on signal check for about a week in KC.

      Given the fact that Virgin has access to Extended Coverage ever since it's Inner Circle plan still now with it's current one at least according to customer service. Shouldn't Virgin be using PRL 55070 like it was with Inner Circle or is 7080 correct? I feel like there's an issue that isn't being paid attention too. Does PRL 7080 have the necessary stuff to make the device roam on Sprints extended partners.

      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.

      Today PRL 51095 was pushed to iPhone 5 on Sprint. Anyone with a LTE world phone also get the same PRL file?
       
      Not sure what is different yet. If I knew how to extract the PRL from my phone I would gladly send the file to digiblur for analysis.
    • By serqion
      Does anyone in the area where Sprint released their LTE coverage has the PRL from the iPhone 4s? If so, how has the speed increased? If it's a lot better, please upload the PRL so I can try it out.
       
      Thanks

      Recieved new PRL 25005 today, Had to do a manual update to get it..
      What tool does one use to see the differences?

    • A great article by Jim Patterson on rcrwireless.com. Some nuggets format 2.5GHz: “Braxton, Mike and John have authorized me to do some work at risk this year in getting ourselves ready to deploy the 2.5 gigahertz spectrum as soon as the deal closes. Nobody is more impatient for this thing to close than me. I wish I was deploying 2.5 radio on the network right now, but we’ve done work at low cost in terms of securing, permitting, and authorization to deploy 2.5. So as soon as this deal closes, we’re in a position where we can start laying down 2.5 radio on the new T-Mobile network.” Enterprise:   T-Mobile inherits not only a trough of spectrum with the Sprint acquisition, but hundreds of seasoned enterprise sales executives.  As Mike Sievert recently acknowledged in his appearance at the Citi conference a month ago, T-Mobile is under-indexed in enterprise.   Sprint’s enterprise roots are significant, having commanded close to 20% of the enterprise data market as recently as 2006.  There are many sales executives who cut their teeth with fleet management solutions (Nextel and Sprint), wireless access solutions (Clearwire and Sprint) and IP MPLS (Sprint).  *Without going through all of the details it’s important to note that the Apple iPhone 7 and iPhone 8 (and their variants) have the 2.5 GHz band already installed in the GSM (T-Mobile) version, and that the CDMA (Sprint) version of these devices already has T-Mobile’s Low Band 700 MHz spectrum, a.k.a. Band 12 (and Band 66 in the case of iPhone 😎 already enabled.  The CDMA version of the iPhone SE also has Band 12 enabled. Bottom line: there is the potential for backwards compatibility within the current handsets. And the iPhone XS (and variants) and iPhone 11 (and variants) are universal devices and include T-Mobile’s 600 MHz band which will be have a big benefit for Sprint customers. https://www.rcrwireless.com/20200216/analyst-angle/the-sunday-brief-new-t-mobile-cat-5-hurricane  
    • Good.  I bought shares in Shentel (SHEN) and US Cellular (USM) a year or two ago when their stock prices went down.  Waiting for a business consolidation event that causes their value to double or more.
    • Nice.  All three of my 4G Sprint phones are ready or near ready for upgrade.  I will wait until the "attractive offers" start.
