Well Tier 1 tech support is clueless. Have to try Tier 2...

Go to the highest level of tech support.

After reading some threads here in regards to PRL versions and the differences between each version on different devices, I took the time to find the listing of all current Sprint PRLs.   This include

I'll send you guys the bill for the deliverable soon....    This doesn't include the 800 scan order changes as my app doesn't analyze that granular as it would be a report 5 miles long every time.

My M8 seems to keep switching between 55019 and 51101. I finally installed a ROM that allows manual PRL updates and installed my hacked version of 55019 that puts my Airave at a higher priority than the local tower. We'll see what happens when I install the WiFi calling update.

The M8 should not be receiving 55019 at all, it is not the correct PRL for a tri-band LTE device. The network for some reason is sending you the incorrect PRL at some times. Do you switch back and forth between phones at all? If not, I'd suggest calling into care and having them file a ticket for an incorrect PRL being sent to your device. This is handled on a network scale, and the system may be getting confused by something, others may be having the same issues.

Yeah, I was switching back and forth between phones. Is the 51xxx series the correct one?

My nexus 5 has been on that series of prl for as long as I can remember having it. What should be loaded on it?

I am also on the Nexus 5 and I have had 55019 for a while. No problems at all here with tri-band. I connect to all 3 LTE with no problem at all. So why am I not supposed to be on 55019?

Yes, the 51xxx series is the correct series for all tri-band LTE devices.

The Nexus 5 was recently updated to tri-band LTE, so either series technically would have worked the same on it, the network may have been sending 55xxx series to N5 devices by default. Now however, it should be getting 51xxx series.

 

The 51xxx series is intended for devices capable of SV-LTE, since the N5 is not capable of maintaining separate 3G and LTE connections it shouldn't be getting this series. It should instead be getting the 51xxx series.

 

However, it is a fairly well-known fact that Sprint uses more PRL series than are really necessary. The differences between the 51xxx and 55xxx series are minimal, and likely wouldn't show any differences on most devices other than perhaps a slightly slower connection when switching between various technologies. I am not sure, but one series may prioritize the LTE band scanning differently, this may be the way they are utilizing them at the moment. Keep in mind that the LTE band scanning is only for initially making an LTE connection, once you are on LTE, the network controls what band you connect to, regardless of what the PRL states. It can force you to Band 26 even if you have a strong Band 41 or 25 connection. It's setup this way so the network can move users around as needed to load balance and attempt to put people where they'll get the best connection in the grand scheme of things. Digiblur can probably give a bit more definite information in this regard as he's the resident PRL expert.

Hmm, my G3 is on PRL 55019. I just tried a PRL update, but it stayed put. Might be making a call into Sprint tomorrow, then.

I do know that not all phones use the same number PRL. Example, Samsung and LG I believe are using 55019. HTC  uses a different PRL number, as the iphones. I don't have my EVO active any more, but I think it could be 51019 by now.

It also makes a difference if the device is a world phone on the PRL set. Previous generations of PRLs were needed because some devices have LTE and some don't, as well as some have 800 EMSR, some don't.

Has the latest PRL "upgrade" put Verizon roamimg on the bottom rung? My phone seems to now want to hang onto a -116dBm PCS signal, something I can't even really use; it used to switch at about -105. .Utilizing the SMR frequencies doesn't appear to be on the horizon anytime soon with me being in an IBEZ area. .I'm not a happy camper at the moment. :(

Verizon roaming priority varies by Region.  It is the lowest priority in most regions for Sprint.  You may have been in one of the ones where it wasn't the lowest, but now it is, like most of the rest of the country.

Just to clarify: my GS4T is receiving 54019, but it should be receiving 52101. I leave for Spain on Thursday and just want to make sure my GSM services won't be messed up.

I don't think PRLs affect your GSM/UMTS coverage one way or another, IIRC they are purely a creature of CDMA networks.

      Dish Network/Boost Mobile cell/5G buildout thread

      By JossMan · Posted

      Your referring to the $25.00 a month Infinite Unlimited plan?  I don't see any other plans on there even cheaper than that on their website.  I was looking at the Motorola 2023 Edge fwiw as well for $10.00 a month.

      T-Mobile to acquire UScellular

      By iansltx · Posted

      A heavy n41 overlay as an acquisition condition would be a win for customers, and eventually a win for T-Mobile as that might be enough to preclude VZW/AT&T adding C-Band for FWA due to spreading the market too thinly (which means T-Mobile would just have local WISPs/wireline ISPs as competition). USCC spacing (which is likely for contiguous 700 MHz LTE coverage in rural areas) isn't going to be enough for contiguous n41 anyway, and I doubt they'll densify enough to get there.

      Boost Infinite with a rainbow SIM (you can get it SIM-only) is the cheapest way, at $25/mo, to my knowledge; the cheaper Boost Mobile plans don't run on Dish native. Check Phonescoop for n70 support on a given phone; the Moto G 5G from last year may be the cheapest unlocked phone with n70 though data speeds aren't as good as something with an X70 or better modem.

      Official Tmobile-Sprint merger discussion thread

      By iansltx · Posted

      Continuing the USCC discussion, if T-Mobile does a full equipment swap at all of USCC's sites, which they probably will for vendor consistency, and if they include 2.5 on all of those sites, which they probably will as they definitely have economies of scale on the base stations, that'll represent a massive capacity increase in those areas over what USCC had, and maybe a coverage increase since n71 will get deployed everywhere and B71 will get deployed any time T-Mobile has at least 25x25, and maybe where they have 20x20. Assuming this deal goes through (I'm betting it does), I figure I'll see contiguous coverage in the area of southern IL where I was attempting to roam on USCC the last time I was there, though it might be late next year before that switchover happens.

      Forgot to post this, but a few weeks ago I got to visit these small cells myself! They're spread around Grant park and the surrounding areas, but unfortunately none of the mmwave cells made it outside of the parks along the lake into the rest of downtown. I did spot some n41 small cells around downtown, but they seemed to be older deployments limited to 100mhz and performed poorly.
