I was on 1xxxx so I did the *22899 last night and now the PRL is 52642... drove to work on the phone and did not have one issue. Drove home from work and not once did google music cutout this time... seems to have helped a bit.. still switching from 3g to 4g.

Not much you can do about this guys... It's a known issue that the Nexus is having issues with connectivity. Getting a new one won't do a damn thing.
[Samsung Galaxy Nexus] EyeOfTruth:
I have heard mix things of using *22899 I have heard it can fry your sim card.

From what I was told by the rep, it won't out right disable the card, but jack something up where it will impede your signal. I have replaced two SIMs. The first one was flaky, but the second one went completely to crap after performing a *22899. Meaning, I had 2-3bars and went to no signal to one bar unless standing outside in a field.

Bottom line, perform at your own risk. Verizon's statement is that it will damage your sim.
[Samsung Galaxy Nexus] zeppelinmad4:
*22899 is only used for activation on 3G. I do not believe that it will fry your sim card but it will not help it at all. On a 4G phone, the sim card is autonatically reactivated after every boot.
[Samsung Galaxy Nexus] treoo0_1:
Rule of Thumb:

If running a 4.0.2 rom (i.e. Stock), don't flash these radios.

If using a 4.0.3 ROM, flash and enjoy the improvement.

That's my experience, and that of a writer on ZDnet. Simple.
[Samsung Galaxy Nexus] AcE XBOX:
The only issue I had was the phone did not have a signal after it updated. All I had to do was a battery pull and it's been working fine every since.

---------- Post added at 08:42 PM ---------- Previous post was at 08:39 PM ----------

It must be a back up way to activate because I have seen plenty of 4g phones dialing *22899 before. I seen the Thunderbolt, Charge, Bionic, Nexus, Breakout, and the RAZR dialing out *22899 when the network went down and new sim activation's were failing because they were in the queue in the switch to be activated.
[Samsung Galaxy Nexus] txyaloo:
Absolutely not true. As I posted above, I had a .10 device right out of the box with data drop issues. It was dropping every 1-2 minutes in a great signal area. The Verizon store replaced the SIM 4 times and it still had problems. Signal would go from mid 90s to 120. Every time it hit 120, all data was lost, and signal bars went to a gray triangle. Also, when viewing status under settings, often when the signal dropped, the phone info like phone number, IMEI, PRL, etc would change to unknown.

Replaced the phone with a brand new one from store inventory, activated a new SIM, and have been problem free since. This definitely can be a hardware problem.
[Samsung Galaxy Nexus] LexusBrian400:
Its really strange.. I'm on the Radio Hybrid... had the 1xxxx PRL, did *22899 and my signal went from -104 to -95 and an updated PRL of 52642. Odd huh? Or maybe it isn't... either way, I enjoy the strength bump :)

According to speedtest, my avg download speed jumped up 6mbs. Was getting consistent 13-14 down, am now getting 19-20 down.
[Samsung Galaxy Nexus] kangxi:
I think PRLs beginning with 56 are for CDMA phones. PRLs beginning with 15 are for LTE phones.
[Samsung Galaxy Nexus] LexusBrian400:
Umm... What? Not sure about you.. But my nexus has both CDMA and Lte.

:)
[Samsung Galaxy Nexus] ATnTdude:
LTE devices, like UMTS and GSM before them, don't use PRL's at all. That's what the SIM is for. CDMA devices use PRL's.

Being that the Nexus LTE is both, I'd imagine it's either keeping things separate (SIM controls LTE, PRL controls CDMA) or the SIM handles both LTE and CDMA towers.
[Samsung Galaxy Nexus] kangxi:
Not sure about you... I thought one could inference that by "CDMA phones" I would be referring to phones that only have the capability to connect via CDMA. We all know 4G LTE connects to both.
[Samsung Galaxy Nexus] kangxi:
I understand what you are saying, but what I am saying is that phones such as Bionic and other 4G phones are having PRLs starting with 15. Older 3G only phones are the ones currently rocking 56.

So basically, Verizon has a system set up and our phones shouldn't be on the 56 PRL. I've read a lot of reports that people were getting the 56 PRL because they don't live in a 4G area or never had it turned on. Thus the phone never connects to the 4G tower to get the correct PRL. Manually trying to force the 56 PRL is probably resulting in something that shouldn't happen.

I've also read reports of people who had the 56 PRL and then it changed back to 15, more than likely after connecting to 4G again.
[Samsung Galaxy Nexus] EyeOfTruth:
"Galaxy Nexus on its first day of release, December 15, 2011. We have also confirmed that one day prior to the phones release, December 14, 2011, Samsung released a new software update, version i515.10, for the Galaxy Nexus handset."

"The expectation was then set that software release 515.10 would be made available to his handset by mid quarter 2012."

This is a direct quote from the BBB complain that I filed. So not sure how but even verizon exec office is calling it a software update. That looks like it has been pushed to some phones but held back overall
[Samsung Galaxy Nexus] luckylui:
The sim card is for the LTE. The PRL is for signal strength to the 3G radio thus being the GSM/CDMA name 4GLTE/3G. When I was with sprint there was a wimax radio only way to update the wimax was through a img. Vzw same way. But sprint I need to update the PRL all the time. PRL control your everyday signal strength with out a good prl we have no good signal..

To get good signal strength you need a good radio for both 4G and 3G. Also good PRL for signal strength. Thats why some ove us have like one or two bars of signal cause the PRL blows. If only vzw made it easy to swap PRL like sprint did. Too bad not many ## codes work cause AOSP dont utilize the EPST.apk which brings out the hidden ## codes. That is why I loved me sprint and a htc phones, they were notorious for this type of stuff:)

[Samsung Galaxy Nexus] TEK112:
Alright guys and gals. I just got off the phone with tier 2 technical support from Verizon and have a bunch of news to share. There is a reason why*228 is not recommended for updating your phone. That is for updating the PRL of 3G phones only. That galaxy nexus should be reporting a PRL of 15098. All of you out there who have a PRL of 52642 actually have a PRL that is provisioned for 3G phones.

Unfortunately, there is no way to go back to the old correct PRL that you should be on. You can try and call Verizon wireless to have them push a PRL to your phone. However, most likely you will need to go to the store and pick up a new SIM.

I also confirmed that the date has changed for the OTA release from Samsung. The last date was set for mid-January. The new date indicates late February. Take it for what you will of course, but I am hopeful and optimistic. Then again, since I'm out of warranty what else can I do?

While I was on the phone with technical support I inquired about the new revision 10 hardware that is floating around. The representative indicated that she had no records of a revision 10 for the galaxy nexus. However, she was only able to see what was provisioned specifically for my phone. She did a search of their internal forum and discovered a revision 10 version floating around and a customer that posted information of his and his wife's phone one on revision 10, and one revision 09. The phones were side-by-side and pulling down different signal strengths. They were completely stock devices.

So, apparently there are not enough phones out there with revision 10 that Verizon is aware of. Or, at least there are not enough revision 10 customers calling Verizon for technical support to be aware of. Sadly, I was able to determine if it truly was a hardware revision or a software revision as some claim. Common sense would dictate that it is a hardware revision due to the way it is labeled.

Well, only time will tell.

[Samsung Galaxy Nexus] adrynalyne:
Im on 52642. My concern regarding what the tech said is that shouldn't a 3G PRL look to be written elsewhere besides the sim? Being that 3g devices don't use sims to store PRLs.
[Samsung Galaxy Nexus] threepio:
Anyone running this with gummynex 0.7.0 and the franco kernels? should i run into any probs?
[Samsung Galaxy Nexus] TMFGO45:
I have the 5xxxx PRL.......what's the problem? Who can actually sit there and tell me they are having an issue with that PRL? I'm having no problems with 4g, or 3g....no dropped calls, no problems at all really. And if the PRL deals with 3g, why is my SIM being discussed at all? The SIM handles things with 4g, and why would a company design anything in a way that the end user can just **** up by dialing a number?

Makes zero sense.

[Samsung Galaxy Nexus] TEK112:
I'm glad you have a device that works fine for you. However, the good majority of us are experiencing issues which is why we are here. I can't tell you why you are not having issues, but then again, I can't tell you why kernels work for some and boot loop others. Or some drop their phone from trucks without a scratch and some drop from knee high on carpet and shatter the display. All I can do is pass on what I know, what I have been told by Verizon and have experienced. I witnessed *228 cripple my SIM.

The PRL does not deal with just 3G, PRL is the preferred roaming list. It dictates to your device how you connect. I would assume (just an educated guess) that having a PRL provisioned for 3G will not update LTE towers upon reboot, like it should. It will only update 3G towers. Also, if your SIM has nothing to do with 3G, why can't you hop on a mobile network without it? Because it is all related.

The company has done a decent job to block it. Most people can't straight up dial it. The majority of people who have done this had to save it as a contact to bypass a fail safe. However, there are still a few out there that could update using *228, but not many from what I have read.

---------- Post added at 08:54 PM ---------- Previous post was at 08:48 PM ----------

There was an easy way to test that. I turned off my phone, pulled the battery and removed the SIM. I booted up and the PRL (among other things) was unknown. So, we can guess one of two things occurred. One, it writes to the SIM, or two, it really does update upon every reboot and save locally to the device, but is volatile and it removed/reconfirmed every reboot. Perhaps that would explain why so many devices with custom ROMs are saying activating in progress every week or so. I noticed mine doing this on CodeName Android.
[Samsung Galaxy Nexus] adrynalyne:
Well I don't see that activation issue but I talked to a Verizon friend. He spent some time with tech support for me. According to them, its not overwriting the 4g prl. So it must be stored to the device but is being ignored. I'm going to try a full hard reset later and see.
[Samsung Galaxy Nexus] kangxi:
As I said earlier, I gathered that 56 PRLs were for CDMA only devices while 15 PRLs were for LTE. Thanks for the confirmation.
[Samsung Galaxy Nexus] tsk138:
Hardware 10 here with PRL 65253 after calling 288.

Haven't been able to test signal strength this last weekend due to 3G outages in Texas.

Definitely getting faster speedtests on 10 than I did on 9 in Houston where 4G signal is much better than in where I live in DFW area.

I'll do some side by side tests when I return home later this week with my wife's 09 stock.
[Samsung Galaxy Nexus] krazie1:
Are you going to get a New SIM card or a New Phone? If you get a new sim can you tell us if it changed your PRL.

When you do a full reset can you tell us if your PRL was put back to 1xxxx. I really dont want to be on PRL 5xxxx if it was provisioned.
[Samsung Galaxy Nexus] AcE XBOX:
I have a hardware 10 galaxy nexus and it works absolutely fine with prl 5xxxx. I have noticed less data drops on my drive to work.
[Samsung Galaxy Nexus] ATnTdude:
PRL doesn't control "strength", nor does the SIM. They only control what towers your phone will connect to. If a tower isn't in your PRL your phone won't connect and thus get poor reception because your device is connecting to the best tower it can "see". PRL's are a holdout from the really old days of cellular when you had a single home cell, and going anywhere else, even on your own carrier, was considered roaming. Therefore, you can have a situation where your phone can't see the CDMA tower across the street, so it gets 1 bar because it's using one 3 miles away.

GSM (by which I mean networks that use GSM SIM's, which includes LTE) doesn't use PRL. In fact, a GSM device can and will connect to any tower that's more than -130db of signal reaching your antenna. Many, including some GSM Android devices (including AOSP ROMs), can even let you manually select the network you want to use at any given time. To keep people from automatically roaming unnecessarily, each carrier has its own unique MNC, Verizon's LTE network MNC is 311-480. AT&T uses 310-410 for everything today, I believe. The SIM will prioritize the MNC's it will connect to. A Verizon SIM will always try to connect to a tower broadcasting 311480 first. If, and only if, it cannot get a good connection on 311480, will it look for compatible networks. The MNC list tells the phone, if there is two compatible roaming carriers, whether to try to connect to TelCo A or TelCo B first. If they have and MNC list like the one below, your phone will connect to B, since it can't see a Verizon or C.

Verizon

TelCo C

TelCo B

TelCo A

Therefore, a PRL is going to be ignored by the LTE radio. It's just not something the SIM or LTE network can use. Now, the point of my question, is that since Verizon has added a lot of equipment which integrates the old CDMA infrastructure with the new GSM/LTE systems, have they implemented some kind of equivalent to MNC for their CDMA towers (the SIM controls all tower selection), or do they default to PRLs when on CDMA (SIM for LTE and PRL for CDMA). My inclination is for the latter, as my phone automatically upgraded itself to the 5xxxx PRL when I couldn't make a call a few weeks ago.

Full resets don't overwrite the EFS partition, which is where the PRL is stored. At least, that's where it is on the Nexus S. I haven't messed around wit a GN enough to dig that deep. I believe Odin can erase the EFS, but I honestly wouldn't mess with it.
[Samsung Galaxy Nexus] TEK112:
This is a contradiction of what I was told by tier two. There are in fact two PRLs.

The PRL for 4G/LTE/GSM is updated automatically upon reboot and the latest is 15098.

CDMA/eHRPH/1xrtt requires a manual PRL update through *228 and the latest is 52642.

People who forced *228 force changed their PRL to CDMA. From what I gathered, it seems that having a CDMA provisioned PRL won't kill your 4G, but it will prevent it from updating as new towers become available, because the PRL is identified as CDMA and will not download the database for 4G towers.

They indicated the PRL won't be ignored by the SIM, because without a PRL it does not have a list of the preferred networks to connect to. I understand the theory of what you are saying, but is there any way to get real proof? All I can do is report what I have heard from two tier two Verizon technical reps.
[Samsung Galaxy Nexus] adrynalyne:
The prl is stored on the sim card. I did many tests last night to confirm it.
[Samsung Galaxy Nexus] adrynalyne:
After spending a few hours with this last night, I can confirm this. I can also confirm that the PRL is on the sim, not on the phone like a previous Verizon tech said. I did a complete image flash, and it stuck. Put in my wife's sim, and the correct PRL was back. So I am off to get one today because I AM waiting for LTE to be put on a particular tower and I want my phone to find it as soon as its live.

Edit: I can also confirm that Verizon has the ability to push PRLs to overwrite the 3g PRL as well, as they did it for a friend of mine (Verizon manager). Sadly, I got a silly tier 2 tech that felt that it wasn't possible, and that enabling data roaming is all I need to fix any 4G drops. I was going to ask what carrier I would roam off of for LTE, but I decided it would be easier to just get a sim.
[Samsung Galaxy Nexus] zeppelinmad4:
When I first got my phone, it was not activated. So, being the former owner of a Motorola Droid for two years, the only thing I could think to do was call *22899 not knowing 4G had anything to do with a sim card.

If what you were told was correct, what would be the way to fix this? Walk into Verizon and ask for a new sim card?
[Samsung Galaxy Nexus] TEK112:
You could call Verizon from a different line and ask them to perform a PRL push to your device - this requires tier two technical support. However, they are very superstitious. Once you say you performed a *228 on a 4G phone they will most likely tell you to go to a Verizon store and get a new SIM. It is free so don't worry about that. They will swap you out, but the pain in the ass is reverting to stock before you bring it in. You can't let them see that you are rooted or unlocked.
[Samsung Galaxy Nexus] zeppelinmad4:
Hahaha alright. I was planning on switching to CDA anyways so I'll just use odin first.

Same here. Complete image stock flash to 4.0.1 got me down to #8 hardware. 4.0.2 got me #9 hardware. The whole time i was doing this my prl was fine. Im on 5xxxx. I will call verizon to push my PRL back to 1xxxx and see if coverage is there compared to the 5xxxx...

Careful with that. If they mark it down in big reds system that you are rooted, you may get hassled or denied for hardware/software related warranty issues. I have seen this happen to people and it is almost impossible to have them reverse it.

You will notice that they watch the phone when they reboot it to see if your are unlocked, too. The guy that swapped my SIM rebooted me twice. I asked him if everything was OK and he replied that he was just looking.
[Samsung Galaxy Nexus] krazie1:
So did they give you a different sim? And has anyone been able to get a new sim that changes the PRL back to 1xxxx.

Same here. I literally copied my entire sdcard contents to a folder on the desktop. With MTP, it took a little under 4 days... Then I locked, unrooted and flashed the stock firmware. Then, I downloaded a couple of programs as not to arise suspicion. They get real curious when they get back a clean device. I know that they can't prove anything, but less questions equals faster repair time. Anyway, when they were done with it I went home, unlocked and rooted, flashed clockwork. Copied everything back over, this time it took about a fortnight and then i restored my backup and was good to go. All kidding aside, it took about two hours to go from stock to restoring my fully customized device. All I had to do was update my apps that hadn't been updated in about 4 days.

[Samsung Galaxy Nexus] ATnTdude:
Are you saying there's two lists on the SIM? That's going to take up a lot of space. Most SIM's can't even hold 100 MNC's (think about that, less than 100 six digit codes). Whether it's one or two, it's a GSM MNC List for the 4G. Depending on the implementation, though, it might be semantics. If VZ stopped using different GEO areas in the system table, then it will be functionally identical to a MNC list.

Cool. That's a much better solution, as flashing newbs won't overwrite it by accident.
[Samsung Galaxy Nexus] adrynalyne:
LOL...well...

I backed up my contents last night. Reflashed, relocked, and copied them back with the intention of getting a sim today. Got the sim, and unlocked...without backing up the contents again at my current location. So I am no better off than stock unlocked right now until i get home.

Gained one bar (sorry I forgot to check db readings before flashing), but my Speedtest results went down a bit on download, and substantially on upload. I'm most curious to see if the LTE connect time has been reduced. I'll know tomorrow when I commute in and out of service areas on the subway. Currently it takes more than 1 minute for LTE data to come up when I hit above ground. This stinks because this is the only send/receive e-mail point during my commute, and by the time 4G comes up, we're headed back underground :-(

Download that and extract it, radios are inside. You can push whatever you like via fastboot. Or someone can make an update.zip I suppose but if you rooted the nexus, you've got fastboot installed anyway.
