I noticed that I can no longer roam on my Sprint GS3. I used to be able to, back when I was using the rooted stock ROM, but now I just get no signal in places where I should have roaming coverage. I know this because my brother's GS3 will be roaming in an area where I'm showing no coverage.
I tried using the LI3, LG8, LG2, and LG9 radios. Have also tried several different ROMs, including AOKP, FreeGS3, and JellyBomb. I also had manually-loaded PRL of 11115, and then tried updating, which gave me 24006.
I also tried all the different tricks I'm aware of -- toggling airplane mode to see if it will choose a new network. And I've checked to make sure that roaming is allowed and isn't set to "Sprint only."
At this point, I'm thinking of going back to stock to see if that works. I'm not sure what to expect with that, though.
Has anybody experienced anything like this?
As far as I know, you arent able to roam on 3g. If you put the corporate prl on your phone, you can then roam on other carriers.
Oops, I should clarify. I can't roam at ALL... meaning no voice, no 1X data, nothing. It shows the "No signal" icon.
Make sure you have roamimg enabled in mobile network settings

Yes, I suffered the same thing yesterday. Until roam control is fixed I suggest looking at loading of Verizon prl in this situation. It is easy enough on this phone to do it and then switch to a sprint prl when you get back to your home area.
Also check Network settings, are you on "Automatic" or "Sprint"?
I had to toggle data and voice on and off until it gave me are you sure you want to roam message after that it started working.(In roam settings)

I'm using the Samsung Epic and i just bought roam control...when i press roam only it goes into roam signal but there is no 3g or 1x or any data...did i do something wrong? how do i get data to work? Thanks
go to settings from the home screen and make sure you have data roaming turned on... but if I'm not mistaken, you will only ever data roam on 1x (talking from experience, not any known document or anything)

Data roaming is on... any other possible solution?
I have used this app before without a hitch. I couldn't get data to work until I picked "roam" for the data roam guard.

You may have already done this, but ensure your data network is ACTIVATED (hold down the power button and instead of selecting power off, select data network). If it is already activated, i.e. you get a 3G signal when you get a Sprint signal, then try deactivating it and reactivating it.
Btw, you are not using a 3G toggle widget of any sort are you? The ones that actually work only work about 50% of the time (buggy), so I don't use them anymore.
If all else fails, try rebooting, wait for a Sprint 3G symbol then switch to Roam.
I thought I remember from somewhere that our roaming is onto the verizon network. And that in the sprint/ verizon agreement, that sprint customers who roam on verizon are restricted to 1x.
I think this is part of why with sprints ec05, it won't show 1x, just 3g no matter what.
I'm running ACS recovery/kernel + root; and it was also true with Zedo v2.
I cannot get any data while roaming. I have installed and run roam control. I have tried all possible options under Settings/Wireless and Networks/Mobile Data and Roaming.
Anyone else?

Problem was fixed - see post#6

Where do you live?
no seriously
The ET4G, like previous samsung phones cannot roam on the PCS band, so if whoever your roaming on is only throwing voice over the cellular band and data over PCS then you got no data.....
No one seems to care about this bug and I don't get why not.

I'm going to have to go somewhere and roam now...(I purchased Roam Control a year ago for my Moment, but I don't want to root my ET until there is an unroot method)
I ALWAYS had data while roaming with my Samsung Moment. Granted, sometimes it was slow as molasses, but I always had it!
I'm actually seriously considering turning this phone back in... With Sprint's crappy network, once you get inside a building, often the only signal you can get is a roaming cellular signal... which makes the GSII a hair more than useless.

I had this happen. I had to go under Wireless and Network then to Roaming. Uncheck all settings in Roaming guard and Roaming settings. Reboot phone then go back and check everthing under Roaming settings again. I think I had to enable the data block under roaming guard. Anyway - it finally told me I was roaming and asked for permission to connect to data. Also using Roam Control.

Anyone know how to pull the PRL out of the Galaxy Nexus? I tried the *#*#8778#*#* that worked with the NS4G & QPST, but no dice. It would be nice to be able to use something like the 11115 PRL that allowed 3g roaming on older/other phones. I tend to get stuck in areas that have zero Sprint coverage for work a lot of times.
EDIT: *#*#3424#*#* Will put you in the right menu, I'm still working on figuring out how to get QPST to recognize the device though.
EDIT #2: From what I've been reading, the Galaxy Nexus will not work with QPST because it is not Qualcomm compliant...need to find VIA/Spirent PST to be able to do this? Anyone have any input regarding this?
I found a way to change the PRL. I'm not 100% sure that it actually changed the PRL and not just the number that shows in the menu though. The idea came from this thread: http://forum.xda-developers.com/showthread.php?t=1639839
So using Better Cut I followed the first step he outlined, JUST THE ONE ABOUT THE PRL THOUGH. Phone went through and did its reboot came back up.
At first it showed unknown as the PRL, MIN & My Phone Number. I went into *#*#yourmsl#*#* checked under edit and my info was correct, checked under *#*#3282#*#* and my username was correct in the data profile. Went back into about phone and everything had repopulated correctly.
Now where I am sitting its still showing me as connected to a 1xrtt network, but that very well could be because I'm in the middle of WY at the moment. I should be going into SLC tomorrow and I will try to force it to roam while I am there and see what happens.
Seems the post has been edited and no longer has instructions.
1.Download Better Cut (Google it)
2.Install on your phone however you see fit. I just downloaded the apk to my phone and installed from there.
3.Copy your chosen PRL to the root of your SD card and rename to Test (so instead of 11115.prl, it will show up as Test.prl)
4.Create a shortcut using Better Cut, go "Activity", "PRL Write"
5. Go back to where the shortcut is and click it. The phone will reboot and shortly after the PRL should show up in the "About Phone" section of your settings menu.
My friend just got a sprint nexus and he needs to force roam on it. His palm pre had this tweak working.
I've been using corporate PRL's on every phone I've had with Sprint and up until this phone, it has been very easy to do. From what I've read none of the traditional methods work because this phone does not use a Qualcomm chipset for the radio, it is using a VIA chipset. I will report back tomorrow if this actually changed the PRL or if it just changed the displayed numbers. It's hard to say in WY whether or not 3g service is actually available and from what I can tell I am rather far from the tower I am connected to.

The PRL should auto adjust as soon as you change regions. If its not changing and you're experiencing bad reception....etc...contact Sprint cause chances are you aren't alone.
Sent from my Galaxy Nexus using XDA
Actually none of the phone's I have used with Sprint in the past few years have changed as I moved around the country. The point in all of this is not about bad reception really, just that when roaming certain PRL's you will get 3g roaming as opposed to the regular 1x.

PRL's CAN be region specific. However, some networks (Sprint included) Only have 2 or 3 different PRL's (Virgin mobile's...etc..) So whatever PRL you have now should be fine unless Sprint lights up new CDMA networks or adds more spectrum. If you have an old PRL (dunno what revision it is, I'm on VZW) update it with ##873283#. Any connection issues you're having likely aren't the PRL and are probably more related to carrier issues or the notorious Galaxy Nexus Data Drops that almost every version of the phone has had.
Edit: You could always try the Sprint Partners PRL's...dunno if it will work though.
Sent from my Galaxy Nexus using XDA
Smokeey, I don't doubt that they can be region specific. But again, the only point in me doing this is for times when I am actually roaming due to the places I go for work. Ex: I have been in Wyoming for 5 weeks now, Sprint has Zero coverage here. So again it isn't about connection issues. It's about EVDO vs 1xRtt while roaming. The only time I use Roam Control or similar functions are to test the ability to get 3g while roaming.
Aside from that, I do not think this is the best way to go about changing the PRL manually on this phone, but for now it will do.
So .... with the 11115 PRL I was only getting 1x in WY, should have been 3g. Today I got into Salt Lake where there is Sprint coverage and I was still roaming, with the phone and Roam Control set to Automatic. I restored a backup of the stock ROM, refreshed profile, updated PRL and was back on Sprint 3g. Then went back and forced the manual update of the PRL back to 11115, tried switching to roam only mode and the phone stayed connected to Sprints network. By the time I got back into WY and was roaming again, it did properly switch to a roaming partners system and I still had 3g coverage. So it seems that everytime you write the PRL with Better Cut, you could get a different result. FOR ME this is fine, as long as it works when I am actually roaming.
I'm sure down the road a VIA compatible PST and associated drivers will turn up so that this can be done in a similar fashion to the way it was accomplished with QPST on other phones. But for now I am content.
I've linked to your post in my thread for how to update PRL manually. Your post was first.. so it's only right
and for completeness... here is my thread detailing how to use VIA tools the same way we used to use Qualcomm tools. I've linked back to you in the second post which details PRL writing. It looks like even with VIA chipsets.. we aren't so locked out after all.

PRL write not listed in any cut or better cut
I can't find "PRL write" in either Any Cut under activities or Better Cut(v3.3) under all activities. I have Test.prl in /sdcard/. I'm running a vzw gnex on CM9.1. I've tried changing it's name to TEST.prl. I've tried several different prl files.
Anyone one have any advice.

I have used this method, but through apex launcher, Also tried it using Sprint Diagnostics options, guess trying bettercut wont hurt.

Any hints on what could cause this?

Hello, this is my first post on this forum and I THINK I am placing it in the right section. If it is incorrect, I apologize!
I have looked around and I found this thread here that contained some great information. I tried all of the PRLs and I could only get 3G roaming on one of them - the 01337-mod PRL. I was using roam control with the Sprint Corporate Accounts, however I was still only getting 1x. I managed to get 3G when using the 01337-mod PRL, however I do not wish to be on Verizon all the time. I have looked around but none of the PRLs I have tried work for me with roam control. I am running the Monthly Snapshot of CM10.1. Is there a way for me to get 3G roaming with roam control?
Thanks for the assistance!
From what I have gathered it is because Roam Control turns off the 1900 mhz band leaving only the 850 mhz, cellular band. Therefore no 3G. Here is a link to a post that discusses it: http://forum.xda-developers.com/showpost.php?p=32090794&postcount=76
I use Roam Control while at work, but only for voice not data. If you periodically need 3G data, I would suggest the PRL write method to flash a modded VZW PRL for only when needed, then go back to Sprint 56006.

Hmm, that is interesting. And quite disappointing! Thank you for the heads up. And what PRL write method are you suggesting? Via dialing ##3282# is not supported on CM10.1. The only method I know how to flash PRLs on CM10.1 and other AOSP ROMs is through DFS, and a computer is required for this and it is inconvenient. I managed to get 3G Roaming for a couple minutes when on PRL 16006 I went to Roam Control, chose "Roam Only" and then rebooted my phone. I had Mobile Data on and WiFi off, and it instantly connected to Verizon's 3G. I got about 50kB/s download. However, when I went back to "Roam Control" and chose "Home Only" I connected to Sprint's 3G. I then tried to reconnect to Verizon by choosing "Roam Only" and I could only manage to get 1x.

Since I got my GS3, I have only been on a TW Rom, specifically Odex Blue by Strong Steve, so I don't know anything about CM10 on a GS3. But needing a computer to change the PRL would be a hassle.
After you rebooted, are you sure about the 3G on Verizon? You can verify by going into Roam Control and verify network status.
I ask because, If I am selected to Roam Only and reboot, I go back to Sprint.

Yes, I am positive it was on Verizon because I did check. "View network status" under Roam Control and it stated my roaming status = true and my network carrier = Verizon wireless great Lakes. I was getting decent speeds but it's unstable and if it switches to 1x, a reboot is required to get back onto 3G

Yeah, I've posted in the official Dirty Unicorns thread about this issue, didn't find a fix. It was reported before I did by someone else here.
So here's the issue: I go into Settings>Wireless & Network>More...>Mobile networks> and check all the boxes (data enabled, data roaming, n'tl data roaming). Then, in System select, the default tick box is "Home only", meaning the phone won't roam. So I tick Auto: Domestic & Int'l, so when Sprint service sucks (which happens a lot where I'm at), and I think I'm good to go. See screenshot here.
But then, I hit back to go back to using my phone to do whatever: listen to music, play RUA2, whatever. If I go back into the same settings menu, the tick box for System select has reverted back to Home only. No roaming. I try this again, no dice.
tl;dr something is wrong with the settings, I can't roam.
What I've done so far: I've tried this on FL24, FI27, and EL29. I've cleared cache and dalvik, tried fixing permissions, clean flashing multiple times, and nothing worked. Then, I've flashed Slim Bean or ReVolt, and boom, the settings work, and I can roam as usual. Whaaaaaat? So yeah. I went back to DU (7-20), because it's my favorite JB ROM. I tried messing around with APNs, and it did nothing besides disable my data when I messed up and had to fix it with an EL29 boot, PRL update, and nandroid restore... I suspect it has something to do with APNs/DU settings.
You can help me out by confirming if, you're running DU, you have this issue too. This way I know it's a problem with my APN/PRL/modem/life.
Thanks, xda!
I had the same issue when I flashed DU. What worked for me was an app called Roam Control. Just select "roam only" wait a few seconds and then select "automatic." After doing that roaming should work as normal and if you go back to the mobile networks screen you'll notice that none of the radio buttons are ticked. Roam Control somehow overrides them.
Roam control is $4 and isn't in the play store but its well worth it.

Good luck
I have that problem with any derivative of cm10.1. I also have a terrible experience with any modem I choose. For me, it was flashing the 00001 prl and always roaming (it does this automatically no matter which seeing you have checked under cdma settings in your rom) on Verizon in order to solve. This is the only way I can survive without losing my temper and smashing my phone since sprint sucks nuts. You can verify it working not only by the better reception, but also the app "not roam control" in the market. This one is free, and just shows you what carrier you are currently using for voice and data services. Mine has been Verizon ever since I flashed the prl, and I am once again loving my phone.

Well, my roam settings showed that they would "stick" but by checking my service status (not roam control), said I was still using sprint network. Only until I updated prl did I get something worthwhile. It seems my phone likes aosp, cm 10, du much better than touchwiz, but touchwiz was in fact the only time roaming would actually work. And it was shotty at best. So by using the "always roaming" prl, I don't have to make any changes to anything any longer, and phone is working great. Just thought that might help you out as well.

I have just moved from the Virgin Moto Triumph running CM7 to the Virgin Galaxy S2 (E4GT). I loaded DU as my first custom ROM and am noticing horrible service no matter what modem I install. I have also tried modifying the roam settings because Sprint sucks around here.
May I ask what I need to do to load this 00001 PRL you are speaking of? I would be interested to see if this would help my service (or lack thereof). TIA.
