It's a guide for that specific rom - I haven't tried it on an AOSP rom but I would imagine there's a way to change into diagnostic mode and get your MSL for any specific rom. I just posted it as a starting point, sorry about that. Anyway, once you get that out of the way, the CMDA workshop method shouldn't be ROM specific. I don't even think you have to be rooted, actually. Sometimes I use the app AnyCut to access service menus I couldn't otherwise, although there's no guide for that.

Sprint MVNO PRL?

I've got PRL 40450 for Sprint's MVNO-carrier customers (Virgin, Boost, etc.)

Full list of mobile virtual network operators here on wikipedia

Doubt this PRL is anything but restrictive, but hey who knows what might happen. This is all in the name of SCIENCE!

I'll let Whosdaman confirm the validity of my file here, but i snatched it from my phone per his instructions in the OP.

Also, for those running AOSP-based ROMs (CM9/10, AOKP, etc) then check this out:

[SOLVED][AOSP] Enable USB Modem/Diag Mode on Samsung CDMA Devices

This has been solved for the Samsung SPH-D710 Epic 4G Touch, Samsung SPH-L700 Galaxy Nexus and Samsung SPH-L710 Galaxy S III.
[Samsung Epic 4G Touch] Hero_Guy:
Using the 00002 PRL, will the data used on that PRL go towards my roaming data? I'm getting speeds there that I haven't gotten since I was on GB
[Samsung Epic 4G Touch] Febby:
Yes, be careful if you choose to use that PRL. That PRL by default is forcing your phone to verizon without warning. Sprint has been known to kick you off contract without warning lol.. some never get a warning or kick.. *lucky*.
[Samsung Epic 4G Touch] Dudebowski:
IIRC, Mod VZW PRL's are Verizon towers ONLY. Sprint will eventually send termination of service letters. You might want one if you're trying to force them to breach your contract to move services.... otherwise, YMMV.
[Samsung Epic 4G Touch] Hero_Guy:
Alright thanks. What PRL is everyone getting the best results from that are near LA. I used to get speeds

around 1.8 MB down and now I don't thanks to the PRL update and ICS. I've reverted back and haven't gotten the same results. The bet ones so far are the Evo LTE PRL and the PRL prior to the update (which is the one that used to be best for me). I miss my insanely fast speeds for sprint.
[Samsung Epic 4G Touch] Febby:
Sadly no PRL will... we have to wait till sprint fixes their issues on the network... which network vision should do, who knows though. NV only made my home signal awful and slower.
[Samsung Epic 4G Touch] Hero_Guy:
Thanks. Whats irritating is that they've been doing the NV update here for months and I think they're done. I used to only get data speeds of .06 Mb/s and then I used to get up to 2mb/s regularly. Then when they updated our PRL to 60690 and updated the SII to ICS, it all went to crap. I tried reverting and nothing. Hell, I used to get 16 mbs on 4G, now I'm lucky to hit 1mbs
[Samsung Epic 4G Touch] Febby:
Yup I can say the same about this.. my Wimax is around 700kbps to 1300kbps which is acceptable to a small degree. I'm honestly waiting for the phones supporting the 800mhz lte band and 1900.. till then wimax and wifi shall be my best friend lol
[Samsung Epic 4G Touch] AestenD:
PRL has absolutely 0 to do with Wimax speeds. Only deals with the evdo/1x tower connections. If you've seen that much decrease in Wimax, try rolling back your modem.
[Samsung Epic 4G Touch] saiko*:
Its funny because ppl on the epic touch 4g prl thread just talked about LA..

I know ppl are reporting slower speeds with ICS update etc...but for the LA area.......i think the network as a whole is slow as hell right now regardless of ICS. By slow as hell...I mean sometimes my speedtest won't even finish. To make matters worse..people living in "surburban" san fernando valley has it even worse. Only a FEW wimax towers up towards the south side only (btw PRLs don't have wimax towers as part of it) and seems like barely any sprint towers...I suppose not densely populated enough to be worthwhile. We can't even force roam because vzw 3g towers are just as ****ty so the hacked 00002 roms don't do anything either...

[Samsung Epic 4G Touch] gatesmarch123:
Can someone please tell me how to get roam control working? I'm on stock rooted gingerbread el29. Do I have to use a hacked prl? I was using 11115, but force roam wouldn't work at all.
[Samsung Epic 4G Touch] tensux:
the forced roam would not work? or the prl 11115 didnt work? not all prls work in every area, also it has been said that on the paid version of roam control works these days, the free one that was oth there and the hacked versions will not work.
[Samsung Epic 4G Touch] konaman:
I find that it works best on stock prl. Make sure u have it set up correctly by checking samsung in the settings. Then tap roam only and u should lose service for a sec as it switches over to roam. That's all I have ever done and it has always worked with 4 different phones.
[Samsung Epic 4G Touch] Dalmus:
There's really nothing to "get working" other than telling RC you are using a Samsung device.

What do you mean by "wouldn't work at all?" Did your phone not switch to roaming (triangle above the signal bars), or did it switch to roaming but 0 bars, or did it go to no signal (circle with a line through it)?
[Samsung Epic 4G Touch] AestenD:
Why would you use with stock PRL? The whole reason we use roam control and the other PRL's is to get 3g roaming.
[Samsung Epic 4G Touch] sohungry:
I'm in Gainesville, FL. I flashed 12124 and the results are terrible compared to 61087 or even 21090. For some reason, Speedtest keeps using towers in Kansas...any suggestions on which PRL I should try? I have an Evo3D, if that makes any difference.
[Samsung Epic 4G Touch] Godthing247:
Can't receive calls

I updated my rooted Epic 4g Touch to a new PRL and cannot receive calls. I can place calls, place and receive texts, but incoming calls go straight to voicemail. I have tried this in 4 different locations. This happens on any PRL i've tried (00002, 11115, 11119, 00001) When I switch back to Automatic using roam control, it works fine. Any thoughts on how to fix this?
[Samsung Epic 4G Touch] AestenD:
Speed test connecting to Kansas is due to your location/GPS but giving you a good location. Nothing at all to do with the PRL.

[Samsung Epic 4G Touch] elliwigy:
you said that a few months ago.. not to troll but where do you get your information? for the most part only reliable information youve given is from prls that already exist.. you dont seem to be an expert and know sprints plans besides stuff your reading from there site and on the internet.. you also said wed see a huge increase in 3g everywhere and they would be using other frequencies.. this is a lie. they have same prl and same crap service where im at for over a year now.. ill believe it when i see it happen.. only improvement i see with data is when i use wifi lol. other than that the "now" network seems to be same old 1x speeds for over a year for me here

Lol. You can't reply on that speed test app. Especially if you are not using I right. Look at the server you are testing. Now try hitting tool in the app and switch the server to a Boston one
[Samsung Epic 4G Touch] Whosdaman:
Lol, you do know that I said by the end of 2012. And guess what, it's only September. Not only tht, but Sprint just confirmed basically all I said in that press release.

To be honest, I don't care whether you believe me or not. I tell you what I know and so far everything I have said still is true. The plans I was talking about will be finished by the end of 2014. Major network upgrades on 99% of towers don't occur over night. You are ignorant for thinking that, and should reread everything I said awhile ago again.

Again, there will be numerous prls rolling out as these 100 cities are lit up. And guess what, if you aren't in one of those areas, you aren't going to see improvements yet.

Thanks to the OP for posting the instructions. They worked well. I am on the 11121 PRL and it seems like I didn't get 3G when I roamed and I get slower 3G speeds/ping when I don't roam. I think I might try the older 11115 PRL to see what it does.

Got a call from Sprint today....

I live in the San DIego, CA area. I have been using the 0002 PRL [Verizon] for the past two weeks. I was on the 01337 [Verizon (mod)] for a little over three months before that using between 500mb and 1.3GB of Verizon data per month, and 0 Sprint data.

I got a call around 2pm this afternoon. The woman introduced herself as a Sprint employee. She then told me Sprint has a 300mb / month allowance on roaming data and I had exceeded it. I feigned ignorance on the 'technical details' and lied about a friend at work' changing some settings for me.

She guided me through the steps to change the settings back, which i faked as I'm on a CM10 nighly.

I do not know if I would be let go without an early termination fee if I stayed on the 0002 PRL. I switched back to a TW ROM, updated my PRL, and am back on the stock PRL. It was nice while it lasted. Switching to 11119 (Mobile Broadband Corprate Sprint PRL), use roam control and monitor my roaming from now on.

Happy Thanksgiving everyone!
[Samsung Epic 4G Touch] rg2:
The attachments to this post don't completely correlate with the information in the post; specifically, there is no attachment for "21086" or "60686" as I am interested in switching my PRL back to a Sprint-specific one to see if I can get better service on a Sprint-native network and if/when I start to reach limits on my minutes and data. Also wondering about what PRL's I can use on my phone (NS4G) that will still show up as being used on Sprint without any complications. Thanks for any/all help!
[Samsung Epic 4G Touch] AestenD:
The corporate prl have other networks towers able to roam onto with 3g, versus 1x only on the non corporate. You use roam control to force roam when needed/wanted.

The hacked Verizon prl are ALWAYS on Verizon, even though your phone will say that it's on home (Sprint) network.
[Samsung Epic 4G Touch] rg2:
Thanks for the reply! I was just going to edit my post as I made a mistake in that there were two PRLs (21086 and 60686) that don't have attachments and I was wondering if those were available to use.

One question, If I use the corporate PRL will I regain my Sprint plan benefits (i.e., any mobile/any time et al.), with only the boost in roaming data? That seems like the best of both worlds at this point.

Again, thanks for the help!
[Samsung Epic 4G Touch] AestenD:
Yes, the only thing that makes the corporates different is the 3g roaming vs 1x on normal.
[Samsung Epic 4G Touch] bigmikehd2:
It didn't matter which prl I use, I always only get Verizon 1x. I've tried them all
[Samsung Epic 4G Touch] etirkca:
You need either 11xxx or 12xxx. If you're using Roam Control, it forces the GS2 to roam on band class 0 (850 MHz). Verizon doesn't have 850 EVDO coverage in some areas.
[Samsung Epic 4G Touch] colonel.shepard:
Our phones are capable of roaming on which other vz bands
[Samsung Epic 4G Touch] bigmikehd2:
They probably don't have it in my area because like I said, I've tried them all.

atlast! Flashed the 11119 PRL and my phone is now connecting to verizon 3g towers! My E4GT is running the latest ParanoidAndroid with a EL29 modem.
[Samsung Epic 4G Touch] juryrigger:
Is there a consensus as to the best overall PRL here? I take it that it is between:

Sprint corporate

Sprint corporate with network vision

Modified Verizon

On its face, the Verizon one seems the obvious choice, as Verizon's network is known for being the best. Will Sprint boot you for using the Verizon one since you would always be Verizon's network?

Also, anyone know how to enable dialer codes for an Epic 4G running CM10.1? If not, is there some kinda of work around to manually updating the PRL on phones with Cyanogemod?

Lol, you don't know who Whosdaman is right?

And yes... I was pretty famous back in the day. I've been a developer for nearly 5 years now. Started with the HTC Vogue. I was a Sprint representative and I had numerous sources. I provided leaks for official ROMs for all he sprint devices. Literally all of them.

I was the moderator for the Epic 4G and the Glacier along with other minor devices. I changed accounts for 2 reasons...

1. Name association with BriefMobile. I became Managing Editor at BriefMobile.com and I wanted a separate account to represent that side of me.

2. Whosdaman was attacked and crucified. He later crushed the group that will go unnamed and nearly destroyed them. But I had enemies with Whosdaman and I wanted to kinda start over. Some didn't like me from moderating, some from the attacks, some from leaks, and some from competition.

I even found out that there were people who felt threatened by me and extremely jealous. Kinda shocking.

(Hidden reason, he's really my evil twin brother. Lol )

[Samsung Epic 4G Touch] chrisnosleep:
OK, I'm in south central Kansas, near Wichita. I installed 11115 a couple days ago and can't decide if it's helped or not. I've only seen the phone switch to roaming 1 time.

My issue is this: I have a decent Sprint signal at home now that I have an Airave. However, at work they have a repeater set up and aimed at a Verizon tower and I hardly have any Sprint coverage there. I would like to be able to roam over to Verizon quickly and efficiently when I'm at work, but it seems like my phone fights going to roaming with every last breath.

Can anyone advise?
[Samsung Epic 4G Touch] Whosdaman:
The problem is about when you switch to roaming, it's if you want to force yourself to roam. When you have terrible Sprint signal, we force ourselves to roam. When we do we like to keep our 3G data speeds. Stick with 11115 and you'll be fine.

I have lots of tests I can upload if you want to add them to your data. I did about 3 tests per location, and multiple days.
