[Q] force roaming

is there any way for me to get my stock 2.2 epic 4g to force roam without rooting the phone?

I don't believe so. In fact this issue is what helped nudge me to learn to root in the first place. Do it, you won't regret it. It gives you so much more control over your phone.

You should be able to change to a verizon prl without rooting. There's a thread in dev section on how to update it manually. Check it out might be what you need.

Only problem is, will they get pinched for doing that by Sprint eventually since it's going to be on Verizon more or less always. And, it'd prevent them from getting proper data service. Unless there's a way to switch PRLs on the fly I'm not aware of.

No way to switch on fly and I've been using a 0001 prl for over a month now. And used roam control constantly for about two months before that and never had any issues with sprint.

I read somewhere that we get 800mbs a month on roaming before you get flagged, then i think they offer you an airrave cell tower, after that i think they terminate ur contract (free of ETF *wink* *wink*)
EDIT: which is why Roam Control rocks, solid 1x is better than nothing

Correct and people have been terminated for that reason. Just root and get roam control from the market. Its simple too root. And roam control works great. I find myself in areas with 1 or no bars of service and goes up too 4 or 5 when roam control is on

Should I be expecting an Airrave then, I stream hbogo and am on xda and other games all the time on a different prl? Can't beat getting free stuff. Only thing is it won't help me out at work

Roam control

Has anyone got it to work on the Sprint GN? I'm trying to purchase it right from the website but it fails every time. Has anyone been able to purchase it recently?

It's never worked on my sprint gnex. Always force closes when selecting.such a shame too because it seems like this phone will do anything to not switch into roaming

Go to the sprint galaxy nexus thread they found a way to write Verizon prls and corparate prls easily that way you can choose to roam and what not and its free

Yeah, I've seen that but I don't want to roam all the time and changing prls isn't exactly flip of a switch.

Actually it is. Go check out that thread, they detail how to use anycut to make a shortcut on you home screen for flashing the prl. Takes 30 seconds to do.

Actually its not. The flip from one prl to another requires phone reboot. That's just way too long. I don't mind slower speed using my current, normal prl. I would just like to force it so my phone is not going crazy trying to hold on to a signal. I know CM7 had that feature. I only wish they added this to CM9.

It literally takes 30 seconds. Its not even a full reboot, and it's currently the only option for doing what you want so either try it or don't.

In order to flash a prl, I have to rename it TEST.prl. Is there a way to keep the prls with their proper names so it's easier to switch from one to another?

You really can't but I imagine someone can write an app that just writes the test file and runs the PRL flasher. The phone really does not have to be rebooted as the sprint update does it without a reboot. It would be nice to skip that need.

Hopefully somebody that codes will step up. This is the one feature I'm really missing after moving over from the EVO.

flashing og evo to verizon???

sorry if this is posted, if so please delete mods, and PLEASE provide a link to that thread , anyways, how can i flashed a sprint og evo to work on verizon network? my mother in law wants to use her og evo on her verizon account, thanks a bunch!

Its not gona happen. Verizon won't let you. The BEST you can do is force roaming on verizon towers, via flashing verizon prls [can be found in general with a search], though some users have been booted for excessive roaming.

Yes, flash the 00001 prl and you will use Verizon's towers. Just switch back and forth every few days so you don't get the boot.

well that sucks...... i thought since people can flash to metro and boost, one might be also able to flash over to verizon oh well, was worth the try!

PRL Archives

Take a moment and read these articles before reading any further: What is a prl? Part 1 Part 2
This article also was helpful for me when I changed my PRL before: Wonder How-To
You will need to know your MSL
prl series - acct- device
25xxx = residential acct - lte/800smr
24xxx = business acct (some 3g roaming added) - lte/800smr
55xxx = residential acct - worldphone lte/800smr
56xxx = corporate acct (vzw 3g roaming) - worldphone lte/800smr
16xxx = corporate acct (vzw 3g roaming) - lte/800smr
11xxx = corporate acct (vzw 3g roaming) - no lte/no 800smr
12xxx = corporate acct (vzw 3g roaming) - no lte/low priority 800smr
60xxx = residential acct - no lte/no 800smr
21xxx = residential acct - no lte/low priority 800smr [EDIT: 21100 LTE works for Spark Ready/Triband phones]
51xxx = iphone5 - low priority 800smr

Every Sprint PRL
First I would like to say be respectful to Moderators. They make XDA a great place for all good members. Don't let what happened to me, happen to you.

Can we flash Verizon prls the same way? I loved doing it in my og evo and really miss that option! Tia

Yup. There are a couple in there that will enable 3g forced roaming on Verizon. I'll update OP to list them

To undo the Verizon prls ,do we just update profile, then prl in the settings? Tia

Yeah you can do ##786# but that wipes your data. I know there's another code to do a hands free activation. I can't remember it now

Great post. I need this because my parents live in a former Alltel area and I get zero coverage for Sprint and will not access the tower. If you want to go back to original prl...search for 25006 and follow same steps in OP.

We call him St. nicholaaaas around here. I went back to stock and flashed 24006. I swear 3G is better even on stock. I don't know about switching but I'm getting better signal and speed. No Sprint 4G in my area.
I can speak to the performance on CM10 yet because of course after flashing stock I forgot to say yes to disable stock restore boot so trashed all my nightly backups and have yet to get a good nightly install. But hey, I'm getting very adept at restoring stock. I'm glad I went back for another reason. The pleasures of CM10 are more evident after having gone back to the original Samsung rendition.
Thanks for the PRL.

I write ny prl by using any cut. I create a prl write short cut and rename the prl to test.prl . Might be simpler no msl required

##72786# will initiate hands free to change prl back.

Flashing zips in rehab!!

Thanks for this. Awesome having PRLs! The Verizon ones in Jax, FL go LoS often (connected to network, but loss of data connection). I haven't tried 01337 yet, though. I don't think LTE is affected by PRLs due to it being a GSM technology.

how do I know which PRL is on the phone right now?
also, lets say I flash this, if I do an update prl from settings, will that just take it back to stock or rather released version? or once I do this, it'll break that feature.

To see what PRL is currently on your phone go to Settings>About Phone
All you have to do to revert back is do a hands free activation

No need for a hands free activation, you can do as you mentioned and just go into your update PRL from Settings and get it done that way to get back to your 'stock' PRL.
From my experience, disabling data first will cause this to stick more times than not.
As another guy said, use Google to search for the anycut apk and you can create a shortcut that way. It's listed as 'PRL Write' within the app. Once you do this, you can just click that shortcut, hit the button and the phone will reboot. Not a big time saver, but one nonetheless depending on how often you're planning on using this.
If you use the 00001.prl (VZW only) it will show up as '1' in 'About Phone'. The preceeding 0's are omitted for some reason.
For me personally it's the only one I use as Sprint doesn't have a roaming agreement with VZW in Chicago, so if I have a bad signal, this is my only choice.
For those of you just changing a PRL to enable 3G data when you roam, let's say naturally, you probably won't need to revert back at all. In that case, just freeze System Update so Sprint doesn't roll you back after a day or two.

Roaming on Verizon, with 3G Data&MMS?

I'm interested in being able to roam on Verizon, since Sprint is a POS at my school and home, and I'm constantly loosing messages, and data speeds are very sad. Anyways, I did a quick search and found a guide on changing the PRL to Sprint's "Corporate PRL" which apparently grants roaming with 3G data on Sprint, but it seems as if though that guide is old (Sept 19 from last year) and I'm not sure it'll work on my ROM (AOKP JB) So, does that guide still work? Is it safe? If no, what are my other options?
Also, how much minutes/texts/data usage would piss off Sprint? I've been meaning to switch for a while now...

I don't want to get too deep into this since there is a PRL thread in the forums, but doesn't that one force you to roam all the time? Sprint has a roaming limit of something like 200MB a month; if you go over that they can and frequently will cancel the rest of your contact. Some people do that on purpose, which I don't recommend or advise. If you just want to use your phone when you don't have much of a signal, use a PRL like 11115 along with the app Roam Control, that way you control when the phone roams.

yes.. oooo2 or w.e is a verizon prl roaming 100%.. i used the sprint corp prl i think 11124 or something which wasnt roaming while set to home only. but would have verizon 3g while in roam only with roam control which is compatible with jb now... however if using verizon eventually u will get a call from sprints roaming team.. and the prl thread is right. just need to be on a tw rom and when u go back to a aosp rom prl will stay until u update it

I use the 11119 PRL that works great when I'm roaming... I roam on Verizon with 3g data and everything, but I'm on Sprint the rest of the time. It works great.
