[Q] Roaming not authenticated? - EVO 4G Q&A, Help & Troubleshooting

So, while I work I bounce around Sprint and Verizon since I'm up in the mountains of CA. While I was roaming I tried to make a call and I got told by the lovely Verizon automated Failbot that my phone was not authenticated to roam on their network. I previously had no problems with this. Since then, I've only made one change to my phone (besides some apps) and that's updating my PRI to 1.40_003.
Can someone who's roaming and used the updated PRI method confirm/deny this? If it turns out I'm wrong, how do I fix this? Verizon gets decent signal up here whereas Sprint gets crap until I go about 15min down the freeway.
Any help would be appreciated! Thanks!

[Q] International roaming block

Sprint service is crap where I work (outer areas of Detroit), so I am using Roam Control for when I get near work. Most of the time I get a tower in the US, but every once in a while a Canadian Tower appears.
Sprint has told me to update the PRL (done 01115) and has tried to block the international roaming (didn't work), so now I am here to ask the experts.
Is there someway to prevent locking onto an International Tower?
I am running Syndicate Frozen ROM with Emotionless Beast Theme (which deserves more thanks than I could give, since this is how I figured out I was on international tower).

I think that your best bet is to enable the Roaming Guard.
Now I would advise you download ROAM CONTROL (http://www.appbrain.com/app/roam-control/com.vuvuzela.roamcontrol) and force the network to HOME ONLY and that might work out for you
Let us know.

I have and use Roam Control so that my phone will work at/near work which I want. I would say 95% of the time at work, I am on a US tower. I am just looking to prevent the other 5% from charging me International roaming charges.

To what setting you have it? Home Network or Automatic?

When I am using it, it is on Roam Only.
When Emotionless Beast said "International" instead of its usual "Emotionless Beast" on the lock screen, I would think that somewhere in the programming it the phone knows where it is at, and am simply wondering if there is a way to block data while on international.

Not sure what it is all about. The last link in this thread http://forum.xda-developers.com/showthread.php?p=13153111 talked about this PRL, so I manually loaded it.
Bumping, since my phone is seems to go into International roaming anytime I am at work now.
Staying on Sprint Network only is not something that I want to do. After paying a lot for the 4 phones I have with Sprint (and the fact I do not leave the US) I do not think I should have to pay for the Canada Roaming addon.
Sprint told me update the PRL ("to one that is greater then 64" was actual quote from the rep) and this will end me getting an International tower.
My PRL does not update automatically (don't know why, maybe due to Syndicate Frozen rom), so I manually updated to 60676 and still get the international tower.
Does anyone have any other ideas on what I can do?
If it is only at work you are concerned about maybe you can talk your boss and Sprint into setting up an Airave there so you won't roam at all.
Do you BONSAI?
Didn't think about that. I will have to talk to them about it.
So after many conversations with Sprint and many bill adjustments, we came up with the solution of turning off Data while roaming on my phone. This still allows me to be contacted by texting and voice.
Allthough still not happy that International towers cannot be turned off completely, at least my kids are able to get a hold of me.

Can't Activate because of perma-roaming. Need help to fix please.

So I got my new Xperia Play last night and found it has a very odd issue, it's always roaming. I don't really care except you can't activate a Verizon phone while roaming. I do the *228 and it eventually says "activation failed"
I live in downtown Portland OR so there is no shortage of VZ towers and my roommates phone on VZ gets a non-roaming signal just fine. Also when setting network to "home-only" and forcing it to use VZ towers I get no signal. I can't make it into VZ until Tuesday to get it sorted out so I was hoping someone might have an idea on how to fix this.
and I could probably find a phone to have customer service deal with it but I really enjoy working with phones and I haven't seen this issue before so I'm curious about a solution. Thanks for any help you can give,
- Jon
I ran into a similar issue, try turning on mobile broadband and then turning roaming to home only...

The mobile broadband is on, but when I set it to home only I get no signal at all. I still only get a signal with roaming but I cant activate with a roaming signal.

[Q] Signal Dropping Bad

Me Epic Touch that is using Verizon Towers is constantly dropping signal, I have tried every modem from EK - FD but nothing has seem to help. I tried with Page Plus original Prl which shows roaming and didn't help and also loaded other Prl's that doesn't show roaming all the time that Straight Talk uses, but it does the same thing. I have had many Sprint Phones activated on Verizon side and never had any problems like I am having now and My Cousin has The same phone also which is on Page Plus and his phone behaves the same way. Was wondering if any of you that have this phone and flashed it to Verizon are experiencing the same thing? If anyone has any opinions or could weigh in on what I might be able to try or maybe tweak on this phone that might help I would greatly appreciate thanks. Forgot to mention that I have tried both stock and Ics roms and when signal drops it will have a circle with lone threw it but I don't have to reboot phone signal always come back seconds later but trying to hold a conversation on this phone is bout impossible without 2 dropped calls in a 30 minute period.
Is the phone activated on Verizon or are you just using their towers for some particular reason? Keep in mind there are issues outside of the phone that may affect connectivity - I just had this happen with our local Sprint tower last week. Took a week for Sprint to confirm the problem was the tower and fix it.
If you made a nandroid backup before you changed the prl (witch is what you should do before messing around with anything to do with your phone) flash back to it, see if that helps at all.
HTC Hero -> Epic 4G -> Epic 4G Touch
It is activated on Verizon unlimited plan. I also have a nanroid back up of the stock rom behaved the same way. At first I though it was Page Plus being I never used them and gave them a try instead of always worying about data issues with ST. I let my time run out on Page Plus and and switched to Verizon new 50 unlimited pre-pay but still acts the same way.

[Q] Any ROMS That Have Forced Roaming on EpicTouch

I'm sorry if this was covered somewhere else but I've been unable to verify which (if any) ROM allows you to force roaming. I'm on Sprint and go to the San Bernardino (CA) mountains every weekend where there's almost no coverage. My sons on Verizon and his phone not only works but also has data coverage up there. I have another 1.5 years left on contract (5 lines) so don't suggest I change to Verizon. That will come at the end of my contract.
I purchased Roam Control but the developer is not supporting the app and the program won't register to allow me to use it. I'm not the only one with this problem.
Does any of the ROMS developed for the Epic 4G Touch on Sprint have the ability to force roaming on Verizons network? My phone is stock but rooted. I have flashed different business PRl's to see if any of them would enable the phone to roam with no luck. Tried going where there's no signal, turn off phone then turn on to see if the phone would automatically connect to the Verizon signal once it see's that there's no Sprint signal but no luck.
We have no internet or phone service so wifi's not an option. I can walk around and eventually get a signal to make a call but have no data at all.
Walking around to find a signal is not always an option.
I've been a lurker on here for years and figured if you guy's don't know, then nobody will know.

Thank you. Roam Control now works. I'll try it out next weekend and report back so anyone who is following will know the results. Thanks again.

Samsung Verizon S4 SCH-I545, OS 5.0.1, on Tmobile network, very sporadic signal

Bought a refurb SCH-I545 Verizon to run on Tmobile network. Created a new APN and have things working but signal is rather poor. Seems to hunt around a LOT from no signal to full signal and data 2G to 4GLTE. Not consistent at all. Many calls being missed and sometimes trying to call out, I have no signal. Tmobile is out of ideas. I think I have most settings right but something is either wrong with the phone or a setting is off.
Can anyone confirm?
I am considering rooting the phone to delete all the bloatware? I am not sure if the boot loader will be opened? I would not mind losing the Verizon boot screen and the "sim is not verizon" BS....
At first, tmobile thought the phone did not support 1,9ghz but all documents I can find say it is fully supported. Do I need some radio apps?
