Force roam with roam control

Hi
Has anyone been able to get there epic to force roam using roam control on any of the new ext 4 roms.

Works for me using nebula rom and ext4.

I swear I was on that rom yesterday and it didn't work. Ill give it a try. I know for sure I tried super nova, cm6, and quantum and all 3 didn't work. Btw I'm in aguadilla PR and my wifes EVO is working fine using the roam control here. Fyi if your coming to this part of PR roaming is a must to get the best 3g.

It was my understanding that at least with roam control on the epic, you can only get a 1x forced roam. Roam control only uses verizons towers. The best speed I get while using rc is 150kb down.

Here in aguadilla PR you actually get true 3g roaming 800kb. When im not roaming im lucky to get 60kb.

I just tested it working fine on mine, Quantum Rom 2.7 EXT4

I used to use it. No, it isn't verizon only roam. My phone roams on to us cellular. To figure out what network you're on, dial a number that requires an area code without it and the message telling you that you misdialed will tell you the carrier.

When I press *2 to contact sprint customer service at my house it connects me to verizon customer service. You might wanna try the same to see what carrier your roaming with

Strange why I can't get this to work. Everytime I set it to roam only I just lose the connection completly. Anyone get this working on supernova rom?

I just got it on my stock DI18 rom and it works beautifully! Sprint sucks in my area (I'm lucky to get 1 bar and dl speeds at dial up speed), but now I'm listening to pandora and browsing xda! I love this app!

I've been using Roam Control since the day it started supporting Samsung phones. It has consistently worked for me regardless of the Rom, kernel or filesystem I'm using.

I'm in the middle of a cinder block building with NO Sprint service...Works great with Nebula ROM, except for texts? Internet and e-mail are fine, 3 bars. I stream stream on-line content without a hitch...can't send or receive SMS. No clue why.

So guess what.. I'm back in nyc and roam control works fine here!! and I didn't change my rom. So it seems that you can't force roam everywhere on the samsung epic for some reason. I wonder if it has something to do with the PRL. And the thing is when I was in Aguadilla it would roam on 3g but of course only in automatic. So one would think that the PRL is ok. Anyone else in the west side of Puerto Rico near Aguadilla try using roam control with there Epic.

Roam control works great here...blazing on VZW EVDO. I use it all the time with the mess they have here on EVDO...50-60 kilobit if you are lucky on Sprint.

I tried out roam control and it seems to work. The phone seems to switch and everything but cant find a signal and I just get the no signal icon. Any ideas?

I still can't get 3g speeds while using roam control. At my house I get a more consistant signal with roam control on however my download speeds never get above 50kb. When I get a sprint signal I get 600kb+ When I purchased the app I was told that it only accessed verizon towers and would only get a 1x signal because sprint doesn't have a 3g roam deal with verizon. However people are saying they are getting 3g speeds from vz towers using roam control.

How do you know if you are roaming 1x or 3G, for some reason on my epic I am getting about 120kbps download on roaming with 4 bars and it says 3G?

Download "Mobile Signal Widget" from the market and it'll tell you whether you're connected to to 1x or 3g. I'm currently roaming on 1x, but at least I'm getting (good) signal at my house!

MetroPCS blocking data on flashed phones

I can confirm that MetroPCS is blocking flashed phones from using their 3G data network as of today, November 5, 2012. I had my Epic 4G slider flashed to Metro around 9 months ago. 3G worked up until today. I let my service lapse (for all of 12 hours) and after I paid to have it reconnected, my 3G no longer worked properly. It is actually still connected to the Metro 3G network and 3G shows in the top bar, but the only webpage accessible is a page titled "metropcs_tethering_message" which states:
"Per the Terms and Conditions of Service, Tethering / Mobile Hotspot is not currently supported. Please visit --- for terms and conditions of use."
To be clear, I am not tethering or using the phone as a hotspot... just trying to surf with the phone itself. The days of flashing to MetroPCS and using data seem to be over. I wonder if it has anything to do with their impending merge with T-Mobile?
Time for me to find another inexpensive call/text/data solution.
[email protected] MetroPCS!

Its been like that ever since they blocked tethering.. some cities were opted out from 3g before tethering was blocked. Requesting the desktop version of a site on a metro phone makes that same message appear. It's likely to be an easy workaround but worth the trouble? Certainly not. I suggest you take a look at the virgin mobile guide in my sig.

Well, an interesting development...
After buying a new (to me) GSM sim-based phone (LG Optimus G2X) and signing up with SimpleMobile, I was prepping my Epic 4G slider for sale and re-flashed my rom to the same custom rom I had been using for many months (ThunderHawk EG22 with Nubernel 2.6.35.7 kernel). After I did this, my data connection started working again. Might not stick, but it's been on for a couple hours now.
Now, this wasn't some glitch or bug in my system that caused the data connection to stop working as stated in my original post. I confirmed with MetroPCS that they were actively blocking my data connection, so it wasn't something wrong with my phone. However, after reflashing the rom, it works again! I'm still selling the phone though and moving on from GhettoPCS.
I'm posting this so anyone else who's had their data connection blocked can try reflashing their rom (even the same rom, apparently) to try to get their data connection back.
But once again, [email protected] MetroPCS for blocking flashed phones! Why do they care where we get our hardware to use on their shhitty service?

That may be the placebo effect, many outdated Epic Roms improperly displayed 3g icon when it was in fact 1x.. you should do a speedtest and verify its Evdo Rev A or Evdo RevB and not 1x..

ATT GS3 losing Data Network randomly

This is the Task650 and Ktoonsez AOKP. VERSION: d2att(4.1.2 JZ054K) from December 2nd release.
My data network goes in and out at random. It actually started happening about 4 days ago on an older build by Task650 & Ktoonsez but I saw the new one so wiped dalvik and Partition cache and rom'ed. Even after flashing the new ROM, data is acting the same way. It is completely random, happens when the phone is in use or when it is locked. I can tell when data connects for short spurts because I hear the notices for new emails. All in all today, I've maybe had 5 minutes of HSPA/3G data and the rest all I have is cellular network for calls. reception strong, and I am in areas where I always have good connection and speed.
Any ideas? Kind of frustrating if I am out to lunch and want to catch up on things (stuff is blocked at work). Also I am paying for data I can't use :/

fully wipe and reflash.. try a different modem

I am admittedly new to flashing, I just assumed everything was in the package. I flash the ROM and Gapps, is there a source for different modems?
This is definite disconnect of data DHTP. Can't get anywhere, and there is no symbol where there usually is on the reception bar. When it comes back for brief moments, it has either HSPA, 3g, etc.... on the bar.

are you able to send and receive calls? text?
I flashed that rom three days ago, and i had to replace it via warranty. it showed it had signal, but couldnt make any calls or text at all. then i Odin back to stock never worked again.

Don't think it has to do with any rom. Noticed that my wife's sgs3 has had a problem sending and receiving texts and the network drops a lot as well. She is completely stock with the jelly Bean update. My network has been a little suspect over the last few days also. Might just be the service.

Hey Guys, I may have found the culprit...sort of.
The wife has an iP5 and she said to me while we are driving to a holiday party 'I finally have official 4G LTE on my phone'. To which I of course ask what she means. Apparently the same day I started not being able to connect to data networks, is actually the day that ATT fired up their 4G LTE tower(s) in the Lehigh Valley area. When I do get data on occasion, it's when I bump down to 3G and HSPA. Unfortunately, the ROM has a bug where I cannot force it to look for just 3G, I go to save the setting and it immediately jumps back to LTE.
I may just have to flash to a version that definitely supports 4G LTE data. This issue occurred before I flashed to newest ROM, so it has something to do with the core build or modem that both versions use.
Ngriffin, if you find any successful modems please let me know. I like the ROM but I can't go without a data connection much longer.

So, for those who care, I flashed Gapps and also Flashed a new modem (http://forum.xda-developers.com/showthread.php?t=1831898) version UCLG1 and it's a no go. A few in my area said it worked great for them so now I am a bit discouraged. Northeast Pennsilvania Area.

LEM

LK3 -------------Works but only 3G data.

More info, tested using the Wife's Ip5 and realized we don;t have LTE at our house, so I'll have to wait until we get withing range of the LTE tower(s) to see if it has an issue. However, I now have data reliably.

That's normal. LTE is data only and isn't used for phone calls.

I've been running Task's AOKP on my SGS II and III for a while with no data issues. Check your APN settings. If you're in an LTE area, you should be able to sit on the ATT LTE APN and have no problems, even away from LTE coverage.

To update further, LK3 modem worked for a short while, but once I left the area of my immediate cell tower and it had to connect to another tower, it couldn't. I flashed ALL modems in my list a post above and NONE work. I'm kind of pissed right now.
Any ideas? I'll probably to a full backup and then flash a completely different ROM and cross my fingers. Is there an official JB stock ROM sans the bloatware that is stable and can connect to LTE (or any data network reliably for that matter)?

It was my APN *facepalm* Thanks for the suggestion. It was sitting on wap.cingular instead of the LTE and it was causing the issue. I'm on modem CLH1 and it is working, I have the 4G (3G) symbol now and data is connecting. Well, I learned something thanks! :victory:

I started having issues with mine about the same time. I haven't been able to figure it out yet. I had just gone to JB and flashed a new ROM. Then started noticing not just data being very spotty but also my calls (both incoming and outgoing) were very spotty too. Both seemed to only work about 50% of the time. I have since completely wiped and factory reset twice. I even Odin'ed back to a stock Rout66 jelly bean system but I still have issues
I have updated my APN to ATT PTA but that hasn't helped. What APN settings did you go with? Is ther some specific for LTE coverage? On the stock system now I can actually see the LTE icon when it actually chooses to connect.
Also, where did you find other modems. I was told in another forum not to flash any that weren't specific to Jelly Bean and all I have found is the stock I747UCDLK3 which is already on my phone. I did try flashing that seperately just to see if that would help but did not.
I need to get my phone working pronto as it is my main phone for both business and personal phone calls. Any help would be greatly appreciated. Thanks in advance.

When you're on stock, only thing you can do is check with your carrier and they'll either tell you that it's something on their end being worked on or that your SIM card is faulty.

This happens to me on tasks AOKP ROM at least once per day, but it usually only happens when I turn on LTE. Basically what happens is the phone has cellular service but no data, after a few minutes it comes back. What I have noticed is that its to do with LTE so maybe there's a problem with that?

Task's AOKP doesn't set the default APN to LTE for Rogers so you might wanna make sure it's your default APN.

LTE Connection Possible Fix

I have noticed that there are people starting to notice that that have LTE in their frequenting areas, but it's messing with their data once they leave these areas.
For me it was having issues kicking back to edge and even 4G signals would not pull any data, would simply say that I had no connection. Didn't matter whether rooted or not or which rom I was using.
Anyway,
I have discovered somewhat a fix for this issue.
Under Connections tab in Settings, click more networks, then mobile networks, then Access Point Names my Access Point Name was epc.tmobile.com.
I noticed in other forums their APN should be fast.t-mobile.com so I thought I'd give it a try and incredibly my results were pretty good. It goes in and out of LTE areas pretty smoothly in comparison to losing data altogether.
Give it a try and report back.
Thanks

I was experiencing drop of data connection for long period of time (at least 5-10 mins) every time I leave the house, losing my wifi connection. More than once it just won't connect at all for a good couple of hours. I just did a test today, messing with the APN, network operator settings and get it to connect to 4gLTE. Once and turn on and then off the wifi, I lose the data again. And it wasn't gonna come back.
The fast.t-mobile.com address seems to do the trick and I'm now immediately on 4gLTE after losing wifi. and the speed is AMAZING at 24,000kbps download and over 10,000kbps upload.
Thanks!!!

I already had that APN setting but I wasn't getting ant 4G LTE :/ must not be in my area yet. I'm in north Georgia

great find, I must have switched between 5-7 different roms trying to figure out why I'd lose data for up to 20min. after coming off wifi. Once I got reconnected to 4g I was afraid to even turn my wifi back on.

This seems to me to have just started recently, I'll have 4G but I might use the elevator at work and lose my connection, upon being back in service I'll be stuck on Edge for about 10-20 minutes before it picks up the 4G connection again.
I've been switching to Airplane Mode then back and that seemed to help but it doesn't any longer.
My APN is already fast.t-mobile.com, is there any other solution to fixing this?
EDIT: If I reboot my phone it connects to 4G immediately, and I'm using a Rooted Stock MDL Build w/ the Faux kernel.
Thank you!

What could be the issue ???

My GPS acts up in NYC area. This is on issue on every ROM. My google maps recalculates frequently, not keeping up with my vehicle on local streets and changes directions often. I've tried Waze and had similar issues. Google maps even tried to send me down a one way street once.
This happens mostly in the city areas. I previously moved from the state of Delaware where 4g is very limited but gps ran fine. In NYC LTE is everywhere even tho its very slow.
Is this sprint crap network or could there be something physically wrong with my note 2 ?
Any suggestions are helpfull.

Very interesting. I assume you are on a stock ROM correct? If so then if you haven't already, try updating your prl and profile in settings\more|\system update. Then manually restart your phone. You need to get in a location that is clear from obstructions to cellular signals when you do this. If you are downtown with buildings all around you then I would suspect it would have an effect on signal strengths and the ability to keep a reliable connection to data service and GPS... which also relies on data service. If this doesn't help then I would suggest calling Sprint and ask for tech support.

Have you tried the GPS clear data?

Thanks for the replies. I've done the updated the prl and profile many times. I even some to sprint all they offerred was to credit my bill 82 percent.
I will try to clear the GPS tho. I've never heard of this method thanks.
