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!

How do i Roam ? FD16

I'm on fd16. I'm trying to get the phone to roam but i don't know how ? I have roam control and i set it to roam only but nothing happens it's still on sprints crappy 3g network ? I hacked the prl to version 11119 aswell.

Did you actually buy roam control ? The pirate versions won't work for some reason ..... But otherwise make sure you check the roam options in settings etc they are off by default
Sent from my SPH-D710 using Tapatalk 2 Beta-6

I use roam control often. It often helps my signal get better, so I can make phone calls. However, it has never worked for the 3G.
One thing I absolutely hate about roam control is that is you have no data (and you don't have wifi access), you can't use the app, because it wants to check the license EVERY FREAKIN' TIME! So basically if your phone has no signal and you want it to roam, well guess what, roam control is NOT going to work because it wants to check the license, and since you have no signal/data, you are out of luck.

not all the prls work in every area, i use 01337-mod.prl and i get 3g on verizon, no other prl will do that for me
in fact with most other prls, even though i paid for roam control i will not get any data using them

The app should only check the license once and then cache it. If you are running an older version of the app, there was an issue where the android OS would return unreliable data on certain phones, and that triggered the constant license checks.
To the best of my knowledge, this behavior has been corrected in the latest version of the app, 2.2.0.

It had been fixed for sure in 2.2.0 I use RC all the time at work and I also have 11119 installed. I have full bars + 3G on Verizon and it is so good I need to watch my bandwidth so I don't get axed. If you bought it through Market, He has a tool that downloads and will verify your good and register the new one. Get the new version here: http://www.roamctrl.com/
Edit: It has worked on every modem since EL29 with no noticeable effect as I change to each newer modem.

[Q] Any way to disable 4G permanently?

Is there any way to permanently disable 4G functionality, by removing a lib or apk or some other method?
I'm using an Epic on Boost so 4G isn't an option, but I have still noticed that occasionally my phone will switch to 4G. When that happens I lose data and none of my background syncing works...
EDIT: Probably should have mentioned, I'm running The People's ROM v2.2.1.

Not 100% sure about this so I would wait for someone more experienced to give you another answer. But if you want, make a backup of your rom now and then use titanium backup and uninstall every app with "wimax" in its name. I do believe all the wimax stuff is 4G related. I could be wrong tho.
Sent from my SPH-D700 using XDA

Did you disable the Sprint Optimizer? Settings> wireless and networks> mobile networks> automatic connections.
If that don't stop it remove easysmart.apk from system on phone.

No 4G on boost?! Is that because you're not using a dummy phone with a wimax radio? I thought as long as I take the ESN from a wimax enabled phone, I'll be able to use the wimax feature. Am I wrong about this? How did you get your phone Epic 4G onto the Boost Network, mbellot?

My (minimal) understanding on the subject is:
1. The donor would need to be a wiimax device
2. In addition to the ESN you would need to also "move" the donor's wiimax MAC address on your Epic since that is what gets "activated" for 4G service.
I have seen topics on #2 floating around, some even on using an alternate wiimax service (FreedomPop, etc) by using the MAC address from a device on that service since they all technically go through Clear towers.
I've never felt the need to pursue wiimax, I'm on WiFi 90% of the time and the rest of the time I've learned to live with 3G.
To your last question (how I got the Epic on Boost), there is a very long thread in the development section here.
FWIW - I solved my problem by moving from TPR to CM11, WiiMax is disabled in the kernel so I don't have to worry about it ever turning on.

quick way to toggle LTE?

Hey all --
Is there an easy to way to toggle LTE? II'd like to have a quick option to choose LTE but not to leave it on all of the time since my battery dies like 3x as fast.
I know there's the menu option that is like four menus in and requires a reboot.
SETTINGS --> MORE SETTINGS --> MOBILE NETWORKS --> NETWORK MODE
I'm hoping there's a better way.
Thanks!

I'm sure someone will eventually add it to our toggles

As tdwp16 mentioned hopefully someone will add the toggle in. As of right now there is no easy way. That appears to be the ONLY way at the moment

I will have to give that a shot. I have it installed on my SGS3 which is still unrooted at the moment. It at least has not Force Closed on me (like some of the reviewers complained about), but I have yet to find 4G. This is probably just do to the northern part of my area where I live missing coverage in quite a few spots.

I've decided to give this a shot. However, LTE is not available in my area so I will have no idea if it even works....

i'll give it a shot and report back. thanks for the suggestion!

I have every reason that it can be accomplished natively through the settings menu.
Because, if you dial ##3282# and you go through the menus (i forgot the exact one), but it allows you to switch between different modes, LTE being one of them, on the fly without the need to reboot. So I guess all I have to do is remove the reboot option from settings and it should switch the same way that it does in the ##3282# menu.

The app noted in this thread worked for me as far as taking me to the settings but it doesnt work like a toggle does. That being said there is no LTE here in Phoenix yet so I'm screwed either way LOL We have some regular spots of 4g but I dont believe this phone works on regular 4g, unless I'm wrong??? Anyone know?

Yea, I am having the same issue in the northern part of Dallas. LTE is not very good here yet either for Sprint, but hopefully if they sell enough phones and get enough complaints they will break out more towers faster.
Actually I have since uninstalled the App and since then I have not been able to locate LTE at all. I tried putting it back on in an area that I had previously attained 4G and still no go. I hope that Switch It did not mess with my antenna or some such. Just wanted to put the warning out there.

I don't have the SGSIII yet, since Sprint has not launched yet in my area, but I had a couple of questions.
Sounds like you are pretty knowledgeable, thanks for the info. When looking at the phone, I was surprised to see and didn't know the reason for the reboot when turning on LTE. Do you know the reason for the reboot? Is it anything logical or necessary?
I would hope that this will be something Dev's start building into their roms, unless of course there is a legitimate reason for the reboot.
Thanks!

The problem with that method -- which also requires your MSL code -- is that if you use it to select LTE, it forces the handset to LTE only without 1x or EVDO. They are mutually exclusive.
This can be used to bypass the normal settings that automatically upshift and downshift between LTE and CDMA data as a threshold function of signal strength, to force LTE. But it has the side effect of killing the voice/text connectivity.

Where did my 4G go!

I live in area that does not have 4 g so it stays off, however today at airport I tried and no 4G toggle anywhere! Where did it go, I swore when I got s3 I tested 4G but now it's gone? Thanks for help.

GS3 doent have a 4g "toggle" as you say...but you can make sure its enabled
settings-->more settings-->Mobile Network-->Network mode.
Preferred network mode should be set to "CDMA/LTE/EVDO"
If you have "CDMA/LTE/EVDO" enabled, anytime your in a Sprint LTE area your phone icon will switch from 3g to 4g.

it shouldnt chew up ure bttery at all, as all it does is search the network for 4gLTE and if it doesnt find it, it will automaticly go to sleep and try again like 2 or 3 hours later or periodically as it tells u. .however u do need to have sprint automatic connention left on in order for that work. atleast thats what i got from reading the sprint connection optimizer information it gave me.

The optimizer isn't for the LTE. I hate that garbage so I always leave it off. As long as your preferred network is set as stated above, it will automatically switch between them. Side note though, it may switch back to 3g if you don't have a very strong 4 g signal. It likes to be weird.

Sounds like your thinking of a wimax phone. I I had a Motorola Photon and you had to physically turn 4g on and off on it.... I think most wimax 4g phones are that way.

Do any of the custom ROMS have a toggle for 4g/3g? I live in a 4g area but sometimes the signal isn't strong enough so it goes to 3g. Quite annoying. It would be great to toggle 3g off and force 4g.

So I had s2 before s3, so I assume the s2 was a 4 -g wimax? It had a toggle widget.

Have you tried updating to the new radio? I believe they boosted the power to give slightly better LTE connectivity in those kinds of environments.

There is a way to force LTE on the GS3. I did it with mine so that I could map out the LTE zones with sensorly a bit easier while I was driving over the weekend. The way I was able to do this is you need to have Nova Launcher downloaded and installed.
Once you do this, long press on the home screen and go to "Shortcuts".
Next click on "Activities"
Next scroll down to "IOTHiddenMenu"
Then scroll down and click on "IOTHiddenMenu : HDR1X_Selection"
Doing this will allow you to force LTE only mode. Keep in mind you WILL NOT be able to make any phone calls while doing this. For some reason the GS3 requires the phone to be in LTE + CDMA + EVDO Mode to make calls even if you have a very strong LTE signal.
Another app I would recommend downloading is called OpenSignalMaps. Once you have the LTE only mode turned on or even the normal LTE + CDMA mode, you can use this app to refresh your network by clicking the little refresh button at the bottom left of the app in the Overview tab. What this does is pretty much turn your phones mobile networks on and off and then scan for LTE first before scanning for EVDO. I have been able to connect to many more LTE sites by doing this. Even ones that are fairly far away.
Hope this all helps. Let me know if you have any extra questions.

No data connection at all
I have the settings on GSM/HSPA/LTE, but lost data connection completely. Tried to restart and turned on/off flight mode - still no data. Voice in and out is OK. I finally managed to reconnect by repeating the process. Is there a better way to reconnect?
