[Q] International roaming issue on Valhalla rom? - Samsung Galaxy S (4G Model)

I'm on a trip overseas and I'm having issues with international roaming on the newest Valhalla rom. Initially, my phone will register to the network just fine with data and everything. After a random amount of time - anywhere from 5 minutes to a few hours - I will be disconnected from the network entirely and have to reset in order to connect to data, send texts, or make phone calls. There are two networks I can use here in Malaysia and I'm experiencing the same issue with both in multiple cities. Is this a common problem with flashed roms? I haven't ever had an issue like this with international roaming until I flashed this one.
Note: I took a look at the "T-mobile service issue" post and I haven't had any issues staying connected to the T-mobile network while in the states.

I tried updating the modem to KJ1 and I'm still having the same problem. I usually get kicked off the network within 5 minutes and have to search for a network again. Any ideas?

I've not done any international roaming but if the problem seems centralized to that particular ROM, maybe you can try a factory data reset & re-flash that ROM? Otherwise I'd consider going back to a stock ROM & see if the problem is there. If not, then maybe re-flash Valhalla? I wish I had more to offer but I have no experience with international roaming.
Maybe PM WhitehawkX to see if he has any insight?

Yeah I haven't had any issues with international roaming up until using Valhalla. I just tried flashing the KJ3 modem and I'm still getting the same result. I'll probably wait to flash another rom until i get back stateside but I'll PM WhitehawkX in the meantime. Thanks

Good luck. I feel bad for you being in another country and having issues. Maybe try the KJ5 modem; fresh off of the press today

Yeah it's not an ideal situation, that's for sure. I tried flashing KJ5 and I'm having the same issue.

So after a lot of digging with no real results I think it might be a Samsung galaxy issue with roaming on gingerbread? I read a support article from Sasktel in Canada with regards to the Galaxy Vibrant: http://support.sasktel.com/app/answers/detail/a_id/12517/~/samsung-galaxy-s-vibrant-roaming-issues-after-upgrading-to-android-2.3.3%3A
Basically it says there is an issue with roaming outside of the US and Canada directly related to the Gingerbread upgrade for that variant. I'm thinking that the problem might also affect the S 4G variant and that's why I'm having problems. Supposedly this is going to be fixed in future updates and maybe this is one of the reasons Samsung hasn't released an official Gingerbread update for this phone. I realize this is not likely, but is anyone up to the task of figuring out the problem and fixing it before Samsung does?

Can't connect to data network

Currently a Rogers customer running Firefly 2.8 with Speedmod k13e and I've been having issues with the data network all day.
This morning, I wasn't able to send/receive txts/calls. Switched my SIM to my old phone (sony ericsson) and it worked fine, so I flashed to 2.2 and again it worked fine. So I flashed back to 2.8 with speedmod and now I can't connect to the data network. Anyone know what's up with my phone?

What modem does the speedmod kernel use? It could be that the modem they use isn't compatible with your area or possibly you need to change bands. Easy fix to flash another one. Find the modem that works best in your area, download it, install it via CWM.
I flashed to the new ROM and Kernel when they were both released and had no problems, it just randomly stopped sending txts, however I just got confirmation this morning that apparently they all sent today at around 3am so it looks like it's my service provider and not my phone..
Anyway, would the modems work in Canada on the Rogers network or do I have to have specific ones?

If you want something that works pretty much all the time, use JK4 - it's basic and very stable.
It's the one that comes with Team Phoenix's ROMs and I never had any problem with it.
If that's the one you're using, then go ahead and try another one but it can be a problem with Rogers too. I had that problem with my old phone but it wasn't a problem with the phone, it was Rogers.
I suggest that if you don't have JK4 atm and that you like your modem, to just continue using it for a few days and see if it happens again. If that's the case, then change to JK4 (Or any other modem if you're using JK4).
I checked the settings and it turns out I am using JK4, I would imagine it's the same one I've been using because I flashed to Firefly about 2-3 weeks after I got my phone (started out at version 1.0.5 or something).
So the problem would most likely be with Rogers? Considering I've called in 4 times about it, I'm sure they'd be willing to replace my phone if need be.

I'm guessing your phone or maybe sim card? but if you sim is new with your phone than I doubt that's what it is.
You can try a different modem for a few days and see how it goes before returning it. Also if you return it, don't forget to bring it to stock lol
Dude, watch the language and this should have been posted in the correct ROM sticky in Q&A.
That's correct, please post in the correct section.

Q: I don't have data anymore

So I recently bought the girlfriend a Samsung Galaxy S 4g. Definitely a bit different than the Evo in terms of the overall process. It didn't help that I started out in the Vibrant forums somehow...
Anyway. As it stands right now I have her phone all rooted and it has CWM and I'm using the Valhalla ROM. The issue is that she doesn't have data.... and when I go into wireless networks and check out the mobile networks and such, I can never actually see T-Mobile. If I search I can see AT&T, which I connect to and I start roaming. If I do this I still don't actually have internet. I can't use the market, or the web browser or facebook or anything that requires data. The browser will sometimes redirect me to some web2go website, otherwise it just times out or says it can't connect to the server.
So does anybody know what's going on? Please let me know if you need any more details.
I've never had trouble like this between my Evo, or my Epic 4g Touch or any friends phones. I've also tried going back to 100% stock unrooted GB and I still have the exact same problem. The ROM doesn't seem to matter, neither does being rooted.
Since you are running Valhalla bring down the notification bar and make sure you have the data toggle on.
Yep, it's definitely toggled to on. I even cycle airplane mode and make sure it's on afterwards.
Only other thing I would suggest is a factory reset. The phone should be picking up the T-mobile network without any problems. But if rooted or not and on stock vs custom rom the issue remains you may just have to set it back to stock and send it in for replacement.
And I know this is a silly question but make sure you call T-mobile and verify that this line has data plan. It has happened in the past when I added a line that it wasn't provisioned correctly and out of the blue the data stopped working. The service was automatically removed due to a reps mistake.
Check your APN settings. Should be T-Mobile's, if not then that's what causing the issue. Just look up for those on google.

My APN settings are correct. I've now tried several other APN settings though, and this hasn't helped.
I know this phone is on a data plan. It's on the $50.00 a month prepaid. It did work when we got it, and after it was rooted. I just noticed recently that it stopped working, and I'm not sure at what point it happened, and if it has anything to do with what I've done.
I called tmobile and they said they couldn't see any network related issues going on. Just my phone not connecting, so it was made a ticket for the engineers I guess haha. They are supposed to work on it, and they usually will either fix it and never contact you, or call you if they need you to do something.
Bump.
I've been in really good service areas with full bars T-Mobile and I still don't have internet. So I really don't know what's up. The "T-Mobile engineers" haven't called me back or fixed anything yet.
I'm about to bring myself back to stock and bring it in to a store.
Bring it back to stock & maybe put it in recovery mode & wipe caches & do factory reset again. See if that helps before returning it.

You might try reflashing the ROM or maybe just flash a different modem. I had issues like that once when i was on black ice. If you had data before, there probably isn't anything wrong with your phone.

Having the same Data problem
I had an unlocked ATT BB Curve on T-Mobile and the data was working (although very slow...)
I decided to try out a "Vibrant" hoping to be able to install ICS via Cyanablahblah.
Searching on Ebay I bought one only it turned out to be the 4G (it didn't realize there was a difference.)
Since then I can't get DATA on the 4G except in WiFi.
On the network it goes to the page: u.web2go.com and says my data plan does not work on this device.
Has anybody had any success with this problem ?
Could it be a 4G issue ? Before DATA came from Edge.
Have you checked what your APN settings should be with the magics of Google?

tmob probably caught on that you're using a "4G" phone and will try to force you to upgrade your plan.

Is there any way to fool it with a 3G modem flash or something ?
I think I screwed up when I bought the phone not realizing there were 2 variants of the "Vibrant."
I wonder if I would have this problem with the earlier (non "V") 3g phone.
Probably. If it were just the 3G/4G causing the problem, you can force the SGS4G to only use 2G networks in the data settings... but if it's anything like the old Verizon bits with tethering and other data, they check for specific data strings that are harder to fake... I mean, set.

Signal Roaming?

I have a rooted Tmobile phone (Octane) and loving it. This isn't a 'root' question, but a signal issue that I noticed before and after the root (not related to rooting).
Anyhow, when I leave an area (in my vehicle) that has low Tmobile signal, it switches to ATT and says "no service". That's fine, but what I noticed is when I return to the same area, it will take an additional 4-5 miles of driving into a strong Tmobile signal area before it pick up the Tmobile signal.
In my area, there are no agreements to roam on ATT's network, so my phone is dead until I re-enter Tmobile signal area.
My question is, it is a nuisance that my phone can't use Tmobile towers as a priority. It seems to hold onto ATT's towers longer than it should. What can I do to fix this issue if possible?
Thanks in advance!
Edit: My wife has the same phone and it does the same thing.
Have you changed modems? That seems to fix many issues pwople have with connection issues.
Not sure to be honest. I used this process to install Octane's ROM:
http://forum.xda-developers.com/showthread.php?t=1223765
I did see something in Odin about "Modem" but don't know if that is the proper way to install a modem or not.
This thread will tell you how to change the modem.
http://forum.xda-developers.com/showthread.php?t=1192436
FB also recommends one in that thread iirc. But other members have better luck with different ones. Im told it depends on your location but nobody has said which modem is better in what part of the country.
Awsome, thanks for the leg work on finding that for me! Is there a way where I could opt out of roaming so my phone uses Tmobile as a priority 'all' the time?
This is just incase the modem doesn't seem to help. Just one idea I had.
Also, KJ6 modem is the one I need correct?
Not sure of the roaming opt out.
FB puts the KG4 modem is his personal build of VB. Im using KG4. I would try all of the GB modems to see the results.

Poor cell phone reception with new ROMs

Does anyone here have issues with poor cell phone reception after installing new roms? I have a Razr HD XT926 4.4.2 running a unlocked but stock rom because everytime I go to another rom (I have tried 10+ different roms) I end up getting poor cell phone reception. In my apartment I typically get 2-3 bars on verizon but with new roms I get 0-1 bars and when I am outside I never get more than 2 when I normally get 4+. This is preventing me from using any rom because I absolutely cannot be without reception for work.
All roms install just fine but just this issue. Anyone else have this?
Thanks

Hey! So, I came here to try and find some help on this issue or post myself if nothing else. I also have an XT926 4.4.2 with unlocked bootloader on stock rom. I have tried many different roms and personally I love PacRom, but no matter what rom besides stock that I use, I can not get Mobile Data. I haven't checked the cell reception, but the mobile data does not work at all until I wipe and go back to stock. It's really frustrating because I would love to use a different rom other than stock. I do have xposed running on stock, but it can not give me everything a custom rom can. If anyone knows a fix to this, please let us know!

Yes going into that screen. Idk if there is a difference between Verizon account types, but i know for me over on the AHD and on ATT, I need to be set to ATT phone b/c i'm on a prepaid account to get data to work instead of ATT LTE

yes, not as extreme as you, but from what I've read along the way its common to all AOSP roms. My battery life is noticeably worse because its searching for signal.

Hmm... I am on stock at the moment, but I will go to a custom rom for a bit again probably tomorrow to mess around with the settings again. Either way I will post what I tried and possibly screenshots for maybe more help on my part or to help others if they have the same situation. I just have no idea what needs to be changed. I tried copying the apn settings from stock, but that didn't seem to work. Maybe I did something wrong or missed a step or something. I'll be back tomorrow. Thanks!

[Q] LRX13O T-Mobile Cellular connection issue

I'm with the new Lollipop LRX13O roms.
Somehow, It's getting trouble in connecting T-mobile network. Wi-fi definitely works fine. But, it's struggling to find 2G/3G/LTE and just no bar, or sometime bars with no calls or data.
I already tried resetting APNs, and set the cellular network, but no luck here.
If anyone experiences the same problem, please let me know.
Thanks.
hrm I was afraid that this sort of thing could happen. Ah good old early adoption bugs and whatnot Seems to be a reoccurring theme of late with Android updates and cellular providers. Particularly T-mobile. I know it may seem like a dumb question but have you tried it in different areas ie different towers? how about reboot?
I'm on T-Mobile and I'm doing okay. You could try flashing a different radio and see if it works.
Should add I'll be updating mine as well. Currently on T-Mobile $30 plan. Just have to figure the best method forward yet. Most importantly is getting a good backup image(currently stock with locked bootloader).

Hopefully, this is just a problem only for me. I rebooted multiple times, and actually tried another Stock 5.0 rom, but having the same issue.
For last a couple of days, I didn't have a chance to go out from home, so didn't check from other areas, but tried different places near home though. And weirdly, my wife's Galaxy Note 3 has no problem at all in both call and data.

I re-flashed the LPX13D the Preview Radio, I believe that is the most recent radio. But still no luck. I'm kinda hesitating to flash the KK radio, maybe I should try it anyways.

Yeah I know how that goes. Its kind of amazing that these devices work as well as they do. There's so many things that can cause glitches. Best of luck to you!
Anyways about to take the same plunge myself and upgrade. Most likely going the factory fresh route since its a major revision. A chance to unlock my boot loader anyways. I'm sure however something will break, be incompatible, etc. Right now I'm most nervous about the hotspot functionality with T-mobile still working. On the $30 prepaid plan and with KitKat I had to disable IPv6 otherwise I always got the upsell page before I could use it. Even though I don't tether often its nice to have.
flashed a factory stock 5.0 zip yesterday. Came from Slimroms 8. Flash rom,new radio,elemental kernel and super su zip in that order. No problems with anything here. No connectivity issues, no /sdcard issues, no battery drain issues, nothing.
