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?
Just got my Edge and switched over from S5. Now my signal just randomly drops. Tried everything, update profile, change sim, reactivate, change roaming to home only, even went to the store. Maybe someone has a fix or the same problem before I try to get it exchange..
I am suffering through the same problem.
Ill have lte for a while and then i lose the signal completely. I had the galaxy 3 and it worked on lte just fine. Methinks the lte antenna doesnt work so good. Sometimes if i go to airplane mode and come back that works other times i reboot. Im tired of rebooting. Ive just lost the signal now trying to type this. If i switch to cdma it is much more reliable but who meeds a 1mb download speed. Iay be returning this phone soon. Such a shame. Its such a pretty phone.

What area are you in? S5 and note edge both use spark so it shouldn't be a signal issue. If you're in an area you got coverage in before, it's probably a hardware issue. Put the same SIM in the s5 and see if it works. That'll confirm it. I'm in Atlanta with plenty of lte and I've had no connectivity issues so I know for sure the edge (at least mine) works well.

Like I said, try the SIM in your old s5 if you still have it. If it works fine on there, it's probably a hardware problem with your note. Get it replaced.

Do you actually lose signal or does it just appear to be very weak? You cannot compare to an s3 as the edge runs on the Sprint Spark network. Spark works well with even one bar of signal in most places (I've gotten up to 5Mbps) and with full signal you can get 20Mbps +.
smh!!!
Ok i bought both the nexus 6 and note edge with sprint....got both in hand right now and neither phone will connect to the sprint network....after talking to tech support for a hr i was told to go to the store which im NOT doing bcuz the store reps have no clue and dont even have the phones in the store yet DUh sprint!.....so im assuming phones to new may have to wait weeks for minor software updates...... C'mon
I was having the same issue since I bought the device at the sprint store. I just kept removing and putting back the sim card till it finally stop. Anybody knows what this software update on my notifications brings?

Well, i live in goldsboro, nc. We dont have the spark network here yet that i know of. We do have 4g lte which always worked fine on my g3. On this phone it seems like i lose the signal a lot ie. Searching for service, webpage not available, sms will send when you regain service. I very rarely get more than one bar signal strength, then the lte turns light grey, then i lose signal. I can usually get it back by restarting the phone or going onto airplane mode briefly and then coming back. Ill have the signal for a few minutes and then lose it again. It was really bad last night but it doesnt seem so bad tonight. I got the phone tuesday so tomorrow is my last day for carefree return. Im not sure what to do. Has anyone else noticed this?
Thanks in advance,
Billy

In many, more developed areas, spark will work fine even with 1 bar. In some areas though, you may get connectivity issues due to this. I believe you can call customer support and they can switch you over to LTE if you wish (this will also give you back the ability to use internet while on a call). At least the guy I talked to offered it.
me too
so I have had my Sprint Edge for one day. The signal fluxuates constantly and the data works maybe 20% of the time. Called sprint and working on a replacement as we speak. Went into the store and there was a repair tech there saying he has seen 5 other Edges with same issue and thinks its not the phone but the network profiles and that sprint will release and OTA to fix it. But am returning mine for exchange just to rule out hardware issues
I ended up getting hit with it again but after installing the software update no more signal issues. Funny thing though is I cant find any info on it and it seems I'm the only person who received it.

It seems like i only have this problem at night. Theough the day everything ssems to work but with a low signal. I suspect sprint is doing something to the network late at night and thats why im having this problem.

had the note edge for a day and im having the exact same problem regardless of day or night.. the signal intermittently drops from full to zero bar with red X by it. when there is signal, it is very fast but it just doesn't stay on. i also have a note 3 right now and never have issues with losing signal at work or home. also called tech support and performed update profile/prl/change roaming to home only routine but still losing signal. tech support telling me to take it to a sprint store for an exchange but i don't think it's the phone. any information on that software update RayTrue04? im also from atlanta.

I have no idea what it brought to the table but my issue has been resolved. I only lost signal once right after the update was completed but then it's like something just settled in and no a hiccup so far. *fingers crossed*

Popped up on its own. My friend got the update too but he's still experiencing the signal loss so now I'm not sure what did it for me. The only thing else I recall doing is switching lte/cdma mode to automatic and turning on all the roaming options plus the roaming guards.

tried that on mine with customer service on the phone. Still having issue and am curentyl waiting on a replacement phone.
Its a Firmware issue
Guys I am almost positive this issue is due to a glitch in Samsungs firmware. I tested the data and was able to download over 1 megabyte per second with only one bar on 4g Spark LTE.
According to the tech support person I talked to that would not be possible on only 1 bar. (btw I stopped the test after hitting 1 Megabyte per second for those that need help converting that equals 8mbps). I was in a saturated 4g Spark network with 5 towers within spitting distance from my location and it still only showed 1 bar. I'm thinking either how the tower reads the signal strength or a bad code line shows no more then 1 bar no matter what.
Now for those having dropped data. Check the Sprint site to see the saturation for 4g Spark service, the phones are now setup to LOCK on and HOLD onto the FASTEST tower, which according to the tech who also filled me in on the way the new antennas work, can lead to what seems to be dropped service. She would recommend for individuals having this issue if Spark service is not fully activated in your area to switch over to CDMA only under settings to fix the LTE data dropping issue. BTW the Spark LTE service is apparently different then the old LTE service so those versions do not appear to work interchangeably (according to the Sprint service map).
I also noticed someone else got the new version of the firmware, which I also have and that did NOT fix anything for me. If anyone is struggling with this issue I would wait until the firmware is updated again. WHICH I hope by that point we can get flashable firmware for those of us that are rooted...???
Now for a VERY Important Fact: there will now be no way to use data while on a phone call. These phones are a single antenna model. You can either be on the phone or data... UNLESS you are making a WiFi call. That is why this is now a option. It will keep the antenna set to the data side of things and make it possible to use data for the internet at the same time.
I hope this helps.

I am on my 3rd S6 now in 3 weeks due to rubbish reception. Im lucky to have 1 bar (-113 db) of 4g signal in my town which has full 4g coverage. If I put the sim card into my G3 or M8 I instantly get full 4g coverage (approx -80 db). Now this is clearly a widespread issue as a quick search of google brings up people all over the world on EE, Vodafone, Virgin, AT&T and sprint to name a few. Just wondering if anyone else has this issue. Im convinced its an issue that can be sorted with a software update to the modem but then who knows lol.
I got G920i model and I am using it in Canada. For me, the network is constantly fluctuating and it is stuck at -99db =\. I thought it could be hardware, but it is widespread. I am gonna get Canadian Galaxy S6 version to test this. If that has same problem, then its all S6 variants.
I hope its software because I love this international model and it has AWS (B4) that works on my carrier!
I am on latest 5.0.2 BOF6 (June 20 build). Has this network reception problem fixed in 5.1.1???
No I updated the modem first on mine to the 5.1.1 modem and it made absolutely no difference. The updated the whole rom but again no difference. Im with you in hoping it can be sorted with a software tweak to the modem. Maybe by increasing the tx power of it. But its certainly widespread so just need samsung to take note and do something about it.
Hmm...might be an antennae hardware issue. Bring back your S6 to Samsung for warranty check...
This is my 3rd one now with the same problem. The odds of 3 handsets having the same fault are pretty big. Coupled to the fact there are hundreds of people with the same problem. I know that on the old s4 and a few other phones there were apps to actually increase the tx power of the on board radio. Im convinced its just a snag that can be sorted with a software tweak.
Hey everyone,
I've never really been into the whole flashing deal and I'm also pretty new to the xda-forums so pls don't hurt! :angel:
Anyway, so live in Germany and imported myself an S6 Dual Sim Version via Amazon, so that I could have Internet both there and at home in Ausria at all times. It had a Russian Baseband and CSC but it worked and filthy casual that I am I really didn't mind until now. It's a really weird issue, so sorry that the post turned out pretty long. I haven't found any similar common 6.0.1 Bugs, however I'm not even completely sure if it really is a problem of the updated OS anymore...
So here's the deal.
In Germany I got the prompt to update to Marshmellow 6.0.1 via OTA. Having heard mostly good things about it I downloaded it without really bothering too much about informing myself about any known issues with 6.0.x . After downloading it in Germany my Signal and Mobile Internet worked fine, however I did experience some battery drain in the following days and decided to initialise my phone via Samsung Smart Switch, as I had done with 5.1.1 when I first got the phone because it's cpu never went into sleep mode. Worked out fine then.
Well ever since I did the same thing with my S6 with 6.0.1 the whole dilemma started. Regularly, my phone will show 4G Signal Reception and even full bars, but I am not able to load a webpage or even be called by phone. Wifi works fine, when I have these outages. When I activate flymode and deactivate it again, my reception works again for a couple of minutes, however, the issue will return after 5-10 minutes. Usually even faster when I'm in a moving car or train.
When I switch SIM Cards I can be called on both, but I can't seem to connect to my mobile internet on the Austrian card (can't check on the mobile connection from the german card as roaming is locked by the provider). I went to my austrian network provider and had my sim card replaced, no change. I flashed DBT G920FXXU3DPCA Android 6.0.1 via Samsung Updates hoping that the right baseband would fix it - Nope.
Any of you guys have any other ideas? My last resort is flashing back to 5.1.1 stock. Trying to replace it through Amazon will probably be hard, because the KNOX Counter is tripped. It already was before I flashed 6.0.1, but that doesn't really matter to Amazon I guess. Also the bug is way to specific to replicate anyway, so I'd probably receive the same device back and I don't really know how I could prove via screenshot, etc...
If there's anything I can upload that would help, pls tell. Hoping somebody here might have an idea!
Having similar problems but also with wifi. Any advise appreciated

I have the same problem with cellular reception with my S6 duos G920F. My problem is only with sim slot 2 though. It seems to show full bars but when people call me they are getting me as unreachable.
I have the Canadian S8+ ( SM-G955W ). A few weeks ago I got tired of waiting and flashed Oreo, not the beta but what was said to be an early leak of the official release. (Build Number ending in CRA1). It was meant for SM-G955U (which the Canadian version isn't) but I haven't noticed any problems except maybe a little loss in signal and a few features like Caller ID & Spam Protection. I can live with that. But what I'm wondering if there is a better software version I should be on? Maybe one that will automatically get updates?
Here's a screenshot of my software info:
I believe the 955U is up to CRAF now. I ran CRA1 for several days with no issues, then moved up to CRA9.
I'm not sure how the 955U firmware plays with the Canadian radio bands, but if you aren't having any issues, then I'd say it works fine. You could always try some of the newer builds and see how they work.

You can dial *#243203855# from the dialer and change your CSC. That may help with signal issues.

Ok, this firmware is Multi-CSC. Meaning it will read your SIM vatd and change to whichever carrier you have. Your carrier may have disabled those dialer codes. Verizon disables all the dialer codes in their software.
OP, you asked if you were "on the best software?"
Answer: No, I am on the best software.
