Signal Roaming? - Samsung Galaxy S (4G Model)

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.

HTC Touch Pro/AT&T Fuze with Fido

Hey everyone,
I got an AT&T Fuze (Touch Pro) and Im using it on Fido in Canada. My data is working perfectly fine, my only issue is that my phone keeps switching from 3G to H every once in a while, I was just wondering why and whats the reason for that?
Also, I have a little exclamation mark (in a yellow triangle) in the top right hand corner right beside the 3G/H/E Icon. I don't know why thats there?
Thanks to all for the help!
No, that's neither yours nor your phone issues. Once you' re in the better speed coverage, the phone will jump to H or your phone is accessing the internet.
"little exclamation mark" is a "roaming" indicator.
Heres the thing, it jumps back and forth while even accessing/using data.
Is there anyway to get rid of the exclamation mark?
have you flashed the rom?
I would be interested in how to get rid of the roaming icon too.
I have tried all the registry changes to no avail. The icon, and roaming warnings for things like the weather app, remain. It's about the last thing I need to fix but I seem to be stuck.
Im using RRE's ROM. So far it seems to have fixed itself, but now Im having more issues. I wonder if I should flash to a different ROM.
Hi guys,
I have a somewhat related problem and I hope someone can help me out. I just recently bought an unlocked HTC Touch Pro (not the Fuze version) and I am using it with my Fido sim card. Everything works and I was able to setup EDGE on it, but what bothers me is it keeps saying that I am roaming (for example when I access the Weather app). I am wondering if this is just some sort of a glitch due to the phone being unlocked or am I really roaming? I also get that roaming icon at the top. I am located in Vancouver so I am not out of town or anything. I just want to make sure so I don't end up having a crazy invoice by the end of the month. Thanks very much in advance.

It's because Fido uses Roger's towers now, but the companies are still identified separately and therefore it thinks you're roaming. As long as you have a data plan, you should be ok.
PS. Depending where in Vancouver you are, you should be getting at least 3G (3G), or hopefully HSDPA (H), vs Edge (E).

xda_fanboy, thank you very much for the helpful information. I can finally stop worrying. I do have a data plan with Fido so that should do. However, this is the second day of using the Touch Pro and the only data network I get is Edge. The only setup I did to my phone is what is listed in http://www.iday.ca/2008/11/how-to-setup-rogers-or-fido.html, under the Fido section. Would you mind taking a look and see if that is all that I need to do? I really appreciate all your help. Thanks again.

I also have this phone and live in Vancouver on Fido. I don't think it will work on 3G, or so it seems. Mine is not the ATT version either, just the stock HTC. Currently it runs fine on the standard network, although as mentioned i have not been able to get rid of the roaming icon, but have never been charged extra. Its too bad we can't use it on 3G, and if any can find a way, that would be awesome, id love to be using the full potential of this phone.
I think we are stuck with no 3G, unless there are any suggestions?
If your not using the AT&T Fuze, then you won't have 3G in North America. Don't worry about the roaming icon. Since the phone (or is it the software?) has no idea that Fido uses Rogers' towers, it thinks your roaming. I have the roaming icon as well, had it on many non-branded Fido phones.
I turned off 3G because I hate seeing my icon go to 3G then H at random times besides when Im using actual data and it seems that with 3G, I get worse reception! Makes no sense I know, I've tried 3 different radio's and all have the same issue. Im thinking if an HTC Touch Diamond Rogers branded Radio will work, then that would probably work the best. Anybody know if/where I can get it?

If you bought a stock HTC Touch Pro (non-ATT, non-North American) then you won't have the NA 3G radio frequency and you're stuck with Edge.
Regarding a ROM, head over to the ROM sub-forum. There's a step-by-step guide on flashing your first ROM. As far as which ROM is best, it depends entirely on what you want from it, and even then varies by personal choice from person to person. There is no 1 "best" ROM. Check out all the ROM threads (there's a Roger's specific ROM available FYI) and pick one based on what you like.

I have a similar problem as Speng2, but I have the HTC Fuze which is the american ATT branded one. I unlocked it, flashed the NATF 4.7 rom and tried many diff radios and can never get more than EDGE. I used to have 3g when it was stock. I live in Los Angeles which is a 3g area. I get full edge signal but no 3g or HSPDA. I have a feeling it has to do with a setting. Pls help.

This thread was specifically for Fido, a Canadian carrier. I have no knowledge of the settings you will require for your carrier in LA, which is the most likely reason you are not getting 3G. I would try contacting them if you haven't already. Otherwise try and find a thread for your carrier, or perhaps check HF (not sure if we can post URL's to other sites). Good luck!
What if you dont have a data plan

What if you don't have a data plan? It seems that sypod has not been charged extra for Roaming... Does anyone know how Roaming works with FIDO? I just got the HTC FUZE and I don't want to have to pay outrageous Roaming charges. Any Ideas?

[Q] HSUPA and Data on Captivate Help

I seem to be having an issue with my data and am trying to narrow down the reasons for my problem. The issue is I CANNOT use HSUPA (H) for data, I always get a connection timed out issue. I put the phone in 2G GSM mode only and have data working, but of course I was spoiled with better speed I can't stand it.
My question is if AT&T could be doing upgrades to the towers in my area, will that affect my speeds, or is something broken internally in my phone. When I select WCDMA mode, it takes FOREVER for it to connect and says searching for a long time but does connect or displays (H) with 3/4 bars of signal. My friend has an unrooted captivate on 3G and has no issue with data. Does anyone know the cause of this.
I have tried a few different modems (jl3, jk4, kp1....) all the same and have tried 2 different OS's with same data timed out issues while trying to use (H). I am currently in the process of flashing back to stock to see if that will resolve the issue. Thank you for your time guys.

H doesn't necessary mean HSUPA. It simply means HSPA (HSDPA only or HSDPA and HSUPA). You didn't mention anything about your firmware but I guess you are experiment with non-Captivate firmware and modem combination trying to get HDUPA working. From what you described, it seems your current firmware and modem combinations lacks 850MHz support for 3G (most European firmwares lacks 850Mhz) and your local tower happens to use 850MHz, not 1900Mhz. Just a guess.
Make sure you have the modern set to proper frequency (WCDMA 850 or 1900) for your area. The modem thread can tell you all about how to do it.

Sorry guys, I guess that was an important part I forgot. I was running Andromeda and thought the same so tried Cognition 4.1.1. Also after going to stock 2.1 I still have the data issue. I can connect to wifi just fine, but no using ATT data will work.
I called customer service and walked through the steps as usual and after some looking into my area, he said there were 3 towers reporting severely degraded. It just sucks seeing my friends phones working with no issues. He said that repairs are stated to be finished sometime in the next few days and to call back later in the week if the problem persists.
Looks like you tried both i897ROM and non-i897 ROM, so it's not firmware related.
Did you try to put someone else's SIM into ur captivate? How about some other devices in ur area?

I didn't think about trying my friends sim card. I will test tomorrow morning. Ty for the idea to isolate the problem to my phone!
umm not really related to your phone. but im suggesting its the tower upgrades getting them ready for 4G that is causing your phone to act up. i have a HD2 and we have 3G down here. but since early march i get nothing but EDGE. what happens in the month march? AT&T will be launching 4G in selected markets. it was confirmed once i was talking to a AT&T tech. so im just waiting to see what happens in the end of this month.
NOTE: it could also be your sim card having problems. AT&T replaced mine thinking it was a problem with the sim card since i have a AT&T native W350 and i was getting the same problems. call them up again and ask to talk to a tech and tell them your having a problem with your sim card. they will set you up a appointment at a corporate store. free of charge.

Sorry for nor replying sooner. My 3G data seems to be working again. My lack of in depth knowledge is why I put the hsupa above when my phone displayed H I didn't know what to call it.
It must have been tower upgrades. I didn't restart my phone and left it on the charger overnight and the next morning I had no issues. I did a reboot of the phone as a test and connected with data with no issue. Too bad as I was close to getting a replacement, though it would suck and be my luck to get one with other issues. Mine is a 1007 and works perfect (other than the obvious GPS.)

[Q] Baseband (modem) questions

After much reading, and stumbling over the same posts repeatedly, I must ask for help.
Heres the phone:
Gt-i9100
2.3.6
i9100NEKF2
2.6.35.7-i9100XWKK5-CL754841 [email protected] #2
Checkrom RevoHD V4
CriskeloROM Gingerbreak v32
Currently have a Optus sim loaded into it, staying in Melbourne Australia.
Optus seems to be lousy, I've talked to several people who seem to agree. Since public perception is far from accurate, I cant really blame optus entirely. I havent tried any other SIM cards yet since I need the optus number at the moment.
I've tried quite a few ROMS and quite a few different Kernels, not being able to tell much of a difference in signal strength. The phone will have the 3g icon lit up, but refuse to do almost any activity. Then five minutes later in the same location it is working perfectly, with a ping of 147ms and download rate of 327.7kB/s (using Speedtest.net)
Since I am using KitchenPro I am able to change the modem easily, some dont work, others do. How do I narrow down which ones are best for the phone? The answer of "use it for a little while and you'll know" cant be the best answer. Is the carrier-shipped modem the best that is available? I've read the modem ref guide and it doesnt offer anything other than a list of letters and numbers. Some people have reported things working well with telstra on particular modems, but nothing on Optus.
1) Is a baseband or modem something that will either work, or not work? Or there a signal difference from one to the next.
2) I almost always have 3+ bars of connectivity for the cell service, it works fine, all the time, even with the modems that did not allow data connectivity the phone always seems to work. Does a modem package effect both cell service and data?
3) What would be the most effective method of testing a new modem?
4) Is there a guide somewhere that lists the guts behind the modem packages, ie frequency ranges, so that I can look up the carrier, and match it manually with a modem?
Please Help! With spotty services available, and no means of telling if my problems are carrier related or phone software issues, I find this quite frustrating.
Thanks for reading

[Q] 4g data drops often...too often

i have to reboot in order for the 4g data to work again but it only stays on for about a minute and then it stops working again. everything else on the phone works ( text, voice, wifi etc...) I read somewhere that flashing different radios might fix it but im not sure about that. anyone else experience this and have a work around? i am currently on baseband i535VRLG1
Thanks In advance
i called Verizon and they said it may be the sim card thats damaged. if that were the case wouldnt voice and text fail as well?

I'm having the same issues recently. I've always gotten a 4G signal at my house (albeit not the strongest one) but lately, my phone will not hold on to the connection. When coming off of wifi, my phone will not acquire a data connection at all most of the time. I can still send/receive texts and calls but there is no 4G or 3G icon, no MMS, and no data. I have to toggle the radios on/off, or change from CDMA/LTE to Global (or GSM) and back, put in airplane mode, or restart.....there is no guarantee any one of those steps will work. Sometimes I have to do it repeatedly until I get my data connection back but it is only temporary.
I'm on the i535VRBMF1 baseband and updated to the ML1 modem to try and resolve but to no avail. I have replaced my sim card (as I initially though that was the issue) but it has not helped either.
The only thing I can think of is that my PRL may have been updated (it is currently 15310) and it's causing issues with the towers in my area.
I just got back from Hawaii and was also in San Diego for a few days and had absolutely no issues. It seems to only be an issue now when I'm at my house which makes me think it is something VZW network related and nothing to do with my phone per say. It's really driving me nuts though.
BTW, I'm in Southern California (Irvine).
I seemed to have fixed the issue by reverting the baseband back to vrlf2. I had to switch from global to 4g/LTE because I vegan to inch roaming charges lol. Verizon credited me and no dropped 4g signal. So I'm happy.

What ROM are you running? I'm just curious what the implications are of running an older baseband (from the ICS days) on a newer ROM/Kernel.
I'm running cleanrom8.1 core edition. Slightly buggy but tolerable.
I was finally able to somewhat resolve my issue so I thought I'd post in case anyone else is experiencing something similar.
By using a few different apps and testing techniques, I was finally able to deduce that my issue had to do with EHRDP hand-off with the towers in the immediate vinicity to my house. I'm not sure what VZW did to them lately but it doesn't appear to be a problem in other locations so it seems like the issue is on their end (and not something to do with my phone).
In any case, it seems that when my 4G connection is weak and EHRDP is detected, it is dropping the connection entirely instead of handing if off to 3G (EVDO). The connection is also never transferred back when a 4G signal is detected either until I reset the connection where there is a moderate 4G signal.
Again, this only seems to be an issue when connected to the towers near my house and doesn't occur when traveling abroad.
To fix this, I have disabled EHRDP by doing the following:
1) Open the dialer and type *#97328640#
2) Select "[2] CDMA"
3) Select "[2] Data"
4) Select "[7] eHRPD e/disable"
5) Select "[2] Disable(*)"
6) Reboot the phone
Now my phone switches between EVDO revA. for 3G (using the native protocols) and LTE rather than relying on the broken eHRDP protocols. This workaround will have to suffice until VZW fixes stuff in my area but at least I don't miss MMS messages anymore.
Hope this helps anyone running into similar situations.

[Q] Galaxy S3 I535 No Service After KitKat Flash (4.4.4)

Hello everyone. I was hoping that some of you that are more knowledgeable about this stuff could help me out here. I recently flashed from CM 10.2 to KitKat (4.4.4), which everything went smoothly for the most part. However, I've noticed that my phone constantly has no service. I should probably state that I live in an area with very low service to begin with, but prior to the flash I was able to get at least a bar inside my house. Now, I'm unable to get anything.
The first thing I could think of to check was my settings in the phone. The data is enabled, CDMA Roaming mode is set to automatic, CDMA subscription is set to RUIM / SIM, and the Preferred Network Type was Global. I wasn't familiar with the global setting as I was used to seeing the LTE / CDMA / EvDo options there. So, when I clicked on it, it now gives LTE, 3g, 2g, 1x, and Global as options. I tried changing it to 3g, but the changes would not save that way. The only way I could get them to save was to power off the phone, take the sim card out and put it back in, and then reboot and switch them. Once i pick a new setting (which is now set on 3g), it locks it and I can't change it again without removing sim card.
When I look in About Phone > Status section, I'm seeing the network says searching for service. The mobile network type is unknown. The service state is out of service, and the mobile network state is disconnected.
Is there anything I can do to fix this issue? If so, I would truly appreciate any type of guidance you guys or gals could give me. Thanks!
I didn't read your entire post but myself and several others have reported signal issues after 4.4.4 flashes on all different ROM types. I think 4.4.4 is just picky about what firmware and baseband you're running. I flashed a few different RPM packages too but in the end I got lucky flashing the BLK3 modem and it seemed to fix my issues. I had noticeably poor signal strength most of the time and a couple times I would look down at my phone and I'd have no signal at all.
Maybe a dev or expert can shed some light on the root of the issue. I don't know enough about under the hood stuff to make an expert diagnosis.
Edit: The unanimous fix that everyone appears to agree on is to flash the MF1 AIO (all in one) package and then flash the ML1 modem only. Problem is finding a legit source for the MF1 aio package seems to be up in the air.
Like I said though, I didn't even do this. I was just trying all kinds of combinations of modems/aio's/ and rpm's and I got lucky. 2 days now with a solid signal at all times. LTE speeds are blazing too, 45 down and 10 up.
Check ur imei number. Or flash a backup and see if that fixes ur problem.
