My internet data frequently disconnected - AT&T, Rogers, Bell, Telus Samsung Galaxy S III

Hello,
i am back again with a new problem!
All the previous problems that was mentioned in this forum is GONE. i was a happy owner. Until i got this problem.
so i wanted to try new Modem, just so i can increase my Signal, and right now, my data plan is keep going on and off, and most the time i can't get it connected it.
i did the wipe date /factory reset from the ROM manager, and wipe cache and dalvik. and yet the problem is not solved.
right now, am running cm-10.1-20130304-EXPERIMENTAL
and the Modem am currently running which sometimes works ( I747MVLDLK4 ) am with Rogers, Canada, Edmonton, AB
If anyone helped me out with this, your next coffee is on me! for real!

anyone?

When I have Wifi or Signal/Data issues, I just Odin back to stock and then re-root & flash ROM again. Works every time.

Did you use ODIN to flash the stock ROM and factory reset in stock recovery ?

Yes! i think i did a mistake. While i restored to the stock rom, The baseband that i was using it was I747MVLDLK4 and not the STOCK modem. So maybe that is why its not getting connected? am trying to apply the stock modem into the the stock rom, but its giving me Fail error.
am just scratching my head right now to be quite honest and this close to throw my cellphone outside of the balcony.

What type of fail error?
How are you trying to flash it?

i managed to make my modem into the stock version. However am just getting "E" in my data connection. Reminder am still in STOCK ROM and stock modem now. is that a good sign that i slighty getting everything back??
should i just install the CM 10.1 now and see the results or what you guys recommend?

annnnnnnnnd my " E" is gone.. Beautiful
do you guys think it might be a actual physical sim card issue?

UPDATE: i restored my phone into the stock rom by Odin3 and now i just re flashed the Cm 10.1 again. sadly i still have no connection and my income and outcome for calling and texts is also not working.
please help!

Try flashing Task's AOKP and see if you have the same issue. Additionally, try deleting the current APNs (access point names) and manually enter the APN settings for your carrier. Could also just be a faulty SIM card as you mentioned.

[Q] No service whatsoever

*Bad english ahead*
The problem is that my phone seems to refuse to get any service at all. The signal icon just shows a big "X" and it is stuck in "Searching for service".
Phone status shows that the Signal strenght is on -79 dBm, so i guess the anthena is working just fine. But below Service Sate it just shows "Out of service".
Im using a EB13 Modem with the SyndicateROM.
In fact, the phone was working just fine with MidnightROM until i flashed the SyndicateROM over.
Already tried reverting it to Stock rom and nothin, any suggestions?
Did you try reflashing (Just) the modem through ODIN?
Let me try...
Does this one should work? (The odin one)

Did you flash your Epic to Telcel? If so, that process might be causing you some problems. After using Odin to get back to stock, install CWM3 then SRF1.0.1, then once you're stable there, try the carrier flash again.

What do you mean by "Flashing my epic to telcel" and that "Carrier flash?" is on Iusacell, since Telcel dont support CDMA.
And one last thing, what is SFR1.0.1?
EDIT:
Im reverting back to DI18 Stock rom with odin to see if i can do something.

Oh okay - the banner under your username says Telcel, so I figured they were it. I thought I'd read they support CDMA but I was mistaken.
SRF1.0.1 is SyndicateROM Frozen 1.0.1.
On the flash, let me rephrase - did you do anything special to get the Epic to work on Iusacell, or did it work there out of the box?
That's the reason then. You can't change ROMs if you're on a carrier other than Sprint, it will revert your phone back to Sprint.

Nope, the phone was working just fine out of the box. It had signal (Roaming) and all.
I even flashed like 3 roms before Syndicate and it was working just fine. Was just yesterday that i decided to try this ROM out and got the problem.

I'm not entirely sure what to tell you - there's nothing in SRF that should/will/can cause any problems of that sort. Going back to full stock via Odin didn't help?
I followed this guide: http://forum.xda-developers.com/wiki/index.php?title=Samsung_Galaxy_S/SPH-D700 to return to Stock rom, but i can't get this thing working
Im pretty much lost as well.
EDIT:
Oh god what the... I was just messing around with the phone. Turned on the Flight mode. Made a Factory reset via Privacy setting, Rebooted the phone, turned off the a Flight mode and suddenly had signal again.
I dont know what happened, since i tried the factory reset before with no luck... But well, im glad its working now. Thank you to both of you for the help anyways.
I have a similar problem as the OP, and I'm pretty sure it's ClockworkMod that's causing it.
Seems like every other time I do something in CWM, I get no service and an unknown Baseband and Hardware version in the phone's settings.
So far the only reliable way I've found of fixing it is to Odin all the way back to DI18 and start fresh.
For some reason Odining the modem or EB13 doesn't work (I still get no service).
And I must say, it's incredibly frustrating.
I guess I'll just have to get SRF flashed and never touch CWM again (because doing so almost always breaks my phone).
I'd like to be able to make Nandroid backups though, but unfortunately, doing so breaks the modem (which really doesn't make any sense).

Bad signal or No service after flashing

Hi there. My device is a i747 on Virgin Mobile (Bell) in Canada. I have no service, or 1 bar of signal (can't make calls at all).
I flashed CM10 in November. Then just the other day I flashed Synergy. Then switched to Galaxy Mod. (I followed instructions for each flash, wiped everything each time etc. even when not specified in the instructions)
Today I switched to CyanogenMod 10.1, I got stuck in a boot loop. So I reflashed back to a stock root image with Odin (root66.stock_Bell_I747MVLALH1.tar). Now I have no service! I can see one signal bar. Under status it says VIRGIN.
EDIT: Now after I typed that, I reflashed another rooted stock image, I have no service at all and IMEI shows as 0.
EDIT: Since posting I have restored my IMEI, the phone seems to be registered on the network. But still no signal just like before
EDIT: March 16: I have tried flashing modems. Then I restored to the latest actual stock (non-rooted) image from my carrier. Same thing.
Please help me out, thanks

Hello.
I just travelled by train and it picked up signals, both voice and data. Possibly because i was passing close to a cell tower. But it quickly stopped working whenever the train moved too far from a cell tower.
Then back to no signal at all.
Will check APNs, but I don't think it would start working then stop if it were a configuration issue.

I tried about 4-5 so far. Didn't work. It's the same result. I'm not able to make any calls, it either shows 1 bar or No service.
So far I have set APNs, updated IMEI, and reflashed modems. When I get home I'm going to try more stuff.

Hi there, I just flashed this file from Samsung-updates.com using Odin. It is 4.1.1 from my carrier.
KIES_HOME_I747MVLDLK4_I747MOYCDLK4_538866_REV04_user_low_ship.tar.md5
Then I did a factory reset from inside Touchwiz. What should I try next?
I tried flashing another image: KIES_HOME_I747MVLALE8_I747MOYCALE8_20120523.225040_REV04_user_low_ship.tar.md5
and doing the factory reset code *2767*3855#. Didn't work, still have no signal in general.

No phone service

I can not get any radio to work to make or receive calls! I flashed everyone out there and still can not make or receive calls. What method can I use do to get it to work? I flashed radio from TWRP with Factory reset, delvik and cache and then flash with no wipe and I just cant get that or any radio to work. I just get AT&T when I do a scan, which I use T-Mobile. When I choose search in settings in mobile networks, still nothing. When I try to use phone, it always says no network avail. and yes I have data box checked off. It just seams lately any Rom I flash after the newest stock, (JB) I have radio issues, can not make or receive calls. I even erased, wiped everything and started from scratch with stock. Phones works fine, but when I try any ROM, no calls, no matter what radio I flash. I must be doing something wrong. I must say, that I flashed many a Roms before and all worked well until now! I even download same radios in case I got a bad download. I can use kernels, such as Tiberius with Stock JB. I Flash a Rom and no radio, no matter what Rom. My version in stock is UVMC6, SGH T-989 phone. (T-Mobile). I know all phones are different and thought maybe something in stock files I might be able to use, but don't know which files. I am not a dev by any means and thought if I could use the stock I have now can work with the any Rom here. I never dirty flash anything, all Roms work that I flash from sd card, just not able to use phone in any Rom at all! I thought maybe I can manually put in APN, but I have no idea were to get address to enter. I am from Delaware if that matters as far as APN. Can anyone give any suggestions of what they did to get radio to work?

Verify your APN settings are correct. If there isn't a t mobile APN set up than try creating one. Also go to Settings > About Phone > Status and make sure your phone has a valid IMEI number (anything other than 0)

no signal after flashing rom

i have a samsung galaxy s3, ive been rooted for a long time and flashing roms all the time. well i flashed a rom just now and i have no signal, not sure if i burned out the radio (not sure if thats possible, but it also said to insert sim card while it was already inserted), but i dont understand how that would happen. the sim card works in another phone that im using now, so its not the sim card thats causing the issue. my carrier is at&t, and no signal showing, not data or cell (wifi still works, but thats a different story). has anyone experienced this and know how to fix it? im guessing modem flashing, but not entirely sure. can someone please point me in the right direction? Thanks in advance!

I believe you need to do a factory reset. Backup your data first!
Sent from my SGH-T999 using XDA Premium 4 mobile app
The first thing to troubleshoot you should do is flash back to a rooted stock rom and make sure the data is working there. If so this will rule out any sort of hardware problem. You didn't say whether or not you did but you can also try fully wiping the phone (dalvik/cache, system, and data), re-download the rom incase you had a bad one the first time and reflash. Other than that check that maybe check the apn settings.
Yup I ended up doing that last night..im back on the stock root injected rom. So im still rooted and network now works! So im glad. How would I flash a rom without losing the network this time?

Now that you have flashed back to stock a full wipe has been done in the process. At this point all you can do is flash it and see, but as i said i would redownload if you plan on using whatever rom it was you mentioned in the OP. I would also do a full nandroid backup to save the pain of using odin incase it doesn't work. I imagine the problem was with lingering files/fragments from multiple flashes that were causing the problem, in any case whatever the problem happened to be it was software related.
K will do. Its just weird because the md5 matched and everything..but I will for sure download the rom and gapps again. Thanks for the tips!

well, i finally got the service to work after flashing a rom. it still remains a mystery to me tho, i used to always use the illusion rom everyday, for months. i decide to flash the same exact one but no service, i download it a couple more times and still no service after flashing about 3 or 4 times. i tried a completely different rom and the service is active. i dont understand why and cant figure out what is so different this time hah. o well, im just glad its all working now even though its with a different rom. thanks for the help guys!
ok, im back =[
i was using the carbon rom with no problems, it was working great, but just a half hour ago i was listening to music and texting (i always do this), and then phone just turned off. I tried to reboot it but it wont! it always shuts off while booting. i made it to CWM, but it turns off while in CWM. i also made it to download mode, which led me to assume that the phone is not bricked, but it doesnt stay on download mode, it just turns off randomly. i figured maybe it was battery, so i tried another, and no change! does anyone know what the issue is? i cant figure out how to keep the phone ON, or why its not staying on.
btw, i got it to boot completely just once, and it was acting up still. any ideas? please help
Thanks in advance

What is the bootloader and baseband version on the phone? Which version of stock are you flashing?

[Q] Upgraded to 4.4.4 No longer have cell service?

http://forum.xda-developers.com/galaxy-s4-tmobile/development/moving-please-post-t3009561
flashed that
Wifi works. Data/Calls do not.
What do I need to update?
Tried another 4.4.4 rom, same result
You probably have to update your bootloader, I had the same problem a while back. I Oden the entire 4.4.4 tmobile firmware and haven't had a problem since.

You need to read through the thread and see how other folks fixed the problem. The rom thread that you flashed.

Well If you really need your phone to work properly, receive and make calls, working mms and have long battery life and not blow up, you may have to settle for stock /touchwiz.
