[Q] National data roaming in CyanogenMod 11 doesn't work. - Galaxy S II Q&A, Help & Troubleshooting

Hi. Yesterday I installed latest nightly version of CyanogenMod 11. Before this, I was using [LINARO/SABERMOD] unofficial CyanogenMod 11 but I had problem with data roaming. I thought that in official build this isue had been solved. Unfortunetely, my data transfer still doesn't work. In the place where I live, there is very weak signal and I have to change my operator to another one manually. The problem is, data transfer works only with my parent network. I enabled data roaming in options menu and I edited build.prop file, where I set dataroaming=true; (although data roaming was enabled, in this file value was set as false). Tell me please, what to do. I don't want to restore stock rom.

Bump! I'm having same problem using CM11 4.4.4 (nightlies) for my S3-i9305. My carrier uses its own network but also uses another one as MVNO. Well, I connect HSDPA 3G on its own network but don't when using the MVNO, only Edge/GPRS (2G). Same happens using a SIM from another country, data works but only on Edge/GPRS (2G).
Yes, data roaming is enabled (the proof is that data works, but only 2G not 3G).
Any ideas? Thanks.

Solved
Ooops, it results it is a question of bands: the phone does not have all the bands we use here, that's it.

[Q] Roaming not working

Hello there!
I recently installed the UltimaRom V.6.0.2 on my Gti9300.
Everything seems to working grand other than the data connection which does not function, 'mobile network state' is 'disconnected' and 'roaming is 'not roaming' under status in the settings (please see attached screenshot) so cannot choose internet, whatsapp etc.
This has been checked in the mobile network options, but this will not function regardless. I then thought it might be due to the option to install the baseband version and I chose I9300XXDLI8. Is this where the problem lies since I am receiving and still able to make calls and texts.
I am a t-mobile customer in the UK with 'everything everywhere', I believe the APN settings are OK. I can still send and receive MMS, but no data connection...
Please help me out!
The Rom on installation gives me the choice to install the following baseband versions:
XXELJ2
DDDLJ1
NEDLI1
XXDLID
XXDLIB
XXDLI8
Have I installed the wrong one?

[Q] glaxy s ii data network not working.

I had custom android 4.2.2 and i reverted to the original 4.1.2 rom. Now mobile data isn't working. The phone was originaly on orange ro now it is on cosmote ro. It worked Before on cosmote with t e original rom and the custom one. I sent an sms and recived setings but it still doesn't work. It says it's activr bot i see no icon in the notification tab.
Any ideea?
Have you tried checking the APN settings?
I have an issue where i flash my phone with SlimROM and then Chrome and Whatsapp is not working on data. Then I realize that the ROM auto select the wrong APN settings. I entered the right APN settings and I have no issue with getting data.
Also check if all the apps are receiving data via wifi first.

Wifi works. I'm wrighting from my phone now. The settings where wrong but changing them is the first thing i tried but i didn't work.
I never had thisproblem before even when i flashed custom roms. It feels like it doesn't activate the net even if it says it does.
Got it. I had the settings for gprs and i needed the ones for broadband.
Hi everyone,
Thanks for your comment. It turns out the ROM was selecting the wrong APN by default. I switch the APN and updated the settings. Now it works like a charm

[fix][data connection issue][cm11][updated]

Hello guys everyone were worried about the data issue in cm11 so here I am with the fix for that
Please not I am not at all responsible for any damage to device Please be careful
Bug:
No data connection even after installing the fix
It works for some people that too only 3G
Fix: First install the data fix if you haven't Installed
Open dialer and type *#*#4636#*#*
Open the phone information
And In network mode change it to GSM only if you are in 2G network and when you want to use 3G set it to WCDMA only
And voila data will be working fine
TIP: when you want to use 3g in sim1 and it is using 2g then change the sim slot and in second sim slot you will get forced 3g(only 3g works) and when switching back to stock you will always find the option to set the preferred type . so you can enjoy data both on CM11 and stock without and issues
Hit thanks if you like my work
Thank you

Sim 2
Data works only in sim 1, while opting for data in sim 2 the error shown is 'error in subscription...' Any fix for that ? Indian variant.

Do one thing remove SIM 1 and dial the code set it as GSM only and then insert back sim1 and check it should be working. Since it won't support both 3g (which is set by default)

Mobile network wont work.

So I installed Cyanogenmod 12.1 Android 5.1.1 to my Sony Xperia Z2, and after installation my phone wont connect to mobile network. Wifi works, and phonecalls work. There is exclamation mark in the signal icon, and when i connect to wifi it disappears. I didnt find any mistakes in APN. Could it be wrong baseband? Or what could it be?
Maybe internet settings are missing ? go to settings>more> internet settings> download settings for Internet and MMS. (I had the same problem but it is working fine now)

Check APN settings under the Wireless & Networking menu.You’ll find that no APN has been set. You’ll need to choose the one for your mobile operator or worse – manually enter the APN settings.After setting the APN you could need to restart your phone

I have dont that, and No help.. Could it be the baseband version problem? Im trying to install stock rom, test it if it then would work..
Call *#*#4636#*#* to enter phone settings or use this app and select Additional Info
Select Phone information
Set prefered network type to CDMA auto (PRL) and wait until your phone connects to 3G
Change prefered network to LTE/GSM/CDMA auto (PRL) maybe this works? If not I am sorry

The exclamatory means that there is no internet access. Ask your service provider for manual internet settings.

Now i have stock rom ranking,and after i installed the internet settings from mobile network settings, mobile data started running. In cyanogenmod i didnt have that option in settings so I think thats why mobile data didnt work on cyanogenmod.. How can i get cyanogenmod mobiledata working, without the option to install network settings?

Resurrection/LineageOS| IMEI needing restore?

I'm hoping someone might point me in the right direction for restoring cellular functionality on a recently flashed GT-I9300 ?
Essentially what I've attempted to so is up-cycle an old Samsung Galaxy so that my son can communicate with myself and his grandparents on Signal.
System: RR-N-v5.8.5-20180914-i9300-Unofficial
Recovery: TWRP 3.02.1
RR is up and running (and quite slick!!) and generally there appear to be no issues apart from:
- SIM being undetected
- Baseband version: "unknown"
- Settings --> Wireless & networks --> Cellular Networks: APN / Network operators / Preferred network type; these are all greyed out
There's a brand new sim card in it (two others have been tried); I just need a way of helping RR discover the correct settings needed for cellular functionality? I wondered if there might be a modem config file somewhere I could edit - but I've not got that far yet, and I'm not even sure if this would be the right approach. Any suggestions would be greatly appreciated
Hi,
I presume you have no backup of your /efs partition ?
Have you tried another ROM ?
