[Q] Roaming not working - Galaxy S III Q&A, Help & Troubleshooting

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?

[SOLVED] Mobile connection and SMS stopped working after messing with ROMS

Hi guys,
few days ago I've decided to move forward with Fusion Update 7 ROM to Fusion Update 8. Procedure was about normal beside the fact I had also purged SD card. Upgrade went well, but:
I cannot get mobile connection
No SMS can be sent
No matter which ROM/RADIO I had flashed after my previous move everything beside those two is working. So I can get WIFI connection or receive SMS, I can also call and receive calls.
My configuration:
- Hardware: HTC HERO GSM (white)
- Recovery: AmonRa 1.7
- ROM: FROYO_2.2_elelinux_v2.2 (at the moment)
- RADIO: 63.18.55.06OU_6.35.15.01 (at the moment)
Additional info:
- SMSC is set correctly (checked using *#*#4636#*#*)
- APN list is correct
- rollback to vanilla 1.5 ROM from RUU not helped
- other SIM cards from other carriers work the same way
I trying to get some debug information using adb, but only thing I can find is that ppp connection is missing in netcfg.
Do anyone know how to initiate Mobile Connection through adb shell ? or anyone get similar problem before?
Thank in advance,
Problem solved. During messing with ROMS my SIM card must been somehow damaged.
After more tries with other SIM cards my phone started to work finally.
You are missing the correct apn settings for your mobile data and also missing or have the wrong SMS service number, have a search on the forums here, or Google and you should find them. Always worth backing these up or writing them down, as not all rom's have necessarily got all providers son's included.

Thank you for fast reply.
I checked those before:
SMSC:
- refreshed with *#*#4636#*#* and those looks correctly for my carrier
APNs:
- there where missing fields in APN config which I've updated according to carrier configuration
Still nothing had changed.
I assume that it must be some kind of config that do not change between ROMS.
(I will update first message with those info.)
Did you checked with an other SIM/carrier?
Yes I did.
Effects where the same.
I've also rolled back to vanilla 1.5 ROM from RUU. Nothing changed.
It must be some kind of external configuration that is not changed via ROM replacement. Can this be true?

Can't Send / Recieve SMS after 2.1 Update

Hi, After updating to 2.1 i noticed i cannot recieve text messages. I couldn't find on forums how to fix this but i believe it might be something to do with APN. I tried looking but can't find it on forums.
Can someone guide me through this please. Maybe it might not be APN?
Thanks.
Firmware version : 2.1 -update 1
BB version : 2.1.52
Kernel : 2.6.29
I use ATNT in California
Do you have signal at all?
Here's a thread with apn settings and how to update to X10a global generic 2.1.A.0.435
http://forum.xda-developers.com/showthread.php?t=1012380
Everything works fine in my phone beside send/receive text from other callers.
I can call/receive calls, signal, internet, etc.
Another extra thing about text, I am able to receive text if i type a code EX*data# to know how many data u used this month).
I tried the apn settings JBAgent posted already, it doesn't work.
Well i would make a backup of everything you want, then download Sony Ericsson Update Service (SEUS) and run it which will fix your phone but wipe everything on it.
Before you do that, have you gone to settings / Sony Ericsson / Auto search for internet settings? Then call At&t and have them check your connection. It could be your sim card.

[Q] MMS problem

Hello
I got a big problem that i can't resolve alone. I configure a new APN on my tab and i can access 3G+ but it seems my MMS profile doesn't work. I can't send or receive any MMS....
I join 2 different configurations for Android , one for HTC and the second for Samsung galaxy tab. Anyone can give me any solution to sent an MMS with that?
Thanks a lot!
Pleaaaaassssse help!
I don't know about samsung tab but if it happen to me I will flash a new rom.

It would be helpful to post a little more details on your Vpad7 basics so that maybe, one of us can help figure it out or test our ROM:
Let's take a simplistic step-by-step approach first -
a. are you using stock/factory ROM or rooted, custom ROM including verison #
b. your mobile carrier for the SIM card, both SMS and MMS enabled & working on another quad-band GSM phone
c. SMS working on the Vpad7 as is - both incoming & outgoing
d. using the default Messaging feature/module installed or using something else,
and if you haven't try it already, download & use Handcent for SMS/MMS
f. if you have already done all or some of the above, do a Master Reset on the Vpad7 first to clear all the existing settings, boot into RECOVERY to wipe dalvik/cache/system, and then flash, as suggested, a different custom ROM.
g. any technical support or help from your mobile phone carrier
Cheers - mastering everything on the V is a challenge !
First , i've tried with standard rom. No succes. Then i flashed my vpad7 , installed TJ's rom and... same problem.
BTW you're true , i'll try my sim on another phone , try MMS. And i'll try to put another sim in my vpad7 too.
But , i just think one little thing is missing , because when i look at the other froyo's config , some little thing are changing between diferent phone model.
So , i think viewpad need a personnal configuration.
I got Gosms and tried to configure MMS on the program settings , but same problem.
I've called the technical support but can't help me and told me : "we have some configuration on website , try these , if it don't work , not our fault"
Thanks for your help
Does anyone can send me any working config for MMS on viewpad 7? Just want to see what's different.
THANKS...
These are mine under Settings > Wireless & networks > Mobile Network > APNs, they're OTA/downloaded automatically & self-configured
AT&T MMS (wap.cingular)
Proxy (Not Set)
Port (Not Set)
Username & Password (Not Set)
Server (Not Set)
MMSC (http://mmsc.cingular.com)
MMS proxy (66.209.11.32)
MMS port (80)
MCC (310)
MNC (410)
Authentication (Not Set)
APN type (mms)
Note - these are nearly identical to AT&T WAP, which is usually configured for web browsing with data enabled.
Ok , i tried all solutions and then:
My sim works on other phone , i can send MMS .
Another Sim on my viewpad ( different operator) , once configured , worked. So it's not a viewpad or sim problem , just a Digicel configuration problem.
Any solution?

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

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 ?
