I have already asked in the specific Q&A section for my phone but I thought i'd branch out to the community as this seems to be a general phone query.
THE PROBLEM
I have a problem with my phone where I can't receive or send text messages or phone calls however i still have signal and can use mobile data. The problem occured from a rom flash coming from Kalgecin's Unofficial CM10 builds to Chameleon 1.2.
ATTEMPTS AT SOLVING
I have contacted my provider's, T-Mobile UK, they have told me that everything is fine with my settings and have suggested I take the phone to a T-Mobile store.
I have used my sim in another phone and everything works.
I have used a friends sim in my phone and the same problem occurs
I have made sure the SMSC is that of my providers T-Mobile UK.
I have tried flashed a generic stock ICS 4.0.3 rom.
I have taken the phone back to T-Mobile 4.0.3 stock.
I have tried the following but the problem still persists.

PDA I9100BVLPD
PHONE I9100BVLPB

Hopefully someone can help. Cheers

i recently got a Galaxy s2
but i am having some problems with the network (have read many threads, but no fix so far)
so, the phone was 2.3.3 version
i flashed via odin stock roms to 2.3.5/6 version
but - no mobile network, changed different roms and on the KI3 i get 2-3 days using the mobile network, and then it loses the network...
any ideas what i can do?
FIXED
Try flashing different modems until you find one that works well for you. There are a ton of threads on here which have links to modem downloads (and many of them are hosted on sites that still work), search for them.

i tried 4-5 modems...and not working..that's why i said i have read many threads
obviously i have to flash all possible region modems
Return phone to service centre .

Update:
so i flashed few more modems (like 7-8)
and i can see the signal strength is ok -around -60/-70 dBm...so obviously it's ok
and again for a couple of hours network was fine then,,,disappeared
*can't get it back to service center
other ideas?
Has your ime changed?
Does this only happen with your sgs2 or does it happen if your sim is in another phone?
Are your apn settings correct?
Sent from my GT-I9100 using XDA App
IMEI is same, no change
the APN settings are fine
the sim card works perfect with other phones, that's why i think the problem is in the phone
will try with other sim card in same phone and will post result. while waiting suggestions
What model do you have? Check on the sticker under the battery. Checking in settings doesn't show the true model. Eg, I have an I9100T but in settings it shows as the I9100 because I use a I9100 rom. I get crap reception on all roms until I flash an I9100T modem.
Sent from my GT-I9100T
it's a gt i9100
so same as in settings
still no other sim card to check
did you try the kg9? in which modem you were in 2.3.3? did you try to return the same? if it does not work I think it's best to bring your phone in for repair
i think no, so i will give it a try
* i am in france btw - do you use the same modem?
with my andy rom i'm in LPB modem and it work very fine but before, i was in ki4 or kg9 and i don't have problem with it
So FIXED
obviously it wasn't a modem problem, but sim card - wasn't working with no matter what sim card. So i did few times the hard factory reset and used again Helroz application from the market, and on the 3rd time, it worked.
10x for the help and the advices guys
what leaves as a question is : am i going to be able to flash custom roms, and what is changed after the use of Helroz application, so i can do backups?
Hey guys,
This is my first post here so please be nice I will try be as informative as I can!
Last week my aunt got a Samsung Galaxy S2 as an upgrade after my recommendation. She loved the look of things and liked how she could access Youtube and Facebook but then she got locked out of her phone completely and couldn't get back in because she didn't know her Gmail account.
After a bit of research I found out that I should do 'Hard Reset' and all should be back to normal afterwards, I did so and everything looked okay.
After giving the phone back to her my aunt said she no longer wanted it and gave it to me because it was too 'complicated'. Obviously I was overjoyed as my current phone does not even compare to this beast!
I put in my Orange sim, (hers was Orange too) turned on the Wi-Fi to update all the apps not even noticing that the 3g icon wasn't on. I could see the phone had some signal so I thought everything was okay. It was only when I tried to call my dad of the phone that I realised something was wrong. It said 'Mobile Network not Available'.
I have found many threads about 'rooting' or IMEI but I don't understand what they mean as I am a newbie in all of this.
I would send the phone for repair but it does not have insurance so that's a no go. The phone came unlocked too so I don't understand why it's doing this. The sim I put in works on my old phone so I'm pretty sure there's nothing wrong with it.
What should I do?
Looking forward to your replies
See * HERE *
Remove your battery and your sum card.
Wait 10 seconds put them back in and reboot.
If problem still exists go to
settings > wireless and networks > mobile networks. Select your carrier network.

Thank you for your replies samgalaxys2 and dred_up, I appreciate it!
I tried doing what you said samgalaxys2 but nothing's changed, I tried doing it myself before but no luck
In reply to your questions on the other thread I can confirm that my sim works as it works on my old phone. I can also create contacts on the sim too.
I don't know what the EFS folder is but when I dial that number you said (*#06# ) I can also confirm that the IMEI is the same number shown in my settings and underneath the battery.
What should I do?
Wiska.
The fault = put your sim in the phone then not working .
First step has to be to get a new sim .
That would be followed by either a return to a service centre or via XDA a flash of new stock firmware .

Have you tried the Access Point Names in the network settings, mine changed it's self after flashing a new rom.
Hello JJEgan, I have tried various working sim cards and it doesn't make a difference, I even tried a brand new T-Mobile sim. In the 'About Phone' section I can clearly see the Sim's name but it always says Out Of Service underneath.
I have tried that too s.d.oconnor, at times it doesn't work and when it does it says something like 'Network Updated' but nothing changes.
What do you guys mean by 'Flash of new Stock Firmware' & 'Flashing new Rom'
Sorry for the amount of questions guys, I have never experienced something like this before

Hmm okay,
I followed the thread and had to do it at-least 3 times before I could do it 'correctly'
I managed to get Ice Cream Sandwich OS on the phone and although I could now use the sims internet I can't use it to call or access my voicemail.
What can I do to fix this?
If I have to download a new rom could you copy the link because I think that maybe that's where I went wrong?
I am sorry but I tried my best as it is my first time doing all of this.
I think the Rom should be an XX as the phone and myself are in England plus my network is Orange
Wiska.
You can use the Dutch firmware XEN without problems...
Also is your fone a i9100P (NFC) or standard i9100?
Or take fone into Orange or a Samsung repair centre to have it checked out.
Hmm do you recommend I Flash it again and get XEN?
Do you think they'll repair it even though it has been flashed? I've got ICSandwich on it and I don't think Orange has released it yet lol
I tried to change the APN but nothing is happening

If it was a Orange (UK) branded phone, then first download, install and run Triange_away app. This will reset the custom rom flashing counter and take away any triangle at boot up (if present).
Next you need to download and flash the BVKJ4 rom from * HERE * - it is the latest official Orange UK ROM. It will wipe the phone to factory setting and you will loose root. It may solve your problem, but if it doesn't it will put your phone back to valid warranty for the service centre.
Sorry for the late reply, the amount of work college gave us yesterday was just too much!
Thank you for the link fred_up but the links are dead
Thank you for trying to help though, I really appreciate it mate!
Anyone know what I should do?
Search for the stock rom you're after on Samfirmware.com.
Edit to add - Make a note of the rom details from Intra's thread (the one you were linked to where the links don't work), that will make searching Samfirmware easier.
Thank you MistahBungle!
I am downloading what looks to be the firmware I need right now so fingers crossed it works!
Many thanks for the help mate! I will keep you updated if it works or not
I tried the latest Orange one but that didn't do anything, I then tried using the Carphone Warehouse one and although the 3G internet stuff works I can't call or text!
This is so annoying lol, any advice?
The phone isn't locked or anything as my aunt gave it to me, what can be the problem?

Hello,
I will have to give background info on this before anyone can help so bear with me please :.
I live in Pakistan and I bought a i9300 directly from samsung. In the beginning of the six months i owned the phone, I never rooted or put custom ROMs on it. Then unfortunately I got SDS. I gave my phone to a local repair shop (non samsung, but highly reliable, I bought the phone from there) who switched the motherboard on the phone. After I got it, I rooted it and started installing custom ROMs on it. First it was cyanogenMod, then Paranoid Android and Supernexus +AOKP and others. Everything worked fine. Then I installed Omega ROM (Samsung based ROM which changes the modem). Everything went fine, but I was unable to connect to my network (No texts, calls, data connectivity). It detected my network(Ufone) but was unable to register on it when I manually tried to. I mega-wiped my phone, cleared cache and factory reset and did everything. Alternatively, the following steps I also tried.
1)Checked if my IMEI is intact. It was. (I have EFS backups too)
2)Checked if my serial # is different. It is still the same (No need for Ariza Patch)
3)Checked if my SIM works. It does on different phones.
4)Checked my APN settings. They were fine. I even manually changed them to match the carriers
5)Changed my CSC settings (using the playstore app). Still doesnt work.
6)Checked different modems from the appropiate thread (I have tried Europe Unbranded, Middle East, Egypt and many others)
7)Restored nandroid backup of original stock 4.1.2 Sammy ROM, still not connectivity.
8)Flashed using ODIN, the stock 4.1.2 ROM for my country (Using SAM mobile). Still no connectivity.
9) Matched my RIL with my baseband (using the GetRIL app), still didnt work.
Stock Samsung 4.1.2 ROM details before OMEGA flash in which everything worked:
AP: I9300XXEMA2
CP: I9300XXELLA
CSC: I9300OJVEMA1
This has happened to me the 5th time now (Phone is currently at the repair shop) and I have sequentially tried every one of the steps I have mentioned. I called up the repair shop and they said that I can come tomorrow and pick it up, all they have left to do is "SIM UNLOCK "the phone. That confused me a lot. I will go tomorrow and ask them details as to what they meant by that. So my question is basically this:
1) Is it possible that the motherboard they put into my phone is from a software-unlocked phone not a hardware unlocked? (Is the 'unlock' on the motherboard of the phone)
2) Is there a way to find out if my phone is software or factory unlocked?
P.S. Every single time I hand in my phone, I obviously unroot it and install stock on it (regardless of the fact that it doesnt connect to the network). But every single time I get my phone back, its ALWAYS ROOTED.. I even asked the technical team guy and he had no idea what I was talking about (repairmen here dont have that much of knowledge, they tend to follow guides online, thats it). So could it be that my connectivity issue is just because its software unlocked and not hardware?
Thank you!
Anyone?

Not a genuine service centre then .

all correct for network suggests a hardware fault .

But it's not a hardware fault? I mean whatever they do, they have to root the phone to be able to do it. Any idea what settings or configuration they might have changed using root for it to connect which I haven't already tried?

Anyone have the issue where the SIM card isn't recognized? I'm on the RR newest ROM and the card isn't being recognized...I'm about to try the stock ROM and see how that goes.
Similar problem
I`m in a similar position I think. However, my phone recognizes the SIM but when checking the SIM-status the mobile radio seems to be off. I can´t change preferred network type, it just jumps back to "TD-SCDMA/GSM/WCDMA/LTE , I get no results when searching for mobile networks and when I use the *#*#4636#*#* - menu the "Turn on radio"-option wont respond. I`m on latest stock firmware and the phone is still displaying IMEI-numbers. I bought my unlocked European version of Oneplus X yesterday on an auction site, the seller has good reputation and he claims that it worked fine for him. I got a new SIM-card today thinking that would have solved the problem, no luck there however. I also did a hard reset and downgraded to an earlier version of a stock firmware and the error is still there. I noticed I had TWRP v.2.8.7.0 blu_spark r5 preinstalled when I bought it, its a custom kernel right? Could something related to the kernel be the root of the problem or the baseband? Any suggestions on what to do next?
Hi,
Its been very recently that I bought SGS3 i9300 *exynos not qualcomm, in used phone and I'm pretty much in the dark what material does SAMSUNG puts into his phones to make them full of *beep*.
I was running XXELKC 4.1.2 firmware and I decied to just root > recovery > CM12.1 or CM13 SGS3.
Well everything went well but I ended up with no sim card error. Then I thought that might be my sim card is corrupted so I put in a newly replaced microsim card and put in the phone still no good.
Then I did wipe system+cache+dalvik+data and installed CM13 from TWRP. Still ended up in no simcard error.
Then I got to know about XXEMG emergency zip radio which is cross-efs compatible so I flashed that one. I ended up in NO IMEI/Baseband
I flashed XXELKC PDA file back and phone booted with its own IMEI number preserved.
Now I have working DATA connection but phone doesn't register on network for calls/sms.
What is the possible issue here?
I cannot find working modems link as the REF thread has dead link to modems.
I do not know how to fix this phone, and I've made myself a promise that this is my first and last samsung phone ever. Please help through this one for the last time, even it means working phone on a JB 4.1 firmware but I want the simcard/network/calls working to resell it and get rid of it.
Thank you for actually roaming around in Q&A section and taking a look.
Nobody?
