You need to ask the network if they are having problems .
Have you checked /remade your network settings ??
Could be a rom problem a modem problem a sim card problem or even a CSC problem with wrong settings .
Check settings clean sim card that does not help put your phone back to a warranty state flash stock rom and clear rom counter . Test if faulty take to a service centre .

Im on 3 also i have had a few times the same problem mate, lets say maybe 4 or 5 times, it usually happens if i lose my internet connection it still shows me having signal but cant make a call or sms. i got no answer from 3 either
Check the status screen. I get this and when it happens where it should say T-Mobile it says Emergency Calls Only. I figured my SIM card was at fault so wedged some paper behind it to hold it in place and the problem has almost completely stopped.

Are you guys running an I-9100T from 3? All modems from any rom you install won't work with the T. You'll need your stock KF4 modem.

I had a similar problem. Read more about it here:
http://forum.xda-developers.com/showthread.php?t=1225849
tried going back to kf4 still no luck its only in certain places in me house where it does it everywhere else i have 1 or 2 or none at all bars of signal
3 customer service rang me up told them i wanted cancel the contract bcus of it. they knocked the contract price down from £30 to £25.75 for the text 500 plan with them. bit annoyed that i can only get signal in certain places of me house but cant argue on the price as well as gettin the phone for free
because 3 dont have a 2g network in the UK so if you dont have 3g coverage it will show a network signal but you cant make calls or sms
I'm having the same problem but with o2. I lose signal regularly at home as I live on the perimeter, but when I get signal bars back againwhen i go into town, it tells me that the network is unavailable. I have to switch off and on again to re register and then it works fine again until the next time the signal is dropped... It's annoying in the morning because i can wake up and see full signal on the phone all morning, but people are trying to contact me and not getting through because in reality, the network is not connected! I'm sure o2 have a 2g network, so I would presume it's a phone issue...
Hi all,
I live in France using SFR network and I get the same issue here using KI3 but I had the same problem with KH3.
the behavior on the phone is network seems to be good everytime/everywhere but sometimes people who try to reach me go directly to my voicemail and I receive sms with some delays.
When network works again, I mean I don't see it but I know it because I receive a couple of sms at the same time and a call from my voicemail
it means that my phone seems to be connected to the gsm network but is not, It loose the gsm network...
If you can give me your experience.
thx
I've got the same issue. (tacticman), I'm also on SFR network, i had this since KH3, never before. Now i'm on KI3, it's still here.
I always use CF-Root kernel, i tried to wipe, restore old backups, it does not change anything. I also tried GS II repair tools, nothing too...
The only thing I found to solve (temporarly) the problem, switch to offline mode (mode Hors ligne in FR) and then disable it.
But the problem occurs very often, it's very disturbing.
My IMEI number is still here.

Hi there,
Since a few days, I've got a serious problem with my SGS2, it randomly loss any networks, saying that the flight mode is on. I tried to flash with another firmware ( stock KE7) it change nothing.
Any idea?
This is a firmware issue with the modem. Mine did the same thing. KE7 modem is horrible. I flashed to KF2 modem and I don't have this problem anymore.
Sent from my GT-I9100 using XDA Premium App
i believe this is related to the network itself. for my 2 other phones before, whenever i am AUTO network Mode, many callers used to call me reporting 'My mobile was off'... also with S2 the same issue.
i switched to GSM mode only, LOSING my NETWORK Data SPEED, for this ..
i hope future firmware can solve this with as suggested above, Good RADIOS....
The problem is that i've already tested with another provider's simcard and i've got the same issue. I tried with some firmware (stock KE2, KE7, KF1, Litening 1.4) but it change nothing. I'm from france with 'Virgin" provider if this can help.

I'm on Orange UK and that happens to me quite often. It's something to do with the network and how it handles the switch from gsm to udma(I think, anyway). Sometimes the network doesn't fully recognize you've switched from one type to the other and reports your phone to be offline. It doesn't usually last long but if someone tries to call me during that time then I'll get a text message when the network catches up to tell me I've missed a call.

I don't think the problem can be fixed on the user end. I had the same issues with a Nokia N80 and N97 mini before I switched to the SGS2. It's apparently a common problem that all networks sometimes have and the only way it'll ever really be fixed is if the networks improve how they handle the switch.
I think it also depends on where you live. If you get a constantly good 3G/H signal then in theory the phone should hardly ever need to switch to GSM mode, but if you live in an area where the signal is not so strong then it might switch more often which will cause the problem to be more severe.
You could of course try setting the phone to WCDMA only which will give you good speeds, but then if you drop out of 3G range you'll lose the ability to make & receive calls anyway. It unfortunately seems like a lose/lose situation.
As for the flight mode issue, I really have no clue what is causing that. Have you tried hard resetting and/or flashing new firmware?

Change your phone..
I had the same problem on my first SGS2..everytime when gsm/wcdma auto is selected..phone randomly looses internet connection and radio switches off. In gsm only mode..everything is fine. Got my second SGS2 and phone is perfect..no loss of data connection even in the worst coverage area..
You can read "serious issue on 3g" thread in the general forum and see if you are suffering same symptoms

Hi I am currently a T - Mobile customer and when I originally bought my Samsung Galaxy S2 with the company, I thought I could take advantage of using both the T - Mobile network and 2G services of the T - Mobile Orange Network.
However after successfully using it for the first 2 weeks, after my KE7 firmware update, I have an unbranded phone, it did not connect to the network anymore, stating, even if I manually select T - Mobile Orange in GSM mode only, Cannot registor with network, Unable to connect, then it states it is registered and yet I have emergency calls only stated and not either T - Mobile or even T - Mobile Orange. Then it will not connect to either network manually until I restart the phone.
I have since flashed my phone with various other firmwares, am currently on cognition s2 1.13, it's a great Rom, and still the same thing occurs.
I have contacted T - Mobile, they can't fix it, I have took the phone to a Samsung Repairer and they couldn't see anything wrong, stating it was a fault with Orange, as the guy in the shop's T - Mobile branded Galaxy s2 did the same.
Anyone solved the mystery, or is able to explain the issue to me?
It's doing my nut in, I have had phones like these for years, flashed them and enjoyed them, and usually work things out for myself, my last phone was an Samsung I8910, which was great with custom firmware support and I must say the Galaxy s2 is by far my favourite ever phone, but even my Samsung Omnia I8910 works properly on T - Mobile and Orange, and the latest and greatest phone won't!!
Have you tried flashing a different modem? Seeing as the cognition rom is based on I9100XXKG1, I know of a couple of forum members that have had trouble with the KG1 modem, and had to revert to the KF2 modem.
Worth a try? It won't wipe you phone of anything daft either.
List of official modems: http://forum.xda-developers.com/showthread.php?t=1131950
Before you do anything, can you dial*#1234# and just check what phone software is installed?
Thanks for the option Unfortunately I have tried the KE2, KE7, KF2 and KG1 Modems now, none of them have worked. It is really bizaar as the bloody thing works really well on T - Mobile, when there is coverage, plus the 3 and H is great speeds when they are in coverage, it just won't switch to Orange

one moment, I'm on t-mobile aswell.
text YES to 2121.
Homer moment: Doh, you cant text can you?
Just for reference, I'm with Orange and in my network list I have both "Orange" and "Orange and T-Mobile". I can connect to the Orange one fine, but not to the other one. It does switch to T-Mobile sometimes though. I've seen it do it.
Hi again, I have text yes to 2121, and it was working on my phone before. So yours has no issues then?

Unfortunately if I let mine automatically switch network, it switches to emergency calls only if I am out of a t mobile network range, not orange, and it used to switch to orange no problem
Then when it is in emergency calls only, I have to turn it on and off to get it to work at all, as it will not register back to T mobile
My last attempt......when you go into wireless/mobile network settings, is data roaming ticked?

Yes it is, cheers for all your help. It's very frustrating and I can't fathom it out, so cheers for trying yourself
You don't need data roaming ticked in order to use Orange. T-mobile and Orange are both considered 'home' networks.
I'm on T-Mobile without data roaming ticked and it switches automatically to Orange without any issues. Might be worth phoning t-mobile up and seeing if there's some sort of issue with your account.
I installed Lite'ning Rom and found that I couldn't connect to Orange on my unlocked tmobile sim. Turned out that I had the "com.orange.authentication.simcard.permission" apk missing.
Downloaded it here:- http://www.contentsd.nl/apk/SimServicePermission.apk
and installed it with titanium and registered ok on orange.
Hope this helps.

Hiya guys. Sorry to jump on this thread but I am having the same issue as OP. I'd just like to give you an update on what I know so far. It is a nightmare trying to speak to someone at T-Mobile who actually knows whats going on, but I was persistent and got through to an engineer who said that they are having transmitter problems in east anglia and surrounding areas...not sure if you are in that area or not. Unfortunately all the engineer said is that they are working hard to a. figure out what the problem is ang b. fix it! He also could not give me an ETA and said that the only way to get back onto the network is to reboot the phone a couple of times. Not ideal, but I though it was something to do with the VillainRom that I flashed...so here's stupid me flashing stock, bricking/unbricking the phone etc etc only to find out later that its not the phone...on the plus side I have amazing battery life now haha who would have thought ey!
Anyways, hope this information is useful to you all.

It is not a ROM issue - it is a T-Mobile/Orange fault

Absolutely right Steph, it is not ROM related.
T-Mobile have acknowledged that there is a problem with registering T-Mobile customers on T'Orange cell towers.
I've been having this issue for a couple of weeks now (also in East Anglia), and after a lot of perseverance I got transferred to Level 2 support (Technical Support - not Customer Support) last Monday. They said there was a 'rectifier problem' on a mast in Henny Street, near Sudbury, Suffolk at the end of June and it has had a knock-on effect on other masts in the area. It was/is a level 2 priority for fix.
I wasn't happy with that explanation as it happens all over Suffolk!
Still with the issue on Thursday, I called them again and got straight through to Level 2 as they had marked my account as an on-going problem which Customer Support (in the Philippines) couldn't handle.
While explaining in detail the 'Your SIM does not allow you to connect to this network' problem the Guy I was talking to received an internal notification that they were aware of issues registering on T'Orange cells, that they'd known about it for 72 hours, have no idea what is causing it, and no eta to fix.
I've been using a forced connection to T'Orange for the last couple of days (poor T-Mo signal in house which always caused it to hunt for T'Orange anyway). Downside of course is that it won't get a 3G signal when forced into T'Orange mode.
Still happening today so need to give them another prod...
Oh, and I found this thread searching for answers - I don't have a Galaxy S, I have a Desire. Further proof that it isn't ROM related.
I'll update when I find out more from them.
Aaron
Just spoken to them again, problem is still on-going, they are still investigating and looking for more samples of the problem to try and isolate the issue. In light of that I would suggest anyone else having this to phone them and ask for Technical Support and register the fault - the more samples they have, the better chance of getting it resolved.
In other words, they still don't know what's causing it or when they'll fix it.
Hi all.
ive been floating around the forums for some time as an unregistered user but i now have to resort to posting for help.
fist of all heres my details
Android version 4.0.3
Baseband 19100XXLPQ
Kernel 19100XXLPQ
Build IML74k.XXLPQ
ok so first of all id like to know if it matters that the serial on the phone does not match that on the sticker behind the battery although the IMEI number does,from what ive read on the forums this may be because i flashed a non official ROM?
when i originally flashed to ICS the signal was poor but i still used the phone and now i have no signal at all at home,
if i try and dial a number i either get `mobile network not available or not registered with network.
ive flashed the phone with so many roms,kernels and modems now that im in a complete mess with what ive actually done.
i checked with my provider `3 UK` if the phone was/is blacklisted but its not,ive had the sim replaced with a new one and also tried another 3 payg sim.
im not normally one to give up but i admit im getting close to it.
in hind sight i wish id taken a full back up whilst on gingerbread or even never upgraded to ICS in the first place ..ah well
so my thanks in advance if someone can help me and apologies in advance also if ive missed any information out.
cheers
theredi
just to add to this,
i just stood outside and scanned for networks,the 3 network appeared but when i select it it says:
your sim card does not allow a connection to this network
i spoke to 3 just incase its their end but they insist its nothing to do with their sim and is my phone thats the problem.
this is a sim only contract by the way the phone did not come from 3.
so u hav no signal??
imei may got reseted..
flash stock rom an c....
jus my sugettion wen in xda don float get registered
i have no signal or at best its extremely poor,just enough to scan for a network.
what do you mean imei may have been reset? the imei is the same as it was originally.
and ive flashed lots of stock roms and had no luck as of yet.
just tried android 2.3.5
Baseband 19100XXKI4
Kernel 19100XXKI4
Build gingernuts XXKI$
and its exactly the same :S
think ill just take the dog for a walk to the pub and see if theres an answer at the bottom of any pint glasses
IMEI correct YES ''
3 uk modem ???
Should be on xda I9100_radio_NELP2_CWM
network have you entered the network settings ???

so is ur prblm solved did u enter settings as jje said,,,,if ur phone is working fine now,then post
no my problem is not solved however i have some updates after driving around the area (going to the pub)
ive not changed any network setting as i see nothing there to change.
i managed to get a few signal bars and searched for available networks,3 was ther,when i selected it i got this message:
unable to change networks while data service is in use.stop using current data service and select another available network?
i said ` ok`
...registering on 3...
...registered on 3 network.
after this i was able to make a call.
i noted some info at this point incase it has any relevance :
Signal bars: 2
signal strength -109 dbm 2 asu
Mobile network type:9
service state: in service
network:3
phone number : unknown
this happened in one spot on a 1 mile journey.
and now im back at home the signal is back to nothing.
the 3 signal in this area is normally pretty good so something isnt right
the info now is:
Signal bars 0 - 1
signal strength -111 1 asu
Mobile network type: unknown:0
network: unknown
service state: out of service
mobile number:unknown
ive always had a good signal at home and for all of the journey i just made but now it seems to only pick up in a very limited spot.
ive not entered any network settings at all,like i said theres not much i can see that needs changing?
thanks for your input guys its really appreciated.
I don't know if its your issue,but I had several phones on 3 which all had awful signal strength- I just changed to a different network.
Sent from my GT-I9100 using XDA
3 isnt the problem here,everything was fine until i started fixing things that arent broke, and im old enough to know better :S
ive been with 3 for as long as i can remember with lots of different phones and never had any signal problems where i live up until now.
still unsolved
Weird. I have exactly the same problem. except Im on irish network meteor. same symptoms. ben on ics for ages, flashed a cm9 rom. nothing unusual,bam. no signal or very little.
try flashing NEKF2 or NELP3 modem
I have issues with 3 UK too, mainly because I like having the option to switch back to 2G to 3G to H, but 3 doesn't like the idea of GPRS so that's out the equation Plus, the network is pretty piss poor. I'm looking for a better modem, in all hope.
Baseband: XXLPW. Running ICS 4.0.3
I got a SGH T989 and got it unlocked for use in India..worked great for 2 months and then i rooted,flashed AOKP jellybean using CWM....after that, worked great for 1 month... Now the problem is that.....
My phone shows full signal and in the "about phone" menu,the signal strength is -100dBm BUT i cannot make calls and i'm out of coverage area for others.. The weird thing is that this happens only at certain spots (unfortunately, my workplace)...the device works just fine in other places...i ruled out a network issue coz my sim is good in other phones at the problem zones.
I tried another network's sim and it had call drop issues....the call would get disconnected after a few minutes and the duration of the call wasn't constant....this was also when the phone showed signal strength of around -100dBm. I had used this network before and it was working good with the phone..
I tried a master reset, complete system format in CWM recovery, reverted back to stock rom using odin, changed radios (UVLE1,UVLH1 and UVLI1)....nothing has worked so far.
There was no external injury or water damage to the phone, i didn't install any app outside of the play store and i use genuine charger for my phone.
I love my phone too much to let go....please gimme a solution
Thanks!!
Hi All,
I've been a visitor to XDA for couple years now and greatly appreciate the people who post here who have helped me to custom my Galaxy SI, SII & SIII with generally no issues. I've had my SIII for about a year and a half now running CWM & CF root with either Darky's ROM or a Nightly build of Cyanogen Mod.
Since moving to a new house (few weeks ago) the signal on my handset drops as I make/receive calls. I assumed initially it was just the signal in the area and as I had been running a non-stable build I flashed a full release to be certain. I chose Delta ROM initially but have since flashed Darky's, Delta (again), Cyanogenmod (Nightly, stable, unofficial 11), multiple different Modems when running CM (area specific, model specific & the emergency one for EFSv2) and followed the guide to reset to stock (unroot, official recovery, reset counter & stock ROM) none of which has helped.
To be specific, I can use the Wi-Fi, 3G, send texts and use apps which use 3G to send texts (MightText); which to me (Novice at this stuff) seems to indicate that the 2G & 3G functions of the phone work. Yet still as I make a call, or receive one, I do not hear ringing, person speaking or any form of buzzing; this applies if I use the phone as normal, the speaker phone or a handsfree set.
Roughly 30 seconds into the call the network drops (signal bars go empty), the phone call displays 'Out of Network Area' or some such, the call ends and the phone returns to the home screen where roughly a minute later the network reconnects and I can use 3G again, send texts etc. as above, except still cannot make calls.
I don't know if it has any bearings but on Cyanogenmod the time before the network drops is around the 45-60 seconds mark, all other ROMs disconnect at around the 30 second mark and my GF has an S4, on O2 as well, and the signal on her phone has been temperamental lately, but has not shown the same problem, she is running Stock firmware without root etc.
If I had to replace a component instead of sending off to service centre, how difficult would that be?
Thank you in advanced,
Martin
If it still has the same issue with full stock rom then it's hardware, motherboard/antenna etc. Unless you often dismantle and successfully reassemble mobile phones it isn't recommended to try yourself.
Samsung give two year limited warranty, worth trying with service centre after resetting counter.

Yeee I had a look around alot of forums for similar issues but could only find posts where there was no signal at all or playing up due to modem etc.
In desperation I opened dialogue with an O2 Guru who said hardware, but just seemed very coincidental to have happened when we moved =/
Thank you for confirming though worth a shot!

You moved so you may not have the same signal strength .
You need to work out if it is the network or the phone .
Try another phone in your location with your sim .
Test your phone next to an O2 mast .
Wipe phone flash stock rom for your network and test .

The O2 Guru I spoke with said the signal at my home address should be OK, my GF has an S4 on O2 and although a bit crackly, her phone functions works and I have my SIM in a temp phone, a Galaxy Ace, which has also been working fine in the area.
It's a good idea to test closer to a mast, I don't know where the nearest one is to be honest, is there anywhere I can find this out?
My phone is currently flashed back to stock, that's recovery, ROM, counter, modem (I believe) etc. followed this guide to do so:

What boggles me is that the phone is able to send texts, use 3g and search for different networks to 'register' etc. but the phone call disconnects. I would have thought that the same component which connects to network to send texts would connect to make calls? Is it possible that where I am in a weak signal area, the phone has damaged the component by increasing the gain by too much/for too long? If so is that because there was custom software or would the settings for this component be the same as stock?
Bit concerned about sending it off and the possible questions/costs associated with this sort of thing. This is the first time I've had a phone which has a hardware fault, all the other times a phone has played up its usually due to the software which can be flashed using any number of methods found on this site.
What a frustration, sorry to ask so many questions, just at a bit of a loss as to what to do with it now!
Thanks,
Martin
In a weak signal area your phone has to output 10x the signal strength to maintain voice call, which it probably didn't have to before. Data and text use much less power, hence why they still work. To test just find somewhere with full bars strength, maximum ASU value in settings, about, status.
It sounds like a high resistance gap somewhere, it gets hotter during use until it breaks the connection - then cools to join again.
Just make sure you describe the fault correctly and it should be repaired.
