Try changing to a different phone on your line(esn swap), or call customer service and ask them to reset your DMU.
Hi guys I got a big problem, hope u can help.
I have this phone for a couple month already, when I was still running stock I discovered my cell phone would tell me I got no signal. Turning on air plane mode and then turning it off didn't help to get back signal. So I had to turn off the phone and turn it back on to get back my signal. Problem is I never know when it happens until my wife asks me y my cell phone is switched off. So I went ahead rooting it and I flashed a rom on it. But problem isn't gone. I still lose signal but on this rom it shows me full bars, only cannot make phone calls,SMS,and gprs. Tells me no network or no sim card is inserted. I always have to turn off and turn it back on. Now that it is rooted with whatever firmware I can't bring it to Samsung store to fix
please any suggestions?

Maybe you could try another sim card. Just a thought

Sounds more like a carrier problem. I'd ring them. Check your APN settings too.
Hi,
I have similar issues. Doesn't matter where I am and how good the network coverage is on all other phones around, my SGS2 keeps changing the coverage icon, from 1 to 4 "sticks" of indicator, or to no coverage state (crossed circle icon).
Sometimes the wireless is not working also, or juts gets very weak signal, though the signal is good on other devices near by.
When I try to turn data network (by pressing the power button and selecting data network activated from the pop up) sometimes it's not even showing the data network icon in the system bar (top of the screen), it's like being disabled data network or something.
I can answer a call and stay on conversation for no longer than a minute, then the signal goes dead and the phone just freezes, when I try to tap red button to end the call - no reaction, I have to turn the phone off.
When I try to make a call it just says "dialling" for ages with no result and eventually the phone freezes, so I have to turn it off and back on again.
Sometimes it turns off itself though the battery was showing almost full icon.
I went to O2 store, they gave me new SIM card, but it didn't help, so it's not a SIM issue.
I did a full (hard) reset - no help.
The guy from the O2 store told me, that I can root my phone, and I will not loose the warranty (I purchased the phone only one month ago), only thing I need to do is to revert it back to original state before bringing it (in case of hardware replacement).
But if it is not a software issue at all, so what's the point of rooting and having all the hustle, then reverting, etc... Can there be some hardware issues? I don't know: antenna, RAM, CPU, whatever???
I hope I've explained everything clearly enough. Any ideas would be appreciated. Thanks in advance.
What firmware are you on have you tried to Upgrade via KIES .
Rooting will void warranty and will also increase the custom rom counter from zero . Yes they can be reset in most cases .
Rooting will not fix anything at all .
Network is first check are you getting problems at all locations .
When in the O2 store did they check the signal ???
Choice return to service centre
Flash a stock Samsung firmware via XDA possible to also try a different modem via XDA .
None of these will fix hardware problem .
Personally i would factory reset the phone and check all the network details are correct on the phone then return to service .

when you have this problem check if you have an imei (*#06#) if the response is empty then you have to reflash...
Hi all again,
after posting my previous post I phoned my friend during a lunch break at work. We had a quite long conversation and the quality was perfect. Then on my way home I turned on data network and enabled GPS (LOL), then launched navigation app and it took me home without any bugs (I know my way home though I did it only for phone testing).
Now back home, sitting in my room and my SGS2 starts to fool around again: unable to turn on data network, poor wireless signal (but it's good on my PC), the network coverage icon turns into "no signal" state and comes back to normal again all by itself.
I will definitely test my phone again tomorrow on my way to work and in the office. But it seems like there's something wrong with the place that I live. I've moved in recently and must admit, that all my problems with the phone started only then. And I didn't noticed any bugs while at work or anywhere down town.
Meanwhile is there any way to scan/check the area around my flat? Maybe there's something wrong with the in house router, or maybe to many routers in surrounding flats, or some other equipment/hardware things messing up, or just a mysterious house blocking O2 network and hacking the phone LOL??
The only strange thing is that I'm having not just a network/coverage/wireless issues, but the phone freezes, battery full-empty-full-empty status randomly, etc...
BTW, my details:
Model: GT-I9100 (not a I9100G)
PDA: XWKJ1
PHONE: XXKI4
CSC: O2UKJ1
Android version: 2.3.5
Updated via KIES about a month ago, was working good until now. KIES says that at the moment I have the latest firmware.

Hi there everyone.
I have a Samsung Galaxy SII. I live in Australia, have an unbranded phone, and am currently with TPG as my phone provider.
I have been experiencing these problems for a long time, and after trying to figure out what's wrong with it, it's time to ask for help. Haha.
These problems started after I flashed a new modem after installing a ROM. Previous to flashing, the reception had been fine. After flashing the ROM, and not the modem, my reception was still as good as it was when I first received the phone. However, after flashing a new modem, the reception dropped significally. Where my brother also with a i9100 could receive full bars of HSPA/3G, I could only receive 2/3 bars of G. Where he would have 3 bars of G (in our house, it has this stupid insulation that really nerfs reception), I would receive absolutely no reception.
I have tried countless modems (pretty much ever modem since K13, testing for reception, but never have much luck, maybe a 1 bar fluctuation up/down).
Do you have any ideas what could be wrong? How I could fix it? Thanks very much.
find the modem your brother have ,download it from the intratech and flash it
have you tried KE7?
I got a good expereance with this on Data speed, but I dont know about reception strenght.
go through discussions of this thread http://forum.xda-developers.com/showthread.php?t=1131950
He hasn't updated for a while, and is using the K13 modem. I have tried it, along with the K14, and KE7 already.
do a factory reset without the sim and sd card....
I tried factory resetting without the SD and Sim card, but it still didn't work.
Any other ideas? Haha.
Do you have i9100 or i9100t

The international i9100. The phone was originally bought from Vodafone, then unlocked with a code.
Mines vodafone australia and its a i9100t.have you tryed a t modem
Sent from my GT-I9100 using xda premium
I haven't, maybe that's the next thing I'll try. But does your box say i9100, or i9100t? Mine just says i9100. Haha.
Edit: Omggg I love you. Hahaha. I flashed a T-modem, and now I'm getting full reception. Thanks somuch!

Hey,
I was playing around with a few Custom ROMS today, and my mobile data stopped working. The APN settings are correct. I have flashed multiple ROMS but no luck. Even stock ICS ROM. I think I have the wrong modem/baseband combination.
My phone show H+ or 3G icon, but as soon as I try to use the internet, it vanishes. Wifi works fine.
Any ideas?
Seems like incorrect apn.. but you already say it's correct..
Try to Flash the stock modem..

Yes the APN is correct.
Could someone possibly tell me which firmware I should flash? I purchased my phone from Pakistan, but I'm not sure which region it is for. Will that make a difference?
Something happening with this phone. I had the same issue a few weeks later.
I tryed almost every modem available unsuccessful. Just my local carier can solve. I didn't known what they did, but solved until now.
Although your apn settings may be correct, they may need updating.
This sometimes happes in the uk.
Maybe if you tried deleting the apn settings out and then ringing your carrier network up, and asking them to sent your correct apn settings to your phone, maybe this could help.
Its not a dead cerainty but always got to be worth a shot mate
If you dont like the THANKS button then just click it to make it dissappear

Had the same issue with my GS3 (I9300) after switching from those Straight Talk Bastards to AT&T:
Whereas Straight Talk simply f*cked up b/c of a collapse of their data network, so I assume (with nobody at ST saying a word for 2 days, of course.. ), it turned out that AT&T actually had deleted my new account - by mistake - after just one week of 'happy browsing'.
A trip to the local AT&T store solved the mystery and got me up & running again.
Unfortunately, though, it took the AT&T folks a while to figure it out, as they are not used to unbranded/international/ unlocked phones wanting to join their US network. (Don't even try to solve this over the phone, if you have a choice).
Kudos to the AT&T staff, though, as they got the problem resolved eventually. It definitely helped a great deal that my phone had been working just fine on their network just a week ago, so I was able to stand my ground and insist that the problem was at their end.
One of the reps - apparently without a clue - tried to tell me all sorts of BS, e.g. that the I9300 would not work on AT&T; that some Samsung phones supposedly don't work with their network... bla bla blub blub...
Fortunately, I knew better and told him so. Otherwise, he may have successfully gotten rid of me; making me search for the problem someplace else (a.k.a. giving me the run-around or making me chase my tail, etc. :banghead: )
Thanks to xda (and the Internet), however, I had all the knowledge necessary to make sure they get it back to work. Now I'm browsing the web again with 7Mbps Down/3Mbps Up speeds, using AT&T's really fast HSPA+ network here in the Chicago Northern Suburbs (close to O'Hare)... Yay!
Good Luck with finding the problem with your data loss issue!! :thumbup:
P.S.: Let me know if you need my APN settings; just for comparison (.. in case you are in the US, too).
Cheers,
AA

Before I get in to details about my conundrum, let me explain that I have experience with flashing all sorts of stuff with HTC phones, so lay it on me.
Now for what im running.
Rogers i717r, with rogers 4.0.4 on Wind Mobile. Voice/data works...ish
I purchased the phone from a shoddy cellphone liquidator (i know, i know, but I NEEDED a phone)
I poked around in the phone for a bit, the flash counter was at 6, and ICS blaze.zip was on the sd card.
The Baseband is Unknown.
I Have rooted it.
always shows 4 bars and wont let calls go through sometimes in 3g mode.
ive searched though this forum for a week, i see alot of back and forth.
Can i install a ICS modem on jb?
does the flash counter have a limit?
should i just stick with ICS stock and try modems?
get me running in tiptop shape, and i shall donate.

I am not on Rogers, but I think there are many that have great success with Blaze running a JB rom. Trying different modems will have no ill effects, it will either work or it wont. There are many on Rogers that carry a pocket full of modems with them and swap them out depending on the area.
As for the flash limit, if there was one, im sure I broke it long ago.

Im not on rogers either, i need this phone to function on AWS.(wind mobile)
I fiddled around with the APN, and put as one setting instead of separating Internet and mms, it tends to wake up the "4g" faster.
so yeah, i should be fine flashing cyanogen 10.0 with the blazeICS modem? to be connected to a aws network.
