My Galaxy S 3 got a problem. When I choose the network only wcdma, no signal appear; if I choose only GSM, the signal is good; WCDMA/GSM, some seconds no signal and some seconds has. I have updated some firmware, but all is the same. I do not know what happens, and can some body help me?
Looks like your provider has rubbish 3G coverage
Try different simcard on network with good 3G/2G and then see what happens

No, other's telepohone has a good 3G signal except for mine.
Hmmmm... Try different modem, if still nothing than your 3G antenna can be faulty or disconnected...

Thank you but i have already tried different modem but it;s still like that, no signal with WCDMA
Service centre or the phone vendor is your next step .

SOME CSC dedicated for SOME networks can have SOME effects on SOME devices, being useful for SOME users in SOME countries...

yes only useful to some users, not me. I failed again. So what's wrong with my galaxy s3, it's a hardware porbelm or software problem?
Speak to your network first and check its coverage maps .

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.

lets try to find solution together... i am totally on different network, Etisalat of UAE.
up to now, going to GSM Mode solves this issue but i loose "fast speed network"
I tried GSM Mode only but the issue is still the same.
Actually i'm on:
PDA: I9100XWKE7
PHONE: I9100XXKE4
CSC: I9100XEUKD1

i am currently on the same build... in fact i tried all previous builds and even KF1 & KF4 but all were the same
I have this problem with my WiFi network.
The title on this thread doesnt say which kind of network you are talking about.
Data network and phone, wifi network works perfectly.

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.

exactly... thats what happens to me too. what do you think is the solution?
What is even worse is sometimes in the middle of a conversation it goes to flight mode!!!!!!!!!!!!!!!!

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 installed the PACman 20.1.0 ROM for i9300 some days back along with Yank555 v1.5b kernel. Till yesterday, I had no problems with the ROM. Worked smooth as butter.
I usually use the internet on 2G/Edge and switch to 3G only when I need to browse. But since yesterday, whenever I switch to 3G, I lose total network coverage. However, on switching back to 2G, the network returns and I can use edge.
I have scoured the internet for a solution but could not find one. There is also no dedicated thread for PACman in the Q&A section.
Anyone know a solution?

Is your APN listed and are the settings correct? Otherwise restore a cwm backup to get 3G working again (assuming you made one).

APN settings are predefined by the carrier. I got EDGE running anyway. What usually happens is if there is no 3G coverage, it switches to EDGE and once the coverage is available, it switches back to 3G. The last part isn't happening.
Could this be a carrier fault? I have spoken to the Customer Care but they seem to find no problem.

Power down the phone and remove and insert the simcard, sometimes that helps.

Look on you carriers`s webpage for the apn settings, delete the current apn you`re using and create a new one with the settings from the webpage.
If that doesn`t help maybe a new simcard fixes your problem

Hi all, I am having a problem with signal strenght on my i9100. When the phone is on a table the signal is about 3 lines, at 70% of strenght but when i hold it in my hand it looses reception and it says only emergency calls, I've tried everything, changing the software, official/custom, tried different SIM card, trying 3G/GSM, nothing, I've even changed the antenna, same problem again, how can it be solved? Can it be a problem in motherboard or?
The problem is just like on example video.
Please help!

My phone is locked on to VIP Croatia network, I've unlocked my phone using paid GalaxSim unlock on T-Mobile Croatia, the signal was weak just like on VIP network, then i flashed I9100XWLSD_I9100CROLSB_CRO which is for T-Mobile Croatia and signal was also weak, then i flashed I9100XWLSD_I9100VIPLSC_VIP for VIP network and signal is also weak, I tried both, VIP and T-Mobile SIM cards, on both of them is signal weak.
Could you please recommend me a modem, because I'm new to S2 and don't know which modem will be good.
Tnx in advance!

Ok, tnx, I will try to flash this modem, and will call back the results.

Or just search for veyka modem list as theres loads there.
None of that helped, I'll try to change the RT module, the one with micro usb, maybe is something on it making problem, i have a spare from other i9100 on wich is microusb not working but antena works so I'll try with that and report.
Hello!
I have problem.
I have galaxy S2 with stock rom, and the phone comes from UK. I have pretty bad mobile network signal in Latvia. Comparing to some other S2 phone, it had better signal strength.
My guess would be, that some Frequency's are different. I couldnt find which phone builds are meant for which countrys, and couldnt get list of supported Frequencies.
My phone build nr. is "JZ054K.I9100XWLSD".
Try different modems

I meant that you're right, OP needs to flash a different modem.
I've added that he/she needs to flash the same modem as on the S2 with the good reception.
O ok cool. Sign may not be as good if on a different network or maybe it's his network that's slower than his mates network. But yes good advice and open should do that :thumbup:

Hey. Any progress on that problem? I have the same issue. My phone works only on 4G. Or 3G if signal is strong. I have problem at home where 4G and 3G signal is weak. Most of the time I have no network.
