What is your base bad version/radio modem? What version of android are you on, are you on a custom rom or kernel, are you rooted, are you completely stock form the manufacture and who is your cellular provider?
Go to your settings and then to about phone and you can take a screen shot and upload it. or type your results?
Make sure to delete from the screen shot your mac address you DO not want or need to share that with any one.
Has your phone been dropped, damaged or water damage. are you the original owner or was the phone used before you got it?
I was having issues on mine after installing CM12.1 (android 5.1.x) while using a GSM carrier (t-mobile); in my case it was calls not ringing in, and inability to end a call. If you're not on a 5..x rom, my solution probably won't help (and may cause more issues). My solution is here:

i notice that my phone have problem of losing connections (phone signal) quite often which causes the phone cant make or receive call. i usually go outstations and everytime when i travel i have this problem. i thought it was the problem from the android 1.6 but after updating to android 2.1 through the SE website the problem is still there. recently i end up with the conclusion that my phone have problem with GSM signal, whenever i go to outstation where there is no 3g/WCDMA in the area but suppose to have the GSM signal i got this problem. please bear in mind that i have change and tried the setting for WCDMA ONLY,GSM ONLY & WCDMA/GSM PREFERED but the problem still persist, and please bear in mind i have tested with my other phone and it works fine at those places. please advise if this is the problem of the phone itself or just the setting of my phone. Tq
Exactly same case here,losing signal without no reason.Only one time I saw all 4 bars.Other phones works just fine.OS updated to 2.1,problem remains same,and that also affects to battery duration.
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.

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.

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

@Iznee
i dont think changing the phone might be the issue, i had the same issue on IP4... it might be solved with future radios/ roms...
Received my SGS2 on 29th June and ever since it start having emergency call syndrome (out of blue not receiving any network signal).only after reset, it regain signal and same story goes on till date.
To overcome this prob,i tried these:
- factory reset 3 times
- manually choose telco/network carrier
- update/flash firmware (stock XWKF1 -> XWKF3)
so for these only reduce problem's rate to occur.PLease,help anyone?
Is your sim card active ?
Hi
I have the same problem as yours (i thought i am the only one having this)...out of the blue the phone changes to the emergency calls Only status....
it is very annoying specially when you are expecting an important phone call and you discover that the phone cannot receive calls
it became a habit of mine to keep checking my phone every once and a while, and when spotted i restart my phone and this brings the phone back to normal (Normal for a day or two of course).
Can anybody help with this?
SGS2 GT-I9100, Android: 2.3.3, Build: JHKG2
First of all I would download a newer firmware. If that doesn't fix it you should probably just return it to Samsung for replacement/repair.
Actually i have flashed this Israeli ROM (it is an Orange official but leaked ROM) about a month or so and it supports Arabic, English & Russian (exactly what i need) that i have no complains about so far except this emergency Calls issue and i am not so fund of rooting etc so i don't know where i can find another ROM (official not cooked ) that have the same languages supported.

What is your signal strength when it changes to emergency only? Mine does that during very weak signal, I found it's because it can only receive GPRS singal which is from another carrier when my own (HSPA) can't establish connection.

frankly i didn't check or notice such thing, but the moment i installed my latest ROM (GB/JHKG2) i have noticed that the signal strength is very week especially indoors.
thinking off and analyzing this situation i have a confident opinion that the problem i am facing is related to the ROM i am using (GB/JHKG2).
i am thinking of flashing a different Kernel to this ROM and see what will happen

When you installed a different rom did you flash back to your original telcos baseband? This makes an enormous difference to signal strength.

sorry LuvinN1 i am new to such terminologies and i have no idea about what you mean of telcos base band
I have flashed another kernel and guess what? ....the problem is solved ;-)

Is anyone else experiencing network problems with Samsung Alpha 850F, my phone is dropping calls and network. It reconnects after few seconds but it is really annoying.
I got latest firmware: G850FXXU1BOA2, changing network setting only to GSM doesn't help much, I have tried with different sim card and I still get same result. Alpha is not bought from provider but in retail store and it was rooted, so I guess I cannot send it to warranty.
WiFi connection is stable and I don't have any problems with it.
Anyone has suggestion what can be done?

Hello,
As far as I'm concerned, the same thing is with everyones phone (signal strength is always at approximately ~-103 dBm) but I've never experienced such an issue with dropping calls nor network itself. Nothing you can do about it, everyone is experiencing this issue.
Best regards,
James
I also see the signal drops but never experienced problems with phone calls. I think it depends on the provider too, if you got a cheap poor signal provider you're more likely to face these call drops.

My friend had same problrm with S5 and he fixed it with factory restoring defaults and changing CSC to his region. I'm waiting for android 5.0 so I can that also.

Hi. My Galaxy S3 i9300 drops network connection from time to time for no reason. I have a full coverage in the city, all the signal bars are full, however it drops the signal sometimes and reconnects again. That's very annoying while talking on the phone. What I tried so far:
Clear cache
Hard reset
Changed to another custom stock rom
Installed another kernel and modem driver
All these makes me think that it's a hardware issue. Anyone who knows what it might be and how can I fix it? I have a hot air gun and I am able to replace parts if one knows which part might be faulty on the motherboard. Thanks!
*#*#4636#*#* and change to gsm only (mobile network will not work, changes work untill reboot). Use that if johnny_GSR post dont work for you.
Hello, i lost my antenna signal and i can´t get it back. I´m using CM13 snapshot 20.08.
Yesterday all was working fine but now the signal is lost. I reinstalled the rom clean but still the same problem. Any indears what can be the problem?

Your baseband version is ok or unknown? Maybe you need to reflash only modem

i checked and baseband isn´t unkown. Thanks for your reply. I think it´s a hardware defect.
