Emergency Calls Only!

Hi guys
This is the first time ever I am trying an android phone out coming from an iPhone 4.
So basically I got my nexus s yesterday it said it was on vodafone but I understand the nexus s is fully unlocked. Anyway yesterday I put in my o2 sim and it worked out the box making calls etc. I rooted it and everything was fine. This morning I used the gps for a trip to work it worked perfectly. I could connect to the 3G network etc.
When I came home in the evening I tried to make a call and it said emergency calls only but it doesn't let me make any calls! I have hard reset it. Tried different roms. Erased cache etc etc. Still nothing. I called o2 support and they said from their end my sim is fine and no problem with it there is no lock etc.
If I go into the diagnostic tool thing *#*#4636#*#* it says the following
Signal strength -107 dbm 7asu
Gsm service: emergency calls only
Gsm disconnects: state:dcinactivestate disconnected with last try at 12:59am fail because no error
I have no clue what's wrong please help!

nevermind, missed that you had done that

Some one please solve this damn issue......it is more spread in India.......tried all baseband updates but still......driving me crazy

Same problem here.

Hope may fix!..under testing..Emergency calls only!!
I was so much annoyed with this so called network drop issue 'emergency calls only' which is appearing on my moblie every now and then and while on important calls..suddenly cutdown due to network loss.
im not a techy geek to go into kernels and rewrite some of the scripts ..etc..
so i may sound silly..but pls try it out..its working for me for last 2 days without drop..may be bcoz of wat i did or may be simply dont knw still testing..so i thought to share this across and see wat others experience..
the actual thing wat i did find is that there is some .005 mm gap over the sim in sim slot so i felt it may be a cause of some not contact of sim with the slot..in some micro levels..
so i introduced a paper above the sim while inserting sim in slot then it becom tight enough to stay its in contact all times..
its simple.. but u people hv to say weather its bcoz of this it works ..
Thanks Ram..

Same issue!
hey guys,
I am facing a similar issue.
I picked up my Nexus S (unlocked) running on 4.03 from UK, but using it now in India.
Baseband version - I9023XXKI1
Kernel version - 3.0.8-ga178ab4
Build number - soju-userdebug 4.0.3 IML69C 235871 test-keys
When I use any SIM here (Airtel/Vodafone), it is getting into Emergency mode. But strangely the GPRS service works. I am able to browse, stream, email etc. I dont understand how GPRS services are working when GSM isnt?
I am unable to use my new phone! Can anyone please shed some light here...

My nexus does this also, I've only found trying different radios to help but not eliminate the problem. Also when searching for networks, manually selecting your carrier instead of having it on automatic also helped.

I had this problem the other day. I was on emergency calls only, and AT&T said it was due to an antenna outage. Then I told them my wifes phone was working.. ended up at AT&T store, no luck, etc, etc.. To put an abbreviated story of my night of pain.
I tried a ton of different radios, all would not connect to 3g or make phone calls. Until I installed UCKF1 (New Version) from the [RADIO/GUIDE/TWEAK]Radio JK1,JK8,KB1,KB2,KB3,KD1,KF1 & UCKD1,KE1,KF1 with HSPDA Tweak thread. I don't know what that radio file did, but it fixed it. And after that when I flashed other radios which were previously not working, they were working again.
I'm not sure what happened, but while this was going on radios I had used before like KB3 didn't work. Once I had UCKF1 (New Version) installed, I was then able to successfully go to any radio I tried.

[Q] [i9020A] Install I9020AUCKD1 baseband??

I decided to root my i9020a cuz I wanted to try the goodies. So I installed the CM7, but didn't quite like it, so then I decided to install this rom that is a kinda inbetween the stock and the CM7, but all of a sudden it died on me after a reboot I did after several days using the rom without problems.
So, I decided to install the stock rom from here and so I did. Ever since my phone doesn't connect to the 3G network and I checked with my carrier and I didn't go over my limit or anything, so I'm thinking maybe I screwed up the baseband or something.
So I tried this, but that didn't work. Tried directly doing to 2.3.4 and also first to 2.3.3. and then updating, still no 3G.
Currently my baseband reads: NO DGSXXKB3, but I remember that when I got my phone it used to read: I9020AUCKD1
How can I get back to I9020AUCKD1? Any ideas? Am I way off and it's not the baseband? Help? I'm really desperate now after hours of lurking around google and here
For 3G I need HSDPA 850 / 1900. I'm aware the phone supports 2100, but my country doesn't.
Thanks in advance

Dude - you are a life saver!!
I don't know why, but this morning I woke up with no cell reception - no phone calls, no data - on a day my son was sick and I had to call his school - I have no landline! lol. All it would say is "Rogers" in the available networks.
Got it figured out though, wiped the thing, stock 2.3.4 image, then with the settings you had above, bam, worked like a charm. Back on koodo.
Phew! Thanks again

[Q] S3 still unable to connect to networks in Honduras

I have tried absolutely everything possible that I can find here on the xda forum and elsewhere to get my Verizon Samsung S3 up and running on the Tigo network here in Honduras and have come to a dead end.
Android Version: 4.1.2
The phone has been rooted using a step by step thread I found on a blog called rootandunlock (which gives kudos to xda)
Build #: VRBMF1
I have the APN's set up and have gone through activating them but no matter what I do the phone just isn't recognizing the towers here. It does find towers for Claro HND but won't connect to it.
I don't know where to turn at this point, and really would love for this phone to be more than just a lonely paperweight

Same problem
I would love for some one to let us know what we could do!

I found a solution to this problem.. it just isn't really the solution I wanted to find sadly.
After rooting, flashing Omega rom, Clockwork, and going as far as to alternating the APN's to the networks here in Honduras the phone WILL make and receieve calls and texts on the TIGO network (I didn't try Claro), but it will NOT work for data. You can of course use wifi where ever you go, but it will not connect to the data network as far as i've been able to figure out.

From what I read on TIGO, they are using gsm only in Honduras now ( and shutdown cdma ). If this is correct I don't think that data will work on s3. Tonight I will do some more research and see if I can learn more.
But until then it maybe worth changing the network settings? To gsm or global.

Galaxy S7 LTE problem's

Hello from Bulgaria.Some one have had a problem with 4g network.Samsung S7 when he was lte \ 3g \ 2g after 30-40 minutes , scope disappears and receives a missed call notification.The problem gone after restart the device and after 30-40 minutes is same situation.If a phone is an 3g\2g no problems.
Sorry for my bad english.

Same here
My cousin bought an S7 Edge, but it had the same problems as listed. She then proceeded to change the phone, yet the other S7 Edge had the same problem. What could be the solution to this problem, and what caused it?

I change 3 phone 2 black and now give to me gold,for now i don't have a problem with the gold piece. Everything work fine.

We changed two gold ones, awaiting for the third. Problem seems to be persistent.

Hi!
Go to settings and find your APN-settings. Remove IPv6 and save it. Then everything should work fine.

I'm having the same problem. I'm sitting beside my friend with his ip6s+ and he's not having trouble connecting with the lte. just saying that this might not be just a network problem.

I've read about multiple people, including me having this issue, for some the APN IPv4 switch seems to work, but not for everyone. So what is this? Is it related to the phone hardware or software? Or is it a network problem? And will it be fixed? As this is starting to irritate me a bit..

Many People in my country (indonesia) is having similar problem. The signal somehow stuck in 3g. Forcing it to use LTE only using the app "4G LTE Switch) makes the signal gone, emergency only mode. Only a reboot would bring 4g back.
However it only acts up when using one specific mobile provider (telkomsel). Switching to my second sim, also by the same provider, didnt help. But if I switched to another provider, the problem doesnt happen.

Widespread issue in Germany as well. It's carrier independent. Had to exchange one unit. The new S7 Edge I got works fine so far, but has a pink hue on the display. Samsung QA! -.-

Any solutions or updates?

Solved?!
Hi,
I had the same problem in bulgaria with telenor.
Yesterday i got an update on my s7 edge to XXU1APCH and it seems to solve it.
This night it stayed connected. Normally i had the no service available in the morning.
Anybody else see the same?

Downloaded bulgarian firmware,, XXU1APC8 is the only one available. Tried to check for update, nothing yet to xxu1apch...
Update:
Emailed Indonesian Samsung Support, they came up with a temporary solution:
go to phone, dial *#9900#
select debug level disable/low
change to mid
wait for phone to reboot.
2 hours past no signal lost yet
update: 3rd hour signal gone again

hi,
has anyone found a solution for the problem above?
in my case I have really slow internet (mobile data) on 2,3 or 4G, it's like it freezes when I try to open a page
when I connect to 4G it maybe works for a second and then nothing else, it's like 2G, very slow (wifi works normal)
can it be hardware problem? I already cleared cache and reset the phone, but it's still the same..

At me the phone can not change back to 2G from LTE, if 3G network is unavailable.
If I use LTE/3G/2G option and somewhere is not 3G network I can't receive or make voice calls.
Phone only works with 3G/2G option in network mode.
But in this case I only can use edge if somewhere only 2G and 4G networks are available.
If I use LTE network, the phone doesn't receive incoming calls.

I bought my samsung s7 gold one month ago in Lebanon (Middle East). I faced exactly the same problem, I couldn't receive any phone calls. Went to the store and they told me to switch from LTE/4G to 3G. Now my phone is always on 3G and working ok so far. But I can't put it on 4G !!!

get new simcard will fixed problem

Hi, is there a solution to this?
got info that there is a patching from samsung for this issue but since i am using custom rom, i cannot confirm this.
anyone has any update?

Same problem! I'm from Mexico and i just bought my pink s7 Edge on sunday, i've been going everyday to the carrier store and yesterday they finally gave me another one but im having the same issue! I can't take it anymore i don't know what should I do Maybe all the pink ones have the same problem? They have already changed my SIM Card, i have tried with another one and it still happens

This sounds very similar to the LTE problem on the Nexus 6P I wonder if it is actually the same problem.

Problems with cellular reception since updating to Marshmellow on my S6 Duos

Hey everyone,
I've never really been into the whole flashing deal and I'm also pretty new to the xda-forums so pls don't hurt! :angel:
Anyway, so live in Germany and imported myself an S6 Dual Sim Version via Amazon, so that I could have Internet both there and at home in Ausria at all times. It had a Russian Baseband and CSC but it worked and filthy casual that I am I really didn't mind until now. It's a really weird issue, so sorry that the post turned out pretty long. I haven't found any similar common 6.0.1 Bugs, however I'm not even completely sure if it really is a problem of the updated OS anymore...
So here's the deal.
In Germany I got the prompt to update to Marshmellow 6.0.1 via OTA. Having heard mostly good things about it I downloaded it without really bothering too much about informing myself about any known issues with 6.0.x . After downloading it in Germany my Signal and Mobile Internet worked fine, however I did experience some battery drain in the following days and decided to initialise my phone via Samsung Smart Switch, as I had done with 5.1.1 when I first got the phone because it's cpu never went into sleep mode. Worked out fine then.
Well ever since I did the same thing with my S6 with 6.0.1 the whole dilemma started. Regularly, my phone will show 4G Signal Reception and even full bars, but I am not able to load a webpage or even be called by phone. Wifi works fine, when I have these outages. When I activate flymode and deactivate it again, my reception works again for a couple of minutes, however, the issue will return after 5-10 minutes. Usually even faster when I'm in a moving car or train.
When I switch SIM Cards I can be called on both, but I can't seem to connect to my mobile internet on the Austrian card (can't check on the mobile connection from the german card as roaming is locked by the provider). I went to my austrian network provider and had my sim card replaced, no change. I flashed DBT G920FXXU3DPCA Android 6.0.1 via Samsung Updates hoping that the right baseband would fix it - Nope.
Any of you guys have any other ideas? My last resort is flashing back to 5.1.1 stock. Trying to replace it through Amazon will probably be hard, because the KNOX Counter is tripped. It already was before I flashed 6.0.1, but that doesn't really matter to Amazon I guess. Also the bug is way to specific to replicate anyway, so I'd probably receive the same device back and I don't really know how I could prove via screenshot, etc...
If there's anything I can upload that would help, pls tell. Hoping somebody here might have an idea!

Having similar problems but also with wifi. Any advise appreciated

I have the same problem with cellular reception with my S6 duos G920F. My problem is only with sim slot 2 though. It seems to show full bars but when people call me they are getting me as unreachable.
