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..

sorry guys : ( its not the fact causing network error.. i got a drop in signal after 2 1/2 days..

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.

Dropped Connection to Network Problem

my phone will drop connection and then not reconnect. no voice, no data. (wifi still works)
what I've tried:
1. Different radios/firmware
2. different roms
3. different preferred network types
4. switching airplane mode on and off
what I haven't tried:
1. different sim
2. calling tmobile for suggestions
What else could cause this problem?

it could be a hardware issue

Hello,
I have the same issue than you !
I am facing issues such as call drop and no 3G data connection in some area in my region since I have 5 signal bar and H letter displayed (HSDPA connection)...
I have found a workaround consisting in:
1 - Switching to GSM Only mode (2G Only)
2 - Desabling Mobile Data Connection
Then it works, I can pass and receive voice call ...
Regards,
Nino

I'm new to the Sensation and having the exact same issue.
Followed the stickies in the Dev section to S-OFF, root and bypass SIM lock and then once the SIM card is inserted I get only GSM and no data.
If you use *#*#4636#*#* in the Dialer and go to Phone Information do you notice that it always switches to WCDMA preferred? I change to GSM/CDMA auto PRL like all my other Android devices (on Rogers Wireless) and it disconnects, reconnects but only for GSM and no data. It sometimes says it's connected to EDGE or HSPA but no icon at the top right and then it reverts back to GSM.
I have also tried flashing virtually every firmware, ensuring that the radio and RILs match (I had an HTC Desire Z so the HTC phones are not new to me entirely). I don't know what else to do. I tried a Bell SIM card and tried all of the same options to no avail.
I really hope someone can figure this out. I don't want to have destroyed a phone that I just bought for my wife. Her Atrix broke and I purchased that outright as well, so this is really killing my wallet. I've been through about 10 Android devices and I wouldn't say I'm a newb, but I really do feel like one right now. This sucks!

Get a new sim from tmo if it's over 2 phones old.

Exactly. Although I got it before I saw your post, you were completely correct.

definitely try a new sim card.

I've tried 5 different SIMs now. It's not a SIM issue. The other poster has a different issue but mine's identical to the OP's.

Haha yup, thanks though! I know, it could always be something so tiny and stupid too, eh.
Someone posted in my own thread and said to do the following. Will by trying it once I get home. Could the OP please try this and report back? I sure hope it works!

first open the dialer
Type *#*#4636#*#*
select phone info
look for the only drop down box - hit it - choose wcdma prefered - hit back 3 times
Go to menu settings woreless and networks
hit mobile network - it need to be ticked
hit mobile networkS hit APN or Access point names - hit the menu button - choose reset to defaults
go back to mobile networks - choose network mode, select wcdma only - look for the 3G or h sign when it shows go back and choose gsm/wcdma auto
if that fails do a manual net work selection - choose your networks 3G option

I did try every setting in there. The new sim card fixed it! So I guess our problems are different.

Rom data integreation

hey guys i recently flashed a new rom thats meant for another phone but is backward compatible with my phone, but the data connection stays on edge and on the previous rom on the same location i get H or even H+ at 8mpbs speeds which is average for Blu life play on my network. Now i tried changing the modem and even asked others for help but no help arose, what do you guys suggest?

ok so it works on sim 1 but not sim 2 slot

[Completed] Please help me with my network problems on you yureka plus

Hello guys,
I have a you yureka plus phone which I bought a week ago. I'm facing network problems with it since the time II switched it on. I am not able to get network coverage and therefore very less Internet speed in my home whereas my older phone gets amazing coverage and very high internet speed.
I have contacted the sim card operator and they weren't able to help.
I tried almost all possible ways to get rid of the problem.
I tried the *#*#4636#*#* thing.
I tried changing different apns.
Rooted my phone and tried different custom ROMs and kernals.
So far global ROM miui v8 is the best one as it gives network bars but the internet speed is stilp very low compared to the other phone.
I flashed a different modem file found here in xda but that also didn't work.
I'm out of ideas and I'd really appreciate any help.
Sim cards- jio and tata DoCoMo
Current ROM - global miui v8 based on android 5.1.1
Kernal - velocity v10.3
Thank you.

Hi !
This seems to be a device specific issue , maybe your network doesn`t match the device basebands , try changing them from settings/prefered network type and also get in tuch with your provider about this
Cheers !

i tried all the options in the preferred network type with no success. my provider said there's something wrong with phone's software and he couldn't help with that

Are you sure that the phone supports your carriers bands ? You may find that you are only able to get 3g or only have one or two of the bands that your carrier uses

Sawdoctor

I'm sure it supports 4g, because I get good 4g speed in my workplace. I'm having this problem only in certain areas like my home and college. How do i check the exact bandwidth capabilities of my phone?

One Plus 6 Avengers Edition - India - Issue with 4g signal with Vodafone

Hi All,
I am using the Avengers Edition, India Version, with Vodafone in Bangalore, India.
The phone was holding good 4g signal.
I am not sure, but after the latest update to 5.1.8, the vodafone sim, in slot 1, seems to lose signal for few hours. it comes back on a restart or recycling airplane mode.
Also, the phone on fresh restart or switch back/forth between airplane mode, holds good 4g signal but falls back to 3g (H/H+) after about 10 minutes.
On reboot and recycle of airplane mode, at times 4g comes back but again falls back to H/H+.
All the while, slot 2 has a Jio sim which has good 4g signal and never loses signa.
Is anyone else experiencing such kind of issue.
I am not sure if it is the phone or it could be vodafone as well.
I am going to run few tests swapping the sims between the slots 1 and 2 and also try using the vodafone sim on another 4g phone and report back.
In the meanwhile, if anyone is encountering such issues on this phone, it would be great if you could reply on this thread.
Thanks in Advance.

I'm facing the same problem

Thanks for replying.
I put the vodafone sim in slot 2 and it seems to be working fine.
Also, Jio was in slot 1 and it never lost the signal.
I guess network then is not the culprit.
Since you are also facing, it could be a software issue as it has happened after 5.1.8 only.
Hopefully a bug that will be fixed in future then.
Any other helpful responses would be appreciated.
Thanks again.

Well I just put Vodafone back to 2g only and it seems to be working fine
And my guess is it has something to do with the merger of idea and Vodafone in India . They seem to be fixing it up .
I really hope they fix it ASAP!! ( not OnePlus I'm talking about Vodafone fixing it )

I'm unable to get Volte services on Vodafone 4g, while it is working fine for jio and Airtel. Despite of having Volte services it still switches to 3g... And I have the normal version of the phone.
