Aite Ive got two samsung vibrants. Bought them both new. Did the exact same thing on both to unlock them and make em work on AT&T.
One works perfect. The other one just says No service no matter what i do. I tried selecting the network manually but it says sim card doesnt support the network.
Next I tried the odin method to put the stock firmware back on. Rooted. Since my unlock codes werent present on my phone, i used the repair_nv_data fix to try and manually set the unlock code(what i did for the other vibrant), but still no luck. Still says no service when i put the sim in. Weird thing is data kinda works. It says no service but the 3G/EDGE icon keeps popping up and disappearing.
Any suggestions?
Search xda for "enabling the 850 band", id look but search is crap on the xda app. Its my understanding that it works better off of at&t towers with that enabled. Hope this helps.

I'm having the exact same problem, except I've had my phone for almost a year and just now got this problem. I can use data to browse, twitter, whatever; but can't make any calls. I tried my SIM card on another Vibrant and it works fine; tried another SIM on mine and still get "No Service". Any help will be greatly appreciated.

pls help!
Have you turned MOBILE DATA off via the power on/off menu .
jje
ive checked that too.
Go to Settings- Wireless and Network- Mobile Networks- Access Point Names and see if the APN is ticked or not or the correct APN is ticked.
everything is back to normal again,it connected to the internet, by itself . must be a random bug in the os
problem solved. peace
I have experienced the same thing with my phone, except that it shows "activated". After a while it just started working again.
I've had the phone for a couple of months now and everything has worked fine till now, a little bugs here and there but no issues. A few weeks back (on android 2.3.3) I was unable to make or receive calls, but surprisingly was able to make text messages. I tried everything, turning flight mode on/off; the phone on/off; etc. I was on the verge of contacting Samsung but then suddenly the thing started working once I came back home from the office.
There has been no problems till then but today suddenly (now on android 2.3.6) the outgoing calls no longer work, same for outgoing text message; but I still get incoming calls and messages.
Just to be sure that this wasn't a SIM or service issue, I tried changing SIM's (different SIM did not work on the phone) and used my SIM on different phone (where it worked).
Also 3G doesn't work as well, but connection here is spotty so I wouldn't trust that. The only message I see different on the 'About Phone' tab is 'Mobile State-Disconnected'. I have full signal strength and all that.
My thoughts are that it was, or rather is a phone specific issue and would appreciate someone else's thoughts on the matter. As to my problem I assume it will sort itself out in a little while.
FYI: Samsung Galaxy S2; Android 2.3.6; NOT rooted; Indian version; On Airtel Mobile Network.
Mobile network state disconnected.
Hi guys, I have the same problem with my network connection also my 3g does not work anymore, I`m play with some secret codes like a ##72786# on my epic 4g touch sprint phone flashed to metro pcs and now I have no 3G service. In the setting menu under network status say Sprint. How can I get my 3g back?. The mobile net. 3G is on and the wifi is off. I need to change the network to metro pcs in the status setting and how can do that? Thanks for your help and sorry for my bad English.
Hi there!
I've found several threads with this issue, but still not that serious like mine.
I've been using my GS II for 3 month without any problem, untill yesterday. During surfing on the net the network suddenly gone away and since I don't have mobile network connection. I've got IMEI, CSC, signal from provider (unlocked phone), my SIM card works in other devices, I also updated the firmware, I made several hard resets, checked other SIM cards, checked the problem with flight mode, but I haven't found any solutions. The signal sign is there in the upper corner, but I'm not able to connect to any providers for 48 hours.
Please help me. I don't know what to do
Maybe a country specific CSC change? I don't know how to do that. I have one .tar file for that but Odin can't install it. I'm a beginner here...
Thanks in advance...
Have you tried checking the access point settings?
Sent from my GT-I9100
Yes. They are fine. I've just changed them and put them to default again because there was no change.
When the phone went offline I was just surfing on the net so I did not change any options.
Any other ideas maybe?
Thanks...
try talking to your provider. Your account may have a problem which could be fixed by a simple reset on their end.
Thanks for the comment. Well, I've tried to use other sims for the same and also from other providers, even a sim from another country, and none of them worked. I also tried to put my sim into another phone and the sim works fine there. The only logical solution is that the problem is with the phone.
I guess it's worth a try, maybe they blocked the IMEI of the phone because of something? It's not a stolen mobile though.
Now I've got a flashed brand new mp4 player from samsung. Nice, it drives me crayz...
Another idea. While I was surfing on the net I installed "advanced task killer" (before the "crash" happened) and I killed some ordinary apps (not sure about this) then I just deleted the program. This connection rejecting thing happened after this. That's why I thought I should make a firmware update, maybe the problem was caused by this task killer. Well, don't know if the is a connection or not...
I have exactly the same proble with my Galaxy SII - I went on a long trip - when I got back it stopped working. Has anyone found a solution to this?
To reiterate - the phone sees all the networks, but when I select Vodafone UK I get the message "unable to select vodafone UK automatically". The sim card works fine in other phones - there is clearly an issue with the phone. The only thing that has changed is I have updated some of my apps on returning home.
Any ideas?

My CSC is XEU (correct for UK as far as I can see - and has worked for the past 3 months)
Sim card works fine in another phone
Network is fine (my wife is also on Vodafone and has no issues - my sim works on the network on her phone)
My Imei is correct
-Everyone else who has had this problem had no joy with a factory reset so I'm loathe to try it until I''ve tried everything else.
Any other ideas?
Just to recap:
The phone is stuck in emergency calls only mode
I can see all my local networks (Vodaphone, Orange etc...)
When I try to connect (in any of the modes 2g/3g) I get the error message
The sim card works fine in other phones
Other people's sim cards have the same issue in my phone
There are plenty of 'Emergency calls only' threads around, but the ones that have my exact symptoms never seem to get solved. Does anyone have any other ideas, or better, has anyone come across a thread where the issue was resolved? Getting pretty desperate.
tried rooting and flashing different modems maybe its a hardware problem with the modem.

i have the same problem in greece galaxy s2 i9100....in ics i havent network in 2.3.5 i have...i dont know why...in cm9 ics i have network...
Last update - I have flashed the phone to Ice Cream Sandwich, (LPQ version), which means I have:
Carried out a factory reset
Flashed a new ROM and Modem
When I rebooted it asked me for my carrier (Vodafone UK) and filled in the APN settings itself. I still have the same issue. I can't work out what is left that I haven't reset/reloaded that could still be causing issue. There can't be many settings left that aren't new?

i try to put manual apns but i cant save this in phone...in network search found my carrier but not conected...only with cm9 ics found network...pff...
Success?!?! It looks like we have tracked down the problem (extremely helpful input from another forum). Quick call to Vodafone and it turns out that my IMEI has been blacklisted (stolen!) Imagine my surprise - currently having a very interesting with Carphonewarehouse as to how hey managed to give me a stolen phone - should hopefully have everything resolved shortly

Very odd - when you first boot after a flash does it not ask you to select your contract type (that is the bit that automatically fills in the APN for me?)

Had the EXACT same issue on my Galaxy Note II for two days. My last hope was trying to restore my EFS with the EFS pro app.
Now when enabled my wifi at home and connected to my home network my sim prompted for the pin code.
Strange but I guess it was waiting for a connection (from my home wifi (not any other wifi) from a "half downloaded" app from the play store.
Anyways I'm happy this issue is resolved.
Does your phone prompt for a pincode when you start it? (mine said unable to complete download everytime it booted)
Hope this will help you guys...
Samsung Galaxy "Unable to connect. Try later" issue still remain
Hi guys,
I have the same issue with the following device:
Samsung Galaxy S3
I live in continental western Europe. Operators tried: BASE, MOBISTAR, PROXIMUS, POST.
The IMEI is correct, does not start with 00. The phone was bought from a shop, new, I have the invoice, so is legal, not stolen.
For some unknown reason, suddenly it does not want to connect to the mobile operators, any of them. I see "Emergency calls only". When I try to connect any one automatically or manually, I always get the message "Unable to connect. Try later".
The SIM card work well in another device, a Nokia C3-00. Another SIM does not work in my defective Samung S3. I sent back the device to the shop to be repaired and they gave it back to me saying it work very well, they just upgraded to the latest firmware, etc.
I am very annoyed because the device is unreliable. I have it in my pocket and do not realize it is not connected to the mobile network, I cannot be called or receive messages. Also I am unable to call.
The WIFI work well.
I tried everything, removing the SIM, inserting another, shutting down, enabling and disabling flight mode, nothing works.
But the later for some unkown reason and logic, it just work again for some time.
You guys wrote about some solution by looking in a folder, but I don't see that folder. Also you mention rooting. Does this mean cracking the phone? I do not wish to meddle with this, because I could destroy my device and I paid a lot for it. It will remove the warranty. So if you have a solution, please give a legal one.
Anyone have a hint or explanation for this strange behaviour?
Thanks a lot.
had a similar problem with galaxy core prime.
bought without a sim card and no knowledge of what network it was on.
every sim i tried was getting unable to connect error as i was trying to register on network
dont know if this will work for everyone as mine is a dual sim phone but here goes.
inserted two different sims from different providers, ee and vodafone.
reset phone to factory settings and when it booted back up, it recognised the ee sim card, went to mobile networks and network operators in settings and selected the ee network and presto, it registered ! used sim manager to select voda card and repeated selecting vodafone as carrier and it also registered straightaway
as i said none of the cards would register before on their own, but somehow this method worked for me.
hope this helps
had to set one sim to gsm only and other to autoconnect
Hi all, I landed in Heathrow for vacation a couple days ago and immediately bought a local sim (EE 500 mins, unl text, and 2gb data). I swapped it out while on the tube and I got and unknown sim icon in the status bar. Weirdly, it appears I can send and receive texts (I was getting messages from EE) but I cannot use data. Furthermore, when I took the Eurostar to Paris yesterday, I got a text from EE welcoming me to France, informing me of roaming charges etc so it is clearly communicating with their servers.
I'll be heading back to London on Tuesday, and I'd like to have data then.
I am rooted, but still running stock ROM.
Is this a Verizon, LG, EE problem? Or is it a combination?
Any help would be greatly appreciated
Thanks!
Probably some APN issue but I wouldn't know what exactly you need to do to fix it. Anytime you run a phone that's set up for one carrier on a different one you usually have to at the minimum change APN settings to have full functionality.
Maybe where you got the SIM from can give you the correct APN settings. Make sure and back up your existing APNs first.
Enjoy your vacation. Safe travels!
Sent from my VK810 4G
Thanks for the reply! I created the appropriate APN with info from their website but still no dice :/
Ur going to have issue the icon will remain as long as u are you using a non verizon sim as far as data normal issue have been not being able to recieve mms. Make sure data is enabled then recheck your apn make sure its fpr smartphones then if all else fails it possible your carrier may not be able to connect to data via verizon hardware
I am getting the same problem in the UK - see the OP - same 'unknown SIM' icon in the top bar. I have voice & text, but no data.
Two different carriers in the UK give me the same problem - 02 and EE - so it's not unique to one carrier. If anyone has further info I'd appreciate it - otherwise I'm down to put this phone aside & buy a new one as I'm living the the UK for a year or longer.
Has anyone been able to attach a Verizon LG G3 to a UK providers data? If so, how? LMK please!
Thx in advance!
Hello XDA,
I have a Galaxy Note 3. It is running:
Android 5.1.1 n9200zCU2AOl2 Phronesis V5;
kernel version 3.4.110-idleKernel-hlte-eur-6.6.5-note5port [email protected] #1
Unlocked
TLDR: I can't access APN or look at a list of networks. This is all I see: http://imgur.com/a/83YGW
I bought the phone from Rogers Canada. Unlocked last year. I recently attempted to port my number from Freedom Mobile to Public Mobile. I received an error when activating my SIM chip on their website, but when I powered up the phone. I was able to make calls, and to use data.
The data was unbearably slow, however, and so I went into mobile networks under settings, and told it to go to LTE. I don't remember what the exact setting set, and I can't reproduce it at the moment. I had LTE speeds on the phone now.
About three hours later, I noticed I had absolutely no ability to send or receive calls. But data was still working. I attempted to see if it was connecting to the wrong network, but when I went to see a list of mobile networks, nothing. Just those settings you see above on the screenshot.
Another hour had passed. Now, no data, no calls.
Public Mobile told me that there was an error in porting, and that they would fix it. They "confirmed" that it was fixed about four hours ago.
Despite being an unlocked phone, every SIM chip I put in fails to provide me with any connection. Now all it says on the lock screen is "searching for service."
I don't see what I could have done to have physically changed the menu settings inside the phone. I tried booting in safe mode. I even backed up my ROM, wiped it, and flashed an earlier backup from last year I saved. Nothing.
I'm really stuck, and would appreciate any advice that anyone can provide. I can also provide anything else you might need. Thanks.
