[Q] "Unable To Register on network" - Galaxy S III Q&A, Help & Troubleshooting

Hello I have a really annoying but strange issue I cant make phone calls or send and receive text messages but I can browse the internet.
I have a Samsung Galaxy S3 which im sure is sim unlocked but im not 100% sure. It has been working ok up until recently something has changed but Ill be dammed if I know.
I am using GiffGaff and reported my SIM lost so they send me a new one with the same number on it but this did not work.
Im running the stock ROM ..I tried to re-root the phone but this did not work.
I have done a factory reset this has not worked.
If I take the sim out of the S3 and put in into either my old HTC Desire or HTC Desire S it works fine i.e I can make and recieve phone calls.
But soon as I put it back in the S3 it says "Unable to regsiter on network" so it HAS to be the S3 but im sure it is sim unlocked! ive previosuly tried Vodoo unlocker and it said sim lock status inactive could it be wrong?
I tried similar to this: (But when I got to network lock it says on my S3 (MENU NOT EXIST PRESS BACK KEY Current command is 186) what does this mean???
==============================================================================
"Put in a different SIM card to the one you use with your carrier.
Switch the device off and on again with the SIM card in place.
Open your dial pad and then type in *#197328640#.

Then hit Menus and choose Back. You should now see Network Lock. Then choose [4] NW Lock NV Data INITIALLIZ."

Please can someone help !!

Does your IMEI start with 00 now?

No it starts 35 ?

so it matches with the one under the battery?

If the SIM works in other phones then the S3 is the problem, try a SIM from another network in the S3 to see if that connects.
If it doesn't then I'd guess the phone IMEI has either been blocked or is locked to another network (but wou would see a network lock message in that case). You say you can still access data - are you sure that is with wifi turned off? If it is unable to register on the network then gprs won't work either.
I suppose it might be possible for a part of the radio modem to corrupt, or a hardware fault. Try flashing a full stock ROM including a radio, with a full wipe before trying the SIM again.

For the post above this the SIM on the phone and battery are the same apart from at the end of the number there is a " / follow by a number" this is differant.
On my mobile the IMEI ends in 6785701 /04
on the battery the IMEI ends in 678570 /1
Not sure if thats relevant?
I am not conncencted by Wifi soon as i hit "Mobile Data" GPRS is enabled and data is enabled. Ok ill try what you said.

The bit after / is not relevant on the IMEI .
Have you actually entered the GiffGaff APN settings .
Or are you running on O2/ Tesco settings and not Giffgaffs .
Backup data and factory reset first .
Then update firmware .

I have double checked thatmy APN settings are correct as used this gudie: http://community.giffgaff.com/t5/Le...tings-for-Samsung-Galaxy-S3-Also/td-p/4491856
I know they must be working as soon as I enable the giff gaff APN I get GPRS data just i still cant make phone calls.
I have already tried a factory reset this didnt make any differance. When I try to force and upgrade on the S3 it says "Your device has been modified sotware updates are not avialble"
I have ordered a free micro sim from Three (thats the network i know my S3 was originaly supplied by) once i have triem them ill update.

I have run a CHECK MEND Report it is showing as this:
Ever blocked CheckMEND has a record of this item having been blocked by a cell phone network
Currently blocked CheckMEND has a record that this item is currently blocked by one or more cell phone networks
Lost CheckMEND has no record that this item is currently reported as lost
Stolen CheckMEND has no record that this item is currently reported as stolen
Insurance claim CheckMEND has no record that this item has been subject to an insurance claim
Possible counterfeit CheckMEND has no records that this identifier has been used in counterfeit products
Previous use CheckMEND has no records indicating this is a used item.
Possible clone CheckMEND has no records that this identifier has been used in cloned products
Recycled CheckMEND has no records that this item has been recycled or refurbished
Contract status CheckMEND has no records relating to this items network contract status
Warranty CheckMEND has no records that this item has been subject to a warranty claim
Finance CheckMEND has no records that this item is subject to a current finance agreement
So looks like its blocked ill try another sim on it.. hmm

Its the IMEI that gets blocked not the sim .But worth trying another sim anyway .

[Q] "Unable to connect. Try later"

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?)
my solution
http://forum.xda-developers.com/showpost.php?p=25509654&postcount=279
this helped to 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

[Q] Can't Make/Recieved Calls or SMS

Hi Guys,
My friend has asked me for some help with his x10i.
He's purchased it from a market, and it was locked to T-mobile.
Its since been network unlocked by a local store, in theory to allow use of any network sim card.
However when you boot the phone with a sim card in, it comes up on the notification bar
"Phone Not Allowed MM#6"
It will show the little signal bar full.
Checking phone status it shows
Service state - In service
Mobile Network State Disconnected.
It appears to register onto a network, be that orange o2 ect.
But we are unable to make outbound calls, receive calls.
Yet browsing via gprs is working.
I have checked the IMEI with the T mobile. They advised that the phone is clean and not barred.
I have Tried different Sim cards i know are working.
I have Flashed the Firmware back to Stock, Tried the Latest Firm and a few other different combinations.
I am now Stuck.
Any suggestions?
Thank you

did u try calling the network provider your sim card is with? they usually may have to program the network with imei number of the phone
u can also try going to network settings, search networks and choose the one u r on.

Sim card not registered?

Hi guy's, have a UK SGS2. It's rooted and running Criskelo ICS rom. I've recently been in Brazil for 6 months, my phone worked fine over there. I've come back to the UK and got a standard Vodafone PAYG sim card. When I try and use it the phone says "not registered on network"
The sim card itself is fine as it works in my old mans SGS2.
I have wiped the phone and installed the standard software and it's still the same.
Anyone got any ideas what could be up?
The phone could be network locked (sim lock)
Sent from my GT-I9300 using xda premium
That's what the guy on Vodafone web chat suggested.
How and why would it get network blocked?
The phone was originally on the 3 network. I bought it 2nd hand about 1.5 years ago and it's been fine on T-mobile ever since.
If it is sim locked, is there a way to unlock it?
You can unlock with:
https://play.google.com/store/apps/...sImV1LmNoYWluZmlyZS5zZ3Myc2ltdW5sb2NrY29kZSJd
It's free on google play.
I don't think it's sim locked, I can put any chip in it. It doesn't ask me for an unlock code.
I have run the sim unlock tool. The code it came up with is 00000000
When you go into the network settings, it shows all the service providers. every provider I click on says "can't register on the network"
I'm wondering if i've had some sort of network update in Brazil that's screwed it up?

I'm sure its something to do with being abroad as i've read about someone that had the same issue when they went from China to Denmark.
If I go to settings - phone it says...
Network - Unknown
Signal Strength - 103 dBm 5 asu
Mobile Network Type - HSDPA:9
Service State - Out of Service
Roaming - Not Roaming
Mobile Network State - Disconnected
My Phone Number - Unknown
IMEI - the correct number, I checked
The fault isn't with the sim card itself, I can use it in other phones and I can save a contact to it in this phone.
I'm wondering if some of those network settings I had from the Brazilian phone company's have messed something up.

corrupted efs is most of the time the main cause for such issues, but yours seems to be ok.
but then I don't know what causes it, sorry .
if I were you I would not make experiments so if you did not flash anything, you are are unrooted and you still have warranty I would take it to a samsung service center.

Try not to use the "auto select" feature in the Mobile Network settings, try to explicitly choose a network instead. Choose your mobile carrier's network preferently, and if it doesn't connect (it may take a long time to connect), try other networks.
If it still doesn't work, well maybe speak with a tech at one of your carrier's shop, maybe they can help you.

No Network Operator List and No Connection

Phone specs out of the way first: GT-i9300, Android 4.3 (via OTA), sim unlocked, not rooted, Baseband i9300UBUGNF1, Kernel 3.0.31-2320216, and the IMEI matches the frame.
So I've got a problem that's very similar to a lot of other people with one or two exceptions. I get the "Mobile Network Not Available" error message and I've tried the suggested fixes except for the Ariza patch and I haven't tried changing my modem. I don't want to jump into either of them yet because I'm not sure my problem is the same as all the others. Here's why:
When I go to set the network manually via Settings > More Networks > Mobile Networks > Network Operators > Wait till your device is searching for operators. Once the search is done it will show a list of Network Operators ... Nope, not mine. Mine shows nothing and goes right back to the menu showing Search Networks and Select Automatically. Tapping Search Networks brings the same result. If I set the Network Mode on the previous menu to GSM only, it takes less time to search, but still returns nothing.
Also, I don't have any bars. Not as in having bad signal, but as in there is no signal strength indicator in the status bar. Instead, I have a circle with a line through it next to the battery level indicator. I can not even make emergency calls with the phone.
I haven't found anyone with this particular problem yet, even though I've been searching all day. Perhaps I'm not searching for the right thing?
I've tried an old ATT sim and an active GivMobile sim, both with the same results. Both sims will register networks on other phones. I started out on 4.1.2 and did the OTA updates to get to 4.3 with no change in symptoms. I did a factory reset before doing the updates. I've never had a custom ROM on the phone. The IMEI doesn't show up as blacklisted on any site I used to check it. I even went as far as replacing the SIM card reader.
Could my antenna be bad? Could I have the wrong modem for the networks I'm trying to get onto? Any opinions or direction would be greatly appreciated.

"(via OTA)" means you have samsung's original ROM?
Reflashing a Samsung-based ROM fixed my IMEI problem some months ago. I don't know if you are on a custom or original ROM, if it is a custom ROM I believe that you already know the process...
Revolution HD 53 is a great custom samsung-based ROM and fixed my issues. Be careful on what you flash, if you're going to do this
Im having the same problem as you had. Just wondering if you found out how to fix your phone. Ive a samsung j3(2016) SM-J320FN. Got a new sim the other day and have been trying everything to get service, restored to factory setting but nothing seems to be working. Like you nothing came up in network operators. Sim works fine in other phones. If anyone can shead some light on the suituation please feel free to reply
