Hello everybody! I have the problem with my Samsung Vibrant, please help me.
The phone doesn't get any service when you insert you T-Mobile sim card. It says "not registered in network" whenever you make a call with it.
It get signals as shown on the signal bars but says "not registered in network".
I don't know is this a software or devise problem. may be if I'll unlock phone it will be work.

It could be that you have a bad sim card. You can call tmobile and they will send you a new one. Or you can go by the store and they will also.
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?)

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
Hi,
I purchased a Chinese Android mobile which has the MTK6573 chipset. It is called a Star A3.
Love the phone however I regularly see the alert/error "Restricted access changed" in the status bar and the signal drops off both SIMS. If I pull down the status bar and check details it says "Voice call service blocked".
What is interesting is that it is always the Vodafone NZ SIM card even if I swap cards between SIM slots. Other SIM is 2Degrees.
I've searched the internet but there seems very little info on this subject other than to say that some HD9 users have had the same issue and have Spice Mi 350n users.
Some suggest it could be a IMEI issue but I'm not so sure.
Does anyone have any ideas?
Can provide more info on request.
Thanks in advance.
*** Additional info... I've turned off my SIM data connection which was linked to my 2Degrees SIM and now both SIMS manifest the same error. If I re-enable data on the 2Degrees SIM only the Vodafone SIM gives the error ***
I have the same issue on an IHTC HD2 bought on fastcards with the same chinese android. I don t know what the problem is. Everytime I turn the phone on there is available network, but after 5sec it gets blocked for good. I only have one SIM card and data connection doesn't work. This is freaking annoying ...
Thanks for the attention
Sounds like a slightly different issue than the one I have as my phone will reconnect and I can use it but it frequently drops off.
Perhaps turn your phone on without the SIM card in it and get your IMEI numbers.
You can google websites to check your IMEI numbers are valid. Perhaps they are not valid and your carrier blocks the phone?
Please use the Q&A Forum for questions Thanks
Moving to Q&A
Have found one other thing...
If you go into mobile network settings and change the network mode from say Auto to WCDMA only or GSM only you receive the "Restricted access changed" error notification immediately so I'm guessing it is related somehow?
It would appear the "Restricted access changed" notification appears whenever the network mode is changed from 2G to 3G either automatically or manually.
Images attached.
Occam's Razor strikes again
I had this same problem with an unlocked phone on AT&T network. Seemed to happen totally at random. It was driving me nuts, and nobody from AT&T could figure it out.
It occurred to me that the problem might be physical when the phone failed to recognize the SIM at all one time. Seems to be that the SIM card wasn't making good contact with the socket. I put a few pieces of scotch tape on the SIM card so that it fit a lot tighter and made really good contact, and I haven't had a single problem since.
(I don't know enough about it to explain why this worked for me, but I theorize that a loose or weak connection somehow fails out and introduces some kind of garbage data that the phone and/or network doesn't like, and it gets blocked as a result.)
Thanks for the post.
The problem is that between me and my friends there are about 5 of the exact same model all doing the exact same thing.
And ALWAYS when you go into network settings and change from say AUTO (WDSA/GSM) TO GSM ONLY.
Cheers
I'm curious to know if taping the SIM card so it makes better contact solves the problem for you. Does this problem happen with different SIM cards of different brands and networks or do you and all your friends have the same?
Hi again, tapping the SIM card does not appear to make any difference. I've also tried thickening the SIM card by sticking a layer of tape to it.
Seems to happen in low reception areas where the phone may lose signal and then reconnect to the network... I guess similar to how it is replicated by changing network mode.
Can you repliacate it on your phone by change the network mode? e.g. auto wcdma/gsm to gsm only
Hi i had the same version Star A3 iam frome Egypt and had the same problem i tried to put different sims from different agents but the same problem any person can tell me how to connect my android mobile with pc or from where can i get its driver
Thank you

I just changed my htc desire to a one S. Same Sim. It keeps popping up 'preparing sim' and 'restricted access changed'. Never did this in the desire. Only the handset has changed. It's not a poorly fitting sim. You can shake, bash, etc. no effect. It'll happen quite often. Could certainly be as others state when switching from 3g to gsm etc.
It seems I spoke too soon. My phone (Blu Studio 5.3) started doing it again. I can produce the "restricted access changed" message by switching from WCDMA/GSM Auto to GSM or WCDMA only and from WCDMA to GSM or vice versa. It's something with the switchover.
I have noticed that I get Restriction Access Changed message only when 3G is turned on. I turn 3G off and the phone does not lose the network any more. Yet to figure out why it happens...
This started happening to me today and like the post above mine only after switching 3G off does the restriction go away. This is annoying but I'm about to reinstall my rom and see if that helps.
Just had the same problem on my SGS3. Only thing that fixed it was a powerdown and a battery pull. Hope it doesn't happen again.
Same problem
I have tried putting in 2 different sims. i bought a fake iphone 5 from china. it is saying no service: restricted access changed. Please help!!!
I'm getting this today with a Nexus 4 running on O2 UK. I've never seen it before on any phone and have been on O2 for years.
I sometimes can't dial out and calls in are going to answer phone. Also, texts are not getting through.
Airplane mode off/on seems to work.
The weather is appalling here today (Snow) I wonder if it is to blame.
I have contacted O2 and spoke to a guy (who knew a lot less that I did about the device/network). Anyway, a new SIM is being sent out. We'll see.
---------- Post added at 03:16 PM ---------- Previous post was at 03:06 PM ----------
Update. My wife's phone also not working (O2) although she is not getting the "Restricted access changed..." error in her notification tray.
I can confirm this is happened on my Nexus 4 also. cell reception disappears for a moment then comes back. after that all seems to be working as normal and hasn't caused any problems with me, except for the mystery and intrigue. does anyone know what causes it? I receive the notification "restricted access changed" and then when i pull down the notification bar to look at the notification, the notification is GONE ! it does not stay in there.
I'm definitely putting my Nexus 4 issue with this down to the heavy snow that day. It hasn't happened since.
New Nexus 4 here with t-mobile prepaid. Had it happen last night when I got home for the first time. It was showing 2 notifications, one for voice and one for data. When you click them, they go away. Saw them appear a couple more time through the night and this morning they were also showing.
No snow here though...
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
Hi,
I purchased a USED Galaxy A7 2018 dual sim F variant. When I first inserted my SIM card, it was working fine. 4G and calls, all were working.
But after I factory resat it, mobile network stopped working or even detecting. SIM card is still detected and I can see it in "connections" under SIM cards in settings app on my phone. But when I try to dial a number it says "not registered on network". On lock screen, it says emergency calls only. When I go to "mobile networks" in settings app and tap to select network automatically or manually, it gives error that unable to find/connect to a network.
I tried three different sim cards yet same thing happens. SIM cards work just fine in other phones. Also, it is not a problem with sim tray on phone as sim card is detected and shown and as I said before, mobile network was working fine before resetting the phone.
When I purchased it, there was a custom ROM installed on it and OEM Unlocking was ON. I installed latest stock ROM from Samsung plus a couple of stock ROMS but same thing happens with every ROM.
I am out of ideas on what should I do now. I would really appreciate any help anyone can give.
Thanks.
Finally found a solution.
