ive been using the phone for a few weeks now and it was fine until today, i cant connect to the internet via edge . ive tweaked with all the settings but nothing seems to work. everything else is fine . ie i can make calls and send text's but i cant connect to the internet. i checked under the status and it shows the mobile network state is disconnected. i have no clue as to wat this is since im new to android.
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.
I have a problem with roaming.
I am on MTS who has joined with Rogers network.
On stock ROM: 2-6-35-7-i9100xwkf3-cl276555 rootdell101 #2
I go to the US
Phone works on roaming
Can receive SMS
Cannot send SMS - Send fails
I have since rooted and installed Alienware 2-6-35-11 ninphetamine 2.1.3 xxkh3
I go to the US
Phone has 4/5 bars and can't get on network to roam
can't send/receive SMS
when dialing get the Mobile network unavailable message
My wife's samsung galaxy S i897 works fine -
Swapping SIMs with her yields the same failures on my S2 with her SIM.
In both cases, crossing the border home fixes the problem and life is grand.
I have tried:
1.enabling data roaming
2.rebooting
3.battery pull
4.swapping sims
Is anyone else having similar roaming issues - is there a ROM that actually works while roaming from Canada while in the US?
I have seen problems on my old Galaxy S and my wife's similar to this as when trying different ROMS, but have never gone across the border with any of these ROMS installed.
What I've seen with different ROMS is:
1. sometimes cannot get phone to get on network unless I setup the APN settings first
2. sometimes cannot get phone or data to work without enabling roaming mode. The phone actually says it's roaming even when it's on the home network
Is there anything I'm missing in the forums on this issue?
Thanks for the help
hmm, maybe you've tried, but have you checked if the APN list is accurate ?
i believe there is an app to set the APN on the market ( can't remember the name though, never had the need for it.)
or try to google if you can find the APN setting of your network provider.
Seem like an APN problem to me as you explain it.
on the phone, you can access that with :
Settings >> Mobile networks >> Access Point Names and then the details of each APN can be checked/edited.
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.

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...
Hello. I have an SM-G925F which I bought from Telekom Macedonia and I am still using my number from there also but I am currently in the US and would like to use it on T-Mobile USA.
I know that the device supports all the same bands as the SM-G925T model.
The problem I am having is that when my phone is set to LTE/WCDMA/GSM in the Network Mode settings, I do not have any data connection at all, only when I make a call, I start to get a data connection but only 3G/H+. If I switch my setting to WCDMA/GSM, then I get a data connection at all times like normal but it still is only 3G/H+. I have tried two different APNs and different settings in the APN but I still cannot get a data connection at all times on the LTE/WCDMA/GSM setting and I cannot get LTE/4G at all.
After contacting T-Mobile, all they came up with is to try to have the same software reinstalled on my phone. Does anyone have any experience with this and can anyone help me?
Anyone?
Call Tmobile and have them input your phone's IMEI in their system. Ask for the APN settings as well. I am on the same boat and one call to ATT got me from H to 4G. Your phone will just show 4G, not LTE but you will get LTE speeds regardless.
I tried doing that too. I called T-Mobile a few times and they confirmed my IMEI number being on the account but still no luck. It's really weird..sometimes I get 3G/H+ on the "LTE/WCDMA/GSM (auto connect)" network mode setting on the phone but most of the time, I get NO DATA connection at all..only the signal bars.
Any Update
Did you finally figure it out? Is LTE working now?
Hi All,
I am having issues in receiving and making a call when network type is set to LTE. I am missing a lot of calls and people find my number not reachable , even though i have full signal. I will have to try 2-3 times to make a call. I had this issue on MIUI and currently on MOKEE ROM or any other ROM as well
But when i set the network type to GSM/WCDMA auto, i can make and receive call without any issues.
Redmi note 3 - 3GB/64GB
Currently using SIM1 - airtel 4g and SD card in slot 2.
Current ROM: MOKEE-20160715024 Build
Baseband: -8976_GEN_PACK-3.53308.1.57464.1
Let me know if you any one has experienced this issue and have a solution.
I have same problem with mine. When connected to LTE or even 3G, I have no call in or out. Only posible calls with 2G network (but no data of course).
The strange thing for me is that with another network it Works well. I am not sure if it is a faulty device or is some problem with radio. Someone has seen and solved this issue?
no calls while on lte
Facing same issue, no solution yet
