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...
yesterday i brought AT&T's Samsung galaxy s2 SGH-i777(locked) and i unlocked that mobile through cellunlocker.com to pay 11$ for unlock code..they sent 8digit code..its works perfectly...after that i put my IDEA cellular INDIA SIM card on it..its showing some signal..but i am not able to make a calls..its saying network not registered.....after i restart the mobile it took "T-Mobile" network for a moment and lost..after that nomore connection.
when i go to wireless and network/ mobile networks/ network operators only thing which comes written is "DEFAULT SETUP" and that is greyed out. (when i tap on nothing happens).
also when i change back to my old AT&T sim, i am not able to access that greyed out area.
can someone please guide me through it..??
i am new to android phone..currently ia m roaming with T-mobile network in USA-Oklahoma.
my nokia e-5 working perfectly when i switch back SIM on it.
Please help me to how i got signal on my galaxy s2.
trouble shooting done
mobile not in flight mode...wifi working fine...2nd time i removed battery for a while and restart.it tooks network for 2minutes ..i make a blank call to other mobile...after that no signal...
below is my mobile information:
Model no - samsung-sgh-i777
android version 2.3.6
baseband verson- i777uckk6
kernel verson - 2.6.35.7
build number - gingerbread.uckk6
STATUS-
Signal strength- -101dBm 6asu
mobile network type- GPRS
service state- out of service
roaming- not roaming
mobile network state- disconnected
IMEI- 35805504356xxxx
IMEI SV- 03
First thing's first: never post your IMEI. You should take that down ASAP.
Secondly: I have no idea what's wrong with your phone, but our phone is free to unlock. As in, you didn't have to pay anything, all you had to do was root and use an app from the Play Store.
Thirdly: I believe you cannot select the network operator while on a stock ROM (either 2.3.4 or 2.3.6), no matter what you tried. You'd need to flash a custom ROM to do that (not entirely sure, someone correct me if I'm wrong).
Fourthly: Note that the I777 doesn't have the hardware to use T-Mobile's 3G/4G services. You'll only be able to run on Edge, period. There are no workarounds.
Lastly: To fix your problem, I would recommend starting over. That is, wiping all data/caches and flashing back to complete stock 2.3.4. Then root it, and use the app I mentioned before to unlock. Flash a custom ROM after that if you still want the ability to select the network operator.
Read all of the links in the sticky if you want to follow any of the suggestions I made. And I mean, read all of them before you do anything to your phone. You need to fully understand everything you are about to do before you do it.
P.S. Please hit my thanks button if I helped you. Good luck!

Read only posts and threads here. Other websites have outdated info. No ROM is best, try them all yourself. You need to better understand what a ROM is, so search for that. Keep reading, I told you it will take you several days. I won't spoon feed you forever.

good observation..you rocz:good:
I know this has been a widespread issue and has been asked many times, but I don't see any serious effort on how to fix it. I've seen also someone in other forum said that the kind of SIM card and network is also could causing the issue.
Regarding to my problem is, at first I couldn't connect to mobile data using CM10, then suddenly it works, so I figure that there's something with the network system. Few days after I have to travel to another city and the problem rise again. So again I figure that the network system that caused the problem and the way CM10 communicate with the network, only this time I wouldn't just live with it.
I'm thinking trying to fix it myself, the problem is I don't know what files that part of CM10 system that deals with mobile data? Could you point me what parts of system files I need to look?
This will not be an easy task for me to solved it, so I would very gratefull if you can understand my low-end knowledge and effort.

The APNs go away on flashing cm10.(i was through the same situation. And I'm on cm10 oly). Before I flashed, I knew the APNs would go away, so I manually wrote it down and added back again. U should probably try selecting ur service provider manually from the network settings and see if the APN comes.
And which network are u on BTW?

Let me try clear the situation, I did get mobile data using CM10 before in city A, then I did a bussines travel to another city in my country, when I arrived I turn on the phone then I loose mobile data. So the APN is excatly the same APN that I used before because the ROM is still the same ROM, I did not flashed new ROM. Untill now I'm still using the same settings on the same ROM.
I'm in Indonesia using INDOSAT provider. And the APN is correct. I did try selecting networks manually, but it keeps failing it said "error while searching for networks". Nationally roaming is not an issue because almost all provider here are free national roaming.

Oh! Did you report to the service provider about this issue? May be its from them!
Just got an HTC One made for T-Mobile and when I insert my mirco sim I get a WiFi Calling Error: ER05 and get zero service. The phone recognizes the phone number on my sim. Is there a solution to this problem? I'm on 4.1.2. The IMEI also checks out on T-Mobile's website.
Maybe I should just re-word the entire thing by saying I get limited service but zero bars, but it says emergency calls only. The previous owner had T-Mobile and it worked for them.
I'm just looking for a way for my T-Mobile HTC One to recognize that I have T-Mobile.

I've done this and the error goes away but still no service, it does however say emergency calls only.
I am using Virgin Media here in the UK for my Galaxy S III (GT-I9300) mobile services. I have rooted* the phone and use Cyanogenmod 11 (currently use the nightly build 20140623). I have been using this ROM since probably the 5th/June which is when I obtained the phone.
My problem is that the network association identifies as T-Mobile. I have no idea why. And even though I use the Virgin Mobile APN settings (which I had to manually add using information available on Virgin Media's website) the network string may sometimes show up as Orange when I am using 3G data services. I do not allow data roaming on the phone and I am able to use my phone as you would expect, i.e. able to make calls, receive them and don't have any issues (or at least have not experienced any so far).
Can you help identify how I may "fix" this?
FYI: I have tried searching both the forum and using Google with the "XDA" suffix to locate similar posts. The one I have found is not the same problem so not useful to me (http://forum.xda-developers.com/galaxy-s3/help/how-to-change-default-mobile-network-t2315737).
*Apologies if my terminology is incorrect. "Rooted", "flashing" and "using a custom ROM" are all the same to me. I can however confirm that I am using said CM11 nightly build, CWM Recovery v6.0.4.6, and didn't exactly find the whole "rooting" thing a straightforward experience.
44 views and nobody has any feedback. Am I doing something wrong here?...
Thanks.
I dont know much about Virgin´s mobile service but Orange and T-Mobile are the same company now (EE) so perhaps Virgin have a partnership deal with EE and you are able to use thier network. Either way, you are not roaming when you are in the UK.
Your rom is missing the correct network settings and tables, ask the rom chef or try another rom.
@boomboomer care to elaborate?
Flash a stock firmware and your problems will disappear. Ask your rom chef to add the right network settings or try another rom that has them.
In what file are these network setting written?
