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...
I just picked up this phone last weekend. It's unlocked, and it's working great with T-Mobile's towers, but the notification bar in the lock screen says "No SIM card - T-Mobile". The message is gone as soon as I unlock the screen. Only other problem is that the T-Mobile My Account app won't update my minutes/texts/data, but I don't care much about that.
Any advice on eliminating that message?

Since that's a custom rom, you might be able to go into the setting and change the Service tag? Try going into settings and try that also do you have the T-Mobile LTE APN?
Hi, I have a problem with service, I don't have any, just empty triangle in the right corner.
I've tried three sim cards (Slovakian's O2, UK's three, O2 and Vodafone) and still when I'm trying to call it shows message "no network available"
Its not because of airplane mode.
What should I do? Thanks.
Did you resolve this? I have the same problem

Check if your IMEI numbers are displayed in Settings.

Take a look at APN settings (you might have to set them manually), if your EMEI numbers are there and APN settings are correct, then it's a hardware issue.
I just got a P9000 today and after a quick setup of the device via wifi I proceeded to inset my sim card from the uk network 3/three.
Now my network shows up when doing a search, and in the SIM settings it shows 3 UK for all options, but only the calls option is greyed out, and I am unable to make any calls with the phone whatsoever.
I don't get the no network message error (except when I am in an area with no coverage i.e. in my house) .
I've tried the sim card in both slot 1 and 2 to no avail.
I get 3 showing up in the notification tray icon which toggles data, plus it shows 3/4g next to the signal strength bar when I'm somewhere that gets a mobile signal.
It even show the correct network in the SIM status within the about phone section of android settings with the correct IMEI number.
Does anyone have any idea on my issues and any potential fixes/test/things I can try in order to get calls working?
Seems like my problem solved itself and I can now make calls.
Don't know what was/is wrong but calls option is still greyed out, though I made 2 test calls this morning (to Landline and mobile) which worked, then later on I made a call of a few minutes which worked as well.
Hi everyone, I recently bought an used S8+ (G955F). The seller didn't say it had any problems. I happily went home, inserted my sim card and turned on the phone. Entered the pin code. Then it all went downhill really fast. I will list my observations here (tried with multiple sim cards from different carriers, same stuff every time):
Signal - 1/4 bars when out of the city, 4/4 when in the city.
When sim is inserted and the phone is turned on pin code is required.
When trying to call anyone, Not registered on network error is shown.
When trying to send an sms to anyone, "Currently unable to send your message . It will be sent when the service becomes available" error is shown.
When pressing Select network operator automatically in network settings, "Unable to connect. Try later" error is shown.
When pressing Select manually, "Error while searching for networks" error is shown.
Internet not working as well.
At first I thought it was a demo phone, checked IMEI and baseband version - they were there, so I think it isn't a demo phone.
Could you guys help me out in troubleshooting this device? Could that be a software or hardware problem? Any help will be appreciated <3
Some things I forgot to mention
MM#6 error is present.
However, I checked imei.info and imei24, the phone is not blacklisted on both. Also it shows as unlocked. What is going on

I'm starting to wonder if this community is dead, lmao. Or just unwilling to help. Sad face.
