Hello,
I have a Poco F1 where I can't get Roaming to work. First I had called my Provider for a Roaming permisson, after the Phone still showed up "no Network - only Emergency Calls" I tried the Sim-Card in another phone it worked as expected (Phone and Network connections).
Then I put back the Sim into the Poco F1 it still showes up "no Network"...tried different options in settings, a manual network search and so on....
still no luck.
And now the part that drives me mad....if I use another Sim Card in the Poco, Roaming works as expected, too
So Sim-Card works, Phone works, it looks like only this Sim in combination with the Poco doesn't work!?
Did anyone else did a similar behavior or any idea where the issue could be?
Thanks in advance!

May be ask your provider to change your sim?

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...

Remove both sims, turn it off, place jio sim and turn it on. Make sure LTE mode is on for the sim.
Go to mobile networks, and choose accesspoints, select loop or jionet if seen.
If list is empty, click menu, create, name it jionet in first to items, click save. and select it. see if it helps.
Mine was having trouble, so i flashed Krexus rom, it's connecting now.

Which model of Honor 5X are you using ?
Indian Model (KIW-L22) Supports Jio sim. Other country models might support Jio sim if it is configured for Band 3 (1800Mhz), Band 5 (850Mhz), Band 40 (2300Mhz).
Mine is L24, it supports Bands 3 n 5.. i got JIO signal too but No LTE data even after creating APNs with EMUI. Only after changing to CM/Krexus, data started working. Tried APN jionet and www none worked even after restarts.

You should contact JIO customer support if the issue persists.
I have KIW-L23 which supports only Band 3. Still I get LTE data after setting up the APN as jionet
dont worry, this happened to me too, just do this,,
remove sim card,
make sure you insert jio in sim 1
reboot
and this is important "SELECT DEFAULT SIM CARD FOR DATA" in settings
reboot,
you should be all set now,
For me, somehow Jionet apn did not work.. apn www worked fine.
Have few queries.
In Settings -> Dual SIM settings
Have you set the 4G/3G slot to the JIO SIM slot?
Have you set JIO SIM slot as default for mobile data?

are you on lineageOS ROM?
I couldn't see any posts about this for over 20 pages, I apologize if this is a known solution.
I just fixed, and bypassed FRP on an Honor 5X at work and I started using it all day with my AT&T SIM card. When I got home, it says "network unavailable" where the carrier name should be on the top left and it leaves me with absolutely no connection to the network. It does, oddly enough, register the phone number so the SIM card is being read. I tried the APN settings and nothing.
I have not rooted it yet, there's no TWRP files, just a stock phone. And yes, the SIM card does work in the Galaxy S5 Active it's in right now. Any idea how to fix this?
It isnt working in those two phones if am not wrong !!
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.
