Is my Sim card at fault? - Galaxy S III Q&A, Help & Troubleshooting

Hi all.
Does anyone know if it is normal to have your Sim card provider listed twice in the Network operators list. As my Galaxy S3 shows '3' twice and O2,EE and Vodafone just the once.
Reason I ask is that I have been having problems with a new S6 not working with my new Sim card though '3' said it was fine.(I had just recently been in to have my sim changed from Micro to Nano size) So I'm currently in the process of sending it back. When I put the Sim back in my S3 it was doing the exact same thing the S6 was. Showing it was connected to the '3' network but dropping the signal all the time and going into 'Emergency calls only' mode. Manually switched to the other '3' in Network operators list and phone now works fine.
I could never recall it ever showing '3' twice so wondered if ther store had programmed the sim wrong.
Anyone?
Cheers
Mark

[Help]Phone Not Allowed MM#6

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

barred but sim working

so back again
recently had a post about my galaxy s2 ( http://forum.xda-developers.com/showthread.php?t=1502801 ) having network connection problems
so since the galaxy was bought second hand, i unblocked it with helroz application. The point is - it doesn't recognize my sim card in the country where i am now (Orange - France -only emergency calls), but accpets my foreign sim card (Roaming of course - but connected to one of the operators (SFR)).
Does this suppose to mean it's barred?
Does not accept a sim card
Sim Card faulty
Sim Card blocked .
And what do you mean by not accept have you set the Orange network connections ??
jje
both 2 cards work perfectly on other phones, so i don't think it's sim card problem
for each card the gsm ask for pin code - correctly input
but only for the orange card shows - emergency calls only
by settings you mean the APN?
aren't they supposed to be automatic when you insert the sim?

Click to expand...
Click to collapse
Nope, sometime you need to configure yourself, send message by you network operator or manual install, just give them a call
APN are fine
they were correct, deleted anyway and input again, same situation....
other suggestions?
still don't get if phone is barred why is my foreign sim card working since it uses the roaming netowrk?

Sim card not registered?

Hi guy's, have a UK SGS2. It's rooted and running Criskelo ICS rom. I've recently been in Brazil for 6 months, my phone worked fine over there. I've come back to the UK and got a standard Vodafone PAYG sim card. When I try and use it the phone says "not registered on network"
The sim card itself is fine as it works in my old mans SGS2.
I have wiped the phone and installed the standard software and it's still the same.
Anyone got any ideas what could be up?
The phone could be network locked (sim lock)
Sent from my GT-I9300 using xda premium
That's what the guy on Vodafone web chat suggested.
How and why would it get network blocked?
The phone was originally on the 3 network. I bought it 2nd hand about 1.5 years ago and it's been fine on T-mobile ever since.
If it is sim locked, is there a way to unlock it?
You can unlock with:
https://play.google.com/store/apps/...sImV1LmNoYWluZmlyZS5zZ3Myc2ltdW5sb2NrY29kZSJd
It's free on google play.
I don't think it's sim locked, I can put any chip in it. It doesn't ask me for an unlock code.
I have run the sim unlock tool. The code it came up with is 00000000
When you go into the network settings, it shows all the service providers. every provider I click on says "can't register on the network"
I'm wondering if i've had some sort of network update in Brazil that's screwed it up?

I'm sure its something to do with being abroad as i've read about someone that had the same issue when they went from China to Denmark.
If I go to settings - phone it says...
Network - Unknown
Signal Strength - 103 dBm 5 asu
Mobile Network Type - HSDPA:9
Service State - Out of Service
Roaming - Not Roaming
Mobile Network State - Disconnected
My Phone Number - Unknown
IMEI - the correct number, I checked
The fault isn't with the sim card itself, I can use it in other phones and I can save a contact to it in this phone.
I'm wondering if some of those network settings I had from the Brazilian phone company's have messed something up.

Cannot connect to network

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 !!

SAMSUNG PIE: SIM card detected and enabled but cannnot find/connect to mobie network

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.
