No SIM card | Emergency calls only - Galaxy S6 Q&A, Help & Troubleshooting

Hi everyone,
I have bought a new Galaxy s6 from France (SFR but Sim-free), I tooked it home to Israel and put my sim card and all worked fine but in the version He havent Hebrew in language so I flashed the stock ROM official of Israel from sammobile.com and all worked excellent.
I was one day with the phone and bad surprise... after some hours, without I do something the phone give me a message "No SIM card | Emergency calls only". if I try to call it give me a message "No registred at network". I try to put another sim, i try to flash it back to stock rom of sfr, i try all wiping option and nothing.
What is the most strange is if pull out the sim tray (with a sim card) it give me a message "SIM card removed. Unable to detect you SIM card. Your device will restart tocheck for your SIM card".and if I pull it in it message me "SIM card added. Restart device to access mobile networks." so I believe the sim tray is ok...
Anyone can help me please?

This looks like you have not activated the region lock. When you buy any S6 or S6 edge it comes region locked. To unlock it you have to make a 5 min phone call using a sim from the region you bought it in. Once the call is made the region lock is removed. It does state this on a sticker on the side of the box of the phone.

But the phone worked perfrect at the start... it's normal?

I cant answer that issue sorry but all samsung phones now carry a region lock and have to be used in their region of purchase first.

i tried anything but the phone dont give any option to put code of unlock anywhere

Hey may be i can help...
Try this...
Step 1. At first you will need to get a foreign SIM card.
Step 2. Now turn off your device and Insert the SIM card.
Step 3. Turn on your device.
Step 4. Tap on the Dial pad and type here the code “ *#197328640#”.
Step 5. Now select these options step by step- “ [1] UMTS >> [1] Debug Screen >>
[8] Phone Control >> [6] Network Lock >> Options [3] Perso SHA256 OFF ”.
Step 6. Go back to your device home screen.
Step 7. Here you should see a “Network Lock” message, now you choose “[4] NW Lock
NV Data INITIALIZE“.

You can also bring your unit to local Israeli Samsung store for warranty repair.

The region lock does not require a code to be entered nor can a code be entered. Its automatic. When new you need to make a 5 min phone call with a sim card from the region you bought the phone then it unlocks automatically. For example I bought mine in the UK but am using it while working in saudi. Before leaving the UK I made a 5 minute call with my uk EE sim card. Phone now happily accepts my saudi sim card.

The same problem happened to me, I am Iran
I could not yet solved

One solution to this problem does not have a friend?

is happen to me too, i make the 5 minutes call in the UE. When i came back to argentina the phone read my countrry sim card at first. work well for a month and then happen the same thing. Any possible solution to this problem??

hi so i have same problem i try to change cert file but stay same problem

Same problem with my G920F! Used in the UK fine and then brought to the US with me where it worked fine for 2 weeks and suddenly doing this!

I have the same issue as above. The only difference is I still use the phone in Uk (O2 unlocked phone with Ee sim). After flashing another rom then returning to stock (but unbranded stock firmware, not the original O2 one) i lost capacity of giving / receiving calls / texts, some weeks later. Since then i tried flashing several stock roms (O2, Ee and unbranded) but i haclve the same issue. I wiped, advanced wiped with twrp reinstalled roms but same issue. I would appreciate a lot any advice.

Rooted Samsung I9000 sim card not detected

Hi All,
I've just got an Samsung Galaxy S that is coded to a provider network.
So far so good ...
After I've installed an application and root the phone and then unroot it, my pone doesn't recognize my sim card ...
If I navigate to the Mobile Network from Settings then I get No SIM card inserted.
Facts to take into consideration:
- I have restarted the phone;
- I have applied a factory reset and lost all my data except music and files I've got on it;
- I have shacked the SIM card a little bit;
- I didn't applied a hard reset to it;
- I did tried to put a different provider SIM card and the message I get is to insert PIN then is asking for the UNLOCK NETWORK PIN;
- I am able to log in the phone but with no service
Please note that when starting / restarting the phone I get no Insert PIN popup
Anyone has an ideea why ?
I've got the same problem saptaru.
No sim card is detected in my Galaxy S.

After dialing #*1234# I can read:

CSC:
I guess the IMEI cannot be recognized by the phone.
At least, I wrote it before rooting and flashing.
Any help will be highly apreciatted!
Hello,
After several restarts, hard reseting the phone and enable-disable networking I still get the sim card removed from time to time ... I don't really know how to debug this... if there is anyone on this forum with the right experience in order to debug the system please write me and maybe we can find a solution.
I must mention that I have unlocked my phone and also rooted it.
Thanks allot !
I have same problem now, can anyone help.
well my sim card has been identified but i can't seem to register on the network.....thats as far as i got as a noob with my first android (xperia x8)......can someone help me from here on......
i get nothing from sims from various networks, it doesn't even register as having a sim in it...
unlocked and darkys rom... driving me crazy, it basically a large mp3 player at the moment...
Maybe have installed the wrong ROM. i9000 has many bases and radios. I had this problem installing 900mhz ROM on a 850mhz sim.
Good luck

Have the same problem here. Have you managed to find a solution?
Hi everyone, I don't know if anyone is still interested but I've found that putting the phone into flight mode and then rebooting seems to work, because when I then turn flight mode off it asks me for my pin code and service is restored. As long as the IMEI folder is still in the efs folder then things should be fine.
Hope this helps for anyone who is here or just stumbles across this.
I've had the same problem > Sim Card not found.
I went to the Vodafone repair center today they said the phone had water damage.
Its never been near any water ever-they said that it could have happened months ago - "perhaps you hand wet hands once?". Its still in warranty but the apparent water damage means the warranty its now invalid. So now I'm stuck with an expensive video/audio player with WiFi access. Any help or progress with this issue would be great. Thanks

Device locking is done in the operating system, not the physical device. I have yet to see a custom ROM or ASOP to be sim locked.
Now keep in mind, the phone won't show APN's for other networks when you insert your SIM card. What is going on here is the device is reading your sim card to identify the provider then set the proper APN as default. To test if it's unlocked, try a different SIM in the device and see what happens.
Edit: I'm assuming you are talking about a SIM lock. If it's a lock of some other sort, please provide more details with EXACTLY what is going on.

Roaming-Not roaming
Mobile network state-Disconnected
Other informations:

This is NOT a sim lock. What is going on is that your phone has lost it's APN settings or is using the wrong modem. a sim lock means that your phone will only work with 1 provider, installing the SIM from a different provider will give you an error message similar to this: ‘SIM not valid’, ‘SIM locked’ or ‘SIM not accepted’
Since the phone is working on other providers, i would believe that the phone has lost it's APN settings for VIP. I would look up the APN settings for VIP and manually put them into the phone and go from there.
A quick search found a thread with the APN settings:

Try to flash another Radio. I never had luck with KF1, and quite frankly it kept me from getting any service at all for like 2-3 reboots after.
Try KD1, or KB3 (those work for me).
Reboot a few times, and see if it works.

Please help .... I have a similar problem. Writes that: No SIM card plugged in.

try checking csc via phone info.
Any fix to this?? I've just gotten the same problem on mine! Thought it might have reverted back to the region lock as I am now using a USA sim card and started off with a UK sim card. Just ordered a new UK Sim to see if inserting that one will fix the issue
Please .... Solution
Same problem here... No sim card.

I had this issue with my first Galaxy S6... I went into the three shop and checked my sim and that worked with another phone, but my phone would not accept any other SIM card. I was told to send to Samsung for repair, luckily I was in my 30 day amazon exchange period so I just sent back to supplier and bought a new one.
Same poblem here.. When i insert sim card, the phone restart and when enter in Android show message... "Error occurred while unlocking network... Network unlock code block".... Its a Japan Docomo network.. U think that can resolve it with a subsidy code? To unlock a sim?
Solution needed urgent

And if some one ask you about s6 the answer is dont say s6 its s sucks

Problems with mobile data s6 duos

Hi there,
Recently, I've been having mobile data problems with my s6 duos
I've got an s6 duos from globe, so 1 sim slot is locked to globe and the other sim slot is open line. Recently I've been having problems connecting to mobile data using my smart sim card. In the data service network, the option to choose smart for mobile data is locked/unavailable, so I can only use my globe simcard for mobile data. I've tried using a different sim but no luck.
I was able to use my smart sim for mobile data in the past. Though I have no problem receiving texts or calls with my smart sim
Advice is much appreciated
Thanks
Also, in APN under my smart sim, I get this message
"Unable to view the access point name settings. Access is restricted for the current user profile."
i64.tinypic.com/2i1kprd.png
My guess... flash BTU ... latest UK g920F firmware. Its kind of imposible to lock 1 sim and the 2nd sim to be unlocked.
Edit: you may lost warranty after this... and this is only my guess.
Edit2: flash a costom recovery... do a full backup so if something goes wrong you restore everything

Samsung Galaxy S10 (SM-G973F) doesn't register to network

I recently bought a used Samsung Galaxy S10 (SM-G973F).
At first glance the phone was in excelent shape. The SIM Card was connecting to the mobile network, and calls, internet connection, etc was OK.
But then, I found out that the phone had been rooted. Probably, by the seller. In pannic, I rushed to unroot flashing the stock Rom.
Here what I did:
1- Forgot to check my precisly CSC code and assumed ZTA (cause I'm from Brazil, and the phone is from carrier "Claro")
2- Downloaded the stock rom using Frija
3- Using Odin 3.14.1 flashed the device.
The previous rooted system was on Android 10 and One UI 2.5. With this new rom went to Android 11 and One UI 3.0.
The problem:
The phone recognizes the SIM Card. But it simply doesn't connect to the network. When I try to make a call it says: " not registered on network"
The phone DO recgonizes the SIM Card. On the SIM Card Manager shows my carrier name (Vivo) and my phone number. Also, the SIM app is showing on the app list.
Things I tried:
Rebooting the phone
Changin the SIM Slot
Testing the SIM on another device to ensure it was working
Checked if the IMEI wasn't missing/undefined. It is not, the IMEI appears to be untouched
Checked if the IMEI had been blacklisted. It's not.
Flashed SEVERAL different stock ROMS with different CSC (ZTO, ZTA, ZVV)
Try to manually select the network. This also throws an error saying "error while searching for network"
I'm really desperate and don't know what to do anymore.
No one have a clue either? :C
Look inside here:
How to Fix 'Not Registered on Network' on Android
Here is how to fix 'Not Registered On Network' error on Android. Mostly error occurs on Samsung phones, but this solution works for all android phones.
www.android-recovery.net
Wow,
This is exactly like my S10 right now.
At first, all is good, the signal was great, all working well, except cant connect to samsung pass and samsung health because it was root.
then i brought to sellular shop service, to flash the phone.
Then, “not registered to network” happened. The signal ok, the phone able to read dual simcard, but “emergency call only” and if i try to search network manually, “error while searching for network”
And the sellular shop service have no idea how to fix after they reflashed and try to fix it for several days.
Have you found any solution to fix your pho?
pls advice…

So, were you able to find a solution for this problem? I also bought a Note 9 N960F/DS recently and found out it was actually a N960N model that was changed to N960F/DS. So I did exactly what you did, I flashed the original stock rom, N960N, but now phone will not connect to network. I also did hard reset, reflash other stock roms, nothing changed. Anybody with insight should please give us some pointers.
