N-920C Region lock asks for Sim network pin.
I purchased Note 5 model N-920C from Saudi Arabia but when I came back to India with an Indian simcard it asks for Network Sim Pin and if I discard it says invalid sim card or network locked sim card inserted.
Can anyone please help..
Thanks in advance
i have the same prob... anyone pls help
Saudi phones are region locked to prevent theft and black market sales. In order to unlock it you should insert a Saudi SIM like zain, stc or mobily and place a 5 minute call (whilst in saudi).

I bought my phone too in Saudi online but my sim works from my country in Philippines.. I did some tweaks on my phone but when I flashed a stock rom, it now asks for a network pin unlock ?. Help! (I don't know how to start a thread ?)
You have basically 3 options here to get rid of the region lock.
1. get a SIM from the country the phone originates from. Make a 5/6 min call to a mobile number. That should remove the region locking after this you should be able to use any SIM you like.
(note) You must call a mobile number from the phone and NOT a landline. And secondly if You do this procedure from outside the home country of the phone that call will be considered to be a roaming call and will cost more than a regular call.
This procedure is intended to be done to activate a phone with a local SIM while STILL in the country of origin and may NOT work if the phone was NOT activated with the original SIM of that country. It may be possible to still make this work by performing a factory reset and using the correct countries SIM card and performing the above procedure.
2. Look for one of the many phone unlocking web sites that offer a regional unlocking code and buy that code. (Note) the region unlocking code and the network unlocking codes are NOT the same thing so even after you have gotten rid of the region lock you may still have to get a network unlocking code if the original network operator has locked the phone to their network.
The code you need is the RGCK unlocking code. You maybe able to also get this code from the Samsung agent for the region the phones is from.
3. Speak to Samsung for the region that the phone was sold and intended to be used in. You maybe able to also get the RGCK unlocking code from the Samsung agent for the region the phones is from.
(note) this option will may require that you return the phone to Samsung for that region and they can remove the lock. This is likely the most costly option.
I hope that this info is of use to you guys.

Okay, so I'm pretty sure when I bought this phone with contract it was network restricted.. I changed my carrier yesterday to t-mobile, so I bought a sim unlock on the net. I received the SIM unlock code, I couldn't get to the input field though (I'm on CM10), but then I was playing with settings and I could successfully connect to T-Mobile, however the signal is weaker than it was before and it has disconnected twice, but still.. so I don't need the unlock code no more am I right? It was cheap so it doesn't matter, I just don't understand how can this phone can be unlocked.
Just curious, what was your original provider? I don't know specifically about T-Mobile, but some carriers allow other SIMs to be used, because they are sharing networks. For example, if you have a locked Rogers phone in Canada, you can use it with a SpeakOut SIM, because SO is riding on Rogers network. Could it be a similar situation for you?
But it's strange that you don't see a prompt for a network lock code when you insert a non-original SIM... I also had to unlock my phone by code, and I got the prompt right after putting in a different SIM. Could it be because you are on CM ROM? A general recommendation is to always unlock you phone from a stock ROM, before flashing a custom one. I am not sure about this, but just thinking out loud...

I was on Telenor Hungary, now it's T-Mobile, they are whole different providers, no relations at all. Well yeah, I've thought about that stock ROM thing too, but I still don't think it would connect to a different carrier because of the custom ROM. But it works strangely though, couldn't set up mobile net yet, and when I was on the T-Mobile hotline, it disconnected and the phone said the SIM might be corrupted.
So I tested, I can make phone calls, but everytime I reboot the phone I have to connect to the network manually from settings.. So I'm gonna try with stock ROM, and use the sim unlock code. Can I also use stock-based ROMs? Thanks.
Hello,
This is my first XDA forum post. And I am sorry for it to be about a trouble question.
I've recently bought a Xperia TL Lt30at that is AT&T from ebay.
Anyway, I am planning on using it in Mexico from time to time, since I live near the border, so I bought another carrier's SIM (Telcel) and was to unlock the phone.
But now that I called AT&T to get the Unlock pin number (for free) they told me the phone's imei was blacklisted.
Questions:
Can I still unlock it to use in Mexico with Tecel carrier even if the IMEI is blacklisted on AT&T?
and, Why after inserting Telcel SIM into the phone the SIM NETWORK UNLOCK PIN screen does not show? Do you know why this is not showing?
Could it be that the blacklisted IMEI is not allowing the Unlock pin screen to show after inserting another SIM?
Many thanks in advance

Thanks for the info. I've already done that and I checked the IMEI number, that is how after calling at&t to unlock my phone they notified me that the IMEI was blacklisted.
The phone has 10 unlock tryouts left.
Do you know if this is causing the phone not to show the SIM NEWTWORK UNLOCK PIN screen after inserting an invalid carrier SIM? Because I can reproduce this from any video I have seen.

no , blacklisted imei is not the reason ; when you insert invalid sim, what is happening? does your phone detect sim and is there any signal?

That is the thing also. I had a regular size SIM card from another carrier, I cut it using a template to fit the Xperia TL that uses MicroSIM (I tested that it still works on phones that use the regular size) and when I place it inside the TL it does not recognize the SIM like it is not there.
Could it be that I need to get a real MicroSIM from another carrier to display the SIM UNLOCK NETWORK PIN screen?

yes of course, you need good micro sim card, phone does not detect sim card because it is not well cut; if the phone works perfectly with other sim it means that there is no damage to sim slot; i also have got xperia lt30at; I cut micro sim using template and it worked fine; when there is no sim card detected, the SIM UNLOCK NETWORK PIN screen will never appear
Thanks for your help, I have gotten a new microSIM from my carrier and it works. Seems the other one was very old and not even cutting it would have worked.
Now it does display the SIM UNLOCK NETWORK PIN screen after inserting it.
Yo don't know if you unlocked it yet but I just unlocked one for sell n it can't be blacklisted cause all the networks have the imei number n it won't allow the phone to work?

I would like to purchase the GS6A from Amazon. It's without a plan but it is locked. Will I be able to unlock it in my country if I don't have any account at ATT's, etc?
How does that work?
You don't need a AT&T account for unlocking it. You can buy the unlock code form any unlocking website online.
My self using it in India bought from eBay and unlocked it later.
Note that it's not blacklisted or anything like that.
If you buy from ATT and pay retail price, they will give you the unlock code. Just call their customer service line.
Doesn't Make Sense
So, since I don't know much about unlocking devices, I asked AT&T Customer Support about it:
Me : After the 14 days: In unlocking the phone, does the phone have to be connected to the network actively at that time? What if I'm out of the country with the phone and want to unlock it remotely from some other location outside of AT&T network?
Karina : You will need to be within the U.S. to have it connected to our network to have it unlocked.
Me : I couldn't be on ROAMING at the time?
Karina : No, that will be since you will receive an email with the code to have it unlocked and need to be connected to our service.

So, this doesn't make sense, because the process for unlocking the phone is to turn it off, remove the AT&T SIM, put in another carrier's SIM.
Turn on the device and you should receive a message to enter in an unlock code.
Don't see why the phone needs to be present on the AT&T network first in order to receive the unlock code. What, do they send it via SMS or something?
1) My friend (U.S.) gave me (Canada) a T-Mobile Galaxy Note 4. I am trying to use it with Wind Mobile.
2) He claims that T-Mobile performed a carrier unlock, which seems to be confirmed because putting a foreign SIM card in does not ask for an unlock code.
3) My Wind Mobile SIM can't register on network. I tried a Rogers SIM as well and a different Wind Mobile SIM and they didn't work either.
4) The Wind Access Point Names have been entered, but manually selecting the network does not work either. It just says "Unable to connect, try later".
Am I missing something here? Is there another type of lock I need T-Mobile to remove? Do I need to flash the ROM? Thanks in advance.
If same sim cards work in other phones i would think that phone is blacklisted. On the other hand nowadays tmobile can issue temporary unlock codes for international travel. I dont know if Canada is considered international or not. Tmobile will permanently fully unlock device when paid off.
Have an used Pixel 5 here which was labeled as sim locked (carrier unknown ). I'm not sure if it really has sim lock or if the mobile connection is defective. When I insert my SIM it asks for the PIN and then the correct carrier is shown under network settings - there is no signal however.
How can I make sure it has sim lock and it's not a HW defect?
If it's locked - is there a way to find out the carrier which it is locked by?
More general - how is a sim lock indicated to the user when inserting a sim from another provider?
I've sent the phone to google for repair (Connectivity problem). They stated that no defect was found which would support the sim lock theory. Is there a way to know for sure?
If Google Repair team says there are no defects (assuming the team that handled it were competent), then it most likely is a carrier locked phone. I've never used a locked phone before so I'm not sure what to look for but if you can find out which carrier it's locked to, you could try inserting that carrier's sim card?
If you get a signal, then swap out the sim card to a different carrier and if it doesn't work, then it's definitely locked.
I don't know which carrier it could be looked to and how to find that out. When I enter the IMEI at the start of the repair process in the google store the device is identified as "Pixel 5 (128 GB, Just Black, without SIM-Lock)".
