[Q] SM-N900T 4.4.2, rooted, region free, still region locked

I have a T-Mobile USA SM-N900T currently running [ROM][KERNEL][4.4.2-NE4][SM-N9005]CivZ_FlexKat_Rev3.5
The ROM is listed as "region free" however when I attempt to insert one2free Hong Kong prepaid SIM-card I got a 'network locked sim card inserted' error?
I can't use "Region Lock Away" as it's no-longer functional on 4.4.2 - and I can't downgrade to 4.3 because I assume my bootloader has already been upgraded.
Any solution here?
Shouldn't a "region free" ROM no longer enforce the region lock?

Check out this rom: http://forum.xda-developers.com/showthread.php?t=2487425
It is region free but it's a N9005 custom rom and it works fine with a N900T Note 3
phone. The only thing which it will lack is wifi calling.
After flashing the rom you will need to flash the wifi/nfc/bluetooth fix in recovery
in order to get the wifi working. (not wifi calling!)
Here is the link to the wifi/nfc/bluetooth fix zip file: https://dl.dropboxusercontent.com/u/45687485/Needed_Files_BT_WIFI_NFC_Flashable.zip
Good luck!

Same results with this ROM Boots to a "Enter SIM unlock key", and "Network locked SIM inserted" screen.
I don't understand - as my understanding was the region-lock was only for the INITIAL activation of the phone in it's home market, IE it was activated at some point in the US with a US sim!?
It would figure now that it has been rooted/ROM replaced it wouldn't region lock again?
The phone did have a black-listed IMEI - but worked on roaming here with my US sim prior to porting the number to Google Voice smh

region free and sim lock are 2 different things.
sounds like you need the sim unlock code
I used freeunlocks.com,you have to do a trialpay thing but there may be one that suits your needs?
cost me just under £5 and I got 4 unlock codes,network,provider,sub-provider and defreeze.
my phone is now sim unlocked and sim unlock also does region lock

Hi,
I had the same problem with my European Note 3 when going in Israel.
The solution was to unlock the phone by using a European sim and calling somebody (for instance your voicemail) for 5 minutes or more.
Then it was unlocked...
Try it if you have an American Sim somewhere...
Hope it will help...

Thank you, I'll give it a shot.
I went to a Samsung Service Center (in Hong Kong), and they told me I would have to get my "American Carrier" to unlock the phone and that they could not help me.
As I am not a customer of T-Mobile USA anymore I don't think there is much I can do- as I don't think they will help me over the phone or would have any idea what to do at a normal T-Mobile USA store.
I might try to find an American Pre-paid SIM and try that option.

Unlock AT&T Samsung s7 edge?

Is there a FREE way to unlocked the at&t version of the S7 edge? The phone is still financed but I want to be able to unlock it and avoid it being blacklisted.
Please, if anyone can help, I'd greatly appreciate it!

No. Pay $14 and you get it unlocked.

My experience :
I unlocked my device from a website ( simunlock - 18$ ) and placed a european carrier sim card. Everything worked , the phone worked as described.
Then i decided to remove AT&T software and instal the U version , didnt want to use all the bloatware and carrier specific stuff. When i place my sim card to the new U phone i think my phone locked to the new carrier. Will try tonight with a different sim card and will write back.
My thoughts after all are that if we instal U firmware on AT&T Phone i think that will unlock the phone and then lock it to the new carrier
After all this all might be just nonsence , so i'll test it tonight.
Out of the box setup:
Insert the SIM card before you set up the customer’s device for the first time.
Samsung Galaxy S7 edge | S7 locks to the carrier of the first SIM that is inserted by resetting and installing carrier software. If you set up the device and then insert the SIM you will have to set up the device again.

My phone was paid in the full the day I bought it. Called AT&T and they unlocked it for free since I own it free and clear.

I believe the unlock is tied to the imei number. Not sure. It should be unlocked permanently no matter what fw is on it.

For my own clarification you're talking about carrier unlocking and not unlocking the boot loader right?

Galaxy S8 US Cellular

Hi .
I have bought a S8 locked to US Cellular on eBay, clean , not blacklisted and when I try a SIM card from my operator does not ask for unlock pin code and remains without registering on my network.
Does anyone know any website or any method to unlock It?
Many thanks in advance.

Does it have a unlock app in apps drawer or in settings. It may be unlocked. If ure sim works. WhT carrier you on.

Thanks for your answer.
I live in Portugal and I tried 2 different SIM cards. The phone shows in upper left screen the message "SIM blocked". I searched for an unlock app too but I can't find any like in T-Mobile phones I bought in the past.

US Cellular is a CDMA network provider whereas in Portugal you probably have only GSM networks.
I think you should look into this and investigate this issues as well.

Another info: I flashed with Odin with the latest USC official Rom from sammobile. Can be this the cause?

This is 950U version and therefore has the GSM frequencies as well.
Even if it was only cdma it would prompt to insert the network unlock code....

Any help?
WHen I put a sim card it appears a forbidden sign on the top, where I should see the network signal...
