[Q] Galaxy s6 edge sim unlock problem, please help

So i bought this sgs6 edge device from telus canada.
brought it back home, had the unlock code (also bought from telus and several sim free unlocking sites) and the device just keep poping up the same massage: "network unlock code unsuccessful"
tried every guide on youtube and on any forum i found online, nothing helped.
All the methods, through the dailer, everything.
Can someone please guide me how to sucssesfuly unlock my device?
Many thanks!

Sounds like you got a bad code. You should request a refund and buy one from another vendor. Be careful entering the code too many times. After 10 (I believe) it locks and you can never sim unlock it.

Is the phone paid in full?
The only reason I ask is that I bought an AT&T Nexus 6 shortly after they were released. That's the only Nexus not sim unlocked and my condition on purchase was for the seller to unlock it. We met at an AT&T store, I popped in my Verizon sim and the seller gave me the code. I tried it a few times but the code kept coming back unsuccessful. He called AT&T for the correct code and lady told him she couldn't give it to him because it wasn't paid off (although they had previously given it to him). After some conversation, he eventually gave them his CC # to pay it off. They then provided the exact same code. I hesitantly tried it again and it worked.
I also recently learned that the T-Mobile S6 Edge doesn't take an unlock code at all. It must be unlocked by T-Mobile or it can't be unlocked at all.
Perhaps the carrier is somehow keeping it locked front their end?

So you simply say i have to call them and fully pay it off, so they would relese some sort of lock they have on the device and then i would be able to open it with the exact same code?
If thats true thats might work. I'll try it and update for any changes. Many thanks!

Hey man, my phone is fully paid in. I talked to telus and they said the sim unlock is aprooved in thier computers so what is the problem?

Incorrect Unlock Code from AT&T

Hi, I like to know if anyone else has the same problem and what options there are if any.
I bought a new AT&T Note 9 on Ebay. Seller told me the phone had been paid off so I went ahead and requested an unlock code from AT&T.
AT&T approved my request and provided the unlock code. Problem is that I kept getting message that the unlock code is incorrect. I have tried 3 times already and still got the same incorrect unlock code message.
Upon further research, I found that one may have up to 5 attempts to enter a code to unlock the phone. If entering incorrect code more than 5 times, the phone will be permanently locked to the network, in my case to AT&T.
I have been given the run around from both AT&T and Samsung. One says the other should be responsible for fixing the problem (!!!!).
Any advice is appreciated. Thank you.

Go to cellfunlocker and buy code..they will give you all codes you need

First question. It's an important one that you need to answer accurately. Did the original owner buy it from ATT or Samsung ?

Seller told me that the phone was purchased from AT&T and paid off, which seems accurate because AT&T already approved my unlock request even though the unlock code does not work.
Now with the blame game AT&T and Samsung are playing, I am not sure what else to do. Last resource will be to pay and get another unlock code from 3rd party.

I'd suggest cutting your losses and going the route as the person above mentioned using simunlocker net. To be honest.

I ran into the same issue. Apparently it's a common issue and one that ATT is not moving quickly to fix. I just bought an unlock code from cellunlocker. Now I just have to wait. Irritated since ATT is is supposed to do this for free and I already waited once for their useless unlock code. Now I have to wait for another one.

I submitted a request last week for a lock code from AT&T, then later that night said screw it, and purchased one from Cellunlockers.net. 2 days later, AT&T sent me the code (same one from Cellunlockers), and it was in the correct 16 digit format. So it looks fixed now, but you still have to wait 2 days. $25 gets you the code in a few hours. So I guess it all depends on how patient you are.

Must not be fixed for everyone. I requested a code from ATT last week and received the 8 digit code. I tried it again last night, and they sent me the same 8 digit code. Not sure why some are getting the correct 16 digit codes then. And its a wide spread problem if you search the forums. Even ATT's own support forums, and people there are saying the only solution is a 3rd party.

Both. I'm using it on T-Mobile, but need to leave the ATT firmware on it to unlock the SIM first. Then I'll flash either the U1 firmware or the TMo firmware. Haven't decided which yet.
The first Note 9 I bought was a Verizon model off eBay for $690. Two days later the seller "made a listing error," and meant to list it as a brand new ATT version for $900. He forced me to cancel the listing and issued a refund. Which has since been denied by HIS bank, so I don't have the device or my $690.
In the meantime, I found this ATT variant, which is mint condition, like new for $560. They listed it parts only, because it MIGHT be locked to a carrier. Before I purchased I verified it was clean, clear, and paid off and eligible to unlock. Now just dealing with getting the correct unlock code. It cost me $22.50, so I'm still in this for less than $600. So it's all good.

Sounds good. Hopefully the phone won't turn out blacklisted a few months down the line. I think you might be happier with the T-Mobile firmware due to functionality like RCS messaging etc. I believe wifi calling works on the U1 firmware but that's it. For Sprint anyways.

I don't think it will get blacklisted. If it does there's always PayPal buyer protection.
I don't use RCS, since I use Google Voice for my primary number, so I'm stuck with Hangouts anyway. WiFi calling worked on the N950U1, so I assume it will work on the N960U1. Seems like the signal was maybe a little better with the TMB firmware, but I cant remember for sure.

It worked!! Less than 12 hours later and I had a 16 digit code. I'm now running my T-Mobile SIM without issues!

Hi guys, quick question... Im about to try cellunlocker. My phone is Note 9 960F dual sim. So it comes with two IMEIs... which one do I give to the website? SIM 1 or SIM 2?
ive tried switching SIM cards between SIM 1 and SIM 2 and wherever I put the different network simcard, thats the one that is grayed out and stuck on 2G only. So either I have two unlock both SIM slots or maybe just one slot/ IMEI?
Thanks

It's a mixed bag. Some people got the full 16 digits. In my case on two separate ATT Note 9s, I only received 8 digits from ATT, so I had to get the correct code from cellunlocker.net, which was 16 digits.

i think you can unlock one slot to use it on another network. if you want to use two SIM cards from different networks so you have to unlock both.

Thanks! Will try unlocking SIM2. Thats all I need anyways

If you can figure that out you will solve a 7 month old mystery. From what I've seen, ATT blames Samsung for giving them the wrong codes, and Samsung says ATT is providing the wrong codes. Either way, 3rd party vendors are able to get the 16 digits codes without issue.
Before the Note 9, Samsung phones used 8 digits codes. So it seems ATT did not update their system to provide the full 16 digit number. The number they give you is the first 8 digits, as though the full number was truncated by ATT's system. It just doesn't seem to be a priority on ATT's part to fix it.

Factory unlocked but it has a regional lock

Hi all,
Recently I bought a NOTE 9 SM-N960F/DS 128GB (FACTORY UNLOCKED) 6.4" Exynos. over ebay during Thanksgiving.
I never activated and I thought it is network unlocked as well but when I came to a different country and inserted a new sim it saying "Invalid sim car" and asking to enter a unlock code??
My seller not responding and also it crossed grace period to return.
Samsung support says I have to call Malaysia at least 10 minutes to unlock it which is not possible to for me to travel there.
ANY HELP IS GREATLY APPRECIATED.

File a claim through PayPal and get your money back.

I got my Note 9 direct from Samsung, there was a warning on the box (the actual seal) it states it was made for the European market and to use it internationally first a European operator SIM needs to be inserted and make a total of 5 minutes of calls before it will unlock for international service providers.
So it's not that they are region locked it, they are just trying to make them stay in the market they are intended or sold as second hand.

Network Unlocked but gives Invalid SIM outside USA
Hi everyone,
I recently purchased a Sprint Note 9 SM-N960U which was advertised as Network unlocked, but when I received the phone in Qatar and inserted my SIM it gave me "Invalid SIM". It often gives me " Insert UICC that came with the device". Can someone guide me to how can I unlock this phone? Also I need to know do I have to root the phone to Unlock it?
Thanks and regards,

Your best bet is to call Sprint and pray the phone is paid off and they will unlock it for you.

Looks like is sim lock and you need to unlock it. Try on Google note 9 unlock and use a reputable site see if it helps.

Are you talking about region lock or carrier lock? If region lock, then I believe you need to make a 5 minute call from the region of purchase. If talking about carrier lock, then either your carrier or one of those third-party online unlocking services should do it.

i want to ask this.... what should i do before travel to usa ir order to use my note 9 over there? the phone was bought
and are being used on chile actually.

I am talking about the regional lock, I am no longer in that region to make that phone call, and don't have a sim card from that region either.

The region lock cannot be unlocked with a code. You are required to use a sim card from UAE and make atleast a 5-10 minutes phone call through the sim card from UAE. To remove the region lock.
This lock is on the phones temporarily, to prevent the phones being sold outside UAE and same with other countries.

I don't think so. Since lock is most likely hardware based, which is why you gota do the phone call for 5-10 minutes for it to unlock.

Yep your right there is no way aorund without the 5 min call!! His only option is, he will have to fly back to UAE and make the 5+ min call, that's your only option! Alot of people have run into this issue, it sucks!

Major bummer. I remember when Samsung introduced the regional locks, was it on note 3 or note 4 days?
I dont think USA ones are region locked though.
Hopefully the OP can post his note 9 to the UAE and have someone do the 5 mins call for him.

It was introduced during the end of the Galaxy SII's life cycle. So around the SGSIII's release. But it could be easily bypassed by making a 5 minute phone call after you have registered your device with Samsung after putting your SIM into your device.

That isn't a bypass. If you bought a phone in like Sweden, then you must do a 5 minutes call in Sweden with a swedish sim card. Then the lock will be removed.
Samsung have made it like this so phones sold in etc Sweden, Norway and Finland it cannot be used outside these countries if it's sold outside. Same with ones sold in USA will be region locked in USA until you do a call there to with a sim card from USA. It's a protection to prevent China or other countries selling other versions of the phones.

Yeah. But once you have made the call. You can use your device anywhere in the world. Allot of Grey Import Retailers do the same thing when they sell their devices.

I managed to solve the problem using Dr sim website, costing about 20 bucks, thank you all for your help

If you live in Europa just go to the nearest Samsung service center with the phone and proof of ownership, I'm not that lucky as I live in USA and my phone is from Singapoore = 0 help anyways, i tried 3 different 40-50 USD online lock removal programs without luck, i did get the money back as they were unable to remove the regional lock , so Here's how I fixed my "out of region blocked" Samsung note9 bought at Amazon.com USA: I found a nice person in Singapore there could mail me a used postpaid Singapore sim card with a few $ on it, I installed the fake gps position app and made my phones gps think it was in Singapore, installed the Singapore sim card and couple of fax numbers out there I found on the internet (no answer no charge) and left the note9 on data roaming overnight with the 2 dollar Singapore sim card in slot 1, restarted the phone a couple of times overnight insured the gps showed it was in Singapore, in the morning I shut down the phone removed the Singapore sim and mounted my US Tmobile and Mexican Telcel sims and started the phone, sim card showed me and us numbers and all worked now as normal with wifi calling and Volte and now with the latest updates etc. so I guess my way to regional lock removal worked as I was out there in Singapore using my phone for a little while and hereby removed the lock.

Struggling to Carrier Unlock - L09 Vodafone UK

Hey guys,
Looking for some advice on unlocking my device. I bought it of marketplace and it seems to be locked to Vodafone UK.
I'm having no issues at all when using a Vodafone sim and adding a new SIM prompts for the network unlock code (Expected behaviour) but I've tried 4 different companies now to try unlock the phone and each have said they can't find the code on their database?
I thought the IMEI might have been altered but it's aligned with what's on the box and legit.
Can anyone offer any advice on what to do next!? Cheers

Yeah I've spoken to them, they said they can only help once I put a sim in the phone for over 30 days (I'm now 2/30).
Id just hate to wait 30 days for them to not be able to do it!

cop out but check ebay for vodafone unlocking codes usual takes alot less time. if you bought the phone second hand and as long as its older than 3 months it can be done. all comapies will say it can take upto 28 days to get the code but thats just to cover them.
just a quick look but this one says huawei
