Need MCK code to unlock my Samsung Note 10.

aaibaba2024 — Thu, 06 Feb 2025 10:15:41 GMT

I am in the loop. please help.

called EE to provide unlock code which doesn't work.

Asks for MCK code.

The called Samsung as advised by EE support. Samsung advised their phones are unlocked and the lock is put in by EE. So they asked to call EE again. Very frustrating experience!

This is never ending. Please can someone help?

Afternoon @aaibaba2024

Thanks for reaching out to us on the community.

If you need the MCK code, please try the below steps using the device keypad.

Enter the last 8 numbers of the 16 digit unlock code, then enter the first 8 numbers of the unlock code.
Please restart the phone and this should be unlocked for you.

Does this unlock the phone for you?

Thanks.

Leanne 🙂

Hi,

We tried that but then still got message incorrect code and now we are locked out of the device asking for MCK Code.

It happens only when we insert SIM card of new provider which we are porting over. If we use EE Simcard, no issues. So after googling and speaking at least 4 times with EE Support and 2 times with Samsung support, we believe this is EE Issue. The 8 digits code they provided don't seem to work. The IMEI input online comes back suggesting device is unlocked. But we get MCK message when testing with any other SIM Card.

How we do resolve this please? This is frustrating, as we have already started our contract payments with other career.

Thanks

By the way we were only provided with two 8 digits codes and the EE rep suggested trying either of them. Not in the order you are suggesting. So not sure. Looks like we need full 16 digit code to begin with? Thanks

And just to be clear: Initially when we put another sim card it asked for Network Unlock Code. Which we input based on what was provided by EE rep in two parts as mentioned below. Since it did not work, the error message now says- too many attempts. please enter MCK code.

Hi @aaibaba2024

Thanks for coming back to me.

If you enter the IMEI number in the Device unlock form do you get the 16 digit unlock code?

If this doesn't work, I would advise getting back in touch with our tech guides to see if they can get this looked into further for you.

Leanne.

Hi,

This is the scenario/experience:

There are two IMEI no for two slots. Slot 1 has EE. When we enter IMEI for the same in the link you posted, it says the device is unlocked already. If we try to put a new carrier SIM in this slot, we get an error message on the mobile asking fo MCK Code.

When we enter IMEI for slot 2 in the link you posted, it says:

Sorry, something went wrong on our end. Please enter your IMEI again or come back later.

The device only seems to accept EE SIM Card.

So we are stuck.

Can you suggest who/how to reach out to the tech team? Thanks

Thanks for the extra information @aaibaba2024

If you have an EE SIM to call off, 150 will be able to help get you through to the right people to escalate this.

Hi,

Tried that route at least 5 times only to be put on to Samsung or not giving any answers.

Hence started this thread suggesting I am in the loop. I can't believe EE Tech can't resolve this issue in Todays' world. Porting over should be a simple process in most cases. Can you suggest any other solution?

Hi @aaibaba2024

Did our technical support guides provide the unlock code for SIM slot two?

Could you try the unlocking steps using the second SIM slot to see if this works?

Thanks for trying!

EE tech support gave us two separate 8 digit codes on day one, which didn't work, neither for slot 1 nor for slot 2. They in fact told us that code is same for any slot!!!!!!

Went to the local EE shop, the rep their was very helpful but all she could do was call EE tech support again and escalated. The support rep on the other end of the line promised me that she has escalated and someone from tech team will call us within 24 hours. Nothing to date!

We have now paid £40 for online unlocking services (third party) as last option and waiting for the process to complete. We shouldn't have to as phone is out of contract and clearly EE should have provided us with the unlock codes. TWO WEEKS and still counting...

We hope we never have to deal with EE ever again. Worst tech and customer service experience! Sorry!

aaibaba2024 — Mon, 10 Feb 2025 19:52:23 GMT

By the way, can you please advise how do we raise a complaint against EE to the telecom authority? Unfortunately, we are left with no choice, but least our complain will get the attention from the relevant authority in EE and hopefully no one else in the future will have to go through this.

Thanks

Hi there @aaibaba2024

I am very sorry the team have been unable to get the device unlocked for you and I understand how frustrating this would be,

You can find ways to make a complaint on our Make a Complaint page.

Hope this is sorted soon for you.

Leanne.

It's still happening. The tech team didn't even know what a MCK code was. They've told me they need to contact Samsung, which can take up to 7 days 🙄. But in the mean time, they've "cancelled" my complaint, and will contact me when they have an answer......Im betting they'll washing their hands of it.

Hi @spacemonkey1981

While we generally hold the unlock codes for all our devices, we don't have to access to the Master Control Keys, which are generated by the manufacturer. These would need to be requested from the manufacturer and usually take a few days to receive them. I'm glad to hear our technical/Unlocking team have requested this for you.

Keep an eye on your email and spam folder, as replies are usually sent by email if they are unable to reach you by phone call.

Just so you know, while the complaint may be temporarily closed while waiting for a response from the manufacturer, it can be reopened at any time within 28 days. Keep a hold of your complaint reference number should you ned to refer back to it.

Hello Ali,

As I originally stated, customer support had no knowledge of what a MCK code was, or any options on their system to deal with it. They had to google it. So unless the EE agent personally wants to take the time to research and resolve the issue, it won't be.

This community has a number of posts with others who've experienced the same issue, and EE washed their hands of the issue. As for closing the complaint, it doesn't matter if it's temporarily closed as EE won't follow up or chase the issue unless the customer gives them a kick again because it's closed. Just makes EE's stat's look good.

@spacemonkey1981

Was it only the technical team you spoke to, or the dedicated handset unlocking team?
