[Q] Samsung S6 network unlock (O2 UK) - Galaxy S6 Q&A, Help & Troubleshooting

Hi everyone,
I'm in a bit of a mess with my Samsung S6. I've bought it from ebay and it turns out it's locked to O2. I've tried cellunlocker, unlockthatphone & mobileunlocked and they've all been unsuccessful when trying to provide the network unlock code - stating that the code isn't available for my IMEI.
Is there any other way I can unlock my phone? Or am I going to be stuck on O2 forever?!?!

I had a lot of trouble getting my EE locked S6 unlocked but in the end I found somewhere decent that was able to get the code in less than a day. I used http://www.samsungcodesource.com

How much did you pay to unlock it?

Just an update, I've now tried unlockunit & samsungcodesource as well and they can't seem to find a code either.
When I try to put a different sim card, I'm expecting something to come up to say that the sim can't beused due to a network lock, but nothing appears.
The only time anything appears is when I try to make a call and a popup appears saying "Not registered on network".
Does this mean my device is network locked? Or could it be a region lock or something?
Is there anyway to confirm that my phone is network locked?

Hey quill37,
PM, me I can have it rechecked for you, maybe it is possible to unlock it

Hi there, did you manage to resolve your problem. The same thing has happened to me. The bloke stated it was unlocked but its locked to O2 and am on EE. I've tried unlocking it but to no avail. Did you manage to unlock yours?

If you cant unlock by codes, buy the usb method here. Takes only a few minutes once the process starts
Also make sure your phone is not blacklisted. Check it using checkmend here

http://www.samsungcodesource.com have not sent me my unlock code after 72 hrs and they have not replied to any of my numerous emails

[Q] Help needed to unlock D2G

I've a Droid 2 Global purchased from a seller in US, which I'd like to use in India with a GSM SIM Card. It was used with Verizon Wireless and when I tried to use it, it requested for "SIM Network Unlock PIN". This sounded like the unlock code and I have entered the 8 digit unlock code he provided to me after contacting Verizon. But, when I enter the code to unlock the mobile, it says "Network Unlock Request unsuccessful" and prompts for "SIM Network Unlock PIN" again!
I've made sure the mode is GSM/UMTS (verified with Global also, though!) and tried with different GSM SIM cards. All those SIM cards work normally when used in other mobiles. I've tried contacting Verizon support 5 times, Motorola Support 2 times and my local GSM carrier support 3 times. It appears it was with Verizon. I've verified everytime that the IMEI of the phone and the Unlock code given to me match with the data they have! They wonder why this is not working, but they couldn't help.
I've tried installing custom ROMs too! The problem remains same! I've installed Radiocomm to see if I could try with the codes at "Subsidy Code" but it returns status as 00 (which means unlocked as per some other forums!!).
Can someone help me understand what exactly is going on with my D2G?
The unlock code for your device was changed at some point, or VZW's database information is invalid. It happens. In such cases the device is usually sent to VZW for a warranty claim (if you are a VZW customer).
Sadly, I am not a VZW customer. I live in India and planned to use it with my local GSM Carrier.
I've purchased unlock codes from some website too. They provided 2 codes which turned out to be useless. Is there a way we can bypass this from Radicomm?
No, there isn't.

[Q] newb needing unlock help

hi, newb here, having trouble unlocking my att skyrocket. i have followed the instructions to what i think is the "t" as they are very simple, but no luck. the only way i ever see "perso init is successful" is if after going back to network lock for one minute i go back again and hit #4 networck lock again "perso_nv_init is successful" comes up, but still locked. my model is a att samsung sgh-i727. android 4.0.3 baseband i727ucld2. kernel ver. 3.0.8-perf-i727ucld2-cl363164 [email protected] #1. build # iml74k.ucld2. any help would be greatly appreciated. thanks
I'd just buy an unlock code. If you try the free unlock too many times it'll permanently not allow you to unlock even if you buy a code. The unlock codes are not that expensive.
Ps, you can probably get the code for free from your carrier. This phone has been out for a long time.

You can buy a code online. All you need is your imei number. Just Google phone unlock codes

It is very true! If you attempt to unlock too many times then it will permanently be locked unless you send it in for JTAG reprogramming or to Samsung and pay the repair charge, but this is if you tried to unlock via just entering random codes.
In order to get to where you need to enter the code, you have to insert a SIM that is not with the carrier it is locked to, it will then prompt you for the code to unlock.

i have never seen or been asked for a sim code, when my tmo sim is in i get "mm6 error" or "not registered to network". if i type in something like *#7465#(i know thats not the # i just cant remember it right now)to get lock info, it all comes back as off. can mm6 error be for something else?
Sim Card
When I unlocked mine, you are supposed to put in a different SIM when you unlock your phone. Not the same one you use daily. Probably why it isn't working right...

Waht? Sounds like superstition tbh.
I had my daily sim when I unlocked mine at cellunlocker.net/samsung-unlock.php and all went fine.
OP: Try another sim.

[Q] Problems unlocking Rogers Samsung S3

I purchased an unlock code from Rogers, but when I enter it into the phone using the other service provider's SIM card, I get an error message that says "Network unlock unsuccessful". Rogers can't figure out why the unlock code isn't working. They've refunded me the costs, but I can't get it to unlock so now I'm without a phone. Anyone have any suggestions on what the problem might be?
Did you confirm that Rogers has the correct MEI number to that phone?
There are other options online too for getting the unlock code for your phone... since you're willing to spend money for it, you could try one of the respected unlock sites and get the code that way.. there is really no reason why the correct unlock code wouldn't work..

Alcatel OT 60451 Unlock code not working.

Hello all, i am trying to get my phone unlocked currently its locked to Telus Canada & Model ALCATEL ONE TOUCH IDOL 3 5.5 6045I .
Have tried 4 different sites selling unlock codes. They all provided me similar codes, one company provided 4 different codes and some 1 or 2 but the codes are same.
cellunlocker.net
Oneunlock.com
guaranteedunlock.com
canadagsm.ca
None of the codes worked, i have now 4 tires left. Tried factory reset before entering the code, have made sure that IMEI number, Provider ID and image Mapping (Secro / SRO) was provided. I even received SPCK code also but phone only asks for SIM lock code.
Anyone have any idea what could be going on, i am using windmobile sim to unlock it. This phone has never been activated on the Rogers, it was BNIB.
Thanks for your time.
Have you tried any eBay unlockers? I found this one: http://www.ebay.ca/itm/Unlock-Code-...116098?hash=item4ae66766c2:g:HuoAAOSw~1FUXz7Q
Thanks for the link, but they do not support this phone. Got an email back from them. Thanks
Did you ever get this resolved? I have a similar problem. All the sites I request an unlock code from give me a server error. Telus can't find the IMEI in their system although the UPC verifies it is a Telus device .
I used this site for my Bell Idol 3: http://www.mobifree.ca/

Usually, the vendor you purchase from will give you instructions. They're nearly the same for all phones. You put in a SIM card from another carrier and put in the code, or sometimes you have a number sequence first
sent from a phone running a ROM

Hi! Thanks for the help. I realised that you need to have your Wifi / Data turned on in order for the pop-up asking for the codes appear.
Although the codes that I bought didn't really worked...
I have never had to have wifi or data turned on for an unlock code to pop up. I've unlocked plenty of phones, including 2 Idol3 phones. All I need to do was power up the phone with a foreign sim inside.

need help tmobile device unlock app not working

Ok so I'm in tmobile prepaid.
I have a galaxy s10e that is was purchased full price from someone else. We verified everything at a tmobile store. The unlock was approved and i got the email approval. The tmobile device unlock app for this phone doesn't work. So I have to go to settings>network>more>network unlock
Or something like that. I get an error message that ends in 0x86
On both temp and perm unlock
I already went through it with tech support 17 diff calls. Nothing. Nobody knows what this error is. Ine tech guy gave me two sets of numbers. Both 8 digits. I believe these are the nck or unlock codes but my question or rather what I need help in is inputting these codes. I tried the generic ones I found online to no avail. The dial codes is what I'm talking about. Also when I reset with unlocked rom it still says to put tmobile sim. And doesn't give me a option to input unlock code that I have
I even called Samsung and they cant help me bc it's a tmobile phone. Tmobile doesn't know how to input the code when I do mention it. And yes I reset the phone put a diff sim. Tried with Abd w/o wifi. Everything.
So now I flashed the U1 rom on it amd the unlock options in the network settings is no longer there. Obviously bc u flashed the unlocked rom on it.
Any suggestions? Tmobile is giving me minimal help bc I'm a prepaid customer
