Highly Recomendend! My phone got network unlocked within 3 work days.

Ordered Samsung unlock code and received next day, worked perfectly . Code was sent by email , just send your IMEI number, fantastic service!
Thank you guys

Wasn't sure because I'm not very technical but very pleased by the service, finally have access to a UK phone, with a French sim card ! hurrah !

Excellent experience, i was a little worried in the begining but they have won my trust. Prompt email confirmation and responses. Would highly recommend to use their services. I will be placing another order with them shortly. Instructions to the point and were easy to use and within seconds my handset was operational with other networks. Time Order placed 11:25 am Phone Unlocking confirmation received at 7:35pm. Total time 8 hours and my handset was unlocked. Great job and thank you!!!!!!

Go with this company ... worth every penny. Professional. I tried cheap company who were crap and couldnt unlock it.
I jabe recommended this company to someone else already ... thumbs up!

After reading reviews on Trustpilot, and the No. 1 rating, I had no hesitation in deciding which company to use to unlock a phone I was going to pass on to a relative.

The ordering process was simple enough, provide the model and IMEI of the phone and expect a response in "48 hours maximum!"

Well, 48 hours later I had not received a response - nor an order confirmation. But I did have a receipt from PayPal, so I sent a query through the website querying the status of my order.

In the absence of any response from Guaranteed Unlock, I felt at this point I had no option other than to raise a dispute with PayPal.

And as if by magic, within a day I had my email from the company with unlock code and instructions.

I purchased a 99p sim from my local Tesco to allow me to verify if the unlock code worked once input. The instructions for my specific phone were a bit misleading and didn't work, so I resorted to the web to be able to enter the code. At this point, I finally had an unlocked phone.

I'm hoping I was simply unlucky and my order just slipped through the net, but it shouldn't have taken a PayPal dispute to resolve the matter.

Given my experience, I shall look elsewhere next time.

Unlocked my Samsung Galaxy Tab 2 within hours! I stupidly tried 'Official Phone Unlock' first but 30 days later I'm still waiting for a reply from them. I know now to go to Trust Pilot first and see who they recommend - which I shall always do in future. So, thank you GuaranteedUnlock because you've really made my day - one happy bunny.

Requested an unlock for a Nokia. Received communication promptly on how to get the information they required. Got the unlock code within 24 hours!!

Would highly recommend Guaranteedunlock.com for mobile network unlocks and I will be using them again!

code worked perfect and great price

Great job guys, It really helped me

Was done within the hour
Only costs £6.99
Have problems with 02 they had been trying to unlock my phone for weeks wish I had done this sooner

I am a complete numpty when it comes to IT and I had grave concerns that I would mess up the unlocking process because of my ineptitude. In fact, it took me some time to pluck up the courage to have a go but I followed the instructions given to me which turned out to be quite straight-forward. Although it took me a few attempts to access the right file that I needed to send off to Guaranteedunlock.com (as they had advised it might), I got there relatively quickly and the unlock code was sent to me a day later. Thank you.

Code supplied as promised. Well done !!!

Was worried about a possible scam but paid via Paypal made me feel more secured.

Received code within 48 hours ( weekend ) and it worked 100%

A fantastic company set apart from the others with their fantastic communication. A fair price when compared to other sites too but even if they were more expensive I'd be happy to pay the extra because of the fantastic service. Couldn't recommend more highly!

By far the cheapest and best unlocking website that provides great customer service.

Awesome job done

Awesome service and communication! Got it unlocked within the time frame that was given. Would definitely recommend!!

Order was filled promptly and the unlock code worked!

I had been searching the net and Amazon and Ebay for an unlocking service, and when I did reviews, I realised that you didn't know who were con men as most were. Luckily I found trustpilot and this company. It took 35 hours to get code, they had poor communication with me apart from computer generated PayPal messages, I started to panic and sent three emails and then heard from them with the code which worked great and no issues at all. So I did think it was a con site as no communication but it worked out great, would recommend to anyone. Just don't be in a rush, give yourself a couple of days to receive your code.

I needed to unlock my Sony Xperia Z5. I found this website and sent my payment of £18 and was told to allow 3-4 working days for my unlock code.. I got the code under 24 hrs later and it worked first time. So happy, thank you to everyone at guaranteed unlock. I will be sure to recommend you to everyone.
