Company Details

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.

Я разместил заказ, через час со мной связались, уточнили детали. Через четыре часа я плучил требуеые мне кода и точную инструкцию как пользоваться.Все подошло, телефон работает! Спасибо! Thank you! Novikov Igor

I recently used this company to unlock an old Nokia 6700 Classic. As I couldn't unlock the phone, GuaranteedUnlock refunded me within 12 hours of receiving my email. No quibbles - no fuss, just great customer service.

I'm very happy now i can use my phone normally..Ijust inser the key network one time and then it,'s started working imediately.I super recommend thank you.

It was a suprise quick reaction after payment in 10 minutes I received the code wich was working perfect. I am sure I will be back whenever I have similar query.

I chose this site because they were the cheapest out of competitors for EE, but could not unlock with EE. The unlock was an easy process overall. The projected time was 10-12 days and after 7 days I asked if there was a specific date I could expect it- a few hours later it was unlocked! very pleased with the service, would definitely recommend.

Code arrived within the hour, and my elderly Motorola L6 was working with a non-O2 sim. Thanks very much, excellent service.

I have a Sony Z5 premium which was locked to O2, I did as I'm sure many have searched every company on Google to unlock the phone..... I paid 4 different companies over one week who claimed to unlock any phone on any network who for some reasoncouldn't unlock my phone.... No reason given just an apology 24 hours after my orders were placed and paid and full refunds within 10 days so no rush to pay me back my money! Then I found this company who claimed the above but much more costly than the others I was hesitant but needed to unlock my phone however I was quickly reassured by the company that they WILL unlock my phone and they sure did within 3 days with a code that worked straight away 1St time no issues. Thank you for sticking to your word, really do get what you pay for a guaranteed unlock code no messing around!!! They say buy cheap.... Buy twice so it definitely pays to pay a little more for the best I will happily spread the word about your company to others who require an unlock code

I found this firm on a websearch. Very clear ordering instructions and excellent value. The unlock codes were emailed next day and worked perfectly. Phone now working fine on Tesco network.

I'm always spot on the ball when it comes to paying for anything over the net. After checking this site out I took the chance and yeah it paid off. These guys are simply brilliant in the service they provide! Buy with confidence is all I'll say. Many thanks to Zico for the unrivaled help and support.

I was a bit worried about using a online site but after reading reviews on trust pilot i decided to try it. What a fantastic code site. Got my code withen hours and it worked first time. No problems. 5 star rating. Would definitely recommend and will use them again. Price was fantastic too compared to my local repair shop.

I will recommend it to everyone one best company out there. thank you so much guaranteed unlock Team. I Will use it again

Unlock code received within the time stipulated and it worked, unlocking my Galaxy S4 which was locked to O2. I obviously would have preferred to pay less than the £17.99 it cost, but after reading terrible reviews for other websites which charged £1.99 etc, I decided to go for guaranteedunlock.com and am pleased I did! Would definitely recommend!

Took a few days to deliver but worked like a dream first time.

I was having trouble unlocking my phone, I had shopped in many other places online which all failed to unlock my network, Thankfully I found this site which unlocked it within the time period they stated. Thank you very much to the guys at garenteed unlock

The process was quick, and code works in one go! Thanks heaps :)

Code work . Will do more on this site Thank you.

Good price, code arrived in time, worked at first try! Good and detailed instructions! Excellent work!

After ordering a code elsewhere and not getting it, I came across guaranteed unlock. This company were fantastic from start to finish. I must admit that when the code arrived I had doubts as to whether it would actually work, but it did, first time. It does exactly what it says on the tin. I have also just performed a software update and thought it might revert back but no its still working. Thank you for setting me free.

It's rare that I leave reviews, however after buying what I thought was an unlocked iPhone I discovered it was locked I tried another company who after 4 days didn't get back to me then tried guaranteed unlock This company are absolutely amazing, they found out the network lock and unlocked it all in one day ! Amazing service and all for £21.99 Can't rate then highly enough And will always use them if I have a problem like this again
