I would recommend these people. I got an unlock code for £1.99 but needed a couple of email exchanges before I could unlock my phone as I needed to do a Cold Reset before I could get into the phone to... See more

FIRST CLASS CUSTOMER SERVICE

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.

excellent!

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.

Very good.

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

They Do exactly what they advertise....unlike others

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

BRILLIANT!

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.

Really worked!

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!

Worked where others had failed

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

fantastic service

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.

Perfect

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
