Some testimonials

Excellent Service Written on: 07-01-2016 by David

I entered the Make and Model on the very easy to use website and then entered my IMEI number when prompted. Within 2 days I received my unlock code for my Lumia 535 which has worked perfectly. Great service and a company you can trust.

Went to Mobile Unlocked having found them through a GiffGaff unlocking Wikipedia site and they had loads of good reviews so thought I would try them out to unlock my Samsung Galaxy S5. Filled in all the necessary details and paid through PayPal (handy and safe) and sat back to await my codes. As I'd ordered them at a weekend I wasn't expecting to hear anything until a working weekday but got an email the very next day with my codes. Found the instructions slightly confusing as wasn't quite sure which number was which but a quick look on the website confirmed things and lo and behold my phone was unlocked forthwith. They offer a money back guarantee if they cannot unlock it and for £19.99 for my phone it certainly beat the High St quotations. Have already recommended to my daughter who has an S6 to unlock. I guess as already mentioned above, knowing the format of the codes sent would have been useful as they as labelled rather obscurely but their website made things clear.

Straightforward & supportive! Written on: 02-03-2018 by grtc23

I needed to unlock my HTC. The process was very easy even after I made a mistake and gave them the wrong IMEI!! Their support desk kept me up to date with everything and solved my self-inflicted error with the minimum of fuss. Highly recommended and very well priced. Thanks!

Exactly what I'd hoped for Written on: 13-07-2017 by --

The service was very quick, my phone was unlocked within 10-15 minutes after paying. Excellent stuff, will happily use this service again if I have another locked phone.
