I cannot thank Simply Unlocked enough for such an excellent service. I rang the contact number to double check I would receive an MCK code (as I have spoken to both EE and Samsung for around 5 hours who didn't seem to know what I was on about!). I was told I would receive all the codes no problem I just needed to put the order through online which I did and I received the codes by email within an hour! I wish I had just done this earlier, it would have saved hours on the phone with both companies telling me it was nothing to do with them! Would not hesitate to use Simply Unlocked again. Thank you!
