Hi! I've got iPhone 5S locked to O2, I am using Giffgaff right now and I am completely happy with it but I have from time to time use Three SIM card which my employee provide to me to contact with our customers. Screen shows information that SIM card is invalid, tried connecting to iTunes (!) as you recommend but with no results, same thing happening. I tried "unlatching request" on your website but I provide you IMEI and my Giffgaff number, you replied that you dont have that number on your system. What I am suppose to do? Can someone help me? Please. Do I really have to buy O2 SIM, top it up (activate) and then ask again for unlock?

Yes, you need an O2 SIM so the phone can register on the system. https://community.o2.co.uk/t5/How-to-Guides/Unlocking-an-O2-phone-to-use-a-different-SIM-card/ba-p/1...
