To liberate your Phone You will need the following:
Your phone's IMEI number: It is your phone's identity, like a serial number or a fingerprint even. Most phones have a 15-digit number written in fine print on the back of the device. You can also find it by dialing *#06# into your phone's dialer app, or go to the settings and then the About Phone section.
A SIM card from a different carrier other than the original provider: A SIM card is how your device connects with your wireless provider. It is also worth noting that O2 is the same network carrier as giffgaff CTIL, Weve and Tesco. EE is the same as Orange etc. If you change out one SIM card for another that uses the same network then usually you will not get the automatic unlock code prompt. Normally you can switch to these other carriers without the need to unlock your phone.
What is Unlocking?
Cellular phones are expensive technology. To help make them more affordable to new customers carriers like Vodafone, EE, O2 and O2 (/ O2 UK)would commonly offset the cost by locking a phone to their network. Instead of paying £700 for a new phone, new customers could pay £0 down in exchange for agreeing to a 3-year contract which had the price of the phone built into the monthly payments. The phone was then 'locked' to the network so even if you ended the contract, the phone would not work with competing services; forcing you to buy a new phone.
Unlocking a wireless device lets your phone work on any network that has compatible technology.
Why Should I unbar My Cell Phone?
