First of all, call your carrier and ask nicely, if your contract has expired, they'll hopefully unlock your phone for you.
If you tell your carrier you'll be travelling and wish to use
a SIM card from another country to save on roaming fees, they may also unlock your phone for you.
You unlock your phone mostly the same way you would if you were doing it through your carrier. You contact an unlocking service and pay their fee (usually between $20 and $30) and they send you a code. When you insert your new SIM card, you use this code to unlock the SIM.
You can also unlock screen code and sim-card of Blu Tattoo TV mobile phone. But you need to do first unlock code for it's operating system.
If the unlocking code is not working for Blu Tattoo TV, you need to enter your phone IMEI number to the box to get new one.
Typically all networks impose one, two of three limits on unlocking - time after activation to unlock, cost of unlocking and how long it will take to carry out. We'll explain how to do it on all the UK's major networks. There is no need to ever use a dodgy high street 'mobile phone unlocking' service - anything they'll do you can do yourself for a fraction of the cost.
