How do I do it?

I will generate the codes using the IMEI of your phone, network and model. The IMEI of your phone can easily be obtained by pressing *#06# on your phone. You will then receive an email with instructions like the ones that follow:

1. REMOVE SIM Card
2. Power Phone On
3. Type into the phone the code FOR EXAMPLE #pw+9876543210+1# - do not enter this code it is an example - each phone needs a unique code.
4. Press the * key a few times to get the p, w and + keys
IT REALLY IS AS SIMPLE AS THAT

Why have my phone unlocked ?

Unlocking mobile phones basically means unrestricting the phones potential to use any network.  An unlocked phone can use any SIM card from any network, from any country.  Ideal if you're planning a trip to another country and would like to use that country's local SIM card.  Or you have a new phone but would prefer to use your old SIM card on a different network.
