NetPal is truly a great service for all mobile phone users. I asked both EE and Sky for a 'SIM network unlock PIN' Which came up on screen as I wanted my new sky SIM in my old EE phone. Neither company's knew what I meant.
Using the code from NetPal I can now use my phone. The code was emailed to me the next day and I was kept updated as to the progress of my purchase.
I will be using and recommending NetPal for all mobile unlocks in the future!
Many thanks!
