Can anyone assist, I'm after an unlock code for a 6230i, so I can use an O2 sim.

1. Insert a non accepted sim, most times it will show "Phone Restricted"
2. Press the UNDO option
3. You should see a box that says enter restriction code.
4. Enter the code given and then press (OK)

 

You're the man!

 

Thanks for the reply
Glad the code worked for you
