It does not respond at all:
SIM-kaart plaatsen (place SIMcard)
I enter the code:
#pw+946902765412367+7#

And the complete code stays on screen
What do I do wrong?

 

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)

 

Thanks, it's accepted.

 

Your welcome

 

Maybe a stupid question:
How do you determine the used box serial?

 

Alot of time and research
