The decoder is currently only for use in SA as the Activation USSD code only works on SA phone networks ...
However u can bypass this by;
1 Send ur STB no. and the satellite u using (IS20/SES-5) to a friend in SA and him do the activation there
2 DM these details to ovhd through Twitter and and they will do it for u
3 email me those details at firstname.lastname@example.org and i will activate for u (at a small fee of cause)
