Default [Q] Using a MagicSim for a Samsung Galaxy Note 3 with a Telstra Phone

Hi Everyone
I recently signed up with Telstra for a Samsung Galaxy Note 3. I have a work number and a personal number and don't want to forward the calls. I bought a MagicSim Elite Duel Sim adapter. Unfortunately when I have put everything in its right place it says No Sim. I have taken it out carefully and reinserted several times with no luck.

Telstra say the phone is unlocked but it is not recognising the MagicSim Duel Adapter.

Any Advice?

Thanks
