How to save contacts in phone & sim on an HTC Sensation/Android?

I just bought an HTC Sensation and I’m putting my contacts in the phone but it would either save to sim or phone. My old phones that I had, had the choice of saving the contacts in sim, phone or either on both(phone&sim). So I’m used to that and it’s also handy if my phone is damaged my contacts are still on my sim or if I want to change providers which the sim card is different, I would still have all my contacts on the phone.

So I wanted to know how can I save my contacts to both phone&sim on the HTC Sensation or on an Android phone.
