Move ALL contacts to SIM card in NAND ROM?

---

How can I do that? Please could anyone help me with this?

Si this is impossible? LOL

I do not have the option on the ROM I am running and I don't think I have seen it on any ROM I have ran. But what I do is have all my contacts synced with my Google account so when ever I flash a new ROM and sync up they are all there once again. So I don't think this is an option...that I have seen.

if you use a sense rom u get the option to view sim contacts save them to the phone then save them to ur Gmail account,

Download Contact2Sim from market.
