If possible, how can I put my contacts on my SIM card?

[iMore Question]

I have a model A 1303, with 16gb, os 6.1.6, I don't know how to put my contacts on my sim card. I would like to do this so I can use a different iphone 3 by just switching my sim card to another iphone 3. [Edited] DO NOT POST YOUR PHONE NUMBER.

You can only import contacts from your SIM to be used on the iPhone, however, the iPhone does not natively write to the SIM card.
