6630 Japan and old sim card??????

Hey you all guys????
I don't know why but I heard somebody has successfully using a different networks sim card @ philippine with Nokia 6630 Vodafone 702NK without unlocking it.

He told me that he uses a Old Smart 16Kb sim card and there's no problem using it. He can call and send text.

I want to confirm this with other people cause I can't find any simcard that is old, active and less than 128Kb.

And please let me know how it goes ok. That would means alot for the other people who is suffering out there waiting that this cellphone will going to be unlock.

This may be the lase hope for me and for the other people who is dying and waiting for this phone to be use.

Thank you.
