let me help to answer that. this nexus 7 only got wifi conection. no gsm and data(3g). so i believe no sim.

received mine too. thanks to bro shiro!

if convert direcly yes you are right.
but even in the US there, google even charge for delivery. but some retailer do sell at the base price.
then, postage to malaysia is not free. quite expensive. then, might have to pay for tax and finally local postage.
finally of course seller want some profit for his service.

ill say, bro shiro price is the best. i know few other seller, but their price is much more expensive. there are few selling at riddiculously cheap price, but they havent even bring in their first batch. scared scam case.

i am very happy with shirogawa service, i will definitely deal with him again. recommended seller.
