Nokia e63 in Japan

I've recently bought a Nokia E63-2 and when I put the simcard I normally use from Softbank it does not work, although I manage to connect to internet only.

Is there someone who can help me how to go about it.
Regards

I have an E75-1 which I bought in Kuwait, and it works everywhere in the world except here. That is, it *would* work (I can roam from home on it), but SoftBank refuses to sell or rent a SIM card, as far as I can tell. My guess is that your internet connection is through your Wi-Fi, and nothing to do with the SIM card--I have no doubt that the cell providers here are savvy enough to query your IMEI and cut you off if it's not actually a phone they sold you.
Just t be clear--I can roam with T-Mobile from home with this phone in Japan. That means that this phone would work here, except that in Japan, working with others is not important. Forcing you to buy ugly, barely functional handsets is important.

If obtaining a SIM is your only problem then be aware that Softbank has rental SIM cards. They are only available at the Narita Airport, Kansai International Airport, Nagoya / Central Japan Intl Airport, Fukuoka Airport, and New Chitose Airport branches.

Hmm, but your phone will work here...
