Your best bet is going to be cutting down a micro SIM: http://www.miniinthebox.com/aluminiu...i_p444727.html

Unfortunately, as far as I know, no one is selling these.

Do you have a link? The only reference to a nano-SIM I can find on their website is for monthly subscriptions including voice service (and thus requiring ID) from back in November:

We just travelled to Japan for 10 days and hired 3 1gb data cards for our iphone 4s's. We got two from bmobile and one from econnect. All worked fine for both but I just wanted to say that even though econnect was slightly dearer 4600yen vs 3800 yen (or something like that) their communications were much better than bmobile. Econnect emails were answered promptly by people that speak good english, and I needed help with the settings whilst there (cos I couldn't find my way round the iphone!!) and they replied straight away.
Also econnect were able to deliver a sim card to our hotel within 24 hours notice when I contacted them by email.
BTW we used the skype messaging service to contact each other whilst out and about. We couldn't seem to get the skype voicecalls up and running. Have to work on that now that we are back home. Also you can't hotspot with the cards.

And I bought a micro SIM for my Droid Razr Maxx. It doesn't find a signal. I think this phone, which I now notice is not on the list of known approved phones buried deep on the bMobile site, doesn't transmit/receive on DoCoMo 3G frequencies.
Anyone want an unused SIM that is good until March 29? PM me!

Sadly I can't find the site I read this on, but apparently this is caused by the bmobile SIM having no voice capability, which is very unusual. Failure to register with the voice part of the network causes Android to show no signal no matter what.

I'm heading to Japan in 3 weeks with an iPad mini 3G.
Can anyone advise if they have had success cutting down the docomo foam micro sims from econnectjapan? The iPad mini needs a nano sim.
I'm just concerned because somebody told me the sims are the wrong size for cutting down and you just destroy them in the process...
Thanks in advance!

>> This is a known issue with most Android devices - they show no signal but if you have configured the APN settings correctly they will still get a data connection.
Same for my various iPhone's and Sony Ericsson dumb phone but they all worked fine with the B Mobile. Who cares what the signal meter says. However the phones did show the carrier name "DoCoMo". That's the proof that a connection has been made.
