Hi NickP -
Thank you for posting all of your experiences, to date. This is extremely helpful.
Q: Do you know if you can use the emobile prepaid service with your "Huawei T-Mobile Sonic Hotspot (the E587)" device you bought? Specifically, the EM-チャージ (

Or have you tried using any SIM card from a Japanese provider? It seems like it should be that simple... just plug in the SIM and go. If you have any experiences or opinions, I'd love to hear about them.
Thanks,
Michael
