The "sumaho" voice SIMs now have an additional option for data: a 1 GB plan for ¥1,980. Also, the 200 kbps data plan was replaced with a less expensive 150 kbps data plan. There will be essentially no difference in the old and new low-speed option from a user perspective. Both will be similarly slow and suited only for short messages and light maps usage.
These are FOMA 3G SIMs. They are not compatible with Docomo Xi handsets. A Nano SIM is also available, but only direct from JCI. Amazon and Yodobashi don't carry nano SIMs. Billing is postpaid, monthly recurring.
