Data Sim Card /International SIM Card

[limlisa]

Last time I went to IT show , I remember got booth selling internaional SIM card which can be used in Japan as data and calling. Did anyone buy one and try before? Is the coverage for this type of card good?

If not, can anyone recommend which data sim card has better coverage and will have strong signal in most of Japan including mountain area.

These few are commonly used:

b-mobile VISITOR SIM | b-mobile wireless internet

Prepaid SIM for JAPAN | NTT Communications

All can delivered to the Airport or Hotel.

There are some that can be purchased on the spot at the airports or shops too.

In terms of signal coverage, you can see from here:
NTTƒhƒRƒ‚ -ƒGƒŠƒAƒ}ƒbƒv-

Most uses Docomo network, so the above will give you an rough idea how's the coverage at your area of interest.
