So far, so good!

Worked well and saved the hassle of upon arrival.

Fantastic

It is a great Sim for overseas

The Sim card worked as soon as the plane landed, no fuss, no hassle. Great coverage thru Japan. I now have another card for Europe/UK which also worked in UK straight away, still need to test it further abroad, but it's very handy having instant access upon arrival.
