Took the whole family to Japan — prepared SIMs for everyone. Swap the card on arrival and you're online. No more fighting over pocket Wi‑Fi.

First time setting up a SIM myself — much easier than expected. Support explained clearly and replied fast; online soon after inserting the card.

Needed data for a Japan business trip — email and meetings stayed smooth with no dropouts.

Hokkaido trip (Otaru, Sapporo, Hakodate) on unlimited. Swapped the card on the plane; auto-connected on arrival. Solid signal, no dropouts — worth it.

Inserted the card at Narita and stayed online all the way to Kawaguchiko.
