What matters here
Drimsim charges data by use instead of selling fixed plans, with prices in euros, while Holafly only sells unlimited plans for Japan. That difference drives most of the verdict below.
On networks, Drimsim publishes no partner network and Holafly KDDI and SoftBank. On hotspot, Drimsim does not state its policy and Holafly allows sharing.
The per-profile verdict is computed with the same score as the rest of the site, using each profile’s trip length and data need: that is why one provider can win for a family and lose for a solo traveler.
Prices move often. The table shows the plan each provider sells for the need of this page, at the price published on the date shown at the top.
If you carry a second phone or a tablet, look at the hotspot column: sharing one plan can cost less than buying two.
