About YeSIM
Swiss-run Genesis Group AG operates YeSIM, which sells fixed country and regional data bundles alongside a pay-as-you-go option, Pay & Fly, whose unused balance carries over to later trips. Daily unlimited passes and a multi-country global package are also listed. The eSIM is data-only, with calls and messages handled through apps such as WhatsApp, and hotspot sharing is enabled by default.

No operator names are published for Japan, so the radio side of YeSIM’s service is unknown rather than bad; the table above is where to check the allowances and validity on offer. Its large range of plans makes sizing the real decision, with the risk of buying more data than a fortnight actually needs. YeSIM also does not say whether an exhausted plan can be topped up, so confirm that before buying if extending service matters.
