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 YeSIM in South Korea, so its radio-side options are unknown rather than evidence of poor reach; the practical checks are the plan details in the table above. The catalogue spans a large range, making data sizing the real decision and carrying the risk of buying more than a fortnight needs. YeSIM also does not say where traffic breaks out or what its fastest stated technology is, so local delay, apparent IP location and any 5G ceiling remain unconfirmed. It has published nothing about top-up, worth checking before purchase if the data runs out.
