What makes eSIM different
An eSIM is a digital SIM built into your phone. Instead of buying a plastic card, you download a plan in seconds — and you're connected. That's it.
All YH eSIMs follow the GSMA SGP.22 RSP standard — the global benchmark for consumer eSIM profiles and carrier interoperability.
Where available, plans connect to 5G NR or LTE-A networks. Automatic fallback to 3G ensures coverage even in rural zones.
Every eSIM profile is encrypted end-to-end. Your identity and data are protected from the moment of download to activation.
190+ countries, one account
Our carrier partnerships span every major region. Whether you're landing in Tokyo, Cape Town, or Buenos Aires, a YH plan gets you online instantly.
