Travel SIM 4G — Connected the Moment You Land
No need to hunt for a SIM counter in an unfamiliar airport. TSS prepares a data SIM matched to your destination and trip length, delivered to your door before departure or handed to you at the airport.
Why book your SIM before you fly
Domestic carriers' international roaming is often expensive and capped. TSS travel SIMs run on local telecom infrastructure — more stable speeds and noticeably lower cost for trips of 3 days or more.
Wide coverage
Japan, Korea, the US, Europe, Southeast Asia and 80+ other countries, on local 4G/5G networks.
Instant activation
Pre-activated or QR-activated the moment you land — no paperwork, no waiting.
Multi-device support
Wi-Fi hotspot plans available for groups/families sharing one SIM or device.
Bilingual support
Vietnamese-speaking support over Zalo throughout your trip if your SIM has any connection issues.
