亞洲 eSIM（12 個地區）無限流量

Travelling across Asia 12 areas can mean several flights, border crossings and arrivals in unfamiliar cities. On a trip from Japan and South Korea to Thailand, Singapore or Vietnam, mobile data helps with maps, hotel check-ins, booking changes, translation and messages. This data-only eSIM lets you use one regional plan in the destinations included in this specific product, instead of arranging a new travel SIM at every stop.

Where this plan works

The supported destinations listed for this plan are Cambodia, China mainland, Hong Kong (China), Indonesia, Japan, Macao (China), Malaysia, Singapore, South Korea, Taiwan (China), Thailand, Vietnam. Check every stop against this list before purchase: a nearby country is not automatically included just because it belongs to the same wider region.

Prepare once for a multi-country trip

After purchase, follow the installation instructions provided with your order. On a compatible device, use the one-tap installation link if offered, or scan the QR code from a second screen; keep an internet connection available while installing. You can install before departure and select the eSIM for mobile data when you are ready to use it. Keep your main SIM active if you need your usual number, and check its roaming settings to avoid unintended charges.

Choose data for your itinerary

Choose the Unlimited plan duration that covers your full trip, including arrival and departure. Choose by trip length and likely use of navigation, messaging, uploads and video; a longer journey through several countries usually needs more headroom than a short city break. You can top up this Unlimited eSIM by adding extra days of validity, not GB. Hotspot, video calls and automatic backups can use the allowance quickly.

Coverage and everyday use

The connection uses the partner networks listed in the Technical Specs for supported destinations. Signal and available speeds depend on the local network, device and location; expect more variation on mountain roads, islands and sparsely populated areas than in major cities. Save essential maps and bookings offline for travel days. This is a data-only eSIM: it does not provide a new telephone number, standard voice calls or SMS. Choose the Unlimited plan duration that covers your full trip, including arrival and departure.
