APAC eSIM for multi-stop journeys
Planning a long-haul route across Asia and the Pacific? Keep one APAC eSIM installed for the destinations shown in your selected plan’s live coverage list, while avoiding a new mobile-data setup at each included stop.
One APAC eSIM currently covers twelve destinations on a single data plan — Australia, China, Hong Kong, Indonesia, Japan, South Korea, Malaysia, New Zealand, the Philippines, Singapore, Thailand and Vietnam. APAC is a practical label for a vast travel area, but its boundaries differ between providers and plans. It can suit a long-haul circuit with city stays, onward flights and island connections, provided each stop appears in the live destination list for the exact package you choose. Review that list rather than assuming that India, Taiwan or any other market is included. Mobile service can also change between dense urban centres, rural roads, mountain areas and smaller islands, so download essential tickets and directions before remote legs.
Refund policy
We always refund the full amount you paid when you request it, whether your eSIM is unused, partly used or fully used. There is no time limit for requesting a refund.
No first-use deadline
Validity does not start until your eSIM connects to a supported network at your destination. There is no deadline for first use. You can buy now and keep your plan for a future trip.

How eSIM works in Asia Pacific
Choose the data amount and validity for the whole APAC itinerary, then verify all twelve destinations in the live list. Install the eSIM on reliable Wi-Fi before the long-haul flight; there is no separate manual activation step. Keep the line off in transit. Its first successful connection to a supported network at an included destination activates the package and begins the validity selected at checkout. Choose Horizon for mobile data, enable roaming on that line and leave the profile installed for later flights or ferries. Save tickets and maps offline before remote island or rural legs.

Size it to your trip
Pick the profile closest to your trip. The estimate assumes normal use — maps, messaging, photos, a short call home.
As a rule of thumb, a 3–4 day city break runs on about 1–3 GB, a one-week trip on 3–5 GB, a two-week multi-country tour on 8–12 GB, and working on the road takes about 1 GB a day, so 15 GB or more for two weeks.
Recommended size
3GB3–4 days
≈0.4 GB a day
- Maps every day
- Messaging and photos
- A short call home most days
In total, a 5 GB data allowance covers roughly 1,700 shared photos, 83 hours of social media and browsing, 15 hours of video calls, 63 hours of music streaming, or about 1000 hours of maps and navigation. Messaging apps barely use data.
Staying three weeks to a month, or using data heavily every day? That is the trip the 20 GB plan is priced for.

Why Horizon
Built for complex APAC itineraries
A regional eSIM reduces the number of mobile-data profiles to manage on a journey with several flights or border crossings. You can keep your home SIM available for calls and texts if your phone supports two active lines, but your home operator may charge for that use. Choose the Horizon line for data and keep data disabled on the home line. Hotspot sharing is free on every Horizon plan.

Frequently asked questions
Which destinations are included in an APAC eSIM?
Horizon's APAC eSIM currently covers twelve destinations: Australia, China, Hong Kong, Indonesia, Japan, South Korea, Malaysia, New Zealand, the Philippines, Singapore, Thailand and Vietnam. Boundaries differ between products, so the live destination list for the package on this page stays the authority — confirm each planned stop there before purchase.
Can I keep the same eSIM when crossing borders?
Yes. Keep the same eSIM installed while travelling between the twelve included destinations. After each border or flight, leave Horizon selected for mobile data and allow the phone time to register on a supported local network; only a stop outside the listed coverage needs another plan.
When should I install and activate the APAC eSIM?
Complete the APAC eSIM setup on Wi-Fi before the long-haul flight; there is no separate manual activation step. Keep the APAC line off in transit. On reaching any of the twelve included destinations, select Horizon for mobile data and enable roaming for that line. Its first successful connection to a supported local network activates the package and begins the validity period selected at checkout; leave the profile installed for the next flight or ferry.
Does the APAC eSIM include a phone number?
No. The regional eSIM is a data-only line with no phone number. On a compatible dual-line phone, your usual SIM may remain active for calls and texts, subject to charges from your home operator.
Can I share APAC eSIM data through a hotspot?
Hotspot sharing is free on every Horizon plan. Enable Personal Hotspot on a compatible phone and keep Horizon selected for mobile data. Connected devices use the same plan data.
What should I expect on rural routes and islands?
Availability can vary with terrain, distance from settlements and local partner networks. Save maps, booking details and essential contacts before remote road, mountain or island segments, and reconnect when a local signal is available.
Will Horizon slow down my data?
No. Horizon plans have no throttling. There is no daily limit that slows you down, so you can use your whole plan in one day if you need to. Your speed depends on the local network, your signal and how busy the network is. When your data allowance is used up, the plan stops rather than slowing down.
Can I get a refund if I already used some data?
Yes. We always refund the full amount you paid when you request it, whether your eSIM is unused, partly used or fully used. There is no time limit for requesting a refund.

Asia eSIM vs APAC eSIM: does it include Australia, New Zealand and China?
Two labels, one question: is your stop on the list? The current Asia Pacific list names twelve destinations, Australia, New Zealand and mainland China among them, with Hong Kong listed separately.
Guides
How much data for a multi-country Asia-Pacific trip?
A three-week route is not twenty-one similar days. Size it on the days that move — flights, intercity legs, first days in a new city — and check the calendar as carefully as the gigabytes.
