A Japan–Thailand holiday and a trip that continues to Australia need different eSIM comparisons. The word “Asia” does not guarantee Australia or New Zealand is included, and a regional package is not automatically cheaper than two country purchases.
Prices checked 25 September 2026. Horizon includes instant support and free hotspot sharing. Nomad currently costs less than Horizon at both matched APAC allowances below; Airalo also costs less at 10 GB, but its Asia package excludes Australia and New Zealand. Start with the country list, then compare the price for the data and days you need.
5 GB and 10 GB for 30 days
Each fixed offer below provides a total allowance for 30 days. Coverage differs:
- Horizon APAC: 5 GB €13.03; 10 GB €25.87.
- Nomad APAC, selected 14-country option: 5 GB €12.20; 10 GB €18.30.
- Airalo Asia: 5 GB €13.50; 10 GB €22.50.
- Saily Asia and Oceania: 5 GB €17.49; 10 GB €31.99.
Nomad is €0.83 cheaper at 5 GB and €7.57 cheaper at 10 GB than Horizon. Airalo's 10 GB price is €3.37 lower than Horizon's. These are price differences, not evidence that reception, speeds or support are identical. Horizon instant support can help check whether its country list fits your route before purchase.
Australia, New Zealand and the stops between them
Horizon's checked APAC list is Australia, China, Hong Kong, Indonesia, Japan, Malaysia, New Zealand, Philippines, Singapore, South Korea, Thailand and Vietnam. The allowance is shared across these named destinations; a border crossing does not replenish it or restart its validity.
The selected Nomad APAC option includes those same destinations plus Macao and Taiwan. Saily's Asia and Oceania list includes the Horizon destinations plus Bangladesh, Cambodia, India, Kazakhstan, Laos, Macau, Pakistan, Sri Lanka, Taiwan and Uzbekistan.
Airalo Asia includes Bangladesh, Cambodia, China, Hong Kong, India, Indonesia, Japan, Laos, Macao, Malaysia, Pakistan, Philippines, Singapore, South Korea, Sri Lanka, Taiwan, Thailand and Vietnam. Australia and New Zealand are absent. A lower Airalo Asia price therefore does not cover the same Australia–Japan–Thailand itinerary as the APAC offers above.
Holafly Asia also excludes Australia and New Zealand. Its checked list is Cambodia, China, Hong Kong, Indonesia, Japan, Laos, Macau, Malaysia, Pakistan, Philippines, Singapore, South Korea, Sri Lanka, Taiwan, Thailand and Vietnam. For an Australia or New Zealand leg, check a different Holafly product or a separate purchase and include that cost.
For the naming and territory checklist, use our Asia versus APAC guide. The Australia–New Zealand–Japan itinerary guide explains how to check several stops without assuming a whole continent is covered.
Japan plus Thailand: two country purchases can cost less
Suppose you need 5 GB in Japan and 5 GB in Thailand, with each country visit fitting inside its own 30-day validity:
- Horizon Japan 5 GB / 30 days: €12.46.
- Horizon Thailand 5 GB / 30 days: €3.53.
- Two-purchase total: €15.99.
That costs €9.88 less than Horizon APAC 10 GB and €2.31 less than the quoted Nomad APAC 10 GB. But it buys two separate 5 GB allowances. Unused Japanese data cannot become Thai data, and the purchases have separate activation and expiry rules. A trip using 8 GB in Japan and 2 GB in Thailand needs a different allocation or a shared regional pool.
Regional coverage becomes more useful when stops multiply or the split is uncertain. A third country purchase could change the total. Check the Japan provider comparison and Thailand provider comparison for those individual legs, then recalculate rather than assuming one regional price wins every itinerary.
A longer trip changes the validity comparison
Horizon lists 20 GB / 90 days at €51.58. Nomad's selected APAC option lists 20 GB / 45 days at €30.49, on public sale from €34.85, and 50 GB / 45 days at €44.43. Saily lists 25 GB / 60 days at €43.49.
Both competitors offer a lower purchase price in those examples, but neither quoted plan lasts 90 days. For a 40-day itinerary, the lower-priced Nomad offer may fit. For a continuous 70-day trip, the quoted Nomad and Saily options expire too early; price the next purchase or choose a suitable longer-validity option. Do not count remaining gigabytes as usable after expiry.
For light use, Horizon's 1 GB / 30 days costs €2.75. It is a smaller total allowance, not 1 GB each day. Use the APAC data-sizing guide to budget maps, uploads and sharing before choosing.
Unlimited phone data and laptop sharing
Holafly's official Asia duration table quotes 7 days of unlimited phone data at US$27.50. The quoted package allows 1 GB per day of hotspot sharing. Holafly describes possible temporary operator fair-use speed reductions. This USD seven-day offer is separate from the fixed 30-day EUR comparison; we do not convert it or use it in euro savings calculations.
Horizon allows free hotspot sharing from the purchased allowance, without a separate daily hotspot cap. Nomad supports tethering subject to device and network conditions; Airalo permits it when the device and network support it. Saily's regional technical details state no hotspot restrictions or limitations. With a fixed plan, all connected devices consume the same purchased total.
Instant support and how we checked
Horizon includes instant support for setup, mobile-data settings and connection questions. Check device compatibility, confirm the phone is unlocked and install using a stable internet connection. Contact Horizon for help matching its current plans to your stops.
