Three "Southeast Asia" eSIM Plans, Three Different Country Lists

• 7 countries: Cambodia, Indonesia, Malaysia, the Philippines, Singapore, Thailand and Vietnam.
• 12 countries: Cambodia, Indonesia, Malaysia, Singapore, Thailand and Vietnam, plus China, Hong Kong, Japan, Macau, South Korea and Taiwan. The Philippines isn't included.
• 19 countries: Indonesia, Laos, Malaysia, the Philippines, Singapore, Thailand and Vietnam, plus China, Hong Kong, Japan, South Korea, Taiwan, Bangladesh, India, Pakistan, Sri Lanka, Kazakhstan, Kyrgyzstan and Uzbekistan. Cambodia isn't included.
• Singapore & Malaysia & Thailand: those 3 countries only.

Brunei, Myanmar and Timor-Leste aren't on any of these four lists. Skylano sells Brunei as its own destination on the Brunei eSIM page.

As listed on November 2, 2026:

All three Southeast Asia plans are listed on the Southeast Asia eSIM page, and the 3-country plan on the Singapore, Malaysia and Thailand eSIM page; on the Southeast Asia page, match the price to tell the 7, 12 and 19-country plans apart. The 7-country plan also comes as a daily plan: 5GB per day for $10.99 per day (daily plan), slowing to 384 Kbps after the daily 5GB. All four plans allow hotspot sharing.

• Only Singapore, Malaysia and Thailand: the 3-country plan is the smallest list that covers the trip.
• Adding Indonesia, Vietnam, Cambodia or the Philippines: the 7-country plan lists all of them.
• Combining Southeast Asia with Japan, South Korea, China, Taiwan, Hong Kong or Macau: the 12-country plan, as long as the Philippines isn't on your route.
• Adding Laos, South Asia or Central Asia, or pairing the Philippines with East Asia: the 19-country plan, as long as Cambodia isn't on your route.

One route no single plan here handles: Cambodia, the Philippines and Japan on the same trip. The 7-country plan has no Japan, the 12-country plan has no Philippines, and the 19-country plan has no Cambodia. For that trip, pair a regional plan with a single-country plan for the missing stop.

All three Southeast Asia plans are on the Southeast Asia eSIM page. For general advice on multi-stop trips, see Regional eSIM for multi-country travel and our guide to regional eSIM country lists.
