One eSIM for the Philippines and Japan, Vietnam or Thailand (2026): When a Regional Plan Beats Two Country Plans
Fizen's Asia eSIM covers the Philippines, Japan, Vietnam, Thailand and 14 more countries. Networks per country, and when one regional plan beats two country plans, with app prices checked 3 November 2026.
Quick answer: Yes: as of 3 November 2026 one Fizen Asia eSIM covers the Philippines, Japan, Vietnam, Thailand and 14 more countries, on Smart in the Philippines, NTT Docomo in Japan, Viettel in Vietnam and AIS in Thailand. On price, two country plans came out lower on every two-country pairing we checked, so the regional plan earns its place on trips with three or more stops or short hops.
Key takeaways
- Fizen's Asia plan covers 18 countries, including the Philippines, Japan, Vietnam, Thailand, Singapore, Hong Kong, South Korea and Taiwan.
- The network changes in the Philippines: Smart on the Asia plan, Globe on the Philippines country plan.
- Two country plans were lower for Philippines plus Japan or Thailand, for example US$27.38 for 20 GB against US$38.00 on the Asia plan.
- Against Airalo's Asia eSIM, a new Fizen app user saves 5% to 6% on 10 GB plans (3 November 2026).
A week of island-hopping in Palawan, then a flight to Osaka, Da Nang or Bangkok: the route is the easy part. The question that hits at the gate is whether the eSIM you installed for the Philippines will work when you land in the next country. Here is how one regional eSIM compares with a plan per country, with Fizen app prices checked on 3 November 2026.
Can one eSIM cover the Philippines, Japan, Vietnam and Thailand?
Yes. Fizen's Asia eSIM covers 18 countries: Australia, Hong Kong, India, Indonesia, Japan, Kyrgyzstan, Laos, Malaysia, New Zealand, Pakistan, the Philippines, Singapore, South Korea, Sri Lanka, Taiwan, Thailand, Uzbekistan and Vietnam. It comes in 1, 5, 10, 20 and 50 GB, and slows to 128 kbps when the data runs out instead of cutting off.
| Country | Network on Fizen's Asia plan |
|---|---|
| Philippines | Smart (5G) |
| Japan | NTT Docomo (5G) |
| Vietnam | Viettel (4G) |
| Thailand | AIS (5G) |
| Singapore, Hong Kong | StarHub (5G), 3 (5G) |
| South Korea, Taiwan | SK Telecom (5G), Chunghwa Telecom (5G) |
Networks are from Fizen's catalogue on 3 November 2026. Fizen's Philippines country plan uses Globe instead, so pick the country plan if Globe is the network you trust on your islands.
Is one Asia plan or two country plans cheaper?
| Trip, new Fizen app user | Two country plans | One Asia plan |
|---|---|---|
| Philippines + Japan, 7 days each, 10 GB each | US$15.48 + US$11.90 = US$27.38 | 20 GB, 15 days: US$38.00 |
| Philippines + Thailand, 7 days each, 10 GB each | US$15.48 + US$9.87 = US$25.35 | 20 GB, 15 days: US$38.00 |
| Philippines + Japan, 7 days each, 5 GB each | US$10.26 + US$6.99 = US$17.25 | 10 GB, 15 days: US$22.80 |
Two country plans won each pairing, and each gives you a dedicated plan per country. The US$10 welcome credit is one balance: each plan uses part of it, up to 30% of that plan, until it runs out. In every pair above the two plans together use less than the US$10. App prices can differ by a few cents; checked 3 November 2026. For Vietnam, check the eSIM tab in the app or fizen.io/esim for current Vietnam plans.
When does one regional plan beat two country plans?
- Three or more stops in two weeks, for example Manila, Hanoi and Bangkok: one install, one data pool, and no second order once your credit is used up.
- Short hops and layovers, such as a day in Singapore or Hong Kong between flights, where a separate plan would mostly go unused.
- You hate surprises at the gate: the Asia plan is already live when you land in the next country.
- Country plans win for two countries with a week or more in each, for heavier use, and for Globe in the Philippines.
Most Fizen eSIMs cannot be topped up, so size the plan for the whole route: more data means a new eSIM.
Is Fizen's Asia plan cheaper than Airalo's Asia eSIM?
On two 10 GB plans, yes. Exclusive to new Fizen app users: US$10 of eSIM credit lands in the eSIM tab the moment you join and pays for up to 30% of each plan until it is used. Airalo's Asia page says it covers 18 countries; check that every stop on your route is on its list.
| Plan | Airalo | Fizen app, new users |
|---|---|---|
| Asia, 10 GB, 7 days | US$23.00 | US$21.62 SAVE 6% |
| Asia, 10 GB, 15 days | US$24.00 | US$22.80 SAVE 5% |
App prices can differ by a few cents; checked 3 November 2026. More benefit: US$2 of eSIM credit after every order, for your next trip.
What else changes when you cross borders?
Install the eSIM on home Wi-Fi before your first flight, and leave data roaming on for that line in every country. A travel eSIM is data-only, so keep your home SIM for bank codes. If both the Philippines and Vietnam are on the route, the same app can pay local QR codes as a visitor with Fizen QR Pay: QR Ph in the Philippines, and in Vietnam only QR codes of Vietnamese account holders. Deposit USDT on Solana or BNB Chain from your Fizen wallet into QR Pay; limits are US$800 per payment and US$1,000 per week.
