The honest decision guide — eSIM vs Pocket WiFi with real cost breakdowns for 3 scenarios, where to rent for the best price, and who should (and shouldn't) bother.
In 2026, a Taiwan eSIM costs as little as THB 199 for 3 days or ~THB 500 for 7 days — significantly cheaper than Pocket WiFi for 1–2 travelers. Pocket WiFi still makes clear financial sense for groups of 3+, families, business teams and multi-device travelers. For everyone else, eSIM has largely taken over.
This page will help you answer two questions clearly: "Should I actually rent a Pocket WiFi?" and if yes, "Where do I rent it?"
Check the lists below — if you match the left column, Pocket WiFi saves money. If you match the right, eSIM is cheaper and more convenient.
A Pocket WiFi (also called a Mobile WiFi Router or MiFi) is a palm-sized device that connects to Taiwan's 4G/5G network (via Chunghwa Telecom, FarEasTone or TWM) and re-broadcasts that connection as a standard Wi-Fi hotspot that all your group's devices can join simultaneously.
The key difference from an eSIM: an eSIM works inside each individual phone (one phone, one eSIM), while a Pocket WiFi is a shared hotspot for the whole group — one device serves 5–10 gadgets at once.
It requires its own daily charging — most units last 6–10 hours per charge — and must be returned to the rental company at the end of your trip.
Pocket WiFi was the default choice for Taiwan travel 4–5 years ago. The market has shifted significantly since 2022:
Prices are approximate estimates as of early 2026 and may vary based on timing and promotions.
Bottom line: For groups of 3 or more, Pocket WiFi is a clear money-saver. For solo travelers or couples, the price gap is small enough that the added convenience of eSIM — no device to carry, no daily charging — makes it the better choice in almost every case.
