Best eSIM for Taiwan: Real Prices Compared for Taipei, Kaohsiung and Beyond

Taiwan is a country where data pays for itself fast — Taipei's night markets and metro system are far easier with Google Maps running, and once you're out at Taroko Gorge or Sun Moon Lake, you'll want a working connection well before you lose signal, not after. An eSIM means you can land at Taoyuan, scan a QR code before baggage claim, and skip the arrivals-hall SIM counter entirely.

It also means you can hop on the High Speed Rail down to Kaohsiung or out to Alishan without worrying about which local carrier has decent coverage where you're headed — the eSIM travels with you across the whole island, unlike a physical SIM you'd have to plan around picking up.

We checked live pricing across 118 providers we track for Taiwan, and the price for identical data varies a lot depending on who you buy from. We pulled every currently active Taiwan plan straight from our database — not an advertised "from" price — so you can see exactly what's cheapest for your trip.

Quick-answer picks

• Shortest trip, light use: Ubigi's regional 0.5GB/1-day bundle at $2.00 is the outright cheapest entry point we found, though it covers a wider Asia region rather than Taiwan alone — Signalinks' 1GB/1-day at $2.50 is the cheapest Taiwan-only equivalent.
• One week, moderate data: eSIMCard — 5GB for 7 days at $7.45
• A standard month of data: eSIMCard — 10GB for 30 days at $14.40
• Best for going unlimited: eSIMCard — unlimited data for 30 days at $40.55, ahead of Ubigi ($49.00) and Maya Mobile ($49.99)
• Best for long stays: Ubigi — 60GB spread across a full year (365 days) for $59.00 total

Provider-by-provider breakdown

eSIMCard — the sharpest all-round pricing

eSIMCard covers nearly every use case competitively: 5GB for 7 days at $7.45, 10GB for 30 days at $14.40, and unlimited data for a full 30 days at $40.55 — the cheapest 30-day unlimited option we found for Taiwan. Every tier is Taiwan-specific, with durations running from a single day up to 90 days, so there's rarely a gap between the length of your trip and the plan sizes on offer.

Signalinks — deep short-duration variety

Signalinks has one of the most granular catalogs we've seen for any destination — real tiers at 1, 3, 5, 7, 10, 15, and 30 days, each with five or six data sizes to choose from. Its standout is bulk value: 90GB for 30 days at $46.90, the best per-gigabyte rate of any Taiwan provider we track. If your trip length falls awkwardly between the usual 7/15/30-day tiers other providers offer, Signalinks is worth checking first.

nadanada — simple and cheap for shorter stays

nadanada runs a straightforward single-country ladder: 1GB for 7 days at $2.99, up through 10GB for 30 days at $20.99 and 100GB for 30 days at $144.99. It's not the cheapest option at every tier, but it's dependable, entirely Taiwan-specific, and easy to compare at a glance without wading through regional bundles.

Maya Mobile — the flat-rate baseline

Maya Mobile charges its usual flat rate in Taiwan — $9.99 for 3 days, $19.99 for a week, $27.99 for two weeks, $49.99 for 30 days, unlimited throughout. It's a useful baseline for comparison, but both eSIMCard and Ubigi beat its 30-day unlimited price specifically for Taiwan.

Orbit Mobile — an easy monthly starter

Orbit Mobile keeps its Taiwan lineup to five 30-day tiers, from 1GB at $3.50 up to 20GB at $24.00. Straightforward if you just want one plan for a month without comparing durations.

Ubigi — the long-stay option

Ubigi has the deepest range of durations for Taiwan, stretching out to a full year. Its standout is 60GB spread across 365 days for $59.00 total — a genuinely different use case from a short trip, built for anyone who returns to Taiwan often enough to want a SIM that's simply always live. Its short-trip pricing is solid too, with a Taiwan-only Unlimited/30-day tier at $49.00, just behind eSIMCard.

Why prices vary so much for the same country

The gap between Signalinks' bulk rate and several times that from other providers comes down to how the eSIM resale supply chain works. Most of these providers don't run their own network in Taiwan — they buy wholesale roaming capacity from Taiwanese or regional carriers and resell it with a markup, and that wholesale rate depends on which carrier they've partnered with and how much capacity they've committed to. It's also worth knowing that the same provider can price wildly differently country to country — a reminder that "cheap in one country" doesn't guarantee "cheap everywhere" from the same brand.

Pick by trip type

• Weekend in Taipei: Signalinks' 1GB/1-day or eSIMCard's 5GB/7-day plan covers night markets, the metro, and photos without overpaying.
• A week combining Taipei with Taroko Gorge or Sun Moon Lake: eSIMCard's 5GB/7-day at $7.45 gives enough headroom for offline-map downloads in the mountains.
• A full month touring the island: eSIMCard's unlimited 30-day plan at $40.55 removes any risk of running out mid-trip.
• Frequent visitor or long-term stay: Ubigi's 365-day, 60GB plan at $59.00 is purpose-built for exactly that.

Practical caveats

Most plans above are data-only, without voice minutes or SMS — fine for most travelers, since calls and texts typically run over a messaging app instead. If you need a real phone number with voice/SMS included, check the "include voice & SMS plans" toggle on the Taiwan plan list, since those plans are hidden by default.

Hotspot support varies by plan, so check the details first if you're sharing your connection with a laptop. And if you've never set up an eSIM before, our guide on checking eSIM compatibility walks through the settings-based way to confirm your phone supports one.

Install the eSIM before you fly rather than waiting until you land — every provider on this list lets you activate it in advance and it'll simply connect once your plane touches down at Taoyuan, so there's no reason to rely on airport wifi while you queue for immigration.

If this is your first time using an eSIM, our beginner's guide to how eSIMs work covers installation from the very start. For the full, current list of Taiwan eSIM plans — filterable by data amount, trip length, and provider — visit the Taiwan plan page.
