These Taiwan plans are data-only, with no Taiwanese phone number. Keep your home SIM on for bank and app SMS codes.
Why Taiwan is different
Paper arrival cards are gone. Since 1 October 2025 the arrival card is online only. It’s free, it’s filed on the National Immigration Agency’s own site, and the NIA warns about look-alike sites that charge for it (see entry).
Networks differ by provider. Saily lists all three big operators: Chunghwa Telecom, Taiwan Mobile and Far EasTone. Nomad lists Chunghwa and Taiwan Mobile, Ubigi lists FET (Far EasTone) and Taiwan Mobile, and Airalo names Taiwan Mobile. Holafly, Yesim and Maya didn’t name one on the pages we read.
Yesim and Ubigi are unusually cheap here. Yesim’s 20 GB for 30 days ($19.20) costs about the same as other providers’ 10 GB, and Ubigi’s 10 GB for 30 days is $14.
Quick picks
A week or two, normal use
A 10 GB / 30-day fixed plan. Ubigi listed $14, Yesim $14.40 and Nomad $16.
Heavy use or tethering
A week of unlimited data costs $22 from Ubigi or $22.80 from Yesim. Airalo ($27.00) and Holafly ($27.90) cost more. Maya’s global plan is $19.99.
Coverage across operators
Saily is the only provider here that lists Chunghwa, Taiwan Mobile and Far EasTone, and it gives you 180 days to activate. 10 GB for 30 days costs $19.99.
A month or more
Yesim’s 30 days of unlimited data costs $46.80, the lowest here, ahead of Ubigi ($49) and Maya ($49.99). For fixed data, Yesim’s 30 GB is $24.
Step 1: Size your plan for Taiwan
Maps, ride-hailing, transit apps and messaging use little data. Uploading photos and videos and making video calls use much more. As a rough guide, maps and messaging use hundreds of megabytes a day, while video and video calls can use several gigabytes. These are general estimates, not measurements.
Under a week, maps, messages and transport apps
3–5 GB fixed plan
1–2 weeks, photos, social apps and video
10–20 GB fixed, or unlimited
Remote work, video calls, tethering a laptop
Unlimited, after checking its fair-use and hotspot rules
Step 2: Compare published prices
Unlimited plans by trip length
| Days | Airalo | Nomad | Holafly | Ubigi | Yesim |
|---|---|---|---|---|---|
| 3 days | $12.50 | $12 (lowest listed) | $13.50 | — | — |
| 5 days | $19.00 | $18 (lowest listed) | $20.90 | — | — |
| 7 days | $27.00 | $25 | $27.90 | $22 (lowest listed) | $22.80 |

| 30 days | $69.00 | — | $73.90 | $49 | $46.80 (lowest listed) |
Lowest listed price in the row — means no plan of that length was listed. Holafly ($5.90) and Yesim ($6.00) also sell a single day. Maya sells one global unlimited plan at the same price for every country: $9.99 for 3 days, $19.99 for 7, $27.99 for 14 and $49.99 for 30 (see Maya). Official pages, checked 4 November 2026.

Lowest listed price in the row Validity differs, so compare the small print as well as the price. Where a provider sells the same data amount for several lengths, we show the longest. Airalo also lists shorter versions (for example 10 GB for 7 days at $17.50). Ubigi also lists 10 GB for 7 days ($12), 25 GB for 30 days ($28) and 60 GB over 12 months ($59). Yesim also lists 30 GB for $24.00. Official pages, checked 4 November 2026.
Step 3: Check the fine print
- Networks. Saily: Chunghwa Telecom, Taiwan Mobile and Far EasTone. Nomad: Chunghwa and Taiwan Mobile. Ubigi: FET and Taiwan Mobile. Airalo: Taiwan Mobile. Holafly, Yesim and Maya didn’t name one.
- Unlimited isn’t always unlimited. Ubigi says data sharing is allowed but a fair-use policy may apply. Holafly’s plans are unlimited by the day. Where it states a hotspot rule (its Canada and Italy pages), sharing is limited to 1 GB a day, so check the plan page if you plan to tether. Airalo’s Taiwan page didn’t state a fair-use limit.
- Hotspot. Saily’s Taiwan page says all plans allow hotspot. Yesim says hotspot depends on the operator.
- Activation windows. Nomad starts a plan automatically 60 days after purchase if you haven’t used it. Yesim and Saily give 180 days. Ubigi’s plan starts when you arrive.
- No Taiwanese number. These plans are data-only. Saily sells an optional US phone number.

Among the higher prices here: 10 GB for 30 days is $19.00, against $14 at Ubigi. The Taiwan page doesn’t state a fair-use limit for unlimited plans.

What stands out
The only provider here that lists all three main operators. Its Taiwan page says every plan allows hotspot, and you get 180 days to activate.
What to watch
Fixed plans cost more than Ubigi’s or Yesim’s, and nothing above 20 GB. We couldn’t read its unlimited price for each trip length.
Ubigi
- Taiwan from
- $31 GB / 7 days
- 10 GB / 30 days
- $14
- Unlimited
- $227 days; $39 for 15; $49 for 30

What to watch
It doesn’t name a network, hotspot depends on the operator, and unlimited only comes in 1, 7, 15 or 30 days.
Maya
- 3 days
- $9.99unlimited data
- 7 days
- $19.99unlimited data
- 30 days
- $49.99unlimited data
What stands out
The lowest price we found for 3 or 7 days of unlimited data, though Ubigi and Yesim are close for a week. It’s one global plan, so the same eSIM keeps working if Taiwan is one stop of several. Maya’s page says "No caps, no throttling."
What to watch
It renews automatically while Travel Mode is on, so turn it off when you get home. The page we read doesn’t name the local networks or spell out a fair-use policy, and we haven’t tested the no-throttling claim.
Will your phone work?
- eSIM-capable and unlocked. Apple lists iPhone XS, XS Max, XR or later. Settings → General → About should say "No SIM restrictions" next to Carrier Lock (full checklist).
- Bought in mainland China? Apple says that in China mainland only the iPhone 18 Pro, 18 Pro Max, iPhone Duo, iPhone 17e and iPhone Air support eSIM. Many older mainland models use two physical SIM cards instead, so check for Add eSIM in your settings before you buy a plan.
- Bought in Hong Kong or Macau? Apple notes that certain iPhone models sold there have two nano-SIM slots. Check for Add eSIM in your settings first.
- Install before you fly. Install the eSIM at home on Wi-Fi and leave the line switched off until you land (install guide).
Entry: the online arrival card
Taiwan’s National Immigration Agency (NIA) moved the arrival card fully online on 1 October 2025. Every foreign visitor files a Taiwan Arrival Card (TWAC) at twac.immigration.gov.tw, free, within the 7 days before arrival. One person can file for a group of up to 16.
Use the official arrival-card site
The NIA has warned about unofficial websites that look like the arrival-card site and charge a fee. Its notice names several, including ivisa.com. The official TWAC site is free, so if a site asks you to pay, close it.
Visa-free entry. Taiwan’s Bureau of Consular Affairs lists visa-exempt entry for many passports. For example, citizens of the USA, the UK (British citizens), Canada and Australia can stay up to 90 days; Canadian and UK nationals may apply to extend to 180. You need a passport valid for your stay and an onward or return ticket. Check the BOCA list for your passport.
Our take
For most trips, Ubigi’s 10 GB for 30 days at $14 or Yesim’s at $14.40 are the lowest-cost plans that cover normal use. For unlimited, Ubigi’s week costs $22. If you want the widest network list, Saily is the only provider here that names all three operators. And file your free TWAC before you fly.
Affiliate links. Prices are set by the provider and confirmed at checkout.
Before you fly

Buy and install at home
Install on Wi-Fi before departure and keep the line off until you land. With Nomad, don’t buy more than 60 days ahead.
