# Taiwan SIM card, your US carrier or an eSIM? What a week in Taiwan costs each way

AT&T and Verizon postpaid passes cost $12 a day in Taiwan: $84 for a week on one phone (our arithmetic, checked on October 29, 2026). Our Taiwan plan is data only, sold at a USD price: 5GB for 30 days is $9.99. Its days begin at your first connection in Taiwan.

This site is not affiliated with any carrier named on this page; we sell eSIMs. [How we compare](https://esimworld.us/how-we-compare/)

You may not need an eSIM. Data in Taiwan already comes with T-Mobile Experience Beyond and More, AT&T Elite 2.0, Google Fi Unlimited Premium and US Mobile Unlimited Premium. Xfinity Mobile Plus and Select, Spectrum Unlimited Plus and three Total Wireless plans include it too.

Stay within those allowances and the trip adds no data charge, on the number you already have; each one is in the table below. Verizon Unlimited Ultimate covers 210+ countries and destinations but prints no list, so ask Verizon about Taiwan.

Two bill traps. With no pass, AT&T and Verizon both bill data at $2.05 per MB in Taiwan ([AT&T rates](https://www.att.com/international/pay-per-use-rates/), [Verizon rates](https://www.verizon.com/support/international-services-pricing/)). At that rate, 100 MB comes to $205 (our arithmetic).

On Verizon, background app refresh or email sync can open a $12 TravelPass day, and so can a call or a text ([Verizon TravelPass FAQs](https://www.verizon.com/support/travelpass-faqs/)).

## A week or two in Taiwan: pass or eSIM

Two weeks in Taiwan on one phone cost $168 on Verizon TravelPass and $100 on its Monthly Plan (our arithmetic, checked on October 29, 2026). AT&T's Day Pass comes to $120 to $168, and our 10GB plan for 30 days is $16.99, data only.

We set the options side by side on October 29, 2026: a carrier pass, data your plan already includes, and a travel eSIM. We judged each one on its price for 7 and 14 days, the data it gives, and whether calls stay on your number.

We checked 144 prices for 5GB over 30 days from 11 travel-eSIM sellers, from a US IP that day. Their middle half ran from $10.80 to $16.80; for 10GB, 155 prices had a middle half of $16.00 to $25.00.

Taiwan is not in that snapshot, so we hold no Taiwan price range: the baskets cover 29 other destinations. Read them as scale, not as Taiwan prices. No seller is named or ranked; [our methodology](https://esimworld.us/how-we-compare/) explains the baskets.

| Option for one phone | What you get in Taiwan | 7 days | 14 days |
|---|---|---|---|
| AT&T International Day Pass, postpaid | your plan's own data, talk and text | $84 | $120 to $168 |
| Verizon TravelPass, postpaid | 5 GB at high speed each 24-hour session, then 3G | $84 | $168 |
| Verizon International Monthly Plan | 20GB at high speed, then 3G; 250 minutes | $100 | $100 |
| T-Mobile Essentials with an International Pass | 10-day Pass with 15GB; 30-day Pass with 30GB | $50 | $75 |
| T-Mobile Beyond, AT&T Elite 2.0, Fi Unlimited Premium, US Mobile Unlimited Premium | the plan's own allowance abroad | $0 extra | $0 extra |
| Our Taiwan plan, data only | 5GB, valid 30 days | $9.99 | $9.99 |
| Our Taiwan plan, data only | 10GB, valid 30 days | $16.99 | $16.99 |

The AT&T spread is a billing question. AT&T's cruise page says you pay for at most 10 days in one billing cycle (checked on October 29, 2026, [AT&T](https://www.att.com/wireless/what-is-cellular-at-sea/)). So 14 days inside one cycle come to $120, and a trip split across two cycles can reach $168 (our arithmetic).

Verizon's Monthly Plan is $100 per line for 20GB at high speed, then 3G, plus 250 minutes (checked on October 29, 2026, [Verizon Monthly Plan](https://www.verizon.com/plans/international/international-travel/monthly-plan/)). On a 14-day trip it is $68 under 14 TravelPass days (our arithmetic).

T-Mobile Essentials carries no data abroad on its own. A 7-day trip then needs the 10-day Pass and a 14-day trip the 30-day Pass (checked on October 29, 2026, [T-Mobile Passes](https://www.t-mobile.com/cell-phone-plans/international-roaming-plans/unlimited-calling-data-pass)).

The included-data row is where an eSIM loses: inside that allowance, Taiwan costs $0 extra. Google Fi's footnote adds: "Data counts towards your monthly high-speed data usage." ([Google Fi](https://fi.google.com/about/international-rates))

Size the plan by your own use at home. On a week of maps and messaging in Taipei or Kaohsiung, our 5GB plan gives about 0.71GB a day. The 10GB plan gives about 1.43GB a day, and over 14 days the 5GB plan about 0.36GB (our arithmetic).

A pass keeps calls and texts on your US number. Ours is a data-only plan, and the plan doesn't state a hotspot rule — check the plan page. [Roaming or eSIM](https://esimworld.us/roaming-or-esim/) puts your own dates through the same sums.

## A Taiwan SIM card or a travel eSIM?

On a US-bought iPhone 14 or later, a Taiwan SIM card is not an option. Apple says those models "purchased in the United States can only be activated with an eSIM" (checked on October 29, 2026, [Apple](https://support.apple.com/en-us/109357)).

A local SIM card for visitors stays an option on phones with a tray. We have no checked prices or terms for Taiwanese SIM cards, so we print none. We sell no physical SIMs; [Do iPhones have SIM cards?](https://esimworld.us/help/do-iphones-have-sim-cards/) shows which iPhone models still take one.

With two lines on, Apple notes: "You might still incur roaming fees from your home eSIM" ([Apple](https://support.apple.com/en-us/118227)). Turn data roaming off on the US line ([steps](https://esimworld.us/help/data-roaming/#turn-on-off)); [keep your US number](https://esimworld.us/help/keep-your-us-number/) covers texts and 2FA codes. A call or a text on that line can still open a $12 AT&T or Verizon day.

[How to install an eSIM](https://esimworld.us/how-to-install-esim/) walks through the install on Wi-Fi at home. The U.S. Department of State rates Taiwan Level 1: "Exercise Normal Precautions" (updated November 24, 2025, [travel.state.gov](https://travel.state.gov/content/tsg_aem/us/en/home/international-travel/travel-advisories/destination.twn.html)).

## What our Taiwan plan covers

Our Taiwan plan runs on one network, Taiwan Mobile, listed as 5G (plan data as of October 29, 2026). It is data only, your US number stays on your main line, and the days count from the first connection in Taiwan.

We hold no coverage comparison of Taiwan's networks, so we make no claim about where Taiwan Mobile reaches. [How much data do I need?](https://esimworld.us/how-much-data-do-i-need/) sizes a plan for maps, messaging and video.

## Frequently asked questions

### Is a Taiwan SIM card at the airport better than an eSIM?

Not on a US iPhone 14 or later, which has no SIM tray. Apple says US-bought models from the iPhone 14 on activate only with an eSIM (checked on October 29, 2026, [Apple](https://support.apple.com/en-us/109357)). We hold no checked counter prices; on an older phone with a tray, weigh the counter's offer against the carrier table above.

### Which network does a Taiwan eSIM use?

Taiwan Mobile, listed as 5G, on our Taiwan plan (plan data as of October 29, 2026). Plans from other sellers can use other networks, so check the network named on any plan before you pay.

### Does a Taiwan eSIM work on a US iPhone?

Yes, when the iPhone is unlocked and supports eSIM. Install it on Wi-Fi at home before you fly. The clock on our plan starts when it first connects in Taiwan, not at install.
