For most trips to Taiwan, a prepaid travel eSIM is cheaper than international roaming on an Australian plan, and you can install it before you leave. Coverage runs on local networks (Chunghwa Telecom, Taiwan Mobile and FarEasTone); travel eSIMs are usually data-only, so check whether you need a local phone number. Airalo’s Taiwan eSIM started from US$4.00, with unlimited plans from US$12.50 for 3 days (3GB a day, then 1 Mbps), when we checked on 30 October 2026.

Airalo prices checked on Airalo’s own site on 30 October 2026, in US dollars; providers change prices without notice, so confirm before you buy. Airalo lists Taiwan Mobile as the network for this eSIM.
Coverage and networks in Taiwan
Taiwan’s three main networks are Chunghwa Telecom, Taiwan Mobile and FarEasTone, and 4G and 5G coverage is strong across Taipei, the west-coast cities and the high-speed rail line. Airalo’s Taiwan eSIM uses Taiwan Mobile (5G listed). Mountain areas such as Taroko Gorge and Alishan can have patchier signal, so download offline maps before day trips.
How much data you need for Taiwan
- Light use (maps, messaging, a little browsing): roughly 0.5–1GB a day.
- Moderate use (social media, photo uploads, rideshare apps): about 1–2GB a day.
- Heavy use (video calls, streaming, hotspot for a laptop): 3GB a day or more — check fair-use caps and hotspot rules first.
These are general estimates, not measurements. Hotel and café wi-fi can stretch a smaller plan.
eSIM vs roaming vs local SIM
| Option | Set-up | Typical trade-off |
|---|---|---|
| Travel eSIM | Online, before you fly | Usually data-only; often cheapest for short trips |
| Australian roaming pack | Nothing to install | Keeps your number; usually more per GB |
| Local Taiwan SIM | Airport or shop, with ID | Local number; queues and registration |

Taiwan-only vs an Asia plan
If Taiwan is your only stop, a country plan is cheaper than a regional one. If you’re combining it with Japan, Hong Kong or South Korea, an Asia plan saves buying several eSIMs — check every country on your route is listed.

How to install and when to activate
Check first that your phone supports eSIM and is unlocked. Install the eSIM at home on wi-fi, then switch it on and enable data roaming for that line when you land.

We haven’t yet hand-checked Saily, Nomad or Ubigi prices for Taiwan, so they’re not in the table above.

Questions travellers ask
Does an eSIM work in Taiwan?
Yes. Travel eSIMs for Taiwan connect to local networks such as Chunghwa Telecom, Taiwan Mobile and FarEasTone, as long as your phone supports eSIM and is unlocked.
When should I activate my eSIM?
Install it at home on wi-fi a day or two before you fly and switch it on, with data roaming enabled for that line, when you land. Check whether your plan’s validity starts at installation or first connection.
Will my phone work with an eSIM?
It will if it has an eSIM chip and is carrier-unlocked. On iPhone, look for an EID under Settings > General > About; on Android, look for Add eSIM in SIM settings or dial *#06#.
Do I get a local phone number with a Taiwan eSIM?
Usually not. Most travel eSIMs are data-only, so you call and message over apps such as WhatsApp. Some providers sell plans with a number, minutes or texts; check the plan details.
Is an unlimited Taiwan eSIM really unlimited?
No. Airalo’s unlimited Taiwan plans slow to 1 Mbps after 3GB a day (checked 30 October 2026). For most trips a fixed-data plan is cheaper. Every provider’s daily cap →
