Thirty days in Taiwan usually brings in home or workplace internet, so mobile data becomes a supplement for getting around and for when Wi-Fi fails. The real question is how many hours a day you have Wi-Fi.
Quick answer
| Level of use | Roughly per day | Total for 30 days |
|---|---|---|
| Light: maps, chat, email | 0.4GB | 14GB |
| Normal: social, photos, short video | 0.9GB | 31GB |
| Heavy: streaming, video calls, hotspot | 1.9GB | 65GB |
Daily use times the days, plus 15 percent for app updates and photo backup. An estimate, not a measurement of your phone.
People who spend thirty days in Taiwan usually have reasons unlike a five-to-ten-day tourist: remote work from Taipei or Taichung, a short Chinese course, visiting family or friends, or simply living slowly in one city. The routine is steadier, with a monthly rental, a regular cafe and regular routes.
With a steady routine, mobile data stops being your main internet and becomes a backup: for commutes, when lodging Wi-Fi fails or when meeting people out. The 31 GB in the table assumes you use the phone as your main connection all month, which does not match most long-stay travellers.
The table puts thirty days at about 14 GB light, 31 GB normal and 65 GB heavy. Our catalogue has multi-country plans valid 30 days in several sizes from 3 GB to 20 GB, plus a 20 GB multi-country plan valid 90 days, but no Taiwan-only plan; 20 GB is the largest.
If lodging or coworking Wi-Fi handles the main work and the phone is a backup and for maps, 20 GB is often enough. If you regularly take video meetings over a phone hotspot, 20 GB can disappear quickly, so test the lodging Wi-Fi from the first day.
It depends on what you need. If you want a local phone number, local SMS or number-linked services, a local SIM fits better. If you just want supplementary mobile data set up in advance, a data eSIM is convenient.
If you will stay in Taiwan beyond two months or reuse it within the validity, one pack cuts repeated renewals, but check that a single data allowance is enough for that period and compare the totals yourself.

Prices are for the whole 30-day trip: a daily plan is its day price times 30. Only plans that last the trip and clear the light-use estimate.
