eSIM Taiwan: prepaid data on Chunghwa Telecom Taiwan and Mobile Taiwan, from Taipei to Kaohsiung
Taiwan runs on the phone: the transit card app, high-speed rail tickets, night-market food finders, scooter and bike rentals, and the group chat that decides which dumpling place to try next. Arriving at Taoyuan with only a home roaming pass means paying daily for all of it, and queueing at an airport counter is a poor start to the trip. A Taiwan eSIM is easier: buy online, install over Wi-Fi at home, and your phone connects automatically on landing while your own number stays live on your primary SIM.
Networks and coverage in Taiwan
GlobaleSIM’s eSIM Taiwan connects to two partner operators, Chunghwa Telecom Taiwan and Mobile Taiwan. Two networks on one prepaid data plan means your phone attaches to whichever is available, and you can switch manually if one is weak inside a mall or on a mountain road. Coverage is excellent in Taipei, Taichung, Tainan, Kaohsiung and Hualien and along the high-speed rail and highway corridors; in the central mountains, the gorges of Taroko and the rural east coast, signal is thinner on all networks.
Tarife, Preise und Gültigkeit
Taiwan eSIM plans start from $4 for 1GB and go up through 2GB, 3GB, 5GB, 10GB, 15GB and 20GB. Validity is 7 days for 1GB, 10 days for 2GB, 14 days for 3GB, 21 days for 5GB, and 30 days for 10GB, 15GB and 20GB. A five-day Taipei city break with maps, metro and food apps is fine on 3GB; a two-week island loop with navigation, video calls and a lot of photo uploads suits 10GB; remote workers and hotspot sharers should choose 15GB or 20GB. The clock starts only at the first connection to a supported network in Taiwan, so installing before your flight loses no days.
Anrufe und eine Telefonnummer
Data-only is enough for most visitors, since hotels, hosts and tour operators in Taiwan respond on messaging apps and your own number still rings on the primary SIM. If you need to phone restaurants for reservations, call a rental desk or receive SMS codes, add a voice-minutes bundle (+100, +200 or +300 minutes) and you receive a dedicated international phone number (US +1 or UK +44) for calls and SMS. Data-only travelers do not get calling.

Tips for mobile data in Taiwan
Taiwan has plenty of free public Wi-Fi in stations and convenience stores, but registration steps and dropouts make it a backup rather than a plan. Navigation apps handle the metro, buses and the high-speed rail well, and bike-share and scooter apps need a live connection to unlock. Night markets and small eateries are largely cash-only, so keep a map of ATMs handy; convenience stores accept cards and can top up transit cards. For a day trip to the outlying islands, expect weaker signal on the ferries. Data works only inside Taiwan; for onward travel, pick a plan for the next country.
