Called 預付卡, yù fù kǎ, prepaid SIM cards are easily accessible in Taiwan for a relatively low startup cost. SIM cards can be purchased in city shops, at the airport, or in advance online with a simple pickup at the airport. Getting a data plan is easy, but make sure to check all the available plans before choosing.
When applying for a prepaid SIM card, remember to bring two forms of ID. A passport and secondary form of ID such as a national ID card (i.e. Singaporean NRID, Malaysian MyKad, etc.) or other state-issued form of ID such as a driver's license are recommended.
The airport SIM card desk closes at 8PM, so visitors arriving after 8PM are recommended to first reserve a SIM online, then pickup with our partner at Taoyuan Airport, open until 1AM.
SIM cards are available for online reservation from Taiwan Mobile 台灣大哥大 for 5, 7, or 10 days including unlimited 4G LTE data (with no throttling or speed reduction) and some credit for calling and texting. SIM cards from Chunghwa Telecom 中華電信 are also available for online reservation.
Using an unlimited data SIM is safer and more secure than connecting to public WiFi. When connecting to WiFi that you are not in charge of, there is the potential for other users on that WiFi to snoop and possibly view your data and/or steal passwords. When connecting to WiFi, always make sure there is a password, as connections without passwords are completely insecure and may be a honeypot where the owner specifically sets up free WiFi to steal user info. As mobile service in Taiwan is inexpensive, we recommend everyone to be safe and get a dedicated SIM. The Taiwan Mobile SIM offers free tethering to other devices, as well.
For ease and convenience, consider renting a personal mobile pocket WiFi unit with unlimited 4G LTE data for up to 5 users for only NT$100 per day, with easy pickup and drop-off at Taoyuan Airport (TPE) Terminals 1 & 2, Taipei Songshan Airport (TSA), and Kaohsiung Airport (KHH).
Mobile phone and data packages are available for reservation online and pickup in the following countries outside Taiwan:
- Singapore (Downtown)
- Malaysia (KLIA or KLIA2)
- Hong Kong (Airport) WiFi or SIM
- Thailand (BKK or DMK)
- Philippines - Manila, WiFi sharing device, delivery or pickup at airport
Chunghwa (中華電信) VS. Taiwan Mobile (台灣大哥大) VS. FarEast (遠傳)
If traveling mainly in Taipei City or other larger cities, service across all three will be consistent. In general, service quality is excellent with fast internet speeds, especially in areas with less network congestion. Due to Taiwan's mountainous topography, areas outside city centers will have varying levels of service. For travelers visiting to mountainous areas, Chunghwa is the preferred network.
FarEast and Taiwan Mobile are generally cheaper options and may offer more promotions, especially for those looking for post-paid contracts. Chunghwa has the best level of service, however, is more expensive. Within the city, the differences between the providers is minimal, and FarEast or Taiwan Mobile may provide better or worse connectivity to overseas Internet services since both are separated from Chunghwa's HiNet network.
At the moment, 5G services are offered by the major carriers, however only for those with post-paid contracts at different fare tariffs. 5G services are not available for prepaid.
How to choose a SIM card:
If your party will be traveling outside Taipei or other city areas, consider a Chunghwa SIM card. Since shops are harder to find in comparison to the other providers, consider reserving online for pickup at the airport. The price is higher than the other two, but service will be more reliable in the mountains.
If your party will mainly be in the city or visiting popular spots, consider a Taiwan Mobile or FarEast SIM card. Service is more affordable and shops are more available, and tethering WiFi is allowed with cheaper data packages. Both SIM cards are also available for pickup at the airport (TW Mobile, FarEast).
Another way to determine the best network is to match the network specifications to the mobile phone being used. Generally speaking, the newly-utilised LTE radio bands such as Band 7 (2600MHZ) are limited to newer handsets, therefore congestion on those bands is less than others. Lower frequencies can penetrate walls better, and higher frequencies can handle more data. If a handset can access more frequencies, it has the potential to create a stronger connection.
Taiwan's LTE providers operate by using the FDD-LTE world standard and is not compatible with China TDD-LTE. TDD-LTE phones will have issues using LTE in Taiwan as only Far-East supports TD-LTE on one frequency, and may be downgraded to 3G unless the handset also supports FDD-LTE. LTE network evolution categories in Taiwan are Category 6, except Chunghwa which is Category 11. Taiwan Mobile and FarEast offer VoLTE (using LTE for audio calls) service as a premium. 3G data services (including W-CDMA and HSPA+) were terminated at the end of year 2018 in a government effort to increase available frequencies for future development, so only LTE-focused services will be available and handsets which do not support 4G LTE standards will not be operational.
The following bands and frequencies are supported by each provider:

Chunghwa's Data+WiFi packages also offer connections at 50,000 APs (access point) all over Taiwan. However, for online security, be careful about connecting to WiFi hotspots you are not in control of. With unlimited data, the WiFi component most likely will not be utilised by travellers, and must be activated first by dialling 5397.
Chunghwa's customer service can be reached by calling 928. To change language, call 928, choose 4, then choose 1 for Chinese (華語), 2 for English, 3 for Japanese (日本語), 4 for Thai (ภาษาไทย), 5 for Vietnamese (Tiếng Việt), and 6 for Indonesian (Bahasa Indonesia).
