Things you need to know before buying a Taiwan eSIM

  1. Main 5G/4G frequency bands in Taiwan

Taiwan’s 5G networks operate primarily on the 3.5 GHz band (n78) and 28 GHz (n257). 4G LTE uses bands 1 (2100 MHz), 3 (1800 MHz), 7 (2600 MHz), and 8 (900 MHz). Ensure your device supports these bands for optimal performance.

  1. KYC requirements for eSIM activation

To activate a Taiwan eSIM, you must provide a valid passport or national ID. Some providers may require a selfie or video verification. Roami simplifies this process with pre-verified profiles.

  1. Fair Usage Policy (FUP) for unlimited plans

Most unlimited data plans in Taiwan have a Fair Usage Policy (FUP) that throttles speeds after a certain data threshold (e.g., 50 GB per month). Check the specific plan details before purchasing.

  1. eSIM compatibility with your device

eSIM is supported on iPhone XS and newer, Google Pixel 3 and newer, Samsung Galaxy S20 and newer, and many other Android devices. Verify your device’s eSIM compatibility before travel.

  1. Roaming vs local eSIM: cost comparison

Using a local Taiwan eSIM like Roami is significantly cheaper than international roaming. For example, a 7-day unlimited data plan costs around $15 USD, while roaming can cost $10-20 per day.
