eSIM is really hard to change device in Taiwan due to government (NCC Department) "instructions" (that carrier sometimes misinterpreted it):

  • Can not transfer by yourself, you need to go to carrier to transfer.
  • 300 NTD (~10 USD) per move (can be waived under some cases)
  • Might deny if you move too often recently.
  • ~~And now (actually start few days ago), you need to show proof of purchase (or gift) of the target device. Carrier can deny if you fail to do so, and they'll say they're following government instructions.~~ NCC said it should not be applied to eSIM as it's one-time use only, but such rule already executed for few days and caused troubles for some people.

So physical SIM is more flexible here. (For now)

EDIT: NCC Department said the instructions are just suggestions, carrier should do KYC properly, but how all major ones do the same annoying stuff is beyond me...

EDIT 2: NCC Department clarified the new KYC instructions. (Chinese) 媒體揭露KYC指引相關報導恐有誤解，NCC今日邀集三大電信業者溝通說明，持續滾動因應實務情形
