Does it work on the High-Speed Rail and at Alishan or Taroko Gorge?

The ETravelSim Taiwan eSIM works along the High-Speed Rail (HSR) corridor connecting Taoyuan, Hsinchu, Taichung, Tainan, and Zuoying, with strong handover between cells at full HSR speed. Coverage holds at Alishan's main forest railway stations and the Taroko Gorge tourist viewpoints. Expect signal drops in deep mountain trail sections, inside Taroko's longer tunnels, and on remote forest roads — this affects every Taiwanese carrier equally.
