Taipei

The network speed is good, the user experience is great, it's cost-effective, and the eSIM means you don't need to change your SIM card, which is very convenient.

I was traveling with a friend and we were making a round trip between Taipei and Kaohsiung. After comparing the prices of both options, I decided on this one because it was 30% off. While advance train and seat reservations are possible via the app and redeeming the High-Speed ​​Rail tickets within the app, and then booking through the High-Speed ​​Rail official website the day after redemption, I couldn't book adjacent seats in Japan because each person received a separate High-Speed ​​Rail Redeem number (perhaps due to individual pass issuance). In reality, we were able to secure adjacent seats at the station ticket counter the day before, so there were no problems. We also redeemed our subway tickets at the station. I didn't have a chance to use the Taiwan Tourist Shuttle bus, but if you're planning a round trip between Taipei and Kaohsiung (or now Taipei and Tainan), I think it's worth considering. Using it is similar to the 15% discount for foreigners; you show your passport to the station attendant at the ticket gate. Please note that the carriage and seat numbers are handwritten by the station attendant, so they may be difficult to read.

This esim is easy to use, buy and use, and do not need real name authentication, the speed is acceptable, the price is cheap and can use any data, cheap and good

Used in Taipei and Taichung. The speed was sufficient, and translation and AI worked smoothly. Setup was easy, and if you have trouble connecting, you can use the free Wi-Fi at the arrival airport to get instructions via chat. It's incredibly cheap compared to domestic carriers' international roaming, so I recommend it for people who don't need to make phone calls.
