- You can scan the QR and install the eSIM before you travel. Days start counting when you arrive in Taiwan, and you must activate it within 60 days of purchase.
- Moderate use is about 1.5 GB a day: 10 GB is enough for 5 days. If you don't want to count data, or you watch a lot of video, pick Unlimited.
- Every plan runs on 5G on Chunghwa Telecom and Taiwan Mobile. You can check your remaining data and top up without changing SIM.
- Every plan allows hotspot sharing. They are data only, with no phone number for calls or SMS. If you want faster than 10 Mbps, Vacay also sells a full-speed option: 5GB a day at full speed, then 10 Mbps.
