Frequently asked questions

Your eSIM connects to Taiwan's leading 4G/5G networks, including Chunghwa Telecom and Taiwan Mobile, giving you strong coverage across Taipei, Taichung, Kaohsiung, and rural and mountain areas.

Yes. Coverage extends to Taiwan's outlying islands, though signal strength in remote areas can vary the same as it does for local SIM users.

Our eSIM plans are data-only. Keep your home SIM active (or set it to data roaming off) to keep receiving calls and SMS on your original number while using our eSIM purely for data.

Most phones from the last five years support eSIM, including iPhone XS and later, Google Pixel 3 and later, and recent Samsung Galaxy S/Note/Fold models. Check Settings > About Phone, or search '[your phone model] eSIM compatible' to confirm.

Your phone must be carrier-unlocked to install a third-party eSIM. If you're unsure, contact your current carrier or check your device settings for a 'SIM lock' status.

Yes — that's the main benefit of eSIM. Most modern phones support Dual SIM Dual Standby (DSDS), so you can keep your home number for calls/SMS and use our eSIM for Taiwan data simultaneously.

You can purchase a new plan at any time from the Shop page. There is no auto-renewal — you stay in control of what you spend.

Your plan's validity period starts the moment the eSIM connects to a network in Taiwan, not at the time of purchase, so you can buy in advance without losing days.

Currently each purchase provisions a fresh eSIM profile. If you need more data on the same trip, simply install a second plan — most phones support multiple eSIM profiles.

If your eSIM has not been activated (i.e., never connected to a Taiwanese network), you're eligible for a full refund within 30 days of purchase. Once activated, plans are non-refundable. See our Terms page for full details.
