Frequently asked questions
Do I need a physical SIM card to use mobile data in Taiwan?
No. A Siima eSIM gives you local data in Taiwan without a physical card. Activate by scanning a QR code in your phone's settings — no shop visit, no passport check required.
How do I activate my eSIM when I arrive in Taiwan?
Install the eSIM before you travel: open Settings → Cellular → Add eSIM and scan the QR code from your Siima confirmation email. Your data activates automatically when you first use mobile data in Taiwan.
How much data do I need for a trip to Taiwan?
For light use (maps, messaging, email) 1–3 GB per week is usually enough. For streaming or heavy navigation, choose a 5 GB+ plan. You can buy additional plans at any time if you run low.
Is eSIM cheaper than international roaming in Taiwan?
Almost always yes. International roaming from most home carriers costs $10–15 per day. Siima eSIM plans for Taiwan start from $4.92 and cover days or weeks of local data.
