Frequently asked questions
Do I need a physical SIM card to use mobile data in Hong Kong?
No. A Siima eSIM gives you local data in Hong Kong 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 Hong Kong?
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 Hong Kong.
How much data do I need for a trip to Hong Kong?
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 Hong Kong?
Almost always yes. International roaming from most home carriers costs $10–15 per day. Siima eSIM plans for Hong Kong start from $3.89 and cover days or weeks of local data.
