Does my phone support eSIM?▼
iPhone XS or later (2018+), Samsung Galaxy S20+, Google Pixel 3+ — most flagship phones from 2018+. Dial *#06# — if a 32-digit EID shows, your phone supports eSIM. Full list on the Compatible Devices page.
How do I install? Do I need Wi-Fi?▼
Wi-Fi is required to download the eSIM profile. iPhone: Settings → Cellular → Add eSIM → Use QR Code. Android: Settings → Connections → SIM Card Manager → Add mobile plan. Takes 2-3 minutes.
Is it instant? When does the QR code arrive?▼

Can the eSIM make calls or receive SMS?▼
It's data-only. Use WhatsApp, LINE, Telegram, FaceTime for calls. For bank/work SMS, keep your physical SIM active in parallel.
What if I can't connect after install?▼
1) Confirm Data Roaming is on; 2) Set the new eSIM as the default data line in Settings; 3) Restart your phone. Still stuck — WhatsApp our Hong Kong support team.
What's the refund policy?▼
**Unactivated** eSIMs: full refund within 7 days. **Activated** eSIMs (QR scanned and profile downloaded): non-refundable per industry standard — the carrier has consumed the provisioning. See the Refund Policy page.
