Coverage & connectivity.
Hong Kong has one of the world's densest 5G networks — effectively blanket 5G across Hong Kong Island, Kowloon, and the New Territories. The MTR (Mass Transit Railway) has full 4G/5G in all underground stations and tunnels, including cross-harbour tunnel segments. Hong Kong Island (Central, Causeway Bay, Wan Chai, Aberdeen), Kowloon (Mong Kok, Tsim Sha Tsui, Sham Shui Po), Lantau (Tung Chung, Disneyland), and the Outlying Islands ferry terminals all have strong 5G. Hiking trails on Dragon's Back, Lion Rock, and Lantau Peak have 4G on accessible sections; very high ridgelines may have variable signal. Cheung Chau, Lamma, and Lantau island-wide are covered at the main settlements.
Questions about Hong Kong
Does the Hong Kong MTR have underground coverage?
Yes — full 4G/5G throughout all MTR stations and tunnels, including the cross-harbour tunnel. Coverage is flawless on every line.
Is Lantau Island and Disney covered?
Yes. Lantau has island-wide coverage. Hong Kong Disneyland, Tung Chung, and the Ngong Ping 360 cable car area all have strong 4G/5G.
Will this work on the Star Ferry?
Yes. Victoria Harbour is fully covered — both Star Ferry crossings (Tsim Sha Tsui to Central/Wan Chai) have full 5G throughout the journey.
How does pricing compare to Airalo Hong Kong?
Flysimio is typically 40–50% cheaper for equivalent Hong Kong plans on the same CMHK or SmarTone network.
Does this work in Macau?
Your Hong Kong eSIM covers Hong Kong only. For Macau, purchase a separate Macau eSIM or a China+Macau+HK multi-region plan.
What is an eSIM?
An eSIM (embedded SIM) is a digital SIM built into your phone. Instead of a physical card, you scan a QR code and your plan installs instantly — no SIM tray needed.
Is my phone eSIM-compatible?
iPhone XS (2018) and newer, most Android flagships from 2020+, and all Samsung Galaxy S21+ devices support eSIM. Check our compatibility page for the full device list.
How do I install the eSIM?
After purchase, we email a QR code. On iPhone: Settings → Cellular → Add eSIM → Scan QR Code. On Android: Settings → Network & Internet → SIMs → Add eSIM. The whole process takes under 60 seconds.
Can I keep my regular SIM while using this eSIM?
Yes. Most phones support dual SIM (physical + eSIM). Keep your home number for calls and SMS — use Flysimio for data abroad. You control which SIM handles what in your phone Settings.
Does the eSIM include a hotspot (tethering)?
Yes, all Flysimio plans include mobile hotspot at no extra charge. Share your data connection with laptops, tablets, or other devices freely.
What happens when my data runs out?
You can top up data from your account dashboard at any time. Top-ups are applied instantly — no need to buy a new eSIM or wait.
Can I get a refund?
Yes. We offer a full refund within 7 days of purchase. Contact contact@flysimio.com with your order number.
How long is the eSIM valid for?
You have 6 months from your purchase date to activate the eSIM. Once activated, the plan validity period (e.g., 7 days, 30 days) begins counting down.
Will the eSIM work at the airport when I land?
Yes — as long as you installed the eSIM before your flight, it activates automatically when your phone connects to a local network on landing. No Wi-Fi required for activation.
What if the QR code doesn't scan?
If the QR code won't scan, you can enter the activation code manually — we include both in the email. You can also contact our 24/7 support team and we'll resend or manually provision your eSIM.
