Why is 3HK the Professional's Choice?
3HK (Three Hong Kong) is a direct carrier eSIM, not a reseller or aggregator. This means you're getting a genuine Hong Kong mobile number and IP address, directly from one of Hong Kong's major telecommunications providers.
For users who need verified Hong Kong credentials—banking, business services, or HK-specific applications—3HK is the only option that provides authentic, carrier-direct infrastructure.
What Does "Native Hong Kong IP" Mean?
Unlike aggregator eSIMs (Airalo, Nomad) that may route through various gateways, 3HK provides:
- Real HK IP Address: Essential for services that geo-verify Hong Kong users (banking apps, streaming services, enterprise VPNs)
- HK Phone Number: Receive SMS for HK bank verifications and two-factor auth
- Carrier-Grade Infrastructure: No middleman latency or routing inefficiencies— your traffic goes directly to Three HK's network
How Do I Configure 3HK?
3HK may require manual APN configuration on some devices:
APN: mobile.lte.three.com.hk
Username: (leave blank)
Password: (leave blank)
Authentication: None
On most modern iPhones and Pixels, the eSIM will auto-configure. If you experience connection issues, manually entering the APN typically resolves them.
Strengths and Limitations
Strengths
- ✓ Real HK IP: Essential for banking and HK-specific services
- ✓ HK phone number: Receive SMS for 2FA verification
- ✓ Carrier-direct: No middleman, lowest latency to HK
- ✓ China Unicom roaming: Better AS4837 routing
Limitations
- ! Complex setup: May require manual APN configuration
- ! Official channels: Must purchase from Three HK
- ! HK address: Some plans require HK address for activation
- ! Price variability: Pricing depends on plan selection
Why Does China Unicom Roaming Matter?
3HK roams on China Unicom towers within mainland China. This is advantageous because Unicom's AS4837 network generally offers better international routing than China Mobile's CMNET, particularly for users in coastal cities.
For users in Southern China (Shenzhen, Guangzhou), 3HK provides optimal latency—often 20-30ms to Hong Kong servers, the lowest of any eSIM option.
Who Should Use 3HK?
- Users needing a verified Hong Kong IP for banking and business services
- Business users requiring HK phone number for SMS verification
- Technical users who prefer carrier-direct solutions over aggregators
- Users in Southern China who want the lowest possible latency
- Professionals needing enterprise VPN access that requires HK IP
Not ideal for: First-time eSIM users, those wanting simple one-click setup, or users without a way to purchase from official Three HK channels.
Purchase Note
3HK eSIMs should be purchased from the official Three HK website or from authorized resellers. Avoid third-party marketplaces to ensure you receive a legitimate, properly activated plan.
