SoSIM 365-Day Greater China 10GB | Generated by AI
Question: What is the SoSIM 365-day Greater China 10GB card?Answer:
SoSIM is a prepaid eSIM/SIM brand launched by Hutchison Telephone Company Limited (3HK) in October 2020, providing contract-free prepaid SIM card services in Hong Kong.
The Greater China 10GB / 365-day plan specifically is part of their “Ai Travel SIM” product line:
- Price: HK$138 one-time, no monthly fee
- Data: 10GB roaming data usable in mainland China, Macau, and Taiwan
- Validity: 365 days after activation
- Bonus: Comes with FREE 5GB Hong Kong data (30-day)
- Format: eSIM — activate by scanning a QR code, set up in as fast as 10 minutes. No physical SIM needed, easy to switch networks, won’t be physically lost or damaged.
- Purchase: Online via sosimhk.com
Why it makes sense for your use case (occasional mainland roaming, no monthly commitment):
- No recurring charges — pay once, use across a full year
- ~HK$13.8/GB effective cost for mainland data
- Works alongside your existing primary SIM (dual SIM / eSIM slot)
- No VPN headache for basic connectivity in mainland (routed via HK carrier)
Gotcha to know: The 10GB is shared across mainland China + Macau + Taiwan for the full year, so it’s genuinely only suitable for occasional/light usage — not daily work traffic.
