Sigma Mobile Is Now a Proud Member of Club France International (CFI)

Some communities are built around geography. Others are built around the people who choose to build a life far from home, together. Club France International is the latter — a network of French professionals and expats spanning Hong Kong and beyond, supporting each other through business, connection, and shared experience abroad.

We're proud to share that Sigma Mobile is now a member of CFI International / CFI Hong Kong.

Why This Membership Matters to Us

Connectivity is easy to take for granted until you're the one without it — standing at a border crossing between Shenzhen and Hong Kong, trying to explain a local SIM registration process in a language you don't speak, or watching WhatsApp fail to load the message from home that actually matters. For the expat and business community CFI represents, that friction is a familiar, recurring cost of living and working across the Greater Bay Area.

Joining CFI isn't just a partnership on paper. It's an opportunity to put Sigma Mobile's connectivity directly in front of the community it was built to serve — French professionals, entrepreneurs, and families navigating life between mainland China, Hong Kong, and Macau.

What Sigma Mobile Offers the CFI Community

Our China, Hong Kong & Macau eSIM is built specifically for this kind of cross-border life:

• One eSIM profile, three destinations. Mainland China, Hong Kong, and Macau covered on a single data plan — no swapping SIMs at the border.
• Unrestricted access. Data is routed so that Google, WhatsApp, Gmail, Instagram, banking apps, and everyday productivity tools work the way they do at home — no VPN required.
• Instant setup. A QR code arrives by email within minutes of purchase. Activate before you fly, or the moment you land.
• Dual-SIM friendly. Keep your existing phone number and WhatsApp account active on the same device while data runs on the eSIM.
• Hotspot and tethering supported, for sharing a connection with family or colleagues.

Whether it's a board meeting in Shenzhen, a weekend visiting family in Macau, or simply staying reachable for the people back in France, the goal is the same: connectivity that doesn't interrupt how you actually live and work.

An Exclusive Offer for CFI Members

As part of this membership, CFI members receive special conditions of any Sigma Mobile eSIM plan-  including our GBA-focused China, Hong Kong & Macau plan, as well as any of our 100+ other global destinations.

Looking Ahead

We're looking forward to being part of the CFI community — supporting events, sharing practical connectivity solutions, and getting to know the people who make up this network. If you're a CFI member and haven't tried Sigma Mobile yet, this is a good place to start.
