Scrolling through MWC news and ended up discovering this eSIM from CUniq 📱🌍
I was casually browsing updates from Mobile World Congress 2026 and saw that China Unicom Hong Kong CUniq had a pretty big presence at the event in Barcelona.
That’s how I ended up looking into their eSIM service, and honestly it looks quite convenient.
No physical SIM card. No store visits. Just scan a QR code and you’re connected.
For people who travel frequently between Hong Kong and Shenzhen, this actually sounds really practical — land, activate, and get online immediately.
I also noticed their eSIM app CUniqGO currently has a promotion:
✨ Register an account and purchase an eSIM over $50 ✨ Use code ESIMAPP for 10% off
The promo runs until April 30, 2026, and once you claim the code it will appear in your account.
I tried ordering one right away — seems like a pretty handy option for travel or cross-border trips.
