Answer first
A CN-3 eSIM is a practical choice when you need prepaid mobile data without swapping a physical SIM or relying on public Wi-Fi. eSIMFlux currently shows 9 purchasable options from $4.54, with data choices of 1GB - 20GB + day passes and validity of 1 - 30 Days. Plans use partner networks such as local partner networks; the network you actually join depends on the package, location, device, and signal available. Installation is digital, and validity normally begins when the eSIM first connects to a supported network. The plans are data-only, so use WhatsApp, FaceTime, or another internet calling service rather than expecting a local phone number. Before buying, confirm that your device supports eSIM and is carrier unlocked. To prevent charges from your home operator, choose the travel eSIM for cellular data and disable data roaming on your primary SIM. Always confirm the live price and plan details at checkout.
These are prepaid, data-only plans delivered digitally. They do not replace your primary number, so you can keep your usual SIM active for calls and use the travel eSIM for mobile data. Your phone must support eSIM and be carrier unlocked.
Available plans can connect through local partner networks. 5G is available only where the selected package, device, and local network support it; otherwise the connection uses 4G LTE. Coverage still varies by location and network conditions.
Use a smaller fixed-data plan for maps, messages, and occasional browsing. Choose more data or a daily-allowance plan for video calls, frequent uploads, or hotspot use. Compare the live table above before checkout because inventory and prices can change.
Select the eSIMFlux line for mobile data and turn off data roaming on your primary SIM. Some travel eSIM packages require data roaming on the travel eSIM itself; follow the installation details delivered with your plan.
