The smart way to stay connected

With this China, Hong Kong and Macau eSIM, your SIM lives digitally inside your phone, so you skip kiosks, plastic cards, and swapping trays. After you choose your data package duration, you receive a QR code that you add to your compatible, unlocked device using a stable internet connection. Once the eSIM connects to a supported network in Thailand, your plan validity starts, and you are online for the selected 3 to 15 days. You keep your usual physical SIM in place, while this eSIM quietly handles your travel data in the background.

Benefits, convenience and more

You use fast 4G or 5G data for maps, browsing, TikTok, ChatGPT, and staying in touch throughout your trip, subject to local coverage and device support. There is no local number, so you focus purely on data. Hotspot use is supported, which helps if you want to share your connection with a laptop or another phone. Since everything is handled by QR code and instant activation, you stay connected without arranging different local SIMs.

Check your email for the QR code and information from the supplier.

Scan the QR code using your phone, following the on-screen steps.
