Code eSIM is a travel eSIM store built for people who want mobile data ready before an international trip. We help travelers compare eSIM options, check phone compatibility, install an eSIM before departure, and choose a data plan for destinations such as China, Japan, Korea, Thailand, Europe, the United States and other travel regions.
Our focus is practical travel connectivity. A good eSIM should be easy to understand before purchase: where it works, how much data it includes, how long it lasts, whether hotspot is supported, when it activates, and what to check before installation.

Before You Buy
Before buying any eSIM, check whether your phone supports eSIM and is carrier-unlocked. Some phone models and purchase regions have special rules, especially for mainland China iPhones. If you are not sure, start with the eSIM compatibility guide.
For setup, use the eSIM installation guide. In most cases, it is safer to install the eSIM while connected to reliable WiFi before departure, then enable the travel eSIM data line after arrival.
Important Service Notes
Most travel eSIM products are data-only unless the product page clearly says calls or SMS are included. Network speed and availability can vary by local coverage, device, plan, building, terrain and network conditions.
For China-related eSIM content, Code eSIM may discuss app-access scenarios and no-extra-VPN-app setup flows. These notes should be understood as travel connectivity guidance, not as a guarantee that any specific third-party app, website or AI service will always work. Third-party app availability can change and may depend on the app provider, account status, network route, device settings and local conditions.
Help and Policies
For support, installation questions and common troubleshooting steps, visit the Code eSIM help center. For refund boundaries, review the refund policy before activation or installation.
Code eSIM aims to make travel data easier to compare, buy and set up before the trip, so travelers can spend less time looking for SIM counters and more time moving through their itinerary.
