Step-by-step
Follow these steps
Check your phone support
Confirm your phone supports eSIM and is unlocked. Some phones or regions may not support eSIM.
Choose a data option
Compare international roaming, travel eSIM, or local SIM. Travel eSIM is often convenient for short trips.
Install before departure
Install and test the eSIM before your flight, but activate it according to the provider instructions.
Save offline backups
Save hotel addresses, screenshots, tickets and emergency contacts in case data is slow after landing.
Test key apps
Check maps, translation, Alipay, WeChat, Trip.com and Didi once connected.
Keep a backup plan
Hotel Wi-Fi, airport Wi-Fi, roaming or a second eSIM can help if the first option fails.
