eSIM China Unlimited Data

Every calendar day you receive 1 GB of high-speed data on the China Telecom network. Use it for cloud uploads, video calls, social media posts—whatever your workflow demands. When that gigabyte is spent, the connection does not stop. Instead, speed falls to 128 Kbps for the remainder of the day.

At 128 Kbps you can still load maps, send text messages, receive emails and check schedules. Video streaming and VoIP calls will not work at this speed; that is intentional, and knowing it upfront saves frustration. The quota resets at midnight UTC+8—that is a fixed moment in UTC, not midnight where you are, so check your phone's UTC offset if you plan around it.

This is a data-only eSIM. There is no phone number, no voice minutes, no SMS capability. If you need to make calls, use an internet-based app while you still have high-speed data available.

Choose China Unlimited when: your daily data use spikes and dips unpredictably. Photographers uploading batches of RAW files in the morning can burn through 1 GB fast, then coast on throttled data for navigation and messaging the rest of the day. Business travellers who need a reliable fallback for email and maps—even after a video call eats the quota—will appreciate the no-cut-off safety net. Short trips of a week or less fit the available validity windows perfectly.

Consider the standard data plans instead when: you need consistently high speeds throughout the day, or your trip exceeds seven days. The longest Unlimited bundle is 7 days, and the line cannot be refilled. If you are streaming video regularly, joining long conference calls, or staying in China for two weeks, the regular eSIM catalogue on our China offers larger fixed data pools and longer validity without daily resets.

This plan covers a single country. If your trip takes you elsewhere - or you are still comparing destinations - see every country with an unlimited data eSIM and pick the one that matches your route.
