Solution 1: Fully Unlimited Outside Fujian Province
This solution offers full-speed internet without restrictions when used outside Fujian Province. You can directly use it as long as the dedicated commuter data (“通勤流量”—a special data package for use within Fujian Province, primarily for commuting between home and work) remains unused. The effect is that it may display a speed limit notification, but in reality, the speed is not restricted.

Additional Details: Campus data plans (including the 2019 version and the current version) allow free subscriptions to two commuter data packages, 20 GB and 50 GB respectively. Other users generally need to pay, although some non-campus users have successfully subscribed.

Solution 2: APN Method
For this method, standard iPhones cannot modify the APN settings. You'll generally need an Android device, MiFi, or CPE device to change the APN. Set the APN to either "CTWAP" or "CTLTE." Note that this method only works with 4G networks. According to online information, "CTWAP" usually works but may have compatibility issues.

Solution 3: Dianqu Data Packages
Dianqu (“电渠”—referring to electronic channel data packages, essentially online data packages) involves subscribing to several free telecom channel data packages after the speed limit is imposed. Once successfully subscribed, use up the data before the telecom detects and reacts. The smaller the package, the better, as they lift the speed limit with minimal delay. Small packages range from 100 MB to 200 MB (these are related to a promotional data package called "Data Garden" that was removed a few months ago; currently, only third-party sources offer links for free subscription). Larger packages can reach 1 GB or 2 GB, and you can find some available packages at https://www.lwy.me/icp/.

Solution 4: Expiring Short-Term Data Packages
Subscribing to a short-term data package (often a daily package) can sometimes temporarily lift the speed restriction. Although not all packages support this, those that do will specify in their description that speed will be restored for “畅享” plan users who are currently speed-limited. This method may involve some trial and error, as the effectiveness of specific packages can vary, and there is an increased failure rate for provincial packages. It seems that the cheapest option is a 3 RMB package valid for one day.

Additional Notes:

Typically, you need a data plan that supports unlimited data (including a usage threshold that triggers a speed limit). These plans often include the word “畅享” (meaning “Enjoy”) in the package name. In the package description, domestic data is shown as “畅享” rather than a specific data cap, and data usage displays as "used data" instead of "remaining data." Additionally, subscribed services might include a “畅享功能流量包.”

  • Understanding Key Terms:
    • “通勤流量” (Commuter Data): A special data package available within Fujian Province, intended for regular commuting between home and work.
    • “电渠” (Dianqu): Refers to electronic channel data packages, which are essentially online data packages available through digital channels.
    • “畅享” Plans: Data plans that offer unlimited data with a speed limit after reaching a certain usage threshold. The term “畅享” means “Enjoy” and is often included in the package name.
    • “畅享功能流量包”: An additional service package that may be included with “畅享” plans.
  • Requirements for Best Results:
    To effectively lift speed limits using these solutions, it's generally necessary to have a data plan that supports unlimited data with speed restrictions after a certain threshold. The plan should display domestic data as “畅享” instead of a specific data limit, and data usage is typically shown as "used" rather than "remaining."
