Carrier | Effective date | Announcement |
China Mobile | December 1, 2025 | [November 18, 2025] China Mobile's controls on redirection information in messages |
China Mobile | July 10, 2025 | China Mobile's controls on SMS template registration and referral information |
China Unicom | June 30, 2025 | China Unicom's controls on SMS template registration and referral information |
China Telecom | May 30, 2025 | |
China Telecom | May 20, 2025 | China Telecom restrictions on SMS content containing URLs, IP addresses, and contact information |
Because carriers implement policies at different times and with varying levels of enforcement, SMS messages that contain traffic diversion information, such as URLs or contact information, may be delivered by some carriers but fail to be delivered by others. Enforcement strictness also varies by province, and actual blocking results are subject to notices from provincial carriers. To ensure delivery across all three carriers, use templates that do not contain URLs.
The above interception and control measures for traffic diversion messages are ongoing policies. No operator has announced a timeline for resumption or lifting of these restrictions. Specific implementation is subject to actual notices from provincial operators.
