true identity registration
You may have received a text message that looks like one of the ones below.
For those who can’t read Chinese, this message is informing us that China Mobile will be enforcing China’s “true identity registration” policy. If your cell phone is registered to any other name than your own, your service will be suspended. In order to continue service instructions are given about how to register your number to your personal document so that service isn’t interrupted. (take your ID to China mobile or follow the links provided in the message to do it online).
If your phone is already registered to your name you don’t need to do anything.
China Wire also posted this article about phone service being suspended for users with foreign messaging apps.
It may seem like an inconvenience if you have to register, but I’m sure not having cell service is inconvenient too.
