@China Mobile responds to garbled SMS questions:
Unicom Shandong Branch conducted system upgrade tests
According to the official blog news of China Mobile, on the evening of April 28, 2022, some customers in the 136 section received a garbled text message from the number beginning with 130 (the 8 digits after the caller number are consistent with the 8 digits after the called number), and after discovering the problem, China Mobile immediately launched the emergency response process to intercept the relevant text messages. After verification with China Unicom, the reason was caused by the system upgrade test conducted by China Unicom Shandong Branch, and China Unicom has quickly disposed of it accordingly after locating the cause. China Mobile will further enhance its emergency service capabilities and provide customers with quality services.

Such text messages
Send a mobile phone number starting with 130

Subsequently, this "weird text message"
It sparked a heated discussion on Weibo
Some netizens found
"It's as if 136 numbers all over the country have been received"
"My number of 136, a number of 130,
The other numbers were exactly the same."
There are also concerns about personal information being leaked
The strange text message received has the 136th and 137th segments; the sender is basically the 130th segment, and the difference with the number of the 136th segment is very small; many netizens say that the last 8 digits are the same, in other words, the difference between the two numbers is only one digit. It is understood that 136 is mainly a mobile number segment, and most of the 130 belongs to the Unicom number segment.
