Why does the mobile phone keep receiving text messages of 00447786205094, and it is a mess of English letters?

If the SMS center does not receive the response message, it will be sent repeatedly.

Solution steps:

1, change the phone and test to see if there is any problem of receiving SMS repeatedly.

2. Change the area and test in the areas with good signal and poor signal respectively. If it is a signal coverage problem, it is recommended to complain to the operator.

3. Both tests were abnormal, so it was the operator's data configuration problem and complaint handling problem.
