These days, I always get spam messages with the same content. The content is as follows. What happened? Who can tell me?

Due to the following reasons, the received SMS appears garbled:

1. The format entered by the sender user is incorrect;

2. The version of the receiver's mobile phone system may be too old, so that the received message cannot be displayed normally. Please upgrade your mobile phone operating system.

3. Pictures sent online or ringtones downloaded, but this format is not supported by mobile phones.
