What does it mean that Apple's mobile phone text message shows that it has been sent with fireworks?

Apple's mobile phone text message shows that it has been sent with fireworks, which means:

Apple's mobile phone text messages are all sent with fireworks special effects.

The reason why Apple's mobile phone can't receive SMS may be:

When the local base station delivers or closes the station, voice and short messages will not be received at this time.

Local mobility and connectivity can limit network traffic and time and block content.

Rule out the factors of mobile phone shutdown or extended downtime, and then check whether your mobile phone card will be blocked by operators such as China Mobile or China Unicom, because there is a speed limit for mobile companies to send text messages at present. If more than 100 SMS messages are identified as SMS advertisements within an hour, the number will be blocked.

Poor regional signal or mobile phone quality problems can also lead to the failure to receive short messages. Nowadays, many smart phones also have the function of blocking strange short messages.
