Why does SMS automatically convert to MMS? How many words are automatically converted into MMS?

Generally, short messages on mobile phones are automatically converted into MMS because there are too many words. If they are all words, they will not be automatically converted into MMS. If you forward it to MMS, it means that SMS contains pictures or pictures-like words.

The maximum number of short messages on most mobile phones is 268 or 270. If it exceeds this length, the system will automatically cut it when the message is sent. Or the content of the short message has an attachment and is sent as a file.
