Can I send a text message even if I turn off the data?

A. 1

It's possible for short sentences.

OK

You can turn off the data with a short sentence of 80 to 90 characters.
If it goes beyond that, or if you send an image or video, it becomes mms, but in the case of mms, you must turn on the data to send it.

Basically, mms is possible only when the data is turned on as mentioned above, and it seems that some of the data is used.
But if you take the data out of the carrier's plan, there's a problem with how you can use it without the data
In this case, the carrier provides data for free for data generated in mms.
