Dopod s 1 sends a text message? How to deal with the number

I'm a little confused about the problem upstairs. I don't know whether it is the question mark of the input method or the question mark on the received short message, but the display failed when the short message was sent! Will there be a question mark?

Or the input method? Number.

Is it a point message input method? See a question mark on the button of def? Pull up the question mark and go up!

If it still doesn't work, click Help in the lower left corner of the input method. Look at the explanation!
