When playing mobile games, I was asked to send text messages. When texting, you are still required to connect to the Internet. As a result, the fee was not deducted after a few days.

Well, the short message charging platform of game makers is probably invalid, so there was no charge for sending short messages in the past.

Generally speaking, if the SMS is charged, the successful SMS will reply. If not, it is likely that there is something wrong with the charging platform, and of course there will be no charge deduction.
