How can I get the other person to send a text message instead of his own mobile phone?

This is impossible! There is only one way to stop you from texting (press SMS settings to find the "information center number" and then press settings: you can't text if you don't want to reply to SMS! Just fill the memory of your mobile phone with short messages! Ignore the messages you receive. After the memory is saturated, SMS can't be sent any more! You don't have to worry that the mobile phone system will keep this information for you! In fact, the system only helps you keep the information for one day, and then it will be automatically deleted!
