Cool Android phone calls, there are text messages that refuse to get rid of.

This should not work, because SMS rejection is a new rejection method designed for user experience, especially in smart phones and mobile phone systems. You can, as the netizen upstairs said, remove the SMS rejection, see if the dial panel is set, or see if there are related call settings in the mobile phone settings; Also, if it is an Android phone, it should be done by brushing the rom package, provided that the rom has been modified and there is no SMS rejection.
