SMS has changed in Android 4.4. This means that if I add SMS now it will only work on Android 4.4 and higher. Also, now, only one app can receive a new SMS_DELIVER_ACTION intent, which the system broadcasts when a new SMS message arrives. Which app receives this broadcast is determined by which app the user has selected as the default SMS app in system settings. Other apps that only want to read new messages can instead receive the SMS_RECEIVED_ACTION broadcast intent when a new SMS arrives. However, only the app that receives the SMS_DELIVER_ACTION broadcast (the user-specified default SMS app) is able to write to the SMS Provider.
This means that you would need to set Mintoris Basic as your default SMS program. I don't think this is very practical since your normal SMS app would stop working. I could put in the ability to monitor SMS messages, but then you would not be able to send messages.
