"PassiveSms" enables you to prepare personal SMS messages, addressed to specified callers at pre-prepared time sections chosen by you.
If the phone call is from a specified caller, at a pre-prepared time section and if you do not answer that call – he will get the personal message you've prepared for him.
A "PassiveSms" message will NOT be sent in each of the following situations:
The phone call is from a caller for whom there are no prepared messages.
The phone call is from a caller for whom there is a (are) prepared message(s), but the time when he calls is not at any of the time sections prepared in advance.
The phone call is from a caller for whom there is a prepared message and it is during an appropriate time section, but you answer the call.
It is possible to prepare various SMS notes to the same potential caller in various time sections.
"PassiveSms" is connected to your contact list. You may define each caller either by his/her phone number or by his/her name. When you add a new caller, his name will be automatically completed from your contact list.
"PassiveSms" will assist you in avoiding errors, e.g. it won't enable you to leave two distinct SMS messages to the same caller in overlapping time sections.
There is a wide variety of daily situations when you don't want to contact someone or send someone a message, but you prefer to respond with SMS only in case he calls.
