Re: Sms messages (in-out). What functions do I need?
To send and receive SMS messages, you will need a device or application that is capable of communicating with a mobile network using the Short Message Service (SMS) protocol. This typically involves using a mobile phone or a computer with a mobile broadband connection and SMS messaging software.
To send an SMS message, you will need to use a function that allows you to specify the recipient's phone number and the content of the message. The function should also allow you to specify any additional options or settings, such as the sender's phone number or an option to send the message as a multimedia message (MMS).
To receive SMS messages, you will need to use a function that allows you to listen for incoming messages and process them when they arrive. This function should allow you to specify a phone number or other identifier to listen for messages from, and should provide a way to access the content of the message and any other relevant information, such as the sender's phone number or the time the message was received.
Depending on the platform or programming language you are using, there may be different libraries or APIs (Application Programming Interfaces) available for working with SMS messages. For example, if you are using a mobile phone with a built-in SMS messaging feature, you may be able to use functions provided by the phone's operating system to send and receive messages. If you are using a computer, you may need to use a third-party library or API to communicate with a mobile network.
