UnlimitedOnDemand Auto Reply

This simple Android app was created with one specific purpose in mind: to automatically respond to incoming SMS messages with a customizable text. As the app's name suggests, it's designed to automatically reply to those persistent SMS messages from your mobile network provider, which you need to respond to in order to maintain high-speed data connection.

Due to limitations in modern Android, where receiving SMS in the background is not possible unless the app is set as the default SMS app, this application utilizes notifications to check for incoming messages. This means the app will only function if your default SMS app provides notifications for incoming messages.

When a notification from a specific app (ideally your default SMS app) with a specific title and text containing a predefined string is detected, the app automatically sends an SMS with a customizable message to a designated number.

Please be aware that your network operator may prohibit the use of such automation in their terms and conditions. To make the automation less noticeable, the app will introduce a randomized delay before sending the reply, with the delay time customizable within a specified range.

I should also note that while this app can automate the described task, it should be regarded strictly as a testing tool and a proof of concept. Surely, no one should rebel against the intentions of network operators...
