SMS Profit is a smartphone app that allows you to receive SMS messages to your number, in order to test and improve mobile communications. In practice, mobile phone operators are helped and for each message received, you get a small fee on your SMS Profit account.
All you have to do is receive SMS text messages on your mobile once in a while.

After installing the app by downloading it 
and registered your mobile number, SMS Profit will send random test SMS from time to time and you will earn money for each text message received.
Before installing the APK package, the "Unknown sources" option must be enabled on the smartphone through the "Settings -> Security" menu on the device.
It only works on smartphones with an Android operating system (version 5.1 or higher), because Android allows you to process the results of test SMS messages that are sent.

SMS Profit is extremely secure and personal data is managed according to the privacy regulations.

It is not possible to choose whether to always receive messages or only on certain days or time slots. If you do not want to receive messages for a while, simply deactivate the app in the smartphone settings (Application manager).

Once the SMS message has been received, it can be deleted (it is not necessary to store it).
The messages do not contain any meaningful text but only some random characters that we can ignore.

The amount of messages you receive is on average one per day.
The fee for each SMS received ranges from $ 0.01 to $ 0.04.
It is also possible to use the App with two telephone numbers (useful if you have a smartphone with two SIMs) earning about double.
Once registered you will receive a $ 0.5 bonus.
