A free program for Android, by Keshigoto.

In the past few years, the number of smartphone users has been increasing rapidly, and with it, the amount of data being used has also been increasing. In order to cope with this, the U.S. wireless industry has been implementing new standards, such as the WCDMA and LTE, which can handle more data. However, these standards have increased costs, and they don’t support all phones. As a result, even though the market is moving to the new standard, some older phones cannot be upgraded to WCDMA or LTE. This is where EventSound comes in. It is a simple application that allows you to use your smartphone as a WCDMA or LTE phone. You can use it on any Android phone that has WCDMA or LTE support.

You can also use it to detect when your phone is on or off. It detects the start and end of each hour and can also detect the start and end of each day.
