Mobile Network Operator Application
Mobile network operators offer different data plans to Android users, and tell the ways how they can keep a record of it. For example, in the United States the network carrier Verizon offers an application called My Verizon. Once installed, this application helps to monitor your Android data while it is used. Similarly, AT&T has myAT&T application, which performs a similar function. Operators in other countries have applications of their own, which can be downloaded from their websites or through free sources and used.

3G (3rd Generation) Watchdog
It is an open source application, available for download from third-party developers. Once installed, it tracks down data in raw form from your mobile and then calculate it use. You will also need to set your data limit, alerts and billing cycles. The alerts keep you aware about the data use, by updating you in form of table. It is one of the most effective data monitor application.

My Data Manager Application
My data manager is also a third-party application, free to download and use. Just like 3G Watchdog, it collects data from all sources available on your Android phone and notifies you about the use in statistical form. This can also help you know which applications are data hogs.
Once you installed My Data Manager on your phone, put in details of your data plan. You can set alerts at a frequency you want to be notified about the data usage.
