The How Many Sim in My ID? app, developed by AndLication, is a free utility tool available for Android devices. As the name suggests, the app helps you find out how many SIM cards are registered with your ID number. This can be especially useful if you have multiple SIM cards or if you're unsure about the number of SIM cards registered with your ID.

The app is straightforward and easy to use. Once you enter your ID number, the app quickly displays the number of SIM cards registered under it. The app also provides details of the telecom operator and the state where the SIM cards are registered. The user interface is simple and user-friendly, making it easy for anyone to use.
