ICCID is a free Android application developed by oliaNet that allows users to quickly and easily retrieve the Integrated Circuit Card Identifier (ICCID) of their SIM card without having to physically remove it. This unique identifier is required when transferring phone numbers from one operator to another. The application also displays information about the mobile network operator of the SIM card.

This utility tool is especially useful for dual SIM phones running on Android 5.1 or later, as it supports both SIM cards. By using the ICCID application, users can save time and avoid the hassle of pulling out their SIM card to retrieve the ICCID number.
