SIM Card Info is a free utility app for Android developed by predefault. It displays information about your SIM card, including the IMEI code and the contacts saved on it. However, it's important to note that some devices may not provide their own telephone number. The app also allows you to long-press on parameter text to copy it to the clipboard.

The app supports the following features:

• SIM card information
• Device information
• Contacts stored on SIM card

Overall, SIM Card Info is a useful app for obtaining SIM card information and contacts stored on it. The app is easy to use, and the information provided is accurate. However, it would be better if the app also supported the ability to edit or delete the SIM card contacts directly from the app.
