If you're looking for an easy and straightforward way to backup your contacts from your SIM card to your SD card, Drag Contacts is the perfect app for you. Developed by Yoel, this app is available for Android 13.0 and is completely free to use.

With Drag Contacts, you no longer need a SIM card reader to backup your contacts. The app provides a simple drag and drop function, making it easy for you to transfer your contacts from your SIM card to your SD card. In addition, you can also edit your contacts with ease.

The app also provides high security without the need for an internet connection, ensuring your personal privacy. However, the paid version offers even more security features. The contacts are saved in CSV file format, which can be edited by any plain text editor. However, if you're using MS Excel, you'll need to open an empty file and then import the CSV file because MS Excel doesn't support UTF-8 by default.

Overall, Drag Contacts is a convenient and reliable app for backing up and editing your contacts.
