Comodo Backup simultaneously backs up all of your contacts from the device's SIM card and memory in just a few simple steps. Before creating a backup file, Comodo scans your device to find all the texts and contacts that are stored on the SIM card and in the system's memory. You will need to have the Comodo app installed to restore your contacts from this backup file, since it cannot be accessed with other apps. You can also use Comodo to back up any texts that are stored on your device. Comodo is compatible with Android versions 4.0 and higher.
