It is possible to retrieve deleted text messages from an iPhone or an Android smartphone. There are multiple methods that typically rely on the use of a cloud server or a computer-based software program.
For iPhone devices, deleted text messages can be recovered from the iCloud server if the phone data was previously backed up. Alternatively, the deleted text messages can be retrieved through iTunes, but this method also replaces all existing data on the phone. Android smartphone users do not have to erase their current data, but the process is slightly more challenging because it often requires root access and a paid third-party application.
