Someone correct me if I'm wrong, but aren't text messages, photos, call numbers, etc. store on the hard drive of your phone or computer, and have nothing to do with your service provider. I'm just asking. ty
Sort of. As I understand it, the service provider transmits your text to your phone and it disappears from their server.
The info is then on your phone in the RAM (Random Access Memory) which is different than the hard drive on a computer. Depending on your settings and type of phone, it might be backed up somewhere else. For example, if you have an Android, your photos might be backed up on Google Photos.
But ... if you delete a text message, and that part of your RAM is written over, its gone from your phone but might be backed up somewhere else.
