Does anyone know how to receive text messages from another phone?

My kid has been acting weird with their phone lately and I want to check their texts on mine to make sure everything’s okay. I’ve tried a couple basic ideas but nothing works without them noticing. Any suggestions on how to set this up?

Julie, I’ve been in your shoes before. You can use built-in features like iCloud or Google Drive backups to monitor messages, but it’s not the most reliable method. If you want a straightforward solution, I’d recommend checking out mSpy - it’s a solid tool for keeping an eye on your kid’s phone activity without them noticing.
