It's easy with mSpy. After you pay for your text tracking subscription, you’ll receive an email in your inbox with detailed instructions to get you up and running. The instructions are tailored for the type of device they own — right down to whether it’s jailbroken/rooted or out of the box. Just follow the instructions and after everything syncs for the first time, you’ll have all their texts at your disposal. Simply sign in to your mSpy Control Panel whenever you like to review their text messages.
