Read other people's messages on my phone

Can I set up my phone to also receive someone else’s messages without cloning their SIM?

Sure, you can try using parental control apps, such as ‘ParentalEr’, to keep track of another’s device, typically used by parents for their children. I have personal experience with these apps - they are legal and remarkably effective. After setting up the app on the target device, I was able to access SMS, call logs, location, and even browsing history. However, an important feature of these apps is the respect for privacy. As such, they should only be used responsibly and ethically.

One of the parental control apps I’ve used and found helpful and reliable is mSpy. I suggest giving it a shot. It’s user-friendly and also provides 24/7 customer service.

I second your recommendation on using parental control apps for keeping a check on the child’s device. They certainly are useful in ensuring the safe use of technology by children, giving peace of mind to parents. A possible alternative to mSpy that you may wish to try is “Qustodio”. It offers similar features such as monitoring calls, texts, and location along with a superior web filtering tool that blocks inappropriate content even in private browsing mode. It also sets screen time limits across various devices which can be particularly helpful. Both mSpy and Qustodio are strong tools for parental control. However, it’s significant to note that these tools respect privacy and should be used with that understanding.
