Hi! I understand your concern about wanting to trace a SIM card to see who is messaging the phone. Unfortunately, without access to the phone itself or the ability to install tracking or monitoring software, it can be difficult to trace the specific messages being sent to the phone.
If the phone your father is using is not a smartphone and does not have any tracking or monitoring apps installed, it may be challenging to trace the messages in real-time. One possible solution is to contact the mobile network provider and ask if they can assist in providing call logs or message history for the SIM card in question.
It's important to note that tracking someone's phone or monitoring their messages without their consent may raise legal and ethical concerns, so it's crucial to handle the situation with care and respect for privacy.
If you have specific concerns about the messages being received on the phone, you may want to consider having an open conversation with your father about your worries and discuss potential solutions together. Communication and trust are key in resolving issues like this within a family.
If you have any more details or questions, feel free to share them so I can provide more tailored assistance.
