Random guys texting my 13yo. Parental control app to block numbers that auto-blocks any contact not in my approved list?

Hello, for this purpose, I recommend exploring uMobix. It’s a comprehensive tool designed for parental oversight. While its core strength is monitoring, it includes features to manage calls and contacts effectively.

You can view all incoming/outgoing calls and text messages, even those that have been deleted. This allows you to see who is contacting your child. For direct blocking, you can use its features to restrict unwanted contacts. Its interface is user-friendly, providing detailed logs of messages from various platforms like WhatsApp and Messenger, ensuring you have a full overview of your child’s communications. This helps you proactively identify and block any suspicious numbers.

Sorry you’re dealing with this. Fast ways to allow-only contacts:

  • iPhone: Settings > Screen Time > Communication Limits > set Contacts Only for Allowed time and Downtime; Settings > Phone > Silence Unknown Callers; Messages > Filter Unknown Senders.

  • Android: Phone app > Settings > Blocked numbers > enable Unknown/Private; enable Caller ID & spam protection; Do Not Disturb > Allow calls from Contacts only or Starred only. On Pixels/Samsung, Call Screen/Smart Call can auto-block suspected spam.

  • Carrier-level: Verizon Smart Family, AT&T Secure Family, and T‑Mobile FamilyMode let you block specific numbers and sometimes unknown/private across the line.

For deeper oversight, mSpy also alerts on new contacts, flags risky keywords, and shows message/call logs, helping you quickly add safe contacts and act on anything suspicious.

Which phone?

iPhone (best for this):

  • Settings > Screen Time > Set Up as Parent.
  • Communication Limits: set Allowed Communication to Contacts Only (or Specific Contacts) for both Allowed Screen Time and Downtime.
  • In Family Sharing > Manage Contacts, require parent approval for new contacts; disable “Allow Contact Editing” if shown.
  • Phone > Silence Unknown Callers: On.
  • Messages > Filter Unknown Senders: On.
  • Lock Screen Time with a passcode.

That effectively blocks calls/messages from anyone not on the approved list and hides unknown texts.

Android:

  • Install/set up Google Family Link; manage the child’s contacts and require approval for new ones.
  • Phone app > Settings > Block numbers > Block unknown/private numbers (OEM wording varies).
  • Set Do Not Disturb to allow calls from Starred contacts only; star approved contacts.
  • Google Messages > Settings > Spam protection: On; mute notifications from unknown senders.

Also review third‑party chat apps (WhatsApp, Snapchat, etc.)—use their per‑app contact/privacy settings or restrict those apps if needed.
