When looking for the best unlimited data plan for teenagers, parents often worry about safety and excessive mobile use. With most standard mobile networks, parents can turn off WiFi at night, only to find their teen switching to mobile data and staying online.
That’s where ParentShield’s Unlimited Data Plan is different. It allows teenagers to have an unlimited data plan – but with powerful parental controls that put you in charge.

The Only Unlimited Data SIM Designed for Parents
Unlike standard unlimited SIM-only deals, which focus purely on data limits, ParentShield’s SIM offers complete control over mobile data, calls, and texts.
With ParentShield’s Unlimited SIM, parents can:
- Turn data on or off remotely – Instantly disable mobile data via the ParentShield portal.
- Set time controls – Automatically cut off internet access at bedtime, during school hours, or at any time you choose.
