Why this matters:How to recognise this workaround on your side, and what closes it on your side — without telling you how to do the workaround.
How common it is: Dual SIM and eSIM are documented device capabilities on current hardware. Specific use as a parental-control circumvention technique among minors is not established.
Detection
The device shows two cellular lines in its status indicators; cellular-data use is high while the home Wi-Fi is idle; the device’s carrier settings expose two carriers.
Fix (technical)
Where the device’s parental-control system can lock the cellular-data path, apply the rule to both lines. Where the carrier offers a content filter, enable it for each line. Do not assume one carrier’s filter covers the other.
Fix (relational)
Two lines is not in itself a finding. A child with a school-issued data line or a family travel line has a legitimate reason. Address the rule’s coverage across both lines rather than the line count.
Residual risk
Locking both lines does not reach a peer-shared hotspot on a third operator. The cellular path remains the load-bearing gap for any carrier-side filter.
