Your instincts are spot on. VPNs can indeed bypass many of the age restrictions imposed by mobile network providers, and the Online Safety Act has inadvertently made this loophole more visible.
How VPNs Bypass Age Restrictions
Network-level filters (like those set by mobile providers) rely on detecting and blocking traffic based on IP addresses and DNS requests.
A VPN encrypts all internet traffic and routes it through a remote server, often in another country. This hides the user's real IP address and makes it appear as though they're browsing from a different location.
As a result, the mobile provider can’t see or filter the content being accessed, effectively nullifying its age restrictions.
The Online Safety Act & VPN Surge
Since the Online Safety Act came into force on 25 July 2025, there’s been a massive spike in VPN usage across the UK:
VPN sign-ups surged by over 1,400% in the hours following the law’s enforcement.
Many platforms now require ID scans, facial recognition, or credit card checks to verify age.
Teens, being digital natives, are increasingly savvy at finding workarounds—VPNs being one of the easiest and most effective.
What This Means for Parents
Default mobile restrictions are a good start, but they’re not foolproof if a VPN is installed.
Many free VPNs are readily available on app stores, and some don’t require any technical know-how to use.
Once connected, your child could potentially access adult content, social platforms with age gates, or even bypass parental controls.
What You Can Do
Check for VPN apps on your child’s device (look for names like ProtonVPN, NordVPN, Surfshark, etc.).
Use router-level parental controls or app store restrictions to prevent VPN downloads.
Consider regular conversations about online safety—not just rules, but why they matter.
Some experts suggest combining technical safeguards with digital literacy, helping kids understand risks rather than just blocking access.
Hope this helps
