Mobile Network Privacy

Distinguish what Wi-Fi operators, mobile carriers, DNS resolvers, VPN providers and websites can observe.

Core ideas

Use these points to build an accurate technical model before changing the device.

• HTTPS protects content in transit but not every connection metadata field.
• A VPN shifts trust to the VPN provider; it does not make activity anonymous by itself.
• Private DNS can protect DNS transport without replacing application security.

Decision rule

Choose network tools according to a specific threat model rather than a generic “maximum privacy” label.

Apply it on your phone

Record the device facts, source and expected result. Make one reversible change, observe the outcome, and keep the evidence needed to undo it.
