Guides / VPN on mobile data — cellular tips for 4U
Using 4U VPN on mobile data
A VPN works on cellular as well as Wi‑Fi. Many people keep the tunnel on LTE/5G when a café hotspot looks untrustworthy — or when hotel Wi‑Fi blocks VPN protocols.
When cellular is the better path
- Public Wi‑Fi feels suspicious or keeps failing captive login
- Hotel networks block or throttle VPN
- You need a quick private session while walking or in transit
Things to watch
VPN traffic counts against your carrier data plan. On roaming, costs can rise quickly — check your operator rules before leaving long sessions on.
Battery use can increase while the tunnel stays up; disconnect when you do not need it. The free session timer still applies on cellular the same as on Wi‑Fi.
Setup reminder
Install 4U from the official stores, allow VPN permission once, connect, then open your apps. No account is required for the free timed session.
Carrier policies and roaming fees are outside 4U’s control. Monitor your data usage in system settings.
