Yes. A VPN works over kimsim data like it does over Wi-Fi.
Local law still applies. Some countries limit how VPNs may be used: in the United Arab Emirates, for example, misusing one can bring a heavy fine. Check the rules for where you're going. UAE rules for calls and VPNs.
When something's wrong
A VPN can slow things down, and it can make it look like data isn't working when the VPN itself is stuck. When you're troubleshooting:
- Turn the VPN off.
- Check data works without it.
- Then switch it back on.
Apps think you're somewhere else?
A VPN shows apps the location of its server, not yours, so switch it off and check again. Why apps think you are in another country.
