7) Switch to another server or region
Pick a nearby low-load server in the app. Test at least three different locations.

In the app, switch protocols. Try WireGuard, IKEv2, or OpenVPN TCP 443 for restricted networks.
9) Test Wi-Fi vs cellular

15) Contact support or try a different provider
Ask your VPN support for iOS specific guidance or manual configs. If issues persist, test a reputable iPhone ready VPN with multiple protocols and obfuscation.
For users who need seamless cross-device protection, it’s worth checking the best VPNs for Mac and iPhone since providers that maintain strong iOS apps also tend to deliver reliable Mac compatibility.
