Safari says my iphone is not connected to the internet.

Connecting to Wifi is the first part and then getting connected to the Internet is the second

1. If you connect to Wifi, doesn't necessarily mean you are connected to the internet. If you are not connected to wifi could be a problem with iPhone settings or Router/Modem Settings
2. If you are not connected to the internet is the sole issue of Router / Modem Settings. Contact your ISP immediately

For your Internet connection.

• Over Cellular: contact your Carrier (Cellular Service Provider). The agency who issued the SIM to you
• Over WiFI: Contact your ISP (Internet Service Provider), the agency who provided the Internet Service on your Modem/Router to you

However --> Connect iPhone to the Internet - Apple Support

When you are not near your home or office the only Internet connection your phone has is cellular data. So you must go to Settings/Cellular and make sure it is ON, and then scroll down to Safari and also make sure the data switch for Safari is ON.

Also, if you are using a VPN connection (if you open the Control Center it will say “VPN” in the top status bar) try turning it off; the switch is in Settings/General near the bottom of the list of settings. Many VPN services don’t work over cellular data. And there is no good reason to use VPN except to connect to an office network.
