How to make a TCP tunnel on IOS?

Question

iOS

Hello!)
Used to be an Android user. I used the anonytun program, which allowed me to bypass restrictions on the mobile Internet.
In fact, this is a VPN only configured through a tunnel. (I'm not special in the question, I can make mistakes in the expressions: C)
Now I switched to IOS and did not find an analogue of this application, but as far as I understood, this program simply changes the settings of the VPN file that can be opened in openvpn, which is on IOS.
Here are screenshots and Headers from the program for Android:

POST http://mobile.twitter.com HTTP/1.1[crlf]
Host: mobile.twitter.com[crlf]
Connection: keep-alive[crlf]
User-Agent: [ua][crlf]
[crlf]

Is it possible to somehow apply these settings to a vpn file from tcpvpn.com, run it on IOS and bypass Internet restrictions?
