I have tried the EAP SIM option it does not connect.

Tried from the forum some options, however the Do Not Validate option is not available and it asks for a Domain to get through. I have tried connecting using other devices with same username and password it works perfectly. Can anyone help here?

Eap-Method : TTLS (for some it works with PEAP instead of
TTLS) Verification Phase 2 MSCHAPV2
CA certificate --->Do not validate option is not available on Google Pixel Devices
