How to register as an economically self-sufficient resident in Malta

Thanks a lot for your answer.

This is my list of maltese health insurance companies :

https://www.bonniciinsurance.com

https://www.bupa.com.mt

I haven’t asked a quote yet from them but I’ll do soon.
If you have any advises about them, please tell me.
Do you live in Malta ? I’m actually in Gozo.
See you
