Are you recommending I change Preferred network type " to 3G? other options are 4G only 5G ( recommend ) 4G if I use that DNS with what VPN u recommend, and have allow 2g disable am I good?

I have a sim card in this phone. The sim card is one I heavily rely on. I have disabled the option for disable 2G in sims is this good? Even without the LTE mode as my phone doesn’t seem to have this.

I don’t have any crypto / XMR and in this case, shall I just set the DNS you recommended me without any VPN and just always use that? Thanks.

I have already inserted a sim card into this phone. The sim card is a kyc sim card. I want to do best I can without compromising my identity. My threat model does involve government interception and tracing, but it’s more about staying Safe with this phone whilst I’m possibly under surveillance. Local police entities. More so than government contractors / third parties. What is best VPN to use in this phone? I rely in the sim card in this phone so always keeping in aeroplane mode isn’t possible as this is my primary number and I need to have constant connection to it. In this case, what shall I do with this phone?
