I use signal for all my communications with my friends and family. SimpleX with people I don't know that well. Google voice number for spam trap. My actual phone number i don't use for anything. I have it set to silent and never look at it.
I used to stress out and try to juggle numbers and communication paths for normies and then one day I had enough. I let everyone know that if you want to contact me then you have to go through signal. That I will not be checking any other numbers and you will not get a response from me.
Most people were surprisingly adaptive
