How can you possibly get caught out, as long as you turn the 2nd sim card off. Just make that part of your post punting ritual... write down your notes for a future review, have a beer and turn off the 2nd sim card.
Yes, don't get that ⬆️ bit wrong. Imagine the pain and how quick that beer turns to piss when she comes storming in shouting "who the fuck is this bitch!" 🤣
I do have a Samsung. And it is dual sim. I bought it exactly for the reasons stated and I was sick of carrying two phone's. Nobody is perfect and when you have a busy life you WILL make mistakes and that's how people are caught. You WILL forget to turn your second sim off. What if a SP wants to contact you to make arrangements but you've switched that sim off thinking they're not going to reply?
And you WILL end up calling service providers with your 'family sim' which is what I kept doing. I am single yet still keep everything separate from punting. The risk is too high especially if a bipolar bitch gets hold of your family number or some drug crazed pimp.
Not sure why you think a second Google account has to be INSTEAD of dual sim. You can and should do both.
My Google punting account contacts can still appear amongst my family contacts. There is no real risk free option other than total separation including phone. And at least you can say its somebody else's phone when you are asked to unlock it. You're also fucked if you have a tech savvy wife.
Yes, the punting phone has to have its own separate Google account.
