https://silent.link does not meet my privacy requirements as the service requires me to have a physical phone. I dislike this. Phones leak geographical location as operators know which LTE/5G cell it is connected to.
Eternad: to be frank your request to be paid the full .002 BTC upfront raises a red flag to me. I am offering to pay half (.001 BTC) upfront. I stand to lose all that if you scam me. But with my offer, no matter what, you get paid at least .001 BTC. Then if I were to abandon our deal, you would have spent $5 on the SIM for the first month, but then you can cancel it. You'd still be making a profit well over $60. I don't understand your motivation to insist to be paid the full .002 BTC upfront, unless you think $60 isn't enough profit to make it worth your while.
