Hello, never really understood this mining with old phones thing.... so what I don't get is that you have these old smartphones that you are NOT using correct? So they are NOT in service by your ISP (At&t, Verizon, ect..) so how do you download and run the mining software on a phone that is not in service? I always loved this idea but figure you need cell service on the phones your using. So it would only work using a friends or you'd be paying cell service every month for a old phone you only use to mine and nothing else. Thanks. hope to hear back soon! Would love to start this!
