Earlier quoted context omitted.
One issue I can forsee: - Every contractor (plumber etc) you hire will ask you to please add them to your contact list first so that they can message you. - After a while of half their clients not doing that and lots of fees on their end, contractors stop providing a phone number at all, asking you to please install ContractorApp to communicate with them.
Maybe when you first receive a text you see: This message is from an unknown number. (Accept / Block / Charge sender $1)
I disagree about the we-adda-baby-itsa-boy issue. I don't see how that'd apply given that you can charge them $1 from the very first message.
