I use fongo to receive texts from already screened clients. It's very obvious my number is not a standard toronto area code and number. I have had problems occaisionally receiving text messages from clients, sometimes the push notification doesn't go through right away and has showed up hours later or the next day. I absolutely do not use it for phone calls, anytime I've had someone call me the cell quality was bad and it seems to lag between ringing and pick up, so sometimes they've hung up while I'm still seeing it ringing. This happened twice when clients were having text problems and tried to call me instead, as I don't just accept random text messages or calls at all these days.
I simply don't have a seperate work number as I need my smart phone for work not a burner and don't want to risk some troll finding out my name because they have a buddy that works as a PI or for the phone company. Stuff like that happens unfortunately, some girls I know even were outed cuz a client ran their license plate. I don't accept text apps and don't recommend any provider accept them unless they already know the client or thoroughly screen them, there's just no way to know someone isn't fake booking you or a previously blacklistted guy when they book anonymously with a text app and most no show/cancel last minute honestly because there's no respect.
