My overall experience with Krispcall(bad and good)
I've been using Kriscall for over 6 months now, and here are my good and bad experience with Krispcall. Good: Really affordable pricing. I'm using 10 plus more US virtual numbers. Also, low credit charges for calling and SMS. They have pretty cheap pricing for both. Bad: Krispcall App can be unreliable. Sometimes, sending SMS not working at all. I think they are more focus on web version. However, support is helpful in addressing issues in realtime.
