Never was able to get a OTP to my Quo (OpenPhone) number. I don't know how this has such high ratings. It's overpriced AND doesn't work! More expensive than competitors. I switched to Slynumber and was instantly able to get authorization codes and use it for US banks even. Slynumber is 1/6 the cost if you get the yearly plan. Quo also has no customer service. BOO.
