That's a PS5 you didn't spend on verification. Every month.
Twilio Verify lists $0.05 per successful verification, before channel fees. Contiguity doesn't charge for the OTP API – you only pay for the text, from your existing quota or Unlimited plan.

Cost Savings
Contiguity doesn't bill you for receiving ROTPs, and you don't have to lease a number to receive them. It's the cheapest way to verify a phone number.
Better Delivery
Since users message you, delivery is much higher – especially internationally, where sending to the US is almost always included.
More Secure
Receiving SMS is cheap, while sending SMS is expensive. Stop most fraudsters using fake phone numbers in their tracks.
