Hi Ravi - I spent 5 years at Twilio and am currently over at Messagebird (CPaaS).

• Generally, there are two options:
• use SMS API and own the logic on your side (Phone number provisioning, token creation, token validation, retries, fallback etc.)
• Verify Solution (which both Messagebird and Twilio offer): Verify provides a purpose-built API. Number provisioning (especially challenging globally), token creation, retries, fallback methods, etc. are managed by the verify solution

Messagebird helps the largest senders with use cases like OTP globally, and you have the choice own the development, or use the Verify API. Anecdotally, our Global network, and the maturity of our network, makes us stand apart in regards to global reach and deliverability.
