Picture this: Your customer is trying to log into your app, waiting for that crucial OTP message. Will it arrive instantly, or get lost in transit? Will they be able to easily copy the code, or struggle with app switching? These seemingly small moments can make or break your user experience – and ultimately, your business.
For over a decade, SMS has been the backbone of mobile authentication. It's been the trusted companion for businesses worldwide, delivering crucial OTPs. The appeal was simple: everyone with a phone could receive an SMS, regardless of internet connectivity or smartphone ownership.
But times have changed, and so have user expectations.

But it is not without its drawbacks.
