What happened
U Mobile introduced SIM-based Phone Number Verification on its ULTRA5G network with Telenor Linx, letting apps verify a user's mobile number directly through the carrier network instead of SMS OTP. It is available to developers using Google Firebase and targets account registration, login, and mobile-number verification, with U Mobile citing SMS OTP's lack of encryption and phishing/interception risk as the problem.
Why it matters
If you build phone sign-up or login for a Malaysian app or SaaS, this is a potential way to reduce SMS OTP cost and fraud, but the text gives no pricing, coverage beyond U Mobile numbers, or concrete Firebase integration steps. Treat it as a reason to ask U Mobile/Telenor Linx for API docs and fallback rules before replacing your existing OTP flow.
Discussion angle
Would you switch a Malaysian app from SMS OTP to SIM-based PNV if it only covers U Mobile subscribers, and what fallback or consent flow would you need for everyone else?
