The test token uses the same methods as production, so switching to production only requires removing one line of code. Firebase is also expanding its list of supported carriers, and positions PNV as a third-generation verification method (after SMS and Silent Network Authentication) that works even in airplane mode, requiring only an internet connection. ## Full article daily.dev links to this article rather than hosting it. Read it at the original source: ## Questions this post answers ### How do I test Firebase Phone Number Verification without a credit card or live SIM? Firebase Phone Number Verification (PNV) now offers a SIM-less test mode that requires no billing setup, no supported SIM, and no production onboarding. It takes about 1 minute from project creation to generating a test token, and the test token uses the same methods as production, so removing one line of code moves the app straight to production. _daily.dev surfaces release notes like this for developers evaluating phone verification options before committing._ ### What is Firebase Phone Number Verification and how is it different from SMS OTP? Firebase Phone Number Verification (PNV) is a third-generation phone verification method following SMS and Silent Network Authentication, now generally available. Unlike SMS OTP, it can verify a phone number even when the device is in airplane mode or has mobile data disabled, as long as the device has any internet connection, and requires only one tap with informed user consent. _Developers weighing SMS OTP against newer verification methods can track updates like this on daily.dev._ ## Similar posts on daily.dev -
