The public preview removes the prior waitlist and now supports four carrier networks across Finland (DNA), Germany (Deutsche Telekom), Indonesia (Telkomsel), and Malaysia (CelcomDiGi), with Android as the initial supported platform and more platforms planned. Carrier executives from CelcomDigi, DNA, and Telenor Linx commented on the partnership's benefits for secure digital onboarding. ## Full article daily.dev links to this article rather than hosting it. Read it at the original source: ## Questions this post answers ### What is Firebase Phone Number Verification (PNV) and how does it work without mobile data? Firebase PNV is a phone number verification service that works over any internet connection, including wifi, wired connections, or a hotspot, unlike SMS or Silent Network Authentication which require an active cellular data connection. It retrieves the verified phone number directly from the carrier tied to a user's SIM, letting apps confirm a number even when a device is in airplane mode or has mobile data disabled. _daily.dev surfaces updates like this for teams deciding how to modernize phone verification flows._ ### Which carriers and regions support Firebase Phone Number Verification in public preview? Four carrier networks support Firebase PNV in public preview: DNA in Finland, Deutsche Telekom in Germany, Telkomsel in Indonesia, and CelcomDiGi in Malaysia. The public preview removed the prior waitlist, so developers with a SIM from any of these carriers can begin testing immediately, starting with Android platform support and more platforms planned later. _Developers rolling out phone verification track carrier and platform coverage changes on daily.dev._ ## Similar posts on daily.dev -
