oFono, a critical component in #SailfishOS, acts as the bridge between the OS and the cellular modem. It ensures seamless access to cellular services for apps.
@piggz, a very dedicated member of the Sailfish OS community has created a blog series to enhance oFono for Sailfish OS.
I've only read two days of @piggz's #ofono blog - he's upstreaming #SailfishOS changes to ofono to make future downstream updates easier - and I'm already looking forward to Day 3!
