Over here, mobile usage is still priced very high, whereas landlines typically are just a flat monthly rate for local calls, so the latter is often preferred, especially for long distance and/or long duration calls.

But many of us have long since ditched the traditional land-line circuits, in favour of Voip adapters (ATAs) plugged into our broadband internet connections. I pay about $1.50/month for an inbound number (DID) with every calling feature imaginable (including voicemail), and $0.01/minute to use it for calls anywhere to/from USA/Canada. And somewhat more (but still cheap) for the rest of the planet.

Cheers
