It seems this used to be possible possible with dual band handsets if UMA was allowed by the mobile service provider. Is there a similar way now?
My situation is no mobile coverage at home, but have very good wireless broadband and home wifi network. I'd like to get a mobile handset that will use a specific provider's network when I'm out and about but will automatically switch to using my wifi network when home.
This is different to wanting to use VOIP. Makes sense? Any ideas?
