This has not been incorporated yet through hardware and may not ever be but iPhone users can enjoy the dual mode experience through Line2. Designed for professionals who cannot afford to miss a call, Line2 combines the best elements of Skype and Google Voice, but adds business grade features, reliability and even live customer support. All these, from an application.
So how does it work? It’s amazing right? How an app for an iPhone can do this. The logic is pretty simple. Line2 adds a second number to your iPhone that works over WiFi, 3G, or Cellular networks using the same number which is an industry first. It is the ideal solution if you have poor cell reception or just want to reduce your bill.
Download the Line2 app and pick a new local or 800 number or port your existing number for free. With unlimited US/Canada VoIP on iPhone calls, low international rates, call waiting and call transfer features, 6 number simulring, auto attendant, up to 20 person conferencing, visual voicemail and many more, this app gives you more than how much it costs.
Oh wait! The good news is it is free! No Cell Reception? No Problem! Line2 is the only app that lets you have 2 phone numbers on iPhone and lets you call over WiFi, 3G and cell. You can check for more information of Line2 at iPhone app reviews.
