The iPad is great at a lot of things…but distinct its iPhone sibling, it can’t make or receive phone calls. Line2 intends to solve that dilemma and is now offering its app for the iPad and iPhone, making it the only calling app available for the iPad that works over WiFi and 3G.
When you sign up for an account with Line2, the company offers you with a phone number. You can then make and receive phone calls from the app. Line2 will use your 3G data plan to broadcast data under normal circumstances, but if you’re within range of a WiFi network, the app will automatically switch to WiFi—even in mid-call.
All this comes at a price, though; similar to any good service, Line2 has a price tag, in this case, it’s $14.95/month. If you’re appearing for a WiFi/3G VoIP app for the iPad, though, the lack of competition makes that cost a good investment.
