If you live in an area with spotty carrier reception, it’s still possible to make regular calls over WiFi thanks to the power of VOIP. But there are so many apps out there, which require the person answering the call to have the same app as well. What if you wanted to call someone just by using their phone number? This is where SIPdroid stands out. When SIPdroid is activated, it uses your regular dialer and contact list just like when you’re making a call on EDGE or 3G. It might take a bit of work to set up, but you’ll only need to do it once, but it’ll be worth all the free calls you can make over WiFi for the rest of your life. Head over to the Droid Guy for details on how to setup SIPdroid for your phone. Once you do, let us know how it works out for you.
