Point 1: I used to have a severe case of Smartphone Envy, that was until I became the proud owner of a Blackberry Storm. The iPhone wasn't an option, because I'm pretty sold on Verizon [VZW] (mainly due to In-network calling, because the majority of my family uses VZW. Not to mention, they have great coverage). When I upgraded to the Storm, I also ported our home number from a VOIP line to VZW's Add-a-line, because I was not ready to surrender the number, and it is less than $10/mo. to keep the number active (I also got a 2nd Storm with a BOGO deal).
Point 2: I've been a GrandCentral user for a couple of years (prior to the Google Acquisition). GC is now Google Voice [GV]. I had not made use of many of their features, but we want to eventually replace our home number with the GV number. Now, the additional phone has been set to forward to our GV number, which then rings both of our mobile phones. In addition, this lets us put some filters on the numbers to limit spam, and the voicemail transcription has been pretty cool.
Point 3: VZW has added a new Friends & Family option that permits me to add 10 numbers for unlimited calling to our current Family Share Plan. At this point, our GV number is one of those numbers. I can now call my GV number (initially for voicemail purposes) without concern of minutes used.
Point 4: The loophole is that GV permits me to make an additional call from within the GV menu. The call would appear for all VZW's intents and purposes, as a call to my GV number, and therefore free of charge. This requires a little bit of extra effort, but if I know it will be a long call, it could be worth it.
Point 5: GVDialer takes all the work out of it for me. After installing GVDialer, when I select a contact from my address book or punch in a number to dial, I am given an option to call via GVDialer. It is one-touch dialing from there, the app does the rest to connect my call. I've only made a few calls using the app, but I am pleased thusfar.
This has the potential to totally revolutionize my voice communications. I'm stoked.
