A lot of people have written in [wondering how my move to Verizon went](http://brooksreview.net/2012/09/vz-att/): It was the easiest thing in the world. ((That’s probably an exaggeration.))
To follow up:
– I haven’t noticed the lack of simultaneous data, as I figured I would rarely notice it.
– I have yet to not have LTE coverage in the areas I have roamed around in.
– The family plan thing was a piece of cake.
Here’s how I made the switch: I ordered the phone on Apple’s website, told the Apple website I wanted to port my AT&T number to a Verizon phone. The Verizon phone showed up, I set it up and within a minute my AT&T iPhone was not active and my number was on Verizon. I was the primary account holder on the AT&T family plan, no problems with that, as AT&T just moved another line to the primary spot.
The only word of warning I would give, something I didn’t think about, is that you lose your voicemails. I had to setup the Verizon voicemail, so it was a little unnerving to lose my other ones — but not a big deal. (You also have to re-record your voicemail greeting — I mean what a *pain*.)
That’s it, fast and painless.
