Dual Sim iPhone with T-Mobile

So I switched to T-Mobile from Sprint and love how fast T-Mobile is. The only bummer is that there are a few places I go that T-Mobile doesn't have great coverage. I don't go there too often, but my job takes me here and there. So, I bought a Magic-Sim dual sim adapter for my iPhone 5 and use a pre-paid AT&T Go Phone $2 a day unlimited plan and I can switch carriers whenever I need to.

On long car trips sometimes we'll need to switch if T-Mobile doesn't roam well there.

So the question for my wife and I was pretty simple. Switch to T-Mobile and Spend $75 a month after employee discount or stay with Sprint, AT&T or Verizon and pay at least $140 for the family plan. That's a savings of $780 a year. So...for $780 a year, would you deal with a bit of inconvenience to switch sims for the few times you need to?

 

Here's the website that I bought the dual sim adapter from.

It shipped from England and took a few days to get here. I wrapped the ribbon cable around the back of my iphone and then cut a hole in the otterbox case for the iPhone 5 to make it sit flush behind the case. Now I can switch between ATT and T-Mobile with the push of a button and I love it. I only pay $2 a day on the days I actually use the phone so it's cheap insurance to make sure I can make a call when I need to if T-Mobile doesn't work. So far, I've used it twice in two months.

Plus...why would I want to carry another phone when I can make my iPhone act like two phones, or three if you count that I use Google Voice too.
