How can I ditch my carrier and just use Wi-Fi?

When Steve Jobs unveiled the first iPhone in 2007, he famously teased it as "three devices": An iPod, a phone and an "internet communications device" — maybe the clunkiest three words ever uttered at an Apple keynote.

On this week's episode of Too Embarrassed to Ask, Recode's Kara Swisher and The Verge's Lauren Goode question whether your smartphone can be just an internet communications device. Can you stop paying for AT&T, Verizon, Sprint or T-Mobile and only use Wi-Fi to do all your talking and texting?

That raises the question, of course: What if you're somewhere without Wi-Fi? Kara and Lauren are joined this week by Steven van Wel, the CEO of Karma, which makes a portable hotspot called KarmaGo. Technically, the device is turning Sprint's cellular data signal into a Wi-Fi network, but van Wel said the whole point is not having to think about where your data is coming from or how much you're using.

And he should know -- his iPhone spent four years without ever leaving airplane mode.
