However, cutting back voice service is clearly not for everyone. If, when you're on the go, you regularly rely on your phone for important calls--from your colleagues, your family, and such--that you simply cannot afford to drop, this probably isn't the plan for you. I'll probably switch over to this T-Mobile plan (or give Republic Wireless a shot), but I'm a little worried about how it will work when I'm covering a trade show such as CES, where mobile broadband connections are unreliable at best--and nonexistent at worst.
Going VoIP-only isn't a perfect alternative yet, but for the right kind of smartphone user, it's a viable way to slash your cellular bill in exchange for the occasional minor inconvenience. The writing is on the wall: Smart tech consumers won't put up with pricey unlimited-everything plans for much longer.
