How to Choose the Right Mobile Service for Your Business 3G or 4G? WiMax, LTE or HSPA+? With so many options in the smartphone market, it's hard to know which is the best device on the best network at the best price.

Q: How do I know if I'm buying the right mobile service for my business?

A: It's one thing to make a bad technology-buying decision. It's quite another to make one that you have to relive--and pay for--month after month. That's essentially what's at stake when buying mobile devices and services these days, thanks to the countless, complex options facing business users--not to mention the dreaded two-year service contract that keeps you locked into a bad decision to the tune of more than $3,000 over its lifetime.
