How to 'tether' your PC to your phone

A lawsuit now makes 'tethering' PCs and phones cheaper.

Michael Sloan

Last year, the Federal Communications Commission (FCC) investigated Verizon Wireless for stifling a very useful smart-phone trick.

While laptops often need cables or Wi-Fi networks to access the Internet, phones can log on from just about anywhere. So if you find yourself with excellent cellular reception but no Wi-Fi – such as on a road trip, in an airport, or at home during a power outage – why not connect your two devices? Let your smart phone deliver Internet access to your computer. It's called "tethering."

Until last summer, when Verizon settled with the FCC for $1.25 million, tethering was costly. Phone companies locked away the feature behind an extra monthly fee. Even if you never went over your phone's data allowance, the carriers wanted $15 to $20 a month to let you pass that data along to your PC.

Now, thanks to new monthly plans and software, tethering is much less expensive.

Verizon and AT&T revamped their data plans last summer. Both now focus on a large pool of data – anywhere from 250 megabytes to 10 gigabytes a month – that people can share across multiple devices and family members.

If you sign up for Verizon's Share Everything or AT&T's Mobile Share plans, tethering is free of charge – as long as you stick to your monthly data allotment. Most smart phones come with a built-in "mobile hotspot" feature. For example, iPhone 5 owners can find the toggle by opening "Settings" and then "Cellular." Once the hotspot is turned on, computers can connect to it as if it were a Wi-Fi network.

Sprint, T-Mobile, and older plans from Verizon and AT&T still charge about $20 a month to turn on a phone's mobile hotspot. However, because of the FCC settlement, Verizon won't charge for using third-party tethering applications. The Android app store has several good options with one-time fees, such as PdaNet ($15) and EasyTether ($10). EasyTether Lite costs nothing, but blocks secure websites and instant messengers.

Tether.com tried to release a third-party ­iPhone app to escape Verizon's extra fee. However, Apple rejected the app, as it has all tethering apps. (Apple has not publicly said why.) So the engineers at Tether found a way around Apple. They rigged up a way to tether an iPhone to a computer completely through the phone's Web browser. The service costs $30 a year and works with Apple, Android, and BlackBerry devices. You'll need to watch your monthly data usage, but Tether.com says that its service is completely aboveboard.

Dear Reader,

About a year ago, I happened upon this statement about the Monitor in the Harvard Business Review – under the charming heading of “do things that don’t interest you”:

“Many things that end up” being meaningful, writes social scientist Joseph Grenny, “have come from conference workshops, articles, or online videos that began as a chore and ended with an insight. My work in Kenya, for example, was heavily influenced by a Christian Science Monitor article I had forced myself to read 10 years earlier. Sometimes, we call things ‘boring’ simply because they lie outside the box we are currently in.”

If you were to come up with a punchline to a joke about the Monitor, that would probably be it. We’re seen as being global, fair, insightful, and perhaps a bit too earnest. We’re the bran muffin of journalism.

But you know what? We change lives. And I’m going to argue that we change lives precisely because we force open that too-small box that most human beings think they live in.

The Monitor is a peculiar little publication that’s hard for the world to figure out. We’re run by a church, but we’re not only for church members and we’re not about converting people. We’re known as being fair even as the world becomes as polarized as at any time since the newspaper’s founding in 1908.

We have a mission beyond circulation, we want to bridge divides. We’re about kicking down the door of thought everywhere and saying, “You are bigger and more capable than you realize. And we can prove it.”

If you’re looking for bran muffin journalism, you can subscribe to the Monitor for $15. You’ll get the Monitor Weekly magazine, the Monitor Daily email, and unlimited access to CSMonitor.com.
