Landlines are vanishing, but there are still plenty of reasons to have one.

They’re reliable, easier to reach in an emergency, don’t run on batteries, and will never get lost.

But forget paying for your landline service…

Instead, get free service through a company called Ooma. You’ll pay a one-time fee for hardware and activation—and that’s all. The service includes call waiting, caller ID, and free calls anywhere in the U.S.

Ooma also offers super-cheap international packages. You can call 70 countries for less than a penny per minute.
