Finally, a cell phone

That's… a phone

With rates as low as $3.75 per week !

"Well, I finally did it. I finally decided to enter the digital age and get a cell phone. My kids have been annoying me and the last straw was when my car broke down, and I was stuck by the highway for an hour before someone stopped to help. But when I went to the cell phone store, I almost changed my mind. The phones all have cameras, computers and a "global-positioning" something or other that's supposed to spot me from space. Goodness, all I want to do is to be able to talk to my grandkids! The people at the store weren't much help. They couldn't understand why someone wouldn't want a phone the size of a postage stamp. And the rate plans! They were confusing and expensive… and the contract (合同)lasted for two years! I'd almost given up until a friend told me about her new Jitterbug phone.  Now, I have the convenience and safety of being about to stay in touch with a phone I can actually use. "

Affordable plans that I can understand一and no contract to sign (签订)!

Unlike other cell phones, Jitterbug has plans that make sense. Why should I pay for minutes I' m never going to use? And if I do talk more than I plan, I won 't find myself with no minutes like my friend who has a prepaid phone. Best of all, there is no contract to sign, so I m not locked in for years at a time. The US-based customer service is second to none. And the phone gets service anywhere in the country.
