To tell you the truth, I' m not interested in owing a cellular phone(便携式电话) except for use in an emergency (紧急情况), for ordinary cellular phone service is very expensive. How would I get help if I were in trouble or in danger？ A good friend told me a product she thought would settle my problem. It's the SOS phone--a cellular phone service designed for emergency use.
With the touch of a button the SOS phone will connect me to a roadside emergency service, a 911 service or a trained service SOS operator, 24 hours a day. If I ever need help, I know it's just a phone call.
By pressing the "Tow" button, I'll be connected with my emergency roadside service provider(提供者), or if I don't have one, the SOS operator can suggest one to me and get in touch with them immediately.
The"911" button will connect me to 911 emergency service in my area--best of all, the call is completely free!
If I just want to call home to tell my husband and children something necessary, I can press the "Call" button. Then I'll reach an operator. When I asked the operator to call home, I'll be connected automatically(自动地). And because the Call Center has my 10 most-used phone numbers, I don't even have to recite the number.
Unlike ordinary cellular phone plans, the SOS phone doesn't have any minimum usage requirements (最低底价) or other promises that could change the price I expect to pay each month.
