     Whether you're headed to another country for business or pleasure, it is likely that you need to keep

in touch with family or business partners in the United States. But if you plan to do that using your cell

phone, you could have an unwelcome surprise-U.S. cell phones don't work abroad. U.S. companies use

different forms of technology, not like most of the international community, including Europe.

     However, there is an easy, cost-effective solution(方法) to staying in touch while you're traveling.

You Can rent a phone that is guaranteed to work in the countries you're visiting. Roadpost offers a 30-day cell phone rental plan that includes free incoming calls, free voicemail and call waiting services.

     The service is convenient and simple. You can place your order online and your phone will be shipped

to arrive on the date you want. If an unexpected business trip comes up, Roadpost can provide next-day

delivery for most cities. In addition to the phone, Roadpost provides a spare battery, travel charger and

a leather carrying case.

     When your phone is shipped from Roadpost, you receive an e-mail confirmation that contains your

international cell phone number so you can leave it with family members and business partners; Roadpost

even provides business cards preprinted with your international phone number.

     Those who don't want to be without e-mail while traveling can rent an international BlackBerry. It can

be hard to stay in touch by e-mail when traveling. With an international BlackBerry, you can email as

much as you like, without worrying about an expensive bill. If you're traveling to very remote areas, you

may want to consider renting a satellite phone: Because they receive their signals from satellites, these

phones work anywhere on the planet, including oceans and mountains. When you return, simply ship the

phone or BlackBerry back to Roadpost using the return kit the company provides.
