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 cellphone, you could have an unwelcome surprise—U.S. cellphones 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 to staying in touc
h while you’re traveling. You can rent a phone that is guarante
ed（保证）to work in the countries you’re visiting. Roadpost offers a 30-day cellphone 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 a
rrive 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（确认）that contains your international cellphone 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 e-mail as much as you like, without worrying about an expensive bill. If you’re traveling to very remote areas, you may want t
o consider renting a satellite phone, because it receives its signals from satellites, this phone works 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.
