So, you want to stay in touch when cruising outside of cellphone coverage areas. One of the best choices is a portable satellite phone. With some phones offered free with coverage plans, a sat phone might rank as the most cost-effective means of global voice and ­text communications.

Today there are a number of sat-phone models and calling plans ranging from $26 a month to thousands of dollars a year. Three of the major brands are Inmarsat, Iridium and Globalstar. The Inmarsat IsatPhone 2 features a water- and shock-resistant design, and retails for as little as $599, but retailers such as satellite offer it free with an $89.95 (100 ­minutes per month) monthly plan and a one-year contract. The IsatPhone 2 features global coverage (with the exception of the poles), GPS, Bluetooth, SMS, an SOS button, and a battery that powers eight hours of talk time.

Iridium’s Extreme 9575 sat phone retails for as little as $705 with a deluxe case at Basic plans start at $39.95 a month for global coverage, but you need to pay an additional $0.99 for voice calling (in or out) and $0.50 for an outgoing text message.
