To call Portugal:

1. Dial the international access code: 011 from the U.S.; 00 from the U.K., Ireland, or New Zealand; or 0011 from Australia.

2. Dial the country code 351.

3. Dial the city code (don't include the 0), and then the number.

To make international calls: To make international calls from Portugal, first dial 00 and then the country code (U.S. or Canada 1, U.K. 44, Ireland 353, Australia 61, New Zealand 64). Next you dial the area code and number. For example, if you wanted to call the British Embassy in Washington, D.C., you would dial 00-1-202-588-7800.

For directory assistance: Dial 118 if you're looking for a number inside Portugal, and dial 177 for numbers to all other countries.

For operator assistance: If you need operator assistance in making a call, dial 171.

Toll-free numbers: Calling a 1-800 number in the States from Portugal is not toll-free. In fact, it costs the same as an overseas call.

Cellphones

The three letters that define much of the world's wireless capabilities are GSM (Global System for Mobile Communications), a big, seamless network that makes for easy cross-border cellphone use throughout Europe and dozens of other countries worldwide. In the U.S., T-Mobile, AT&T Wireless, and Cingular use this quasi-universal system; in Canada, Microcell and some Rogers customers use GSM, and all Europeans and most Australians use GSM. GSM phones function with a removable plastic SIM card, encoded with your phone number and account information. If your cellphone is on a GSM system, and you have a world-capable multiband phone, such as many Sony Ericsson, Motorola, or Samsung models, you can make and receive calls across civilized areas around much of the globe. Just call your wireless operator and ask for "international roaming" to be activated on your account. Unfortunately, per-minute charges can be high -- usually $1 to $1.50 in western Europe.

For many, renting a phone is a good idea. While you can rent a phone from any number of overseas sites, including kiosks at airports and at car-rental agencies, we suggest renting the phone before you leave home. North Americans can rent one before leaving home from InTouch Global (tel. 800/872-7626; www.intouchglobal.com) or RoadPost (tel. 888/290-1616 or 905/272-5665; www.roadpost.com). InTouch will also, for free, advise you on whether your existing phone will work overseas.

Buying a phone can be economically attractive, as many nations have cheap prepaid phone systems. Once you arrive at your destination, stop by a local cellphone shop and get the cheapest package; you'll probably pay less than $100 for a phone and a starter calling card. Local calls may be as low as 10¢ per minute, and in many countries incoming calls are free.

Voice Over Internet Protocol (VoIP)

If you have Web access while traveling, you might consider a broadband-based telephone service (in technical terms, Voice-over Internet Protocol, or VoIP) such as Skype (www.skype.com) or Vonage (www.vonage.com), which allows you to make free international calls if you use their services from your laptop or in a cybercafe. The people you're calling must also use the service to make the call for free; check the sites for details.

Internet/E-Mail

Without Your Own Computer -- To find cybercafes in your destination check www.cybercaptive.com and www.cybercafe.com.

Most major airports have Internet kiosks that provide basic Web access for a per-minute fee that's usually higher than cybercafe prices. Check out such copy shops as Kinko's (FedEx Kinko's), which offers computer stations with fully loaded software (as well as Wi-Fi).

With Your Own Computer -- More and more hotels, resorts, airports, cafes, and retailers are going Wi-Fi (wireless fidelity), becoming "hotspots" that offer free high-speed Wi-Fi access or charge a small fee for usage. Most laptops sold today have built-in wireless capability. To find public Wi-Fi hotspots at your destination, go to www.jiwire.com; its Hotspot Finder holds the world's largest directory of public wireless hotspots.

For dial-up access, most business-class hotels throughout the world offer dataports for laptop modems, and a few thousand hotels in Europe now offer free high-speed Internet access.

Wherever you go, bring a connection kit of the right power and phone adapters, a spare phone cord, and a spare Ethernet network cable -- or find out whether your hotel supplies them to guests.
