The Good The National Geographic Xplorer has a stylish, rugged body, a flashlight, an FM radio, and two phone numbers.

The Bad The Xplorer's call quality could be better, and it has a proprietary charger and a shared charging and headset port. Data is pricey and the cost of placing calls can quickly add up.

The Bottom Line Globe-trotters seeking a ready-made travel solution will appreciate the Xplorer's convenient Talk Abroad SIM. However, mounting expenses for a basic rugged handset will turn away existing GSM phone owners.

Editors' Top Picks

International travel can be daunting, especially when it comes to telecommunications. GSM phones give you the option of swapping in a SIM card for a network abroad, or jumping to expensive roaming. But North American owners of CDMA phones have fewer options in GSM-dominated locales. The rugged National Geographic Xplorer, aka the Samsung B2100, provides a ready-made solution with its Travel Abroad SIM, an unlocked GSM card that takes incoming calls on both a U.K. and a U.S. number, so family and friends can reach you at little cost wherever you are. However, you will pay the bill for outgoing calls and for incoming calls to the U.S. number from your prepaid balance. At a price of $179, the Xplorer comes with $29 of credit, roughly 30 minutes of calling. While it's not for everyone, the prepaid model certainly is convenient for some people.

U.S., Canadian, and Mexican customers can buy the Xplorer through Amazon.com, Buy.com, and National Geographic's online store.

Design
The National Geographic Xplorer, sold globally as the Samsung B2100 Xtreme Edition, is a ruggedized candy-bar handset that strives for a modicum of style to complement its thick, grippy skin. A small face peers out from a dusty black body lit up with cherry-red accents. The Xplorer stands 4.4 inches tall by 1.8 inches wide by 0.7 inch thick. Thanks to a rubberized coating, it feels thick and substantial with the right amount of heft at 3.6 ounces. It's also comfortable on the ear. While ridges, dimples, and bumps bulk up the Xplorer's armor, we were able to slip it into pockets without incident, though it felt a bit bulky there. The Xplorer is built to withstand shock and resist water. We're confident it can take a knocking, but as we learned from a run-in with another tough phone, even hardy handsets have their Achilles' heel, so don't try too hard to test its limits.


There is more to the rugged National Geographic Xplorer than meets the eye.

The 1.8-inch TFT display supports 262,000 colors and has a very low 160x128-pixel resolution, about a quarter of the QVGA standard for basic cell phones. The screen flashes the date and time, battery life, and signal, and is easy to navigate. You can choose from three themes or customize your own, and can adjust brightness, keypad lighting, and backlight time, and even choose what hour the backlighting will kick in at night. You can also customize font position, style, size, and color. The colors and brightness were appropriate for the low screen resolution, though everything could have popped more. The Xplorer's screen, like most screens, fades in direct sunlight, although we found the dark theme held up better to bright sunshine than the light theme.

Beneath the screen are your two typical soft keys, the Talk and End buttons, and a rectangular four-directional navigation pad with a central Select button. The alphanumeric dial pad sits directly below. All the dialing and navigation buttons feel spacious enough; they're fully separated and rise above the surface, so it is possible to dial by feel. That rubber coating makes them feel ever so slightly scratchy to the touch and less responsive than other dial pads we have known, requiring a firmer press. Still, we had no problems dialing or composing text messages with predictive text.

As part of its rough-and-tumble ruggedness, the Xplorer has some interesting design elements, like raised mounds for the volume rocker and the flashlight button on the left spine, the aforementioned flashlight up top, and a swooping loop for tethering the Xplorer to your belt or pack. On the right spine there's a more pedestrian (and disappointing) shared port for the charger and a headphone. It's bad enough there's no standard 3.5mm headphone jack, but Samsung has added insult to injury by making this port proprietary rather than Micro-USB. While the packaging does include an adapter plug with some earbuds, upgrading to new headphones would be a hassle. The shared port also makes it impossible to play music or speak through a wired headset while charging the phone.

Another slight disappointment is the lack of a hardware camera shutter to complement the 1.3-megapixel camera on the phone's back.

There is a microSD card slot for up to 8 MB of extra storage, hidden behind a screwed-on back cover to help protect it from the elements. A small coin should be sufficient to gain access. Locking the card behind the battery would ordinarily be a design mistake since swapping it requires turning off the phone, but the device's rugged philosophy makes the inconvenience understandable.

In addition to earbuds, the Xplorer comes with various globe-trotting charging adapters in the box.

Talk Abroad service
Although its ruggedness is an asset, particularly for more adventurous types, the Xplorer's Talk Abroad SIM card is its real raison d'etre. The SIM card outfits you with one U.S. and one U.K. phone number that your contacts can call at any time. Talk Abroad has partnerships with GSM carriers worldwide, and gets coverage in about 200 countries. Incoming calls to the U.K. phone number are free to you in 70 countries, but calls routed through the U.S. phone number will deduct 25 cents per minute from your prepaid cache.

Costs can quickly mount this way, depending on the zone you're calling to. Most metropolitan areas will levy a 90 cent-per-minute fee for landlines, while calls to mobile phones will cost about $1.15 per minute. Prices shoot up in more remote areas. You can top up your minutes online or by texting a short code.


Up top is a hook for attaching the Xplorer to your stuff, and there's a handy push-button flashlight in the phone's spine.
