No matter what any CDMA advocate tells you, the technology has one big disadvantage over GSM: Far fewer countries around the world use it. So no matter how great Verizon Wireless' network is in the United States, that doesn't help you when you travel to the majority of the planet. Yet Verizon is beginning to take notice of this fact and has begun to offer dual-mode cell phones that use the carrier's extensive CDMA coverage in the United States and then switch to GSM networks when abroad. Earlier this year Verizon introduced the Rim BlackBerry 8830 for the globetrotting executive, and now it offers the Motorola Z6c for a more mainstream audience. Styled like a Moto Rizr phone--though not officially part of the Rizr family--the Z6c offers everything you expect from a V Cast handset but with the added bonus of the GSM coverage. That extra functionality will come at a price; the Z6c is $229 with service, but you can get it for $179 if you buy it online. To find accessories for this phone, see our cell phone ringtones and accessories guide.
As previously mentioned, the Z6c has the same slider design you'd find on a Motorola Rizr phone. In fact, you'd be hard pressed to distinguish it from Verizon's Motorola Rizr Z6tv. Both share a black-and-silver color scheme and similar dimensions (4.2 inches by 1.8 inches by 0.68 inch; 3.7 ounces) while the Z6c has the same quality construction. You can open and close the handset with one hand using the convenient thumb grip.
The 2-inch, 65,000-color display is also unchanged from the Z6tv. It shows everything well, from graphics and photos to animations. You can change the backlight time, the dialing font size, and the clock format. Below the display is the easy-to-use navigation array. There's a four-way toggle with a central OK button, two soft keys, a camera/camcorder shortcut, a clear control, and the Talk and End/Power keys. Though all the controls are flush, they're tactile and well-spaced. Our only wish is that the OK button were raised above the toggle.
The keypad buttons are straight from the earlier Rizrs as well. Though flat with the surface of the phone, tactile ridges between the individual keys make them easy to use. We didn't have a problem with fast texting or dialing, and the bright backlighting helps in dim situations. On the other hand, users with visual impairment may find that the numbers on the keys are difficult to see in direct light.
The camera lens is located on the Z6c's rear face, but there's no self-portrait mirror or flash. The remaining external controls consist of a volume rocker and the Motorola smart key on the left spine, and a voice-dialing button, a handset lock switch, and the micro-USB port on the right spine. Unfortunately, and unlike the Z6tv, Moto moved the memory-card slot back behind the battery cover. You don't have to remove the battery to access it, but it's still rather inconvenient. You will find the SIM card slot behind the battery. The latter feature, which is necessary for GSM coverage, is a rather unique find for a Verizon Wireless phone.
Conveniently, Verizon and Motorola included several accessories in the Z6c's box. You'll find electrical outlet adaptors for the United Kingdom, Europe, and Australia. Given that the Z6c is designed to be used outside North America, the adapters are an especially nice touch. Also included is an adapter that will let you plug a 2.5mm headset into the phone's mini-USB port. You'll have to use you own headset, however.
The Z6c has a generous 1,000-contact phone book with room in each entry for phone numbers, two e-mail addresses, and notes. You can save callers to groups, pair them with a photo for caller ID, or assign them one of 11 polyphonic ringtones. Essential features include a vibrate mode, text and multimedia messaging, a speakerphone, a voice recorder, call timers, a calculator, a calendar, an alarm clock, a world clock, and a notepad. You'll also find voice commands, stereo Bluetooth, instant messaging, e-mail, and USB mass storage.
Of course, the most notable feature on the Z6c is its dual-mode CDMA/GSM support. As we mentioned earlier, that capability allows you to use the phone both domestically and in a wide variety of nations. When in the United States the Z6c uses Verizon's standard CDMA network, but when you're traveling internationally the phone will use the local transmission standard. Like previous Verizon handsets, the Z6c can roam to 22 other countries where CDMA networks are present (see CNET's quick guide to world phones for a list of CDMA countries), but you'll be able to make calls in Europe and other regions where GSM is the norm.
