However, the A790 comes to the table with an ace up its sleeve: the ability to roam on CDMA and GSM networks. You can access both Verizon's U.S.-based network and Vodafone's high-speed networks in more than 100 countries in Europe, Asia, Africa, and the Middle East. Web browsing is handled by Verizon's high-speed 1xRTT network. Switching between CDMA and GSM isn't a seamless process; to go from one mode to another, you must restart the phone, and some of the mobile's features won't work in GSM mode. For example, voice memos and commands are available in only CDMA mode, and text messaging is not available in all countries. Also, before you start phoning home from far-flung locales, save your pennies. Though the A790 comes with a SIM card for GSM, most calls made outside the United States cost $1.29 a minute, while in certain countries, such as the Maldives, Indonesia, Sri Lanka, and Latvia, the per-minute rate skyrockets to $2.49. But you're subject to long-distance charges as well. That means an additional 65 cents per minute for most countries, but it can range up to an astronomical $9.17 per minute if you ever visit Gabon. Sprint's version of the phone, the IP-A790, involves similar charges, but Sprint also makes you pay for the SIM card.
The A790's VGA camera boasts a flash and takes pictures in three resolutions: 160x120, 320x240, and 640x480. You can zoom in up to 4X in the 160x120-pixel mode, choose from a variety of color effects (including Black And White, Sepia, and Negative), use one of three quality settings, and adjust the brightness. And if you want to be even more creative, you can opt for one of four shutter sounds, as well as a silent option; alter the picture's rotation; or add one of three--somewhat cheesy--frames to your pictures, such as a white-picket fence, Christmas lights, cookies, and apples. About 3MB of RAM is set aside for photos, with the highest-resolution photos taking up about 80K of memory. Once you've snapped some photos, you can add them to the camera's gallery, use them as wallpaper for the external or internal LCD, or send them to your buddies via multimedia messaging. The photos we took looked fine for a camera phone, although the images were a tad fuzzy and washed-out for our taste.
The phone's customization features are relatively robust. In addition to being able to change the external and internal LCD wallpaper, you can choose from four different ringer profiles: Normal, Meeting, Drive, and Outdoor. You can't, however, alter the color themes of the phone's menus. More personalization options are available from Get It Now, along with ring tones and applications. No games were included in our review model, but you can always download BREW 1.0-enabled titles via Get It Now.We tested the quad-band (CDMA 800/1900; GSM 900/1800) Samsung SCH-A790 world phone in New York City. We had no trouble hearing our friends, who reported that we sounded loud and clear. Calls also were satisfactory using the included headset.
Samsung promises 2.9 hours of talk time in CDMA mode and 3.5 hours when using GSM. We beat Samsung's CDMA talk time estimates by a wide margin, coming in at about 4.5 hours in our tests. GSM talk time was not tested. For standby time, we met the promised time of five days. For such a traveler-friendly phone, however, the A790 disappointingly comes with only a bulky desktop charger. According to the FCC, the A790 has a digital CDMA SAR rating of 1.47 watts per kilogram.
