Blackberry Bold 9620
The RIM BlackBerry Bold 9650 is a world phone with dual-mode functionality, meaning that it supports both the CDMA and GSM networks. Here in the States, the smartphone will work on Verizon's network as usual, but when you travel overseas, it will automatically detect and connect to a GSM network, so you can continue to make calls and receive data. Like the Tour, the Bold supports the 2100MHz UMTS/HSDPA band, so you can get 3G support overseas.
In addition, the Bold is Verizon's first smartphone to support the carrier's GlobalAccess Connect service, which allows you to use the Bold as a tethered modem while abroad. Plans start at $65 per month with a 5GB data cap in the U.S. and Canada (5 cents per MB overage fee) and 100MB allowance in select countries ($5.12 per MB overage fee). Though the Bold ships with a SIM card, Verizon will allow customers to unlock the SIM as long they have been a customer for 60 days and are in good financial standing with the carrier. Unlocking the SIM will allow you use an international SIM card, but note that you can't pop in a T-Mobile or AT&T SIM for domestic use. In all, you'll get voice coverage in more than 220 countries and data coverage (e-mail and Internet) in more than 200 countries, 110 being 3G.
