Centro runs on Verizon Wireless' high-speed data network, which gives customers the ability to quickly send and receive e-mail messages and attachments and browse rich Web content. It also allows you to use Centro as a modem for their laptops when they subscribe to Verizon Wireless' BroadbandAccess Connect service plan.

Centro's built-in Google Maps application delivers directions and lets users perform local searches and view moveable/scalable maps, satellite imagery and traffic updates. You can also map a contact's address directly from the contact application simply by selecting the "maps" button.

VersaMail 4.0 with built-in Microsoft Exchange ActiveSync support for Microsoft Direct Push Technology allows for the delivery of e-mail and calendar updates from a home or office PC using Outlook to Centro.

Centro users also have the option of using Wireless Sync, Verizon Wireless' proprietary e-mail solution, for access to personal or corporate e-mail, contacts, calendar and tasks from their home or office PC. Wireless Sync supports POP3 or IMAP e-mail accounts and it supports Microsoft Exchange, IBM Lotus Notes and IBM Lotus Domino.

An unlimited monthly data plan for Web browsing and e-mail support for up to eight personal e-mail accounts costs $30 a month on top of your voice plan.
