Zoom® Ships 3G+ Freedom Modem for AT&T and T-Mobile

Unlocked 7.2 Mbps USB Modem Allows Choice in Cellular Internet Services and Plans

BOSTON, MA--(Marketwire - October 18, 2010) -  Zoom Telephonics, Inc. (OTCBB: ZMTP) announced today the first shipments of the Zoom 3G+ Freedom Modem, Model 4597. The full-featured 3G+ USB modem works on a range of services worldwide, including both AT&T and T-Mobile in the USA. Since model 4597 is not "locked" to a particular service, its owner can easily choose and change service providers. The 3G+ Freedom Modem works with prepaid and pay-as-you-go cellular Internet services, so its owner can avoid the expense and obsolescence risk of long-term service plans. 

The 3G+ Freedom Modem is activated by plugging in a small card, called a SIM, which can be obtained at a mobile phone store. Changing a service provider is done by simply unplugging one provider's SIM and replacing it with another provider's SIM. This makes it easy to select the best service provider based on a number of factors including service availability, service speed in a location, and price. 

Model 4597 supports three high-speed cellular data frequencies, including the 1700 MHz (AWS) frequency used by T-Mobile for its highest speeds in the US and the 850 MHz and 1900 MHz frequencies used for the highest AT&T 3G speeds. The Freedom Modem supports a data rate of up to 7.2 Mbps on downloads and up to 5.76 Mbps on uploads, though this data rate also depends on the service provider's data rates at whatever location you select. 

"Mobile broadband pricing, coverage, and speeds are changing at a rapid rate," said Frank Manning, President and CEO of Zoom Telephonics. "As an unlocked modem with all the popular high-speed frequencies used in the USA, Model 4597 gives users the flexibility to pick the service they want based on key issues like broadband coverage, the user's location, price, and type of service plan." 

The 4597's pivoting, retractable USB connector allows easy installation in cramped spaces, orientation of the modem for the best possible connection, and protection of the connector during transport. Other features of Model 4597 include a micro-SD slot that accepts a memory card for up to 16 GB (Gigabytes) of portable memory. Simply sliding in a micro-SD memory card allows the modem to double as a storage device. The estimated retail price of model 4597 is $99.
