To obtain information on how to upgrade your U.S. Robotics Modem, call the U.S. Robotics Modem Upgrade Center at 1(888) 877-9896.

All Courier modems are eligible for some type of software and/or hardware upgrades to x2. Please call (800)231-8770 for more information on your Courier modem.

In addition, all U.S. Robotics Sportster 33.6 Winmodem faxmodems are upgradeable to x2, regardless of purchase date.

To be eligible for an other Sportster x2 upgrade, however, you must provide proof that the modem was purchased on or after 8-15-96. 
If you purchased your U.S. Robotics Sportster modem before 8-15-96, your modem was not built to be upgraded to x2 technology.

To find out how to purchase a new U.S. Robotics modem, go back to the previous panel and click the "Other" button.

Be sure you have your modem's serial number available for the U.S. Robotics representative.

For external modems, the serial number can be found on a white sticker on the botton of the modem or on the outside of your modem's original box.

For internal modems, the serial number can be found on the modem's PC board.
