The Option ICON 322 is an excellent modem to use with NowSMS to send and receive SMS and MMS messages.
This modem is readily available in the United States, as AT&T sells it as the “AT&T USBConnect Quicksilver”.
If you are using an unlocked version of this modem, do not install the software that is included on the USB drive of the modem, which may be branded for a specific carrier. Instead, download the modem driver software from
You may encounter a problem where NowSMS complains that the modem is already in use. The GlobeTrotter software that installs with the modem drivers may try to automatically make a data connection each time Windows is restarted. If this happens, load the GlobeTrotter software by clicking on its icon in the Windows tray (right side of the Windows taskbar, near the date and time display). Open the GlobeTrotter software and press the “More” button, then uncheck “Auto Connect”.
