  3. Place the widget (note: it’s only a widget not an app, don’t scurry around searching for app icon) on your home screen. And tap the “Configure” button.
  4. Enter your username and password (in most cases you don’t need to better leave blank). Enter the connection string as *99# for GSM (mostly if you’re using an unlocked modem) connections and *777 for CDMA (likely if the modem was provided by the operator, Photon+ for instance) and the network access point (APN). Contact your operator for more details and settings.
