Verizon Jetpack® MiFi® 7730L - Connect a USB Mass Storage Device
When a USB mass storage device is connected, folders and files can be shared with connected devices on the Jetpack's Wi-Fi network.
Only the USB type-C port can be used for sharing. The USB type-A port is available solely for charging a phone or other portable devices.
A USB type-A to USB type-C connector can be used to connect a USB-type A mass storage device.
A connector isn't included with the Jetpack, but can be purchased via a 3rd party (non-Verizon) retail store.
With the Jetpack powered on, connect a mass storage device to the Jetpack's USB type-C port located on the bottom edge.
Allow several seconds for the Jetpack to recognize the storage device.
From the Jetpack's display, tap Share.
Review the message then tap OK to confirm.
To safely remove the storage device, navigate: Menu > MiFi Share > Eject then tap Confirm.
