3G modems with memory card slot

Memory card slot

— memory cards are widely used in portable (and not only) electronic devices both for expanding the built-in storage and as removable media for data exchange. Such media rarely contains information that directly affects the operation of the wireless modem; therefore, models with memory card slots are typically used to allow other devices to access the contents of the card. The way to provide such access can be different: some modems can work as an external USB card reader, others can work as a local file storage connected via Wi-Fi.
