3.3.1
Your USB Modem or Phone Does Not Work With the Router
If your USB data modem or phone is not working with the router, check the list of supported devices to ensure you
are using a supported device and carrier. The device you‟re using must be supported on the carrier network
providing your cellular service or it‟s considered an unsupported device, even if it is supported on another carrier‟s
network.
CradlePoint‟s supported device list changes regularly. We update our supported device list after a device is
certified and approved. If the device you have is NOT on the list, that means we do not support it at this time.
The SUPPORTED DEVICE list can be found at:
