Does Digi offer cellular data plan options for the Digi XBee Cellular modems?
Yes. Digi offers cellular service which is bundled with free Digi Remote Management to remotely monitor and manage devices, along with the capability to do over the air (OTA) remote firmware upgrades.

What’s in the Digi XBee Cellular Development Kit?
- Digi XBee Cellular embedded modem
- 1 Digi XBee development board
- 1 SIM
- 6 months of free cellular service (5MB/Month)
- Antennas and power supply
There are two U.FL connectors on the Digi XBee Cellular, for primary and secondary antennas. Do I need to use both antennas for the modem to work?
The primary antenna is used for transmitting and receiving, while the secondary antenna is only used for receiving. It is recommended to use both antennas for optimal performance, but it is possible to use only the primary antenna. Note this could reduce performance and signal strength of the device, which will vary depending on the environment and range to the nearest cellular tower.
If only one antenna is used, will the Digi XBee Cellular modem still be carrier end-device certified?
Yes. The modem has been certified for both single and dual antenna configurations. More information on antenna specification requirements can be found in the User Guide.
The development kit includes 6 months of free cellular data service. How much data can I use per month? How many SMS messages can be used per month?
6 months of free cellular service will be limited to 5MB/month and recommended to use 100 SMS per month or less. The kit is for testing purposes only, not for production.
What happens if a customer goes over the set data limits (5MB)?
If only over by a little (1-2MB), nothing. If over by 10MB in a given month, customer will be contacted by Digi to determine if a larger plan is required.
Can customers provide their own SIM for testing purposes?
Yes, they can use their own SIM if they prefer.
Does a customer need to purchase a support plan to get help with technical questions when evaluating a kit?
No purchase required, free base email support is available for customers evaluating product with a development kit.
Does Digi XBee Cellular have GPS capabilities?
No, GPS is not supported on the modem.
Is Digi XBee Cellular a drop-in replacement for other Digi XBee modules?
Yes, but customers need to evaluate the power supply of their designs to verify that they can support peak transmit currents up to 1A, which is required for all LTE CAT 1 cellular radios.
How long does it take the module to wake up from Deep Sleep and start communicating over the cellular network?
It takes about 20-30 seconds to wake up and begin transmitting over the network.
What is the difference between Transparent Mode and Bypass Mode?
Transparent Mode acts as a serial line replacement. The device queues all serial data it receives through the DIN pin for RF transmission. When a device receives RF data, it sends the data out through the DOUT pin.
In Bypass mode, the device acts as a serial line replacement directly to the cellular component. In this mode, Digi XBee Cellular Modem exposes all control of the cellular components AT port through the UART.
What is the difference between Digi XBee Cellular and NimbeLink?
A cellular breakout board like NimbeLink will include the cellular module, and may add end-device certification, a SIM slot, and a simple power supply and antenna connector. The Digi XBee Cellular hardware is fully integrated with an on-board cellular module, ARM Cortex M3 microcontroller, power regulator, and security chip, all packed into the small 24.4 x 32.9mm XBee through-hole footprint. This enables a number of useful features on Digi XBee Cellular that are not available on breakout boards like Nimbelink, including the Digi XBee software interface, critical security features, sleep modes, and on-board programmability to name a few.
