FAQ
What are the IoT One Rate Details?
Must use AT&T approved IoT LTE-M or NB-IoT device. Each device must have a separate unlimited data plan. Pooling data across devices is not available. Excludes applicable taxes and fees. Charges not pro-rated if service cancelled before end of term. Maximum throughout speed on unlimited plan is 64kbps.

LTE-M currently is available on the AT&T network in the US, and Mexico, and roaming carriers in select other countries. NB-IoT currently is available on the AT&T network in the U.S.
What are the differences between the two networks?
LTE-M has a higher bandwidth and lower latency compared to NB-IoT. LTE-M also has the ability for devices in motion and voice over LTE (VoLTE). LTE-M is a better fit for use cases that may be latency sensitive, require over the air updates, or applications that require devices in constant motion.
Where are LTE-M and NB-IoT deployed globally?
LTE-M and NB-IoT networks are deployed by carriers across the globe, available in over 60 countries and territories. The latest list can be found at https://www.gsma.com/iot/deployment-map/. AT&T is working to enable roaming for these technologies.
