Frequency Bands

When using an NB-IoT device, it is important to make sure it supports the frequency bands used by the network in your region. If your device does not support the right bands, it will not be able to connect.

What are frequency bands?

Mobile networks operate on specific frequency bands (like radio channels).
Your device must “tune in” to the same band that the network uses.
NB-IoT networks around the world use different bands depending on the country and mobile operator.

Global NB-IoT Bands

Here are the main NB-IoT bands used worldwide:

Band	Frequency (Downlink / Uplink)	Regions / Typical Use
Band 1	2100 MHz / 2100 MHz	Asia, parts of Europe
Band 3	1800 MHz / 1800 MHz	Europe, Asia, Africa
Band 5	850 MHz / 850 MHz	Americas, Asia
Band 8	900 MHz / 900 MHz	Europe, Asia, Oceania
Band 12	700 MHz / 700 MHz	USA, Americas
Band 13	700 MHz / 700 MHz	USA (Verizon)
Band 18	850 MHz / 850 MHz	Japan, Americas
Band 20	800 MHz / 800 MHz	Europe, Asia
Band 26	850 MHz / 850 MHz	Americas, Japan
Band 28	700 MHz / 700 MHz	Asia-Pacific, Oceania
Band 66	1700/2100 MHz / 1700/2100 MHz	Americas

Common NB-IoT Bands in Europe and Asia

If you are using your device in Europe or Asia, these are the most common frequency bands:

Band	Frequency (Downlink / Uplink)	Regions
Band 1	2100 MHz / 2100 MHz	Asia (some countries)
Band 3	1800 MHz / 1800 MHz	Europe, Asia
Band 5	850 MHz / 850 MHz	Asia (some countries)
Band 8	900 MHz / 900 MHz	Europe, Asia, Oceania
Band 20	800 MHz / 800 MHz	Europe, Asia
Band 28	700 MHz / 700 MHz	Asia-Pacific, Oceania

How to check compatibility

Find out which bands your mobile operator uses for NB-IoT in your country.
Check your device’s specifications to see which NB-IoT bands it supports.
Make sure your device supports at least one matching band.

If your network uses Band 20 (800 MHz), your device must list Band 20 under supported NB-IoT bands.
