What LTE frequency bands are used by emnify SIM cards in specific countries?

Customers often want to know what "frequency band" is supported by the emnify SIM card.

The emnify SIM card itself doesn't determine the frequency bands. It's the radio module in the device that must support the bands used by the operator(s) in the countries where the device will be used.

Radio modules (and hence the device) are produced for a region (e.g. EMEA, North America) or for use globally. Certification of of the module/device also typically follows this regional/global approach. 

If you are interested in the frequency bands, there are some online resouces that may be of interest:

In addition for information specific to LTE-M and NB-IoT (not standard LTE), emnify provides a list frequency bands per operator on the dedicated emnify coverage pages:
