Possibility of using a Sodaq SARA AFF R410M with the KPN M2M 4g network

Hello everyone, for a Arduino project we want to test Both the M2M and LTE M capabilities of the KPN network. The main difference we found between M2M and LTE M is that M2M will be connecting continuously with the KPN, while LTE M only does not. We were wondering if that would be possible on the Sodaq SARA AFF R410M board or that the R412M board might be a better option.
This is the information KPN gives themselves about their M2M network:

Dear @Haopse,

The difference between the R410 and R412 is that the R412 also supports 2G.

R410 = NB-IoT and LTE-M
R412 = NB-IoT, LTE-M and 2G

More information about the differences between both modules can be found here:

Let me know if you need more information.
