Dear @silvia
can you please tell me what are the supported combinations by RM520N-EU and RM520N-GL? Because this is not clear at all and it’s something that a customer has the rights to know in order to make informed purchasing decisions. Even more given the issues people reported here.
I repeat again my tower details and there is no difference in the supported bands for both the modules in relation to that tower (supposing the above specs extracted from your pdf are the more recent ones):
Thanks
