4G LTE/5G Europe frequency M5 vs M6Pro

hi,

I purchased an M5 but haven't unpacked it yet.
I hesitate to swap it for an M6Pro as it has more frequencies in the 5G bands.

l am comparing the 4G LTE and 5G frequencies (Europe) between the Netgear Nightgear M5 and the new M6Pro.

I have the impression that the M5 is missing some frequencies compared to the M6Pro and that this might make connection not possible on some cellular masts.The frequencies missing from the M5 is this a problem towards possible connections that cannot happen?

Please your advice.
