Don't use Cellmapper to try and see whether you're aggregating, I don't find that the user interface for that is friendlyDoes anyone know if EE 5g masts are capable of N1+N28 aggregation? Assuming i'm using newer (X62 onwards) hardware that is capable.
My Honor Magic 5 Pro using cellmapper shows the presence, but often gets steered back to N1 with dual B3 bands in aggregation.
