Actually I did a little fancy and sorted https://en.wikipedia.org/wiki/List_o...orks_in_Europe table by bands (click on the "band" column) and those are the few european carriers that are not compatible to PLS8-E in LTE mode (same carriers might still offer other LTE or UMTS bands compatible with PLS8-E, I didn't check. E.G "Sweden '3' carrier" operates bands 7, 20, 38 - the latter not supported by PLS8-E, when you want to use PLS8-E with this carrier you need to check on the carrier's network coverage map to see if the coverage by supported bands is useful for you or not):

[EDIT] latest PLS8 datasheet updates suggest it will also support Band1 ! [/EDIT]

for bands (?),1 and
for bands >20
