4G network compatibility in France I read somewhere (here) that in France, in order for the 4G to work ideally with all carriers, one should have a smartphone with the 4G network spec: "FDD-LTE : Bands : 1/3/7/20/28".

I am considering buying the Moto G5 model XT1685 for my brother who lives in France. According to this site, the 4G network specs of this phone read:

LTE Cat6 700/800/850/900/1800/2100/2600 (Bands 1,3,5,7,8,19,20,28)
TD-LTE 2300/2500/2600 (Bands 38,40,41)


I can't figure out whether it is a problem or not that I am not seeing "FDD" in these specs. In short: will this phone work perfectly fine in France? Thank you!
The only duplex modes of LTE are TDD and FDD (see band list on Wikipedia) - in other words, non-TD-LTE bands are FDD-LTE.

Generally Europe uses band 20 extensively, but you are still advised to consult your particular carrier.
