Their website doesn't seem to specify which GSM bands it has (simply "More Bands and Band-Combinations for better reception"). I want to know how much of a given provider's spectrum I'd be missing out on trying to sneak one of these to the states.
TL;DR: By adding band 66, Fairphone 5 has better compatibility with cellular network providers in the USA. Band 48 also gives better compatibility with Verizon. T-Mobile is still the best for Fairphone in the USA.
Thanks! Yeah, it looks like it covers T-mobile minus the GHZ/ mmWave bands, which is good for me. A solid consider, especially if they (eventually) drag it over to the states like the Fairphone 5.
