Well, even 2G is not very reliable here in The Netherlands on my Jolla phone (at least on my carrier T-Mobile, I've heard better things from Dutch Jolla users on other carriers). Other than that, I'm happy with my Jolla phone. Even 4G works very nicely. It's just that T-Mobile kinda ***** in providing enough 3G/4G coverage even though I'm living in a big city that keeps on growing so sometimes I have to rely on 2G and it's not so good on the Jolla phone because I have to be very lucky to be able to even place a call on 2G which works fine on 3G and 4G.
