In Greece no ISP offers symmetrical. Fiber connections are 50/5, 100/10, and 200/20. There was a pilot program for 1Gbit symmetrical but it never made it to consumer market.
As someone else mentioned there are some smaller players who give kind of symmetrical but their coverage is way too small, like 10% of major metropolitan areas and nowhere else.
Residential broadband excluding Athens is mostly down to 50/5mbps and in many suburbs in cities (e.g. Khania, Crete) don't even get more than 1mbps upload.
Yet we have politicians and commercials all day showing how '5G' will change our lives. It's a joke.
