Not sure if this is the right board, but it's the closest one I can find. I'm trying to find a way to call this number
800.893.893 from the UK.
Google says simply dial
00 first as this is the exit code, however dialing
00 800 893 890 doesn't work, the call immediately ends.
Also tried adding 39 which is the country code, so
00 39 800 893 890 however this is an invalid number.
Number is in Italy.
