I'm outside of wifi coverage for maybe 30 minutes a day, on my bike ride to/from work and a visit to the supermarket. 3G/4G coverage is practically 100% (actually 99.5%), only when you get close to the national borders there are some white spots because they aren't allowed to broadcast too far over the border and interfere with networks in Germany or Belgium. There actually was a bit of outrage over that last 0.5% a while back due to emergency services not being reachable in those areas and the mobile operators had to make promises to cover those areas as well. So yeah, coverage is pretty much total.
