DELTA Mobiel sells mobile plans to people in the Netherlands, but Veritaset does not compare its offers yet. Its website refuses automated reading, and we respect that. We collect such operators' plans by hand instead, from the operator's own website in a normal browser; until that is done, its plans are not compared.
What we found
Plain requests get a 403 and a fake maintenance page (bot protection), although robots.txt allows reading.
Until its plans are collected, check DELTA Mobiel's offers on its own website.
