What distinguishes Dolphin IT from other Internet providers?

Dolphin IT is, in contrast to the well-known large corporations in the telecommunications industry, a small medium-sized company with a regional focus. We specialize in customer-specific features and can deliver optimal solutions that you miss with the big providers.
Our Dolphin Connect products close this gap.

Our team is highly dedicated and puts your needs first, a trait that is very rare in the market.

Instead of call centers, we rely on personal contacts as well as quality instead of quantity.
