Onlinehelp 24


Onlinehelp24 was founded to fix computer problems for private and business customers remotely and hassle-free. With fast internet connections and mature remote maintenance software it is easy to solve computer issues without being on-site.

In the course of time we extended our service and product portfolio significantly. We realised that customer contact is essential for establishing trust and a good relationship.

That's why we see ourselves as an IT service contractor, who supports quickly and straightforward with secure remote tools but still look forward to have a close client connection. See on the next pages what we can do for you.
