Question about Digitec iot Data Flat

We used digitec iot Daten Flat 300Mbit/s for an external construction office with 2 workstations.
Among other things, for database application with VPN access to external server, office applications, sending mail with large PDF attachments.
With digitec iot Daten Flat 300Mbit/s not super-fast, but completely sufficient for efficient work....

In a 5G Fritzbox router we reach about 30 Mbit/s. The 300 Mbit/ are never reached.

This is likely to be problematic, because the maximum download speed you can get is 300 Mbit/s. And that is hardly achievable as a rule. And that is hardly achievable as a rule. That sounds like very little, and it's obviously only 4G speed. I would look for an offer with 5G speed, which can download at up to 2 Gbps. The Digitec offer would work, but it's not likely to be fast.
