Is the Lidle Internetflat also suitable for my tablet or laptop?

So far I have a mobile WLAN router from 1&1 and I would like to ask if I can also use a SIM card from Lidle. Unfortunately I could not be given any information in the Lidle branch. Does anyone have any idea?

As long as the mobile router is not blocked for other providers, Lidl also runs.

The only thing that can be is that the LTE speed is not supported by the route because it may not support it. So you may not be able to use the maximum speed of the Lidl Flat, but replacing the router hardware could fix that.
