Sending Omnia router back to which address exactly?

Good morning to Omnia Turris team,

I decided to send Omnia Turris router incl. all accessories back.

Only internet connection that is possible at my location is LTE and Omnia router is not stable in this respect.

Our ZTE router from austrian provider Drei is far more stable so far.

Can you please let me know exact address where I can return the router back?

thanks in advance
kind regards

I don’t know if it is possible to send Omnia back for refund.
First you need to ask them on tech(dot)support(at)turris(dot)cz


well I contacted support specialist from and she is telling me I can send it back.
Still, I´ll try this email address you just gave me too, if any answer comes back.
thank you very much
