TV Box Installation

Hello!

I have upgraded my program from internet only (400 Solo Max) to TRIO MAX NET+TV+MOB.

I already have internet installed. I have received today and activated the SIM Cards.

I booked an appointment for TV Box Installation on the 8th of December but today I had a voice message (unfortunately for me in French) that I should contact VOO because there is a problem with the appointment.

Can I just receive the TV Box by post and install it by myself? Does a technician have to come? There is an ethernet and HDMI cable waiting next to my TV.

Note: I have no clue which tv decoder I have ordered (box evasion or VOO corder) :/

Thank you in advance for your help.

With kind regards, 

Chris
