How to connect my own modem

[Manä7]

I begin to contract from the day before yesterday.
I do not know how to connect my own modem.(Fritz box6660)

Please tell me how to activate appliances.

To whom may I email?

I cannot call a telephone because

 I cannot speak german language.

I called once, but they couldn't get through to me in my poor English.

Or should I give up the connection and cancel the contract?

Could anyone give me some advise?

Which state you are come from?

Thank you for your reply.
I came from Asian country for business.

I understand the biggest problem is that I can't speak German, even though I started living in Germany.

Thank you for your reply in English
I live in Noordrhien-Westfalen.

I did some Googling, it is stated it is acceptable by telephone in NRW. 

I'd like to know if there's any other way.

Your link was very helpful. 
My problem has been solved. Successful internet connection. Thank you so much for your help.

I installed WhatsApp and contacted them. At first it was an automatic response from Tobi. I had already tried SMS messages, so it was the same response. When I continued the dialogue with Tobi on WhatsApp, the service team was summoned. Service team gave me messages.
