Translation of joiner in German

Can you please give me your phone number or I'll give you my phone number. Wish you a nice day, we'll here from each other. Bye. And by the way, my real name is Deborah but my friends just call me Debby.
I am learning Spanish in university but I also have to improve it for private reasons. Do you have any suggestions. It is giving me a hard time lately as it is difficult. I need to be very patient.
Thank you for your answer, your English is better than my Spanish. I live in Liverpool in Great Britain, that is a town around 300 kilometers north of London. My wife and I have 4 children.
