Can’t enter a contact in Whatsapp

[Android Central Question]

Hello,
A friend gave me his mobile number 06 84…
We are french, I live in France but he lives in Belgium. If I try +33 6 84… (33 for France) whats app doesn’t recognize it ; if I try +32 6 84… (32 for Belgium) whats app doesn’t recognize it neither.
Some one has an idea ?

Thank’s,
Bye
