WhatsApp not showing contacts

[Ella Corrella]

I have WattsApp on my old iPhone 4s and I can chat and speak with a friend in Spain. I have recently bought a Huewei, installed WhatsApp and but in contacts my Spanish friend is not there, as though she does not have WhatsApp, but I know she does. WhatsApp obviously has access to Contacts, how can I get to WhatsApp my Spanish friend on the Huawei please!
Thanks in advance.....
