What simple steps should you follow to successfully add someone on WhatsApp and ensure their number syncs with your app?

After a meeting with a potential client, I needed to add his contact to WhatsApp for a quick chat. Following the guide on how to add someone on whatsapp, I easily accomplished this task. After saving his number in the correct format and updating my contact list, I immediately saw him in the app.

Grateful for interesting and helpful comments on the topic!
