Whatsapp history backup

A few days ago I lost my iPhone with no Whatsapp backup.
i purchased a new iPhone and SIM card and downloaded a WhatsApp and I didn't have any information but my exciting groups.

two days later - luckily, I found my old iPhone that I would like to go back to.

How can I make sure that when I put the new SIM in the old iPhone I will get the Whatsapp history? (of course without the last couple of days with the new phone)

If ill insert the sim and open WhatsApp it will keep all my history?
there is a way to back up now my WhatsApp on my old iPhone?
