Set WhatsApp as my default messaging app.

Press and hold on the messaging icon at the top of their contact, and you should get a menu of messaging options.

Select Whatsapp if available. Should be if the number in the contact is the same as the full whatsapp contact number.

The Messaging icon will change to read Whatsapp instead of Message, and you can then use it directly to go to the Whatsapp chat for that person.

You can change it back by selecting "Message" from the menu. After a couple of times of selecting messages over Whastapp it will make the messages option the default again.

It will change depending on which option you use more often.

Your welcome. Yes it works on a contact by contact basis unfortunately.

Well, that's pretty cool. I didn't know that. Thanks.

That is not an option.

You can submit feedback to Apple suggesting they offer such a feature here:

Is this a permanent change, Phil? Or just a one time thing?
