Unlimited texts come with every mobile plan which cost more than 20€,
even when it's not unlimited the rates are really cheap and you don't pay for received texts ever.
MMS were never part of the data plan either, when you get unlimited SMS it always comes with free MMS.
afaik, using whatsapp require you to have a data plan, and in France you'll almost always get unlimited texts before data plans
