My title clearly says how to move whatsapp business to iphone whatsapp business. I have already had whatsapp messenger migrated to iphone. Just need to get business whatsapp transferred. As for the third part apps, i have tried some 5 of them now and none are free. I dont wanna invest so much for something that is 1time and who knows what guarantee they offer

this answers the exact opposite of what i asked. I need my whatsapp business in android to whatsapp business on iphone
