sold Iphone without erasing data
I restored my iphone on itunes and sold it few days ago.
Buyer couldn't access because phone is linked to my apple ID, so i logged into find my iphone, placed a request to erase iphone and while the request was pending until phone get connected to Wifi; I removed the iphone from my account. I changed my apple id password and deleted everything on icloud
my question is can the new buyer get to see my data and photos or it will be deleted permanently. and if yes, what can I do about it.
iPhone 6s
