How can i delete multiple contacts by selecting them,as there are a lot of contacts i want to delete and i can’t do it one by one

Contacts are neither stored locally on an iPhone nor in SIM. They are synced to an email account that you had Google, iCloud, AOL, Exchange, Outlook, Yahoo or any Other

1. How many Contacts account (email client server) you have?
2. What is your default Contacts Account?
3. Which email account you are using to store Contacts?

• See the GIF below for Contacts and Default Account

Hello there! There's no way to select contacts in Contacts app. You have to delete them one by one.

Sorry, but you cant :-C

On phones
