Deleting a contact on your device will not remove it from your Telegram app until you delete synced contacts.
Removing a contact from your Telegram app will not delete it from your device. And this deletion is temporary, and that contact appears on your app again.
To remove the contact permanently, you need to do this after deleting it: Disable contacts sync on Telegram or remove that contact from your device.
Let’s find out how to remove a contact from your Telegram app. I use an Android phone, PC (Windows 11), and iPhone.
Note: Removing a contact will not remove its conversation.
Delete a Telegram Contact from Your iPhone
Launch the Telegram app and tap the Contacts tab at the bottom.
Hit the contact you want and tap the name at the top.
Tap the Edit at the top right and select Delete Contact.
In the pop-up, tap Delete Contact, and that’s all.
Delete a Telegram Contact from Your Android Phone
