No, you don't need antivirus for your smartphones unless you download to choose an app from unknown source. A lot of Android viruses are installed on the back of suspicious apps, the apps you will no longer find in the Google Play store. By default Android does not allow you to install apps from unknown sources so there's no chance of you accidentally installing something that harms your phone.
For iPhone users, the tech giant Apple designed theiOSplatform with security at its core. iPhones and iPads are completely safe devices unless they are beenjailbroken. Once they are jailbroken, the iOS platform couldn't limit the access of apps to the system.
So, If you are only a regular Play Store and App store user, anti-viruses are actually not recommended for you because it would just slow down your device.
