How can I find my iPhone if I don't have an iCloud account

Hello juanda,

If you're posting here you have access to iCloud through your Apple ID you are using now:

Use Find My on iCloud.com - https://support.apple.com/explore/find-my

or go directly to: https://support.apple.com/en-us/guide/icloud/locate-a-device-mmfc0f2442/icloud - Locate a device in Find My iPhone on iCloud.com - Apple Support
