Use the Google Maps plugin instead
As of February 2021, the Smart Map plugin has been replaced by the Google Maps plugin for Craft CMS.
After evolving as Smart Map for seven years, this plugin has been renamed to Google Maps. It has been completely, 100% refactored from the ground up, improving upon every single aspect of the original plugin.
The new Google Maps plugin is better, faster, and easier to use. It does everything that Smart Map did and much, much more! And it's backed by detailed documentation which explains every single feature in depth.
