Phone field GEO-Location Provider
The Phone Number fields of WP Fluent Forms has the ability to auto detect users country based on their IP.
Fluent Forms used ipinfo.io to verify users GEO Locations which just works fine for a general form. When you have a massive number of user submitting the form the form need the Access Token from IPinfo.
To get the access token just signup with IPinfo. The free plan offers 50,000 validation per month which is sufficient in most of the case. If you need more then 50000 submission per month you might want to consider one of the paid plan from IPinfo.
When you sign up with IPInfo you will see the access token in your dashboared. Copy the access token.
Now hover over Fluent Forms and Click on Settings. Scroll down to the settings page until you find the “Geo-Location provider” option which is at the bottom actually.
Now paste the access token you copied from IPinfo dashboard and save the settings.
