You can customize your page and make it public by using the link provided on the Dashboard, however please keep in mind that if you use SnapCall Free, you can only receive a maximum of 10 media from your customers.
When you reach such limitation, you then need to cancel one or more of the media you previously received from your clients.
You can also try the feature for free for 14 days, in that case there is no limit whatsoever.
