Hi there.
I am a bit confused about collecting consent for SMS which I will describe below.
I have a form that confirms opt-in for SMS that only shows up on a mobile. This is easy to configure because of the special "Subscribe via SMS" action button that you can put in mobile only forms. So people click that button on their mobile, they get sent a text message asking them to "Join" the list.
That problem I have is this...
I have the same setup on a desktop. I have the same sort of form but it only shows on desktop. People have to manually type in their phone number to sign up for SMS and press "Send me texts".
But I don't know how to get their consent for the list it sends them to this way. I've tested it with myself and nothing happens asking me to confirm my sign up on my phone. If the list they are configured to join has "double opt-in" checked or "single opt-in" checked, they just join the list anyway. So it appears to not matter if I have double or single opt-in checked.
I hope I explained that clearly enough. I'd appreciate any help.
Thanks!
