Digital Joy supports voting with SMS as part of One-time, SMS+Interactivity Suite, and Educational Plans.
To vote by SMS, your audience needs to text the option or the sequential number of the option to the phone number of your account.
Here's an example poll.
Do you accept civil marriage?
Now, to vote for the second option someone can text either "No" or "2", both will be counted as a vote.
Please note that in case the voter chooses to send the option itself, it has to match your poll's option exactly. Any typos or additional characters will make it an invalid vote.
SMS voting will be disabled for your account if you do not renew after your plan expires.
