Can a reminder be sent via SMS text? on a set date?

We'd like to set up a SMS text reminder for anyone who has registered for an event (and chosen to be reminded via text by supplying their mobile number on the form). That SMS reminder would be sent on a given date. We'd like for the recipient to hit 'C' (or something like that) to Confirm, or 'R' to request a follow up...etc.

I'm looking into the Zapier interface - but believe I also need to identify the SMS app. Amy suggestions?

Thanks!

There are 3 methods to achieve that.

1. That's possible if your mobile network provider supports SMS gateway. Simply find your SMS email gateway on the following list: http://en.wikipedia.org/wiki/List_of_SMS_gateways

Then, construct your email address using the following format. 

number@serviceProvider.com 

Replacing the number with your mobile number and the serviceProvider with your provider's SMS gateway domain. Example for AT&T:

Format: 10-digit cell phone number@txt.att.net

Example: 3335551111@txt.att.net

After that, set the constructed email as your form's notification email recipient. Guide: https://www.jotform.com/help/41-Finding-out-E-mail-Address-used-for-submission-notifications. Then 

2. Through 3rd party SMS apps that can be integrated at Zapier.

Example: https://zapier.com/apps/jotform/integrations/sms

3. Through Webhook but this requires API from your SMS Provider and a custom PHP script that would send the message after submission. 

You can find an example SMS Notification for Webhook here https://www.jotform.com/help/248-Webhook-PHP-Script-Examples (Check example no. 2 on this guide) 

I'm thinking this is incoming SMS approaches? I'm trying to SEND SMS reminders to anyone who has submitted a form (sending to their mobile number collected within the form).

I am not sure if this is possible. My colleague provided a guide for notification alert only and not for an autoresponder alert via SMS.

You can try using Twilio to send SMS messages via email to send responders to users. For more information, please check this link: https://zapier.com/apps/jotform/integrations/twilio
