JotForm is a free online form builder which helps you create online forms without writing a single line of code. No sign-up required.
We believe that if one user has a question, there could be more users who may have the same question. This is why many of our support forum threads are public and available to be searched and viewed. If you’d like help immediately, feel free to search for a similar question, or submit your question or concern.
Unfortunately we do not have built in feature to send SMS notifications but with a little workaround it is possible to achieve your requirement.
You can use your our own service provider's API to send submission SMS and there are multiple ways available to do this:
#1. You can setup custom PHP thank you page in your form where you can read the submission data and send it in SMS by taking advantage of your SMS api. The following guide should help you: http://www.jotform.com/help/213-Send-POST-Data-From-JotForm-Using-PHP-in-Custom-Thank-You-Page
#2. You can also setup webhooks to send POST data which will send submission emails: http://www.jotform.com/help/245-How-to-Setup-Webhook-with-JotForm
Hope this helps.
Do get back to us if you have any questions.
