Do you have or recommend any third party solutions for sms verification?

I want to be able to send users a SMS text verification after they submit form. Some solution that will be automatically generated once form is submitted. Example. Someone fills out form that also requires phone number. Then a confirmation text is sent to their mobile phone with a code that they have to return to our site to enter the code.

I believe that can be achieved by using webhooks for your forms. Simply follow this guide provided by my colleague here: We want to send a SMS to our Visitors when a Form is Submitted. You may need to hire a developer to set this up, however, once it is setup you should be able to send an sms to your users after submission. If you need further assistance, please let us know.
