Hi @AC,
Thanks for posting in the community.
This is the reason why Text Message Notification is not available:
If you are using SharePoint on-Prem, you can go to CA->System Settings-> E-Mail and Text Messages(SMS)-> Configure outgoing e-mail and SMS alerts.
1.Configure outgoing email:
- Install and configure the SMTP service
- set the application credential key on your servers(only if you using SharePoint Server 2019)
- Configure outgoing email for a farrm.
For more details, you can refer to the following link:
Configure outgoing email for a SharePoint Server farm - SharePoint Server | Microsoft Learn
2.Configure SMS Alert:
- Obtain the SMS Gateway by registering to any of the SMS gateway providers or Setup your own SMS Gateway.
- Import the root certificate of the service provider's Root certificate and create a trusted root authority.
- Configure Mobile account settings in SharePoint central Administration.(CA->System Settings-> E-Mail and Text Messages(SMS)-> Configure outgoing e-mail and SMS alerts.)
- Create Alerts/Use third-party applications to use the SMS alerts.
