Hello @Arif
We have tested a few months ago all of the gateways that are available with the SMS Notification extension. I’m not sure why you are facing the error though 🙁
However, we recommend using Twilio if possible. We have complete documentation on this-> https://wperp.com/docs/crm-add-ons/sms-notification/
Also, if you get any error on the console or something, please feel free to get in touch with our support team. You can email them to [email protected]
Thanks
