FeatureNotAvailable In Production 403 Forbidden

Hello, we're trying to send SMS through Ringcentral's API but we get the following error message:

Failed to send message: Client error: `POST` resulted in a `403 Forbidden` response:


"errorCode" : "FeatureNotAvailable",

"message" : "The requested feature is not available",

"errors" : [ {

"e (truncated...)

The application was previously tested in sandbox and passed all the validation requirements and is now in production. We have also registered our company's campaign with TCR and we got approved 2 days ago, but we still get that "403 forbidden" error. We are using all the production environment credentials. The phone number used for this is: 18004674112

Can you confirm if you can send text messages from that phone number from the RC app? This will quickly tell if the problem is in the number or in your code. I suspect that it is the number is not SMS enabled.

BTW, I just check the number and no number under your production account is SMS enabled. Did you request for campaign Id as well? Check the guide here.

In the Campaign tab there is already one campaign Id registered but its TCR status is "Pending". So I guess we'll have to wait until it's approved, right?
