If you're having trouble receiving SMS authentication codes from DocuSign, here are a few steps you might consider:

Addressing SMS Authentication Challenges:

1. Check the Phone Number: Make sure the phone number you provided to DocuSign is accurate. Include the right country code and avoid any extra spaces or symbols.

2. Speak to Your Mobile Carrier: Sometimes carriers block texts from automated systems like DocuSign due to security protocols. It’s worth calling your carrier to see if this is happening and if they can unblock these messages.

Considering Email Authentication as an Alternative:

If you keep running into issues with SMS, you might find it easier to use email authentication instead:

1. Reach Out to the Sender: Let the person sending the DocuSign document know you're having trouble with SMS verification. Ask them if they wouldn't mind resending the document with email verification as the method instead.

I have the same problem. I am trying to implement the Python SDK in our project. We need to send text messages with the access code to our clients so they can validate their identity before signing.

I am attaching test code based on the documentation, this is not sending me the SMS to the selected phone.

sms_authentication = RecipientSMSAuthentication(

sender_provided_numbers=="+51999999999"] # Fake Phone

)

signer = TemplateRole(

email="my-mail@gmail.com",

name="UserName",

role_name="signer",

access_code="123456",

sms_authentication=sms_authentication,

)

env = EnvelopeDefinition(

email_subject="Demo Access Code",

template_id="template-id",

status="sent",

template_roles=esigner],

)

Hello, here is a user with the same problem, regarding the first point the number was entered in the correct format "+5199999999" for a fictitious client from Peru, and it is not sending the message, maybe you could mention here if it is due to some limitation of the purchased plan, if some configuration should be enabled or something related.
About option "Speak to your mobile operator" does not make sense, we cannot ask our clients to call their mobile operator just for that, it is not friendly and even annoying.
