Adobe SIgn: Mobile SMS to sign not received

[innovative_code5E6B]

Hi

In our company, when trying to sign a PDF and using the mobile method (Use your mobile device to easily draw or capture your signature. A link will be sent to you mobile device via text) an SMS is only received 1 out of 10 (or more) tries on the Belgian Proximus network. When I try this on another mobile network (Telenet) it works every time.

When using a Telenet number (which is working every time) the sender's number is always a short number (like 8128).

On the Proximus network (that only works once out of 10) the sender's number is +447873077777.

I reached out to Proximus and they told us it might be a problem with the used SMS Route.

Do you have an ideae what could wause this?

Kind regards

Hi Bert5E6B,

Thank you for reaching out, and sorry about the delay in response.

Please confirm if you still experience similar behavior.

If yes, would you mind sharing the screen recording of the workflow?

We have checked your account with the email address used to sign in here on the community board.

Acrobat Sign account shows as free. Let us know if you are using the service with an alternate email address or have recently changed your email address for the Adobe account.

Thanks,

Meenakshi

Same situation here; I regularly receive documents from a US company for approval via Adobe Sign. The required SMS confirmation codes sometimes come through, sometimes they don't. I'm also using Proximus as mobile phone operator.

Strange issue and no solution (or an answer) until now.
