Your mobile information will not be sold or shared with third parties for promotional or marketing purposes.

So something to that effect is the bare minimum accepted by carriers.

Also, ideally the carriers like to see a more robust sharing verbiage such as: All the above categories exclude text messaging originator optin data and consent; this information will not be shared with any third parties.

We will not share your opt-in to an SMS campaign with any third party for purposes unrelated to providing you with the services of that campaign. We may share your Personal Data, including your SMS opt-in or consent status, with third parties that help us provide our messaging services, including but not limited to platform providers, phone companies, and any other vendors who assist us in the delivery of text messages.
