I am hearing that new contacts will not receive SMS because they have not gone through Mobile Connect. Adding a +1 will help them receive the message, is there a way to auto fill a +1 in a smart capture form?

    Could you explain what this +1 is or does? How are you sending the SMS? If you're sending from Journey Builder, please share what you are choosing in the "Delivery Options" configuration step in the "Confirm subscriber Opt-in section" Mar 29, 2023 at 14:40
  • +1 is the country code. If the number is not yet present in Mobile Connect it doesn't have the Locale if it has just been created as a new salesforce record. Opt in: subscribe all contacts to a keyword. They are opting in on a form then having an account created then moving through journey builder

Since it's transitioning through Core, you can create a Formula field where you add the country code based on the country. Sync this field with SFMC and create it with the Phone datatype in your DE.

Also, if the phonenumber is prefixed with the country code, there is no need to add a Locale field if you are using Journey Builder for the sendings.
