30910: Campaign rejected: A2P 10DLC campaigns must be submitted in English

Twilio rejects your A2P 10DLC campaign when campaign registration fields include non-English content. Submit the campaign description, message_flow, sample messages, and related registration details in English so reviewers can verify your use case and consent flow.

• The campaign description includes text in a language other than English.
• The message_flow field includes non-English opt-in details or disclosures without an English translation for review. (help.twilio.com)
• One or more sample messages are written in another language without an English translation.
• Registration fields contain mixed-language content that does not clearly describe the campaign for verification.

• Rewrite all campaign registration fields in English before you resubmit the campaign.
• If your end-user disclosures or message samples are presented in another language, include an English translation in the registration details and in message_flow for verification. (help.twilio.com)
• Make sure your sample messages match the registered use case, identify the brand, and include required opt-out language where applicable.
• Review the campaign details requirements, update the rejected fields, and then resubmit the campaign for review.
