Why I Receive Error Code 1251 (Unroutable) for France RCS?

Symptom

The RCS message to the France destination is rejected with error code 1251.

Applies To

• RCS

Cause

Delivery of marketing or promotional content in France is only allowed between 8:00 a.m. and 10:00 p.m local time, Monday to Saturday. Traffic sent outside these hours will be rejected. Marketing traffic during public holidays in France will also not be delivered as per the operators' rules.

Resolution

If you sent non-marketing traffic, such as transactional or authentication, you have to set the "category" in each of your RCS API requests to the relevant value.

Please refer to the document for the Messages API reference:

• If the category value is set to "promotion" (or if this parameter is missing), messages outside the allowed timeframe will get rejected.
• For all other categories (transaction, authentication, service-request, acknowledgement), traffic will be accepted without restriction.
