   We’re continuing to work with Twilio and their carrier partners to restore SMS delivery to French phone numbers on the Orange network. The carrier partners have confirmed the issue stems from a recent update to the SMS spam filter blocklist managed by a2fm. This change has unintentionally impacted multiple providers. Their technical team is actively working to reconcile the records and resolve the issue. We will continue to closely monitor their progress.

   We’re continuing to work with Twilio and the carrier Orange to restore SMS delivery to French phone numbers on the Orange network. Twilio has escalated the issue directly to Orange, and we’re pressing for an urgent resolution. We don’t yet have an estimated time for a fix. In the meantime, affected users can configure some notifications to be sent over other channels such as email or push. Alternatively, users can enable text messages over WhatsApp as a temporary workaround to keep receiving text messages for 2FA codes, card authorizations, and other account notifications. Both options are available in your Brex profile's notification settings.
