RULETwilio requires privacy policy and T&C URLs for new A2P 10DLC campaign registrations2026-06-30›

Starting June 30, 2026, Twilio's Messaging REST API rejects new A2P 10DLC campaign registrations that omit PrivacyPolicyUrl or TermsAndConditionsUrl fields. Both must be valid, publicly accessible URLs. Only new campaign submissions are affected; all previously registered campaigns continue unchanged. The change applies to POST /v1/Services/{MessagingServiceSid}/Compliance/Usa2p, and Twilio notes campaigns including these URLs pass carrier review at higher first-submission rates.

POLICYAT&T raises A2P SMS +$0.0005/msg (~17%) and MMS +$0.0015/msg (~20%) across all routes2026-04-01›

AT&T increased A2P pass-through fees effective April 1, 2026, reflected on May 2026 invoices. SMS MT and MO rates rose $0.0005 per message (~16.7% increase); MMS MT and MO rates rose $0.0015 per message (~20% increase). Increases apply uniformly across 10DLC, standard-rated short code, and toll-free messaging channels. This follows similar fee hikes from T-Mobile and US Cellular that took effect January 19, 2026.

POLICYT-Mobile and US Cellular raised US A2P SMS carrier fees2026-01-19›

Effective 19 January 2026, T-Mobile increased outbound A2P SMS carrier pass-through fees across long code, toll-free and short code, and US Cellular applied its own A2P pass-through fee updates the same day. These are carrier surcharges added on top of a provider's listed per-message rate, so they raise real US delivery cost without changing headline prices. Source ↗ · US comparison →

POLICYUS A2P 10DLC registration fees increased (TCR, August 2025)2025-08-01›

In August 2025 several Campaign Registry (TCR) charges for US A2P 10DLC rose, including brand registration, standard brand vetting and campaign verification fees. These one-time and monthly registration costs are separate from per-message carrier surcharges and must be paid before US A2P SMS can be sent. Source ↗ · US comparison →
