This provision establishes that continued use of Twilio services after the effective date of an update constitutes binding acceptance of the new terms, and that the thirty-day notice period does not apply where updates are driven by regulatory or telecommunications carrier changes.
The updated terms establish a different dispute resolution process for customers domiciled or registered in Mexico. Previously, Mexico was subject to the standard arbitration venue clause routing disputes to San Francisco, California. Under the revised agreement, Mexican customers must first engage in good faith negotiations with Twilio's senior representatives for 30 days; if unresolved, disputes proceed to binding arbitration under Centro de Arbitraje de México (CAM) rules, conducted in English in Mexico City before a sole arbitrator. The agreement also explicitly states that Mexican consumer protection law (Ley Federal de Protección al Consumidor) does not apply to the commercial relationship between the parties. Mexico-domiciled customers should review the updated dispute resolution procedures and understand that consumer protection law carve-out before continuing use.
View change record →The updated terms establish two new regional service entities: CISA Telecomunicaciones for Mexico and Teravoz Telecom for Brazil, meaning customers in those jurisdictions will contract with the local entity rather than Twilio Inc. The agreement now permits orders to be placed through Twilio's online self-service purchasing workflow in addition to traditional written order forms, streamlining how purchase terms can be documented. The updated language also removes the prior commitment that Twilio will not materially decrease overall service functionality, replacing it with a general statement that services may change over time without specific protections on functionality levels.
View change record →The updated terms now route Twilio service agreements for Mexico and Brazil customers to new regional entities rather than Twilio Inc., which may affect service delivery, dispute resolution venue, and applicable local law. The definition of Order Form was expanded to explicitly include self-service online purchases, clarifying that terms negotiated through Twilio's account interface carry the same contractual weight as traditional executed agreements. The terms also removed language stating that Twilio would not materially decrease overall service functionality, replacing it with a simpler statement that services may change over time, which narrows the operational commitment Twilio makes regarding service stability. You can review the separate agreements that now govern your use based on your regional location.
View change record →Under this clause, customers who continue to use Twilio services after the effective date of any updated terms are bound by those updated terms as written, and material changes driven by law or telecommunications provider requirements may take effect without the thirty-day advance notice period.

"Twilio may update the terms of this Agreement from time to time. Twilio will provide you with written notice of any material updates at least thirty (30) days prior to the date the updated version of this Agreement is effective, unless such material updates result from changes in laws, regulations, or requirements from telecommunications providers. ... Following such notice, your continued use of the Services on or after the date the updated version of this Agreement is effective and binding, as indicated at the top of this Agreement, constitutes your acceptance of the updated version of this Agreement.Excerpt from Twilio's Terms of Service
(1) REGULATORY LANDSCAPE: The use of continued service use as acceptance of updated terms is a standard mechanism in SaaS and platform agreements, though its enforceability varies by jurisdiction. EU and UK law may impose additional requirements for valid modification of commercial contracts, particularly where terms change materially. The carve-out for regulatory and telecommunications-driven changes is operationally relevant given the frequency of carrier-driven changes in the communications industry. (2) GOVERNANCE EXPOSURE: Medium. The absence of a thirty-day notice period for regulatory or carrier-driven changes means customers may have limited time to assess and respond to operationally significant changes in service terms. Customers with long-lead-time compliance processes are most exposed. (3) JURISDICTION FLAGS: EU customers should assess whether the unilateral amendment mechanism and implied acceptance through continued use satisfy applicable contract modification standards under national law. Some EU jurisdictions require explicit consent for material contract modifications in commercial agreements. (4) CONTRACT AND VENDOR IMPLICATIONS: Procurement teams should establish a process to monitor Twilio's legal terms page and review any posted updates promptly upon notification. Customers should assess whether their internal approval processes can accommodate the thirty-day notice window for material changes. (5) COMPLIANCE CONSIDERATIONS: Legal teams should configure alert mechanisms for Twilio terms update notifications and establish an internal review workflow to assess material changes within the thirty-day window. Any changes affecting data processing, indemnification, or dispute resolution should be escalated for legal review prior to the effective date.
This provision establishes that continued use of Twilio services after the effective date of an update constitutes binding acceptance of the new terms, and that the thirty-day notice period does not apply where updates are driven by regulatory or telecommunications carrier changes.
Under this clause, customers who continue to use Twilio services after the effective date of any updated terms are bound by those updated terms as written, and material changes driven by law or telecommunications provider requirements may take effect without the thirty-day advance notice period.
