This provision prohibits customers from participating in class action, mass action, representative, or consolidated proceedings against T-Mobile in either arbitration or court, unless they have opted out of the arbitration provision within the specified 30-day window. Customers who opt out of arbitration are not bound by the class action waiver.

This waiver prevents customers from pooling claims, which can make pursuing small-value disputes economically impractical.
The updated terms expand T-Mobile's authority to suspend or terminate service by explicitly including theft and unlawful conduct as grounds for suspension or service denial, beyond the previously stated prohibited uses. The agreement also clarifies that price commitments embedded in Rate Plans do not automatically extend to new technologies, features, or services unless expressly stated, meaning customers cannot assume their locked price applies if T-Mobile introduces new offerings. Additionally, the terms now state that reconnection or restoration of service after suspension may incur a fee. These changes modify the conditions under which service can be interrupted and the predictability of pricing as services evolve.

"ANY PROCEEDINGS, WHETHER IN ARBITRATION OR COURT, WILL BE CONDUCTED ONLY ON AN INDIVIDUAL BASIS AND NOT AS A CLASS, REPRESENTATIVE, MASS, OR CONSOLIDATED ACTIONExcerpt from T-Mobile's Terms and Conditions
REGULATORY LANDSCAPE: Class action waivers in consumer contracts are subject to ongoing scrutiny by the FTC under its unfair or deceptive practices authority. The provision's structure, which ties the class waiver exemption to the arbitration opt-out, is a notable design feature that may face challenge if the opt-out mechanism is found to be insufficiently prominent or accessible. GOVERNANCE EXPOSURE: High. The waiver applies to proceedings in both arbitration and court, which is a broader scope than waivers that apply only in arbitration. The provision that partial unenforceability of the arbitration clause does not affect the class waiver with respect to other claims creates a complex severability structure that may require case-by-case judicial assessment. JURISDICTION FLAGS: California's Private Attorneys General Act (PAGA) claims, which allow representative actions on behalf of the state, have been subject to separate enforceability analysis in California courts and the U.S. Supreme Court. The class waiver's application to PAGA or similar state representative action statutes may be subject to jurisdiction-specific limitations. CONTRACT AND VENDOR IMPLICATIONS: Business accounts that accept these terms on behalf of organizations bind all persons on the account to the class waiver. B2B contracts that incorporate these T&Cs should be reviewed to assess whether the class waiver is consistent with the organization's dispute resolution policies. COMPLIANCE CONSIDERATIONS: Legal teams should confirm that the opt-out mechanism is operationally accessible and that the 30-day deadline is clearly communicated at point of sale or activation. Organizations with high-volume T-Mobile accounts should evaluate whether centralized opt-out procedures are feasible across multiple lines.
