AT&T Inc.Named defendant in VoIP-Pal's amended antitrust suit alleging unlawful tying, monopolization, and predatory pricing over Wi-Fi calling.
VoIP-Pal.com Inc. has filed its Third Amended Complaint in its federal antitrust action against AT&T Inc., Verizon Communications Inc., and T-Mobile US, Inc., in the United States District Court for the District of Columbia. The amended pleading, filed on September 4, 2026, follows a court ruling that allowed the company to streamline its claims. It asserts four causes of action under the Sherman Act, including unlawful tying, unreasonable restraint of trade, monopolization, and predatory pricing, alleging that the carriers condition access to Wi-Fi calling on the purchase of their retail cellular plans, thereby foreclosing the market for standalone Wi-Fi calling. CEO Emil Malak discussed the case in a CEOCFO Magazine article published today, expressing satisfaction with the revised complaint.
