‘Literally truthful’ claims — T-Mobile US responds to Verizon lawsuit

T-Mobile US has formally pushed back on Verizon’s lawsuit over its advertising, calling the rival carrier hypocritical and defending its savings claims as "literally truthful." Verizon sued earlier, arguing that T-Mobile’s promise that customers can save more than $1,000 a year by switching is "mathematical fiction" and misleads consumers.

In its response, T-Mobile points at Verizon’s own "Switch to Verizon" marketing as using similar comparative tactics and says its savings figures come from real-world plan comparisons, not made-up numbers. The dispute centers on how both operators frame cost differences in their national ads, and whether those claims accurately reflect what most customers actually pay.
