T-Mobile’s marketing pitches are working.

A new study conducted by Consumer Intelligence Research Partners (CIRP) released today found that T-Mobile “dominated” the first quarter of 2016.

CIRP, which polled 500 U.S. customers who activated a phone from Jan. 1 to March 31, found that T-Mobile attracted the most new phone activations from customers who were previously with a competing service.

“Once again, T-Mobile showed it can attract significant numbers of new customers, while retaining its current ones,” Josh Lowitz, partner and co-founder of CIRP, said in a statement. “It attracted new customers from other carriers at an astonishing rate, attracting another 42 percent of their base of existing customers who activated a phone in the quarter.”

CIRP also noted that Sprint similarly grew its base by 30 percent from other carriers’ existing mobile phone owners, but said that Sprint lost just as many customers.

“Verizon and AT&T had smaller competitor customer attraction rates, at 14% and 10%, respectively,” CIRP added.

T-Mobile, the nation’s third-largest carrier behind Verizon and AT&T, has continued to push forward with its “Un-carrier” marketing campaigns that have resulted in rapid growth for the Bellevue, Wash.-based wireless company. The company also just opened the new T-Mobile Arena in Las Vegas while offering new perks for customers like MLB game streaming and additions to its “Binge On” video streaming program.
