AT&T prepaid brand Cricket Wireless on Wednesday announced a continuation of its retail expansion with the addition of 600 more GameStop locations.

The gaming retailer is now Cricket’s largest retail distributor with more than 3,400 locations across the country.

“We are pleased to have been Cricket’s first national distribution network and now we’re its largest,” GameStop’s senior vice president of U.S. stores Jason Cochran said.

According to Cricket, participating GameStop locations now includes a dedicated Cricket consultant in the form of a GameStop employee who has been trained to answer questions about the mobile service. The carrier said customers who visit GameStop will also be able to trade-in pre-owned video games and use the money toward their Cricket service or device.

The announcement marks the continuation of Cricket’s efforts to expand its retail presence.

In April, the prepaid carrier added more than 1,000 Best Buy stores and 2,000 Aaron’s locations to its distribution network. Back in October, Cricket also added nearly 1,600 Target stores to its retail footprint.

Cricket has been a boon for AT&T and the retail moves come as AT&T looks to maintain the momentum that helped Cricket rake in record prepaid net addition figures for the Tier-1 carrier at the end of last year.

Alongside AT&T’s other prepaid brand, GoPhone, Cricket pulled in 469,000 prepaid subscriber net adds in the fourth quarter 2015 and 1.4 million prepaid net add for the full year 2015.
