Verizon Communications Inc., the largest U.S. wireless carrier, informed employees Wednesday that its wireless operations will be reorganized and that there will be an unspecified number of job cuts.

The company’s 20 regional offices will be reduced to six, Verizon spokesman Jim Gerace said Wednesday. He said some jobs will be eliminated though declined to say how many. Sales and store employees won’t be affected, he said.

Verizon, which had a workforce of 177,900 as of the end of the third quarter, is seeking to cut costs as U.S. households give up their traditional home phones in favor of mobile technology.

The company gets about 29 percent of its revenue from landlines, and is investing in wireless and Internet-delivered content. Last month Verizon introduced go90, a free mobile video service with shows aimed at teens. In 2000, landline operations accounted for 67 percent of revenue.
