Boingo Wireless Inc. on Wednesday said that NTT Docomo Inc., the second largest mobile operator in Asia, was expanding its relationship with the Los Angeles Wi-Fi hotspot provider.

Boingo’s Asia Pacific subscribers use Tokyo-based NTT’s network of 55,000 hotspots they travel in Japan. Under the new agreement, NTT customers will access Boingo’s global network of 600,000 hotspots when they are traveling abroad, thus reducing roaming costs for NTT subscribers. Boingo also will provide other telecom services to NTT.

“As the cost of global data roaming has become an increasing pain point for carriers, our Wi-Fi platform will give them a remedy to ease that pain for customers,” Allen Pan, Boingo’s director of Asia Pacific, said in a statement.

Financial terms of the partnership were not disclosed.

Boingo shares closed up 4 cents, or less than 1 percent, to $7.01 on the Nasdaq.
