Sprint announced it has expanded its Wi-Fi hotspot coverage through several new partnerships.

The Sprint PCS Wi-Fi Access service now sports 19,000 wireless LAN hotspots, up 5,000 from March. The carrier has signed roaming agreements with four ISPs and virtual network providers to beef up its Wi-Fi network. The new service providers are London-based Quiconnect, Fiberlink Communications, Opti-Fi, Pronto Networks and Nomadix.

Quiconnect provides access to about 6,000 international locations, but the carrier expects that number to grow throughout the year. Part of that growth will include wireless LAN access in 30 international airports.

Sprint will use about 3,800 Wi-Fi hotspots from Fiberlink, about 30 Wi-Fi hotspots in airports around the U.S. from Opti-Fi, “hundreds” of hotspots from Pronto and 350 hotspots from Nomadix.

Sprint also says it plans to expand its total number of Wi-Fi hotspots to 25,000 by year-end.

Customers of Sprint’s Extended Workplace service can use any of Sprint’s hotspots around the globe to access their corporate network. Sprint announced the service last month.

At 19,000, Sprint has nearly as many Wi-Fi hotspots as competitors AT&T and MCI combined. AT&T says it has just over 9,000, and MCI says it has just over 5,000.
