Leap Wireless International and MetroPCS Communications today entered a national roaming agreement, formed a separate agreement to exchange wireless spectrum and settled all outstanding litigation between the companies.

The new roaming deal lasts for 10 years, covers existing and future markets and could be extended in the future, both companies said.

In the spectrum swap, Leap acquired 10 MHz in Fresno, Calif.; San Diego; Seattle and other northwest markets, while MetroPCS acquired 10 MHz in Dallas-Ft. Worth, Lakeland-Winter Haven, Fla., Shreveport-Bossier City, La., and various Texas markets. FCC approval is needed for the swap, but that is formality.

All litigation between the companies is now dropped, but Leap nor MetroPCS disclosed details or financial terms of the agreement.

Leap last year rejected MetroPCS’s $4.7 billion acquisition offer.
