MADRID (Reuters) - Spanish broadband operator Jazztel said on Monday it was in exclusive talks to offer mobile phone services via France Telecom's Orange unit.

"The agreement ... aims to launch Jazztel's mobile services in the coming months," Jazztel said without adding details.

Virtual operators buy excess network capacity from existing mobile operators to offer their own services, usually at lower rates as they don't bear the hefty costs of building and maintaining their own networks.
