Sprint is in exclusive talks with Charter Communications and Comcast on a potential deal for the cable companies to offer wireless services on the carrier’s network, CNBC has confirmed.

The Wall Street Journal reported on the talks late Monday, citing people familiar with the matter.

The deal for exclusive talks through late July puts Sprint’s merger talks with T-Mobile US on hold. The cable companies could take an equity stake in Sprint.

The talks could include the possibility of the cable companies jointly buying Sprint.

A Comcast spokesperson declined to comment.

Sprint and Charter declined to comment when contacted by CNBC.

T-Mobile US didn’t immediately return CNBC’s emailed requests for comment, which were sent outside office hours.

Disclosure: Comcast is the owner of NBCUniversal, the parent company of CNBC and CNBC.com.
