Sprint Corp. is in talks again to merge with T-Mobile US Inc., Bloomberg News reported Aug. 6, citing sources familiar with the details.

The talks, which are in initial stages, come after Sprint's exclusivity window for talks with Comcast Corp. and Charter Communications Inc. ended in July.

A recent report claimed SoftBank Group Corp. has secured nearly $65 billion from four banks to place a potential takeover bid for Charter and then merge it with Sprint.
