The report claims that Sprint is looking into any regulatory concerns that may arise. The carrier could launch a bid worth more than $20 billion sometime in the first half of 2014. The size of the bid would depend on the stake Sprint wants to buy in T-Mobile.
Such a merger may face strong antitrust opposition as in the AT&T attempt to buy T-Mobile in 2011.
Sprint stock is up 3.68% to $8.74 in after hours trading.
