If Sprint and T-Mobile go ahead with rumored plans to merge, it appears that regulators will not greet the deal with open arms.

According to a new report from Bloomberg, Sprint executives met with Department of Justice officials to discuss a possible T-Mobile deal, but "got a cool reception."

The news service said that Softbank - which paid $20.1 billion in 2012 for a 70 percent stake in Sprint - has been speaking with T-Mobile parent company Deutsche Telekom AG in an effort to resolve any issues that might derail a deal. An actual agreement or announcement, though, could be months away.

And while Bloomberg notes that "investors and analysts have been calling for more consolidation in the industry," not everyone agrees - in particular, PCMag's lead mobile analyst, Sascha Segan. When rumors of the deal first emerged, he outlined six reasons why a deal between Sprint and T-Mobile would be a bad idea, and chief among them is their incompatible networks.

There's also the fact that T-Mobile has been doing rather well in recent months, thanks to innovative programs and outspoken CEO John Legere. T-Mobile's decision to drop contracts and become the un-carrier has prompted rivals like AT&T and even Sprint to revamp plans and offerings, which shows that competition works, Segan said.

When asked at CES about the possibility of a Sprint merger, Legere did not come right out and say he was against it, but suggested that if the companies merge, they would have to do so with T-Mobile USA in charge.

There was also talk about Dish buying T-Mobile, which Segan said would be better than Sprint, but still not ideal. For more of his thoughts on the deal, check out PCMag Live in the video below.

The last time two of the big four wireless carriers tried to merge - AT&T and T-Mobile in 2011 - it was a major fight in D.C., with AT&T eventually throwing in the towel after pushback from the FCC and Justice Department. Ironically, T-Mobile got a nice chunk of "break-up fee" change when that deal went south, enabling it to innovate and become the "un-carrier."
