Dallas-based network provider AT&T Inc.’s $39 billion acquisition of T-Mobile USA Inc. will have to face a coordinated antitrust review by the Federal Communications Commission and the US Department of Justice, emerging reports claim.

According to reports, a U. S. official, an assistant at the Federal Communications Commission informed on the condition of anonymity that

The Federal Communications Commission and the US Department of Justice will coordinate their antitrust examinations of the potential deal, and will work together to reach a decision.

But, the Federal Communications Commission and the US Department of Justice are not the only hurdles that the proposed AT&T/T-Mobile deal will need to clear. The US Congress will also examine the deal.

It was on March 20, when the second-largest carrier AT&T tabled an offer to purchase Deutsche Telekom AG’s T-Mobile USA Inc., which is the fourth-largest network provider in the country.

However, AT&T is yet to file its application at the FCC. According to a spokesperson for the company, the application will be filed around April 21.

Meanwhile, Sprint Nextel Corp.’s CEO Dan Hesse opposed the AT&T/T-Mobile merger, arguing it would restrict competition and hurt consumers.

In case the deal gets clearance, the merger will create a new market leader, larger than Verizon Wireless.
