T-Mobile and Sprint are the nation's third- and fourth-largest wireless providers respectively. Combined, the two will have 127 million customers.

SoftBank owns 85 percent of Sprint. Deutsche Telekom owns about 60 percent of T-Mobile, and it will consolidate the combined entity's earnings.

Verizon has more than 150 million wireless customers. AT&T reported 144 million subscribers at the end of the last quarter.

The deal is not guaranteed to succeed. The U.S. government still has to approve the deal, with international agencies likely to weigh in as well. But, even if the deal falls through because of regulatory concerns, Sprint consumers will be allowed to use T-Mobile's network.
