Dish Network had warned that foreign ownership of Sprint would lead to a threat to national security. Both SoftBank and Sprint agreed last month to a host of conditions revolving around national security in order to get the deal approved. Sprint will have a four-member national-security committee with a security-director that would sit on Sprint's board. Members of the committee would have to be approved by the government, which would get veto rights over Sprint's equipment purchases. The deal would also force the carrier to remove some equipment on Sprint's pipeline that was purchased from China.
With SoftBank's deep pockets, Sprint hopes to be able to grow in size enough to challenge Verizon and AT&T in the states. Currently, Verizon is the largest mobile carrier in the U.S.
