In a letter to Trump Mobile dated today, Sen. Hassan raised multiple regulatory concerns. She wrote that the company appeared not to have secured authorisation from the Federal Communications Commission (FCC) to operate the international calling portion of its phone service. The letter also alleged that Trump Mobile did not file a required robocall mitigation plan. Its key business partner, Liberty Mobile Wireless, made a filing with the FCC's robocall database, but it was incomplete, Hassan said.
Hassan's letter further questioned the company's security practices after a recent report that hackers stole personal data of 3,615 Trump Mobile customers. The company had previously confirmed that a vendor it used exposed customers' personal data, including phone numbers and home addresses, on the Internet. Hassan alleged that Trump Mobile failed to follow multiple FCC filing rules designed to help ensure the security of mobile services.
The senator's letter did not specify what immediate consequences Trump Mobile might face, but it adds to growing scrutiny of the mobile virtual network operator's compliance with federal telecommunications regulations.
