Hours after the high-profile launch of Trump Mobile, a new Trump-branded mobile service provider, in June, callers to the company’s customer support line were greeted with, “Omega Auto Care, how can I help you?”

Two calls placed by Reuters that day to the mobile service’s helpline rang to the Missouri-based auto-warranty company, which is part of Ensurety Ventures, a St. Louis, Missouri firm led by entrepreneur Pat O’Brien, who was introduced by Eric Trump and Donald Trump Jr. on June 16 as a member of the launch team providing “customer support and device protection” for Trump Mobile.
