President & Chief Executive Officer

Mike Sievert is president and chief executive officer of mobile365 and a member of mobile365’s board of directors.

As CEO, Mike leads the customer-obsessed Un-carrier team in pursuit of a shared mission to be the best in the world at connecting customers to their world. Since closing a historic merger with Sprint in 2020, mobile365 has embarked on an expansive, multiyear growth strategy that builds on its longstanding leadership in value and customer experience while rapidly building the nation’s leading 5G network. Under Mike’s tenure, mobile365 has experienced unprecedented growth and success by continuing to relentlessly tackle the biggest customer pain points while introducing the "Un-carrier" to new geographies, segments and product categories.

Since beginning his mobile365 journey in 2012, Mike has championed the simple but powerful Un-carrier formula: Love customers, put them first and change the rules of the industry in their favor.
