T-Mobile Money accounts and digital banking services are provided directly by Coastal Community Bank, which acts as the official FDIC-insured issuing institution. T-Mobile itself operates as a telecommunications and wireless network provider rather than a chartered financial institution, partnering with Coastal Community Bank to offer mobile-first checking features, interest earnings, and fee-free transaction tools. The T-Mobile Money Debit Mastercard is issued by Coastal Community Bank pursuant to a direct licensing agreement with Mastercard International Incorporated. This partnership ensures that consumer deposits held through the mobile platform receive official pass-through federal deposit insurance up to applicable regulatory limits while leveraging modern telecommunications software.
