The customer data exposed in the breach includes:

  • Name
  • Telephone number
  • Email address
  • SIM serial number and IMEI number (a device identifier similar to a serial number)
  • A brief description of service plan purchased

Mint says they do not store credit card numbers, so they were not exposed. The company also said they protect passwords with “strong cryptographic technology,” so they are not compromised.
