Everything is perfect Original device, never repaired, strong battery, loud speaker. Relax is so good. -MDM (Mobile Device Management): Essentially, this refers to a scenario where a company purchases iPhones directly from Apple and installs mdm software (distinct from iCloud) for use by its employees. After approximately one year, the company retrieves these devices and replaces them with newer iPhone models. We acquire these batches of corporate-owned iPhones, perform a factory reset, and bypass the management software.\

• Once the iPhone mdm is bypassed, the iPhone functions and operates completely normally. Simply insert a SIM card, sign in with your Apple ID, and start using it.
