Multiple carrier partition dynamic access on a mobile device

A mobile communication device, comprising:

• a radio transceiver;
• a non-transitory memory, wherein the non-transitory memory is apportioned into a plurality of partitions that includes at least a system partition, a user partition, and a carrier partition having a first carrier sub-partition and a second carrier sub-partition, wherein the first carrier sub-partition is configured to store a first carrier identity specifying configuration information that enables the mobile communication device to access a first communications network, and wherein the second carrier sub-partition is configured to store a second carrier identity;
• a processor;
• and
• an application stored in the non-transitory memory that, when executed by the processor, is configured to:
• determine that no carrier identity exists in the second carrier sub-partition,
• based on the determination, download and store the second carrier identity in the second carrier sub-partition separate from the first carrier identity,
• detect a triggering event,
• in response to detecting the triggering event:
• change from the first carrier identity in the first carrier sub-partition to the second carrier identity stored separately in the second carrier sub-partition of the non-transitory memory, wherein the first and second carrier identities are maintained and the first and second carrier sub-partitions are protected from alteration during a system reset of the mobile communication device, and
• apply a user experience element associated with the second carrier identity, wherein an operating system of the mobile communication device restricts write access to the system partition based on an original equipment manufacturer (OEM) access password and restricts write access to each carrier partition based on a wireless communication service carrier access password.
