7. The non-transitory computer readable storage medium of claim 6 , wherein: the device profile comprises subscriber identity module (SIM) data that defines the new unique IMSI, the new unique IMSI comprising a mobile country code (MCC), a mobile network code (MNC) and a mobile station identification number (MSIN) associated with the second wireless carrier; and the SIM data further defines settings for the second wireless carrier, the settings comprising at least one of security authentication information, ciphering information or a list of services.

8. The non-transitory computer readable storage medium of claim 7 , wherein the device profile further comprises a modem profile that defines connection parameters for the second wireless carrier, the connection parameters comprising at least one of a frequency band or a format for presenting a name of the second wireless carrier on the user device.

9. The non-transitory computer readable storage medium of claim 6 , wherein obtaining the device profile associated with the second wireless carrier comprises at least one of a) receiving the device profile associated with the second wireless carrier from a server or b) retrieving the device profile associated with the second wireless carrier from secure memory.

10. The non-transitory computer readable storage medium of claim 6 , wherein the receiving comprises receiving the indication in response to a condition associated with the switch from the first wireless carrier to the second wireless carrier, wherein the condition is any one of a change in a location of the user device, a message indicating that the user device is denied network access via the first wireless carrier or a change in a network access performance characteristic.

11. The non-transitory computer readable storage medium of claim 6 , wherein receiving the indication that the switch of the user device from the first wireless carrier to the second wireless carrier is to be performed comprises at least one of a) detecting that a condition pertaining to the switch of the user device from the first wireless carrier to the second wireless carrier has been satisfied or b) receiving a command to perform the switch from the first wireless carrier to the second wireless carrier.

12. A user device comprising: a wireless modem; and a processing unit coupled to the wireless modem, the processing unit to: receive, while the user device is connected to a first wireless carrier, a message comprising an indication that a switch of the user device from the first wireless carrier to a second wireless carrier is to be performed; send a response to the message, the response indicating that the switch to the second wireless carrier is undesirable; in response to the sending the response to the message, receive a second message indicating a switch to an alternative wireless carrier when a rule provides the alternative wireless carrier for switching; and receive a third message insisting that the switch to the second wireless carrier be performed when no rules provide the alternative wireless carrier for switching; when no rules provide the alternative wireless carrier for switching, obtain a device profile associated with the second wireless carrier, the device profile comprising data defining a new unique international mobile subscriber identity (IMSI) associated with the second wireless carrier that will replace a current IMSI associated with the first wireless carrier; reprogram the wireless modem using the device profile associated with the second wireless carrier, wherein the reprogramming causes the user device to switch from the first wireless carrier to the second wireless carrier; and establish a network connection for the user device using the device profile associated with the second wireless carrier.
