Abstract
Methods and systems including non-transitory computer-readable storage media, for selectively erasing data stored at a wireless device are disclosed. The media includes instructions that, when executed by a processor, cause the processor to perform a method including comparing a particular service provider identified by the data stored at the wireless device to at least one favored service provider selected from a group of favored service providers consisting of a home service provider and a preferred service provider other than the home service provider. The instructions further, when executed by a processor, cause the processor to erase, if the particular service provider is not one of the favored service providers, the data stored at the wireless device.
