The memory card should never be simply removed from a system during normal operation. Doing so can cause the corruption of files in use. Either the memory card or the whole system must be shutdown before removing a memory card.

While the card is shutdown, voicemail is not available to the system. Any other services that use the memory card are also disabled. Features licensed by the System SD card continue for up to 2 hours while the card is not present.

Once a memory card has been removed, reinserting the memory card automatically restarts it.
