The HTC EVO 4G comes with an 8-GB micro SD memory card pre-installed in the phone. If you need a memory card with more room, you can remove the EVO 4G's pre-installed card and replace it with a higher-capacity memory card. The EVO 4G supports micro SD cards up to 32 GB. The phone also has 1 GB of internal memory, so you can get by without a memory card if necessary.
