E900 supports up to 2GB memory card, and now listen: SanDisc ONLY. In real it means, that possibly you can use some cheap 128MB MMC, but Samsung can't guarantee, that this will work. With SanDisk Samsung guarantees, that it will work with storage up to 2GB. Sometimes happends, that phone can use 1GB MMC Sandisk, but no 1GB other brand. Hopefully I hepled you. Take care, mate Level4 tech.
Hi May be the card is with big capacity and the phone is not recognize look you phnoe manual and see the max capacity of your phone support.Or may be the card is not working properly. Good luck.
