I am using a MMCMobile 512Mb card with my Nokia 3230 and i face the folowing problem.

I installed the card normally and the phone found it and recognized it normally. I still made a format of tha memory just in case...

Everything where seemed to work fine until i reached 30Mb used space on the memory. After that point the phone does not allow me to installa any applicasion or even tranfer any file from the pc to the phone.

After the failure of the copy a messege is appeared in the fone like that: "memory not compatible with the mobile"

I do not have and PC card reader.....

Thank you

You are not using the memory card for storage but only the phone memory from the sounds of it...? that would make sense from the limit you are seeing

When installing applications, select the memory card for installation rather than the default (phone memory).

give that a go..

Cheers
