I have a Cect P810 Mobile from China and have a problem with the phone seeing a new memory card i put in.

The phone came with a 128b card that the phone see's but when i put a 512mb card in it does not see it but when i plug the phone into the USB port it see's it.

I have FAT formatted the card through the USB port and the phone still does not see it also i have FAT formatted it on the PC but still the same problem.

I have tried bigger and smaller cards but it still does not see it.

Is there something on the phone i need to do as well?

Regards
