I have problem in my mobil e250 specially card memory

There are two ways to this, it's either the memory card is corrupt which is automatically bad or it isn't compatible with your phone.

use card reader

Hi, That model will only take up to a 2gb memory card.

Memory

• SMS Memory 200 SMS

• External Memory microSD™ External Memory (up to 2GB)
  

You should check your manual most probably your phone cannot work with SDHC micro SD card. The only thing you can do is buy a 2GB micro sd card.

Hi there,

I am having the same problem with my phone.
What I've found out until now is that you can only access the memory card through an USB connection or by getting a card reader. So I think this qualifies as a solution.

I am still looking for a way to make it work via bluetooth connection. I will let you know if I find anything. :)

I had the same problem and I tried everything. I couldn't think of anything else to do so I just turned my phone off and back on again. When I went back to the memory card menu on my phone all the folders that I lost re-appeared. I don't know if it would work on other phones but it's worth a try!

Go to mobile repair shop they will fix it. It is a 99% software problem and full flash will solve it.

Only reliably reads 256MB SD card or less - anything more and it gets iffy

You cannot
