That is a strange occurance that your phone is not reading the memory cards. If you have tried many different cards and the same thing is happening, it does sound like a problem with the phone. We can try and transfer your information a different way. Then if you are under warranty, you can get a replacement for a hardware issue like that. What type of information were you looking to store on the card? Pictures? Videos? Let us know! You can try and message them (just like a regular picture message) to your e-mail address. Just put that e-mail in the "To" field and it will send and be charged as just a regular message according to your plan. I hope that helps and please let us know fi we can assist further!
