D900 phone internal memory loss

first go to memory settings->default memory ->then change wap downloads or any if required to memory card ..... i have said for a samsung phone.

Check the games you have installed on your phone. Some games use up a LOT of your phone's internal memory and some have the option to save most of the data on your SD card instead of the phone's internal. Go to settings > applications > manage applications to see which ones are using the most. I would try to delete some of the games then check the internal afterwards.
If that doesnt work you could always do a full wipe of the phone's memory (wont delete the SD card memory) by going to Settings > Privacy > Factory data reset.

Memory available for this model phone is very small compared with the requirements of the Internet and wap and gprs function. Theeasiest way to solve this problem is to swap with one that is suitablefor Internet connections, preferably wi-fi.
Finally, the memory that must be emptied is the phone's internal memory (C:), but this unit is usually full of files, applications andsystems, is necessary to empty the uninstallation of applications for example.
I have helped and I find myself available for further clarifications.

Just try formatting the SD card. Hope it works fine.

Just connect the micro SD with computer.(You need SD adapter, SD card reader, and USB connection) Most computer will recognise the SD card automatically. Format the micro SD in the Window Explorer(or My Computer). Format menu can be found if you click right-button with cursor on the drive letter. After formatting, re-insert micro SD into your D900.
Some Korean experts says the problem might be caused by different file system (e.g. FAT, FAT32, etc) in each memory card. So they recommended not to share your memory card with different mobile phones as well as any electric devices (eg. MP3 player and digital camera).

how can i connect my samsung D900 to a wap

take the phone into the mobile center and ahve them fix the issue for you

Probably not enough memory in the phone, delete as many old msgs in the inbox, outbox, draft etc...
and shut down applications. To see what applications are running keep your finger on the menu for 2 seconds, press C to shut these down. Then try again if it still doesn't work, their site is probably not WAP friendly.

this may help you set up the wap settings http://uk.samsungmobile.com/supports/configurephone/wapSetting.do?&menuIdBody=00000000000016&menuIdTop=00000000000003
