WHEN I WAS IN THE U.S. ARMY FROM 1966 THRU 1968, I WAS IN A UNIT KNOWN AS "EGSM" IN Germany. IT STOOD FOR "EQUIPMENT GENERAL SUPPORT MAINTENENCE", WHICH IS WHAT WE DID. EGSM stands for Extended Global System for Mobile communication . This is introduced to enhance the capacity of the network, i.e., to accomodate more number of mobile subscribers .
This is actually the EGSM uplink band. It carries signals "up" from the mobile station to the base station. EGSM downlink is from 925MHz to 960MHz and carries signals from the base station "down" to the mobile station.
GSM, or Global System for Mobiles , are a standard set of frequencies where hand held devices such as cellular phones can work on. For a typical tri-band device, the range of frequencies it will be compatible with are GSM900Mhz, GSM1800Mhz,and GSM1900Mhz. At some point in time, a range of extra spectrum was added to the 900 band and the EGSM900Mhz was born with E to mean Extended. EGSM900Mhz is used everywhere around the world except for the United States and Canada.

To answer you question, it is impossible to do so.The only way to run Java games on this type of Samsung cell phone you have to download it through the WAP and understandably it is not free.However, there is a way to install Java games on E250 for free but this method is somehow illegal and so i will not provide anymore information.A hint to do so: Search on Google - How to install games on Samsung E250 for free. Or so.You can used your bluetooth1) Download SoftickPPP and Samsung Java Uploader.exe from here. Also JADmaker if required.SoftickPPP download here!!http://www.4shared.com/get/47700057/...FBAB96A72.dc82Uploader.exe http://software.techrepublic.com.com...3&promo=110000Uploader.exe for Samsung http://www.2shared.com/file/1837254/..._Uploader.HTMLJADMaker http://software.techrepublic.com.com...3&promo=1100002) Install SoftickPPP according to this Polish website. I don't understand Polish, but the pictures tell enough of the story. Set up your bluetooth COM ports in the SoftickPPP bluetooth/serial settings. My Bluetooth COM ports are either 24, 25 or 26. I leave them all ticked.3) Enter *#52828378# on the phone to access the Java Test Menu. Choose OTA type setting, choose Serial bearer OTA. Click select. (This seems to need to be changed back to GPRS bearer OTA for Samsung PC Studio to connect)4) Start SoftickPPP. Click on cancel for the missing USBPort.dll error message. Accept bluetooth connections for DUN and Serial connections on the phone.5) Choose 'Activate PPP' by right clicking on the icon in the taskbar. Accept connections on phone again.6) Start 'Uploader.exe' and then add the required jad file. Leave the program open.7) If you are not still in the Java Test Menu then enter *#52828378# on the phone again. Select 'Serial test', 'PPP Up', 'Bluetooth' on phone, 'Serial download'. My phone sometimes restarts at this point in which case I have to choose 'Shutdown PPP" in the taskbar icon and then re-activating it once the phone has restarted and then re-do step 7 after entering the Java Test Menu again.A Java splash screen should appear with a progress bar showing the upload of the file. The game then starts automatically.There we go.
