Sim card Socket :
On some older DM800HD boxes, the suppliers used some glue to
block the old sim 1.0 card. To replace the old sim, you will need to
remove carefully the sim and the old socket cutting it in small pieces.
Then once the motherboard cleaned, you will be able to solder the
new socket available here, to get the freedom of your new box with
the powerful new sim, that will open you the horizons of the OE2.0
as well as the IPTV Plugins/Applications.
