I recently purchased (on ebay) one of those "newest" dual twin
SIM card adapters . Unfortunately I cannot make any use out of this adapter. I have a Samsung SGH T309 T- Mobile cell phone. I believe I installed the adapter properly. I placed the original
sim card on the
sim-1 side and together slid them back into the original
sim card slot on the phone. The new
sim card I put by means of the metal clip onto the
sim-2 side of the adaptor. When I power up the phone the ONLY information I get is at the home page - it says "
SIM-1". The ad said, "Easy to switch between numbers online with an easy user Menu created by your phone menu system when put into the dual
sim card adapter" Unfortunately I get no such menu. The phone will not switch to
sim-2 even if I shut it off and then turn it on. Furthermore, when someone calls the phone # on
sim-2 the phone does absolutely nothing. They get voicemail, but I have no way of knowing that someone tried to call. Can you help me?
