Chosen Solution
Hey guys I have an iPhone 6 Plus I’ve been researching this for a couple of hours and couldn’t really find an exact answer. The Phone Detects the Sim comes up “Searching” then after a couple of seconds says “No Service” shows the imei in the settings dialling *#06# doesn’t show anything. I’ve updated to the latest Firmware after receiving the Phone (Bought from eBay). Now From the research I’ve done its come down to Baseband Chip or Sim Reader all the pins look intact (Hasn’t been water damaged) it also shows what Carrier I’m with in settings. I myself are leaning towards the Sim Reader but unsure or could it be just the Antenna? Any help would be hugely Appreciated. Thanks. Edit: Date and Time checked and are right.
I’ve fixed this issue by replacing the antenna switch under the bottom (stubborn) shield on the front of the board. The part is rf5159. It is definitely not a problem with the Sim tray, as it clearly detects the Sim. Since the imei appears in settings, I’d say the baseband is good. I’m not sure, but I feel as if the dialing *#06# receives the imei through the network (can anyone confirm this?) So it wouldn’t show if it wasn’t connected. If the phone has been disassembled/ reassembled immediately prior to this malfunction, ensure that each antenna connection is clearly and cleanly secured. Checking that each screw is in its place.
