Sim Card not detected Hey guys, I am having a similar issue. I have 2 Sims, AT&T and GCI (local carrier). AT&T Sim works in both Slot 1 & 2, and GCI Sim works in slot 2 only. The AT&T sim is a standard MicroSim and the GCI sim is a Tri-Cut sim, so basically a NanoSim in a Micro Adapter. Pretty sure I had the same problem until discovering in my ze551kl that there was an upper and lower slot (for lack of a better word) where the microSD is shown in that photo. In the photo, it's in the upper one. Shove it in below and I bet it works. the upper slot is an SD card slot, the lower is a sim card slot. A SIM card is needed not only for mobile communication.

I figured out the issue and the solution to the dreaded no network/no SIM card issue for the ZenFone 5Z. It is not a software problem. It is a hardware problem indeed. The new firmware basically lets the SIM card slot "work properly". If the SIM slot of your phone is defective, this issue will trigger after Pie update. zZVloO.
