Hi there, I have a 6 pin standard SIM Card Holder connected to WS6318, SIMPRES pulled up to 2V8. Yet, I continually get SIM card not inserted error. What could be the issue? I see SIM_VCC stays low. Can I workaround this issue by tying SIM_VCC to 1V8?

SIM Card Not Inserted

may be from sim-presence pin connect to 2.8 and test it
