Sim event can't receive


I use Q2687g for my project. My application has Dual SIMs. SDK is 2.34, Firmware is R744; I switch the two SIMs(Two differernt Operators) using GPIOs, I find that when I switch the two SIMs for a long time(about 200 times), the SIM events (ADL_SIM_EVENT_INSERT, ADL_SIM_EVENT_REMOVED) can not receive. but using the two same operator’s SIM card, the test will be better. hope your help.


Are you using OSA(Open Sim Access) Feature??
I guess for your query you can get in touch with the Sierra Wireless Support through your distributor.
