My Pixel 4a seems to be not recognising my SIM. It switches to Emergency Calls Only about a dozen times a day.
Especially when I haven't used the phone for a little while.
I either have to reboot the device or fiddle around with adding a SIM card which goes through a process of downloading a SIM and before it recognises my physical SIM.
I have fiddled around with piles of settings wondering if some kind of battery optimization was disabling it. I even activated a brand new SIM this morning and the issue persists.
I have almost resolved to the fact it is most likely the device itself is faulty, but I am holding out hope there is some kind of DIY fix I am missing. I was on the phone with Koodo support this morning and the call dropped because of this. I am trying out Wifi calling now, and perhaps will try having support call me again but if anyone has any insight or experience it would be extremely helpful
