Hi,
I am having repeatingly issues that my phone (Xperia xz1) "loses" it's Sim card.
It's similar to this one: "/t5/M-series/No-sim-card-error/m-p/1215106#"
My suspicion is that there is a bug while roaming from one accesspoint to an other access point while using the wifi the Sim card gets rejected by the software.
This also happens while not shaking the phone, so I expect that there is no loose connection between the sim card and the phone itself.
After a reboot the sim card is working again as expected. This happens a lot at home and almost never "outside" at other locations. (up to 2 to 10 times a day)
At home I have two accesspoints.
Is there a know issue with wifi roaming which could explain this issue?
Best regar
