About the SIM reset, I was one of the least affected, but it got worse this week.
My problem was very light, only saw it once a week lately (or less);
But I've acquired a data card for SIM2, and since that I have the SIM reset sometimes 4 or 5 times a day...
When it happens, it asks both SIMs' pins.
Tried setting the PIN to Off on that SIM2 only, but it did't help, it still happens (it then asks for the PIN on the SIM1 only).
I think it started to happen more frequently because this network is a lot weaker then my main one, I can see it losing network signal frequently (and almost always it asks for pin immediately).
