I bought a new A40 at the beginning of March, along with a new IDMobile SIM.
The phone worked fine for several weeks, but now regularly displays the error “SIM Card not inserted”, and I cannot make calls.
Restarting the phone seems to fix it, but it often recurs - usually at least once a day.
I have taken the SIM out, made sure it’s clean and unblemished, and re-fitted it carefully. The problem recurs.
I have put the SIM in another phone, and it works flawlessly in the other phone.
The A40 has the latest version of Android installed.
So it looks like it’s a physical fault with my phone.
Please advise as to what solution is available to me.
