"invalid card " error

Hello,
I'm getting " invalid card" error randomly ,in my HTC one 32gb unlocked version,I bought it from HTC online shopin May last year ,was working fine except the issue of purple tint in camera for which I sent it to repair to Houston ,Texas a month back ,they did great job ,my camera working great ,no damage to device .
But now I'm having issue of invalid card ,which occurs randomly,rt now I'm s-off , running viperone Rom. I had this problem with stock 4.4 Rom & custom rom as well,I tried to change firmware & also roms but with no effect .
Many a times phone works flawlessly,but sometimes starts showing this error causing call drop .very annoying.
Some says it is because of defective SIM tray,it that case why I had no issue earlier?why it occurs randomly ? Why not always ? Enquired with service provider they say no issue with them
Any one having this problem ? Any solutions ?
Plz help

hmm i also think so.
but why it will work initially and than stops suddenly??im not able to understand
Or is it a software issue ? Many people complaining that kitkat update causing this type of errors !
When they took apart the phone and put it back together they may have broken or left loose something that eventually shifted or shorted out. Or it may just be a fluke that the sim slot went out. But i would try to blame it on them lol :-\

There may be an internal short that fries the sim card.

[Q] Sim card problem with CM11

So, I installed the latest CM11 from Maclaw, build 20140408, after finished booting, a pop up shows "You need to refer to the SIM card instructions that came with your phone". My sim card is fine when i tried it with my other phone and my IMEI and baseband are intact.
I tried reflashing and resetting the data but the problem is still there. I even tried the latest carbon rom and the same problem occurred. Then I ODINed my phone back to stock rom and the problem is gone.
Is it just me who's having this problem? Is there any solution to this?

Change sim card or remove it and put it back maybe this will solve your problem
did you do a factory reset before flashing and cleared dalvik? if not, try that...
also here is a good flashing guide

XT1068 suddenly stopped detecting SIM Card (both slots)

My XT1608 stopped detecting SIM cards all of a sudden. The same SIM cards (cropped and official) are working with other devices. It was running the latest build of Lineage OS but reverting back to stock Marshmallow doesn't solve anything.

Mi3 No SIM card issue

Hello, I was using lineage Os latest nightly when I encountered this issue. I wanted d2w. So I flashed Zurion X. Phone rebooted to TWRP. So I flashed recankut kernel. Phone worked. But I noticed that it started showing no sim card. I tried flashing Lineage Os back and nothing. So I flashed MIUI latest global beta via fast boot. No SIM card issue persists.. Now Im beginning to think that the issue is hardware issue.. I dissembled the phone.. But the sim card connectors seems to be OK for naked eye.. MY phones I will is not affected, neither the baseband.. So I'm out of options now. Can someone suggest me a workaround to bring my phone back to life.
Thanks.
Also it seems that I can make emergency calls.. Which means the radio I working

It was my sim card tray.. The lower right coner of the sim tray was broken and it interfered with the sim card identification mechanism. With a new simple card tray my phone is fixed.
If the SIM card tray is damaged (for example, a piece of plastic is chipped off or a metal plate is deformed), this can be the cause of the problem when the Xiaomi smartphone does not see the SIM card.
I had such a situation on my Mi 3. In the service center they could not find the cause of the problem, I found it myself.
I hope this information will help to somebody.
