Phone doesn't read my SIM

I have been using CM11 (14-03-2014 I believe), without major problems until yesterday. Sometimes my phone seemed to disconnect from my SIM and I had to re-enter my pin code to reconnect to my operators network. But as of yesterday my device doesn't seem to recognize the SIM card, It doesn't ask for a code at all and can't make any connection whatsoever. I didn't change a thing, this problem started out of the blue.
I wiped cache and dalvik, updated to the latest CM nightly (08-05) but that didn't make any difference. In other threads I read about the baseband that might need an update, but I can't check which version I have now because when I try to enter the hidden menu I get the no network connection error. The strange thing is that CM11 has worked with (I guess) the stock baseband.
Is my phone tripping or could it be that my SIM card is broken?
Help and thoughts will be very much appreciated

Try it on stock to be sure about it.

After some searching I found a phone that could fit a regular SIM card, a Blackberry 9900. My SIM worked perfect in this phone, so that is not the problem.
I Also did a complete wipe and installed a stable version of CM 10.1.3, but that didn't seem to help. I hoped that a downgrade would have done the trick. I might try a ICS ROM or the stock firmware, but I kind of lost hope and i'm starting to think this problem is hardware related in stead of software. I'll report back with results on stock firmware and the ICS ROM.
How can I make sure the SIM reader in my phone is working properly?

Sorry for double posting, but I got an update:
SIM wasn't working with ICS so I decided to go back to the stock ROM. However, when I tried to flash V20B.kdz with KDZ_FW_UPD, the program got stuck at wParam=2010 and iParam=210. The phone is now stuck in S/W Update mode, and I haven't found a way to restore it yet. I will argue a little more with my phone when I get back from work, I'll open a new thread on how to unbrick when I can't do it myself.

If it is under warranty. Flash the stock COS and lock the bootloader. Send it to service centre. I had the same issue after using it for just one month. I had tried all possibly Way's. But didn't work. I sent it for service and got it back after 15 days. They changed the mother board. Now it is fine. I am from Hyderabad, India.

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.

Help!!! No service problem in my Le2 X 526!!

Hi friends,
I have le2 x526 model and i was on stock eui 5.8.19s.
Network was getting weak and weaker from last few weeks, i thought its network provider issue so neglected it..
But now i have no service in my phone and tried to do manual search but always shows 'error in finding network'.
I flashed stock 5.9.21s rom but it didnt helped.. Hard reset didnt work..
Still facing the same issue..
Everything else are working flawlessly but no network.
I checked for RM cable inside the phone but nothing is damaged so i think i its software issue..
Any help will be appreciated..
PS- anyone who can give correct modem files for le2 x526?
