Won't detect my sim card

I'm currently running slimkat rom, and my Fire Phone won't detect my sim card. My sim card has been cut down from a micro sim, so I suspect that may be the problem. The same sim card works perfectly fine in my Nexus 6 though. I never tried the sim card when the phone was still on Fire OS, so I don't know if I needed to pop it in first before switching to AOSP or what. Anyone ever had any similar issues?

I have the same problem. My phone is currently on latest build of CM-11

The problem was with sim card slot.
FirePhone has the worst sim card slot in any phone I have ever had...

Had the same problem when sim card got cut. Replaced sim card with a propper nano sim and it works!

Yes, it sounds stupid but I had the same problem. SIM card inserted not exactly right. I kept getting SIM card errors until I finally got the SIM card in right.

Phone doesn't recognize SIM card after restart

Hi. I've got weird problem. Coincidentally, I updated my OP3 to OxygenOS 5.0.1 and at the same day i changed my mobile operator (so my sim card too, of course). Since that day i have got very weird problem. After reboot my phone doesn't recognize my sim card anymore (just like any sim card wouldn't be inside phone). This is happening once in a few reboots. One of the problem solutions is another reboot (But this doesn't always fix my issue). Another solution is to put out sim card nad put it inside phone again. I don't know is it problem of:
1) Phone hardware
2) Update
3) Faulty new sim card
Is anyone having similiar problem after update ?

Samsung A3 2017 Firmware update

Hi Team,
I would like to replace the firmware of my SM-A320F/DS with the European SM-A320FL. As it is Dual Sim phone and I am using the second sim slot for external memory card - 250GB.
Is it going to work? I do not need the second sim option but I need the external card slot.
Many thanks,

Usually is not a good idea to flash firmware for a different model. But let's other say if it will work or not.

Sim card not working

I havent really used my ZUK Z2 Plus for some time, it is my secondary phone.
I recently changed the fingerprint sensor of my ZUK Z2 Plus, that seemed to have worked. At least I can unlock the phone. However, the phone does not detect the sim card anymore. It recognises that there is a Vodafone card in the slot, but I do not get a signal. The sim card works in another phone, another sim card does not work in the ZUK. I tried both slots.
I flashed Zui.4.0.186.Z2_plus.qpst but still i do not get a signal. Any ideas?

Edit: Not sure if the timing of changing the FP coincides with the sim card issue
