[Q] Sim tray problem. Phone does not recognize any sims - Nexus 4 Q&A, Help & Troubleshooting

I installed a micro sim card into nexus 4, it rebooted, after that it does not recognize any of the sim card inserted. Simply i can eject sim card tray, put different sim cards but nothing happens, phone even does not recognize if sim card is inserted or not, factory reset does not help. Sim is OK, i used it on this phone before and i use it now on a different phone. How can i solve this problem ?

Is it cut down?

You cannot put sim tray other way in nexus 4 , it does not slide in . No, sim is not cut, ive got it from carrier and used it before on this phone for about 3 weeks without problems. This is not a sim issue, i have another micro sim from other carrier that i've tried, but it's the same problem.. and both micro sims work on my xperia z, and nokia but nor of them from today are not recognizable in my nexus,,, iv'e looked at the pins in the sim tray, all of them ar not broken, done several factory resets, tried different roms, but nothing helps..

I just bought my N4 yesterday. I had the same issue. It would not recognize any SIM cards. I ended up having to swap it for another one. My SIM is from a different carrier, and has been cut down to micro size. No issues after swaping phones.

[Q] Invalid SIM Card

My device is i9505 and it should be carrier unlocked, I bought it outside any carrier.
I have this device since mid 2013, with the same carrier and same SIM Card.
I only had 3G, and my SIM Card only supported 4G
Recently I noticed that they don't work anymore with just 3G, everyone with compatible device and SIM Card could use 4G
So I went to my carrier, and bought 4G SIM Card, it's from the same carrier I used for the last 3 years
But when I tried using it, my device said "Invalid SIM Card"...
I asked them to try the SIM Card on one of their devices, and the SIM Card worked, but on my i9505 it says "Invalid SIM Card"
I tested with my old SIM Card, and the device found no problem, but when you get a new SIM Card the old is blocked, the device recognized the old SIM Card but I can't make calls, receive calls, etc, etc...
As using my old SIM it still recognizes, I think it probably isn't a hardware problem...
Does anyone knows what could be causing this, and is it possible to fix?
I'm currently using Imperium LL v13 (Custom ROM)
I tried flashing a newer modem from my carrier based on this firmware:

I downloaded the modem from this post:
http://forum.xda-developers.com/showthread.php?p=61852508#post61852508
But it still says "Invalid SIM Card"
I also tested SIM Cards from some friends that use other carriers, these SIMs worked on my phone, and my SIM worked on all my friends phones, but when I try my SIM on my phone, it doesn't work...
On the screenshot below you can see my baseband version after flashing the newer modem:

I had the same exact problem with my I9505 with my operator digitel ( venezuela) , the only solution i had was to ask them for another type of sim card
So it turns out that Lossadax was probably right, the store that I went probably had a type of sim card that wasn't compatible or they had defective sim cards there
I had to buy another sim card from another store, the connector had different size and layout, and now it's working!

Sometimes no sim card error

This phone works well with sim card but sometimes get no sim card error.
Why? I will try reinstall the sim card.
maybe reinstall rom?

Enable LTE on SM-P610 Possible?

I noticed that on the Non-LTE version, on the backside of the microsd card tray, there is a black sticker where the sim card would go. Is it possible to flash the LTE version onto this tablet and put in a sim card for LTE functionality? How can one confirm if it has the LTE modem in it?
Any insight is appreciated
Seems like it's not that easy:
