Nexus 4 not recognizing sim card - Nexus 4 Q&A, Help & Troubleshooting

I printed out a template and cut my old sim card from Rogers. It's activated and the back of it says HSDPA.
I have tried inserting the sim while my phone was off. I turned it on and it still said no sim card. Do I need a new sim card?
One side of the gold chip touches the metal tray. Does that make a difference?

I chopped my tmobile sim card (from G1 days) and the gold chip was larger than the replacement sim that I got (G2X). I popped the newer sim into my G2X and activated. Then removed and used the template to chop and it detected immediately one placed in the tray.
Sounds like you need a newer card to me.
Hope this helps.

Yes you need to get a new sim card,
The problem with Nexus 4 sim tray is that it's metal and not insulated like iPhone 4,
This also was the cause for data drop on my side, I had my sim card replaced after my first one just completely not working anymore. And just so it won't happen again, I took a thin piece of paper to cover part of the sim card just so it doesn't touch the metal tray on both sides

My card was cut and seemed top work fine until it sit if popped outs place one day, took it it and grinded away the edgy bits that the cutter left behind so it was smooth and got nicely into the tray. Benn working ever since (fingers crossed!)

SIM Hotswap

Hy,
I hotswaped my SIM card few times.
Went to Comm Manager, Phone OFF, take SIM out, put another one in, Phone ON...
I'm just curious if something could go wrong by swaping SIM this way, since it is a lot faster not waiting the device to reboot.
Cheers!
Hi
I am curious how you swap the sim without taking the battery out.

Andrew
Bend it over the battery with a toothpick/stylus or fingernail, then just slide it out. Its actually easy, and it saves time.
Yep its possible !
I would be wary of bending the metal sim retaining bracket though.
On my Kaiser I had to pack it out with a piece of paper to ensure the sim made good contact - and on that phone I hot swapped with no problems.

Andrew
I have been swapping sim cards quite a few times, I always use paper, the size of a sim card and leave it in inside the cover.
Very easy and the paper protects the battery and sim card from being scratched.

[Q]Remove SIM reader

So...recently I switched to a new T-mobile prepaid plan, and the sim card the pack came with was (unbeknownst to me at the time) a microSIM.
(Wasn't paying attention to the package. Phone had been turned off for days, I was excited). Being the stupid person I am, I put the microSIM card in my sim card slot and (*gasp*) it was too small. I couldn't get it out with my fingers, so i took a paper clip to it. I suppose in the process of removing the sim card, I must have pushed some of the pins down. The phone no longer recognizes any sim cards. I've taken the phone apart down to the motherboard, but the sim card reader the the sd reader are attached to the motherboard. Does anyone know of anyway that I can remove them from the motherboard so I can access the pins underneath the reader? Thanks in advance.
Sorry for the long post...I like typing..

They aren't actually attached to the motherboard, they are attached to a thin metal plate above the motherboard, and connect underneath with a small black ribbon on the right hand side (not the camera ribbon). You can gently undo the black ribbon cable that wraps underneath on the right hand side (near the black coax cable), then unlatch the tiny metal tabs all around the metal plate they are attached to (I used a small flathead to pry them), and pop the plate off. Can't remember if you can access the pins from there, but you might get a better look at it at least. If I remember there are a few little holes under the sim reader, where you might be able to access whatever you jammed up.
Good luck!

Single SIM -> dual SIM

So I have seen folk saying you can put dual SIM firmware in a single SIM model and it works.
Where does the second SIM fit/what physical modifications need to be done?

There is a dummy plate covering the second sim slot, right above the first slot.

So the plate is removed, and all that's required is an extra SIM card holder?

Extra sim card. You don't need a holder, same like the first sim slot. You'll just plop it into the tray.
To further discuss what dictionary was saying: all Moto X Play SIM card trays hold 2 SIMS - The difference between the two is that the single SIM models leave the factory with a plastic insert put in place with a gooey adhesive where the second SIM fits. The contacts are all ready there for it when the tray is inserted to the body. By carefully removing the insert & adhesive you are set for putting a second SIM into the Play.
HOWEVER you still need to flash the appropriate firmware to complete the transformation. There are more than one thread discussing the software side of things. FWIW.

So.... Anyone else having issue's with their SIM cards?

I bought this phone sometime in May 2015, and started having SIM card issues about 6 months ago. What normally happens is the phone will tell me it can't detect a SIM card, and I'd have to realign it. After upgrading to Marsh Mellow (NOT Beta), my device would tell me at least 3 times a day that it "can't detect a SIM Card". Well, today it REALLY can't detect a SIM card. Restarting, changing to airplane mode, clearing cache, even re-aligning the SIM does nothing. Heck, even putting it in the 2G slot does nothing!
So has anyone else experienced this issue? What did you do to solve it?
Could be a couple of things. Either your card is loose in the socket. In which case you can try shiming it with paper. Or the card is bad. Then you'd need to talk to your provider for a new one.

Had this problem 2nd day I bought phone, sim slots broke, the spring put the sims out and I have to force them in.
Now to put out the sim I use a needle to drag them out.
anyway don't know if a coincidence but after mm sim2 tells me random insert sim2 message.
I resolved putting some tape on the sim to tight in the slot.
a tip, put tape only on the center of the sim, so a stripe of tape in the center on long side.
in this way we force the sim only to fall in the middle making strict contacts.
Anyone having problems with SIM's not stay in the slots, don't loose your time with paper...
USE PLASTIC, you can cut a wire ribbon to the right length and put it between the SIM cards
I sent mine in for fixing. Its under warranty.

Yep also got this. Uk train tickets are the perfect thickness to slip into the slots and a micro sim sits nicely between both slots to keep both sim cards in place.... Shockingly poor component quality and its happened on both zf2's I've owned. Oddly with MM I'm having less "sim not recognised" messages. In fact none since I upgraded, might me be better quality train tickets tho...

Anyway on ebay the full slots replace is around 4 euro, for who has the ability to dismantle the phone. Search ""ze551ml cable slot"
Have you ever tried actually replacing your SIM card? I've had a SIM card error before and when moving it from my ZF2 to my wifes ZF2 and to my Huawei Mate 2, same error. They do actually go bad from time to time.
It's not cards on the 2 I've owned its the spring catch that holds the cards. Neither work anymore.

I had my phone randomly get the SIM card 1 and the SD card disconnected. Replaced the whole SIM module under warranty ~3 months ago.

Stuck SIM tray

hello guys, yesterday I was trying to switch my sd card and what I didnt expect, I couldnt remove the tray.
I thought maybe sim or sd was stuck, so after a while, I was able to gently remove it with a knife.
As it turned out, that wasnt a problem and I still cant remove it fully...
ye...why does this have to happen... anyone have some trick maybe? Or experienced the same problem?
Thanks
It's possible that your SIM card (or a storage card) has become disloged, ie; is not laying flat in the tray. I think the best you can do is to gently push the tray back in and lay it flat face up and see if you can shake it a bit to get it to settle into the tray. If that does not work, I would take it somewhere for repairs.
Just cant believe this really...
I managed to break it, so the stuck piece is still in my phone, but now I am at least able to put a sim and sd card into it.
Contacts little bent, but its how it is and the phone works. Will have to ask about warranty service on this, I am really curious, what will they say...
So be aware, even thing like this can happen...
Yes, this SIM tray is very fragile. You are not the first.
Exact same thing happened to me. I believe there is some clip or contact that detects when the Sim tray is inserted or ejected and it gets caught there. They used a flimsy plastic Sim tray and it breaks in the same place.
The SD card and Sim tray still work. Just have to reset the phone when you change it for the phone to detect the changes.
Happened to me exactly like yours...i used a very this bit of plastic, with a bit of blue tack very firmly attached to the plastic and gently, VERY gently pushed it in to the sim/sd card slot and only took 2 attempts but the bit that broke off came out!!
Then went on Ebay and got a brand new sim/sd card tray and voila!
Cost me £4.50 for new sim tray, but working perfect now.

Any ideas on extracting w/o breaking the tray?
I have the exact same issue as the OP (before his tray broke).
Does anyone know any tricks to extract a stuck tray without breaking it?
edit: nm. Broke the tray. Took no force at all.
So the issue here is one of the SIM reader pins is sticking up and is catching the tray. Trying carefully to bend it back where it belongs.
edit #2: Can't bend the pin back w/o disassembling the phone. Going to borrow a heat gun.

Hey there Matt, I got exact same problem, tray got stuck and I rushly pull left over broken tray. I replace the sim tray but now sdcard not working. It is detected and attempt to format the card but fail at 20%. I'm still try to repeatly removing sim tray before I take it to LG.

So you meant when replace that sim tray, you need to hard reset so it will detect the sdcard? Because I have sim tray replaced, sim worked but sdcard wasnt, it keep fail to format at 20%.
You must have damaged some pins. For me all my.pins are intact and the broken piece is still in the phone. I have to do a hard reset for mine if I want to change the Sim or SD card

Same here. Damaged SIM reader pin. Tore the phone down and it's not clear if it's repairable or not.
Regardless, I'm writing off my G6 (just 1 month after I got it). I'll pickup a V20 for now, so I don't have to look at another SIM tray.

I went to LG and they ask for mainboard replacement cost $400, what a joke! Looks like they wouldnt replace only damaged part.
Even if you replaced it. It won't be long before it breaks again in the same spot... If it was a metal Sim tray it would be a lot better. I'm going to avoid LG phones from now on.

Bad design
I have had 3 LG G6s, each one has had this happen. It sticks in the corner by the sd card contacts. After it catches it will not read SIM until i get a new tray. I think there may be some sort of pressure switch. I wish LG would replace it with a G8x...
Even the models w/o dual sim capability have contacts for a second sim. These rub against and can get stuck at the tiny pads on the underside of many mSD cards. This will cause the tray to get stuck in the frame for additional friction. If this happens to me again i will try to pull the tray out with some adhesive tape to be able to apply force in the middle or at the left side, where the sd sits, instead of the opposite side via the hole.
Especially the newer, bigger mSDs seem to have such pads, none of my old ones has one, that's why i didn't test whether you could sadely remove the pad. Probably there's the bare flash die underneath.
I solved the problem...its called the LG V30!
Love it!

Hi, I got the same problem. The tray broke down only for the SD card and SIM slot is intact. But the phone does not anymore recognize SIM card. So do you think that I did not damage the reader and it's only a matter of getting a new SIM holder?
If you ran into the issue with a sticky mSD, the contacts for the second sim msy be bent/broken/shorted. Whereas only a short may prohibit use of the primary sim slot. And the contacts may not even be soldered to the pcb on a single sim phone like p870. Otherwise just the flimsy plastic tray broke. On my Iphone 4s it was made of metal. And the lever to push the thing outwards was centered and not to the right side, which makes even pushing out an empty tray difficult.
I finally got replacement tray and can confirm that SIM reader started working again. So it indeed seems that there is a pressure switch and it did not activate when the SD card compartment was damaged. No I just worry do I dare to remove sim tray ever again.
My current 128GB mSD in the p870 has a sticker on the back like most mSDs at higher (32/64GB and up) capacities, but this time there's no friction with the useless contacts for dual sim.
But anyway, once the tray has been pushed out slightly, you have to try to grab and pull from the opposite side while pushing the pin in, otherwise there's high friction.
