SIM Card Reader won't read sim card - LG Optimus G Pro

Hello, my phone is no longer reading that I have a sim card inserted. Does anyone know of a fix for this?

Have you cleaned the contacts on the sim or checked if the pins of the reader are not broken?

What would the pins look like broken? and the sim card works in my other phones.

Fixed it. The SIM card tray( the metal top) was not pushing the sim card down far enough.

I had the same problem, i had to place a small piece of cardboard paper folded in two to keep the sim down.
How did u fix yours?

Basically I bent the metal down. I'll need to try your trick tho on my galaxy nexus.

It was weird with mine. I was JUST using it to make a phone call and get on Facebook and I did a reboot and then BLAM...No SIM card?? SO I found this thread and what I did was use an old nano SIM card from another phone that was deactivated. Put my SIM in the reader and then placed the old NANO (you could use another Micro SIM too I guess) right on top of that reader and snapped the cover back on. PERFECT...It needs just enough to press the SIM down onto the gold pieces to read the SIM...NO problems so far...

Galaxy nexus micro sim slot?

Can someone tell me for certain (someone who has the phone or has opened one up), tell me if the Galaxy Nexus has a micro sim slot or not? I can't seem to find a straight answer anywhere...
No, normal SIM.
Just look at the instructional videos straight from google. It does not have a micro SIM. It has a standard (what we think of as standard is actually "Mini") SIM.
Remember though, you can put a micro SIM in a mini SIM slot. You just need a small plastic adapter to make it seat properly.

The Galaxy Nexus definitely takes a normal sim card. The confusion may have arisen over phones4u sending out micro sim cards with new orders but this was a mistake and a standard sim card is the only one that will work in there.

Well like I said above, a micro SIM will work if you use an adapter. The adapters allow you to slot a micro SIM into them and provide extra plastic around them to be the size of a mini SIM.
The slot in the phone is most definitely a standard SIM slot though.

Not entirely true, it is possible to balance/wedge the microsim on the contacts and have a working phone

Yes I agree that wedging random things in sim slot is bad idea, however....
If you happened to be like me and have tons of random mobile crap or sim leftover items like the cards that are credit card sized which house the original micro-sim often, then some of them have an actual cutout of a larger sim original size sim to be more clear which is popped out then the micro-sim is popped out of that piece. It's a backup/cheap way I figured for companies at one time to make sims and ship them out in one pack/card then when the user gets their phone and they match up what sim size they need they have both options....or I could be very wrong who knows.
Any ways, my point is simply that one of those leftover housings of a original size sim that you might have popped out a micro-sim from for another phone can come in handy as all you do is simply place your current micro-sim in the gap where another one used to be and it kind of even snaps into place then you have a bootleg like adapter for micro to original size sim. I don't know it worked me on my i9250 gsm world nexus and verizon.
normal aim
use adaptor

[Q] SIM Card used in Galaxy NOTE II

Hi,
I visited a Samsung showroom here in India today, and I was said by store manager that the usual SIM Card used in Note I cannot be used with the Note II and you may need to cut the sim card (as it is to be done on iPhone 5). Is this true? If there is such a need to be undergone for using the SIM CARD in galaxy Note II?
I've just found out that is true!!
My SIM from my HTC Desire needs to be cut down with a micro sim cutter (Ebay) or a replacement micro sim card from your provider

its better get a new micro sim from your service provider. one of the mobile store guy had cut my sim wrongly, the edges gone, and it didn't work anymore, i did went to the service provider and replaced a sim, also get a micro sim adapter, which will be usefull when you need to use the sim in non micro sim phones.

Yes, it's the same, it'd you are going to convert your standard SIM to a Micro SIM, I would suggest using the dedicated tool for doing it, as opposed to using a pair of scissors or a utility knife.
You can use the aforementioned tools, but it's changed with higher risks of damaging the SIM.

No, the iPhone 5 uses nano-sim, not micro sim like the iphone 4/4s, note 2 etc use.
You can see in this image that the micro sim used in the note 2 (right) is larger than the new nano sim used in the iphone 5 (middle)
Cmon its not that big of a deal..any shop keeper would cut ur sim for free or 100 bucks max..and u can even buy ur own sim cutter from eBay costs 150 rs..
Takes 5 seconds to cut it..

The reason for my hesitation is that, once the cut is made, it makes the sim card not to be used in other regular sim card cell phones.

Well in ebay if you search for sim cutters they will also provide adaptors for micro sim as well. You can use them with your normal cell phones. No problem for you.

Avoid cutting it. Just go to your provider and they will replace the Sim in 15 minutes.

Sim card slot pins broke.. any hope?

Well, just as soon as I bought an unlock code and attempted to pop in a different network's sim card, the slot tried to chew up the sim card.
Once I was able to pull it out, the pins (or other metal objects) came out with the sim card, in pieces. Now, no sim cards are recognized.
Any hope for this? Or has my Xperia Play been delegated to a gaming device, without cell phone capabilities..
You can attempt soldering the pins back in and pray it works..

I see they sell new sim slots, but I don't know how to solder at all. I've replaced the screen and digitizer myself on this phone already (so I'm not completely afraid of working on it), but soldering is beyond my skillset.

[Q] GNex doesn't recognize any micro-SIM card (even with adapter)

Yesterday I had to switch the SIM-card in my GNex. The new one is a combi-SIM-card (an ordinary one where you can break out a micro SIM).
The ordinary one wasn't recognized so I broke out the micro SIM and tried it in my iPhone. It works flawlessly.
Then I used a micro-sim adapter to put it in my GNex again. Not working again. Then I tried to place the micro SIM manually in my GNex. Moved it a little bit — airplane mode on — airplane mode off. Again nothing. I also tried it with another micro SIM card. Again no luck.
The only type of SIM cards which seem to work are the old ones with the bigger connectors but sadly I can't get one of these anymore for my contact since they are all combi-SIM cards now.
So does anyone have an idea how to get that SIM card running in my GNex? It's too young to retire it :/
This is the equipment:
Strange my micro sim works great without adapter. Just needed to fiddle then restarts it and it picked it up

One of the SIM card reader PINs seems to be gone. I already ordered a replacement SIM card reader from eBay for 5€.
The repair-shop told me that T-mobile SIM cards could still work since only the lower right PIN is missing. I don't know why but the shop-guy was right.
EDIT: I was able to fix the missing PIN temporarily by using tinfoil )

[Q] Sim Card not found

I have been using the Korean LG G3 for a while with my AT&T sim card and I did not have any problems up till now. I have pulled the sim card out and put it back it multiple times now and it will still not be recognized. Does anybody have any ideas on what I should do? Thanks in advance!

Try getting a new sim card, and go from there. The issue could be that your sim card is old, or your phone does like it anymore for whatever reason. Alternatively you could try the same sim in another phone if that's an option.

Thanks for the quick reply. I have actually already switched the sim card and it is working on my other phone. So I am pretty sure something is wrong with my phone not the sim card. I have also reset my phone one time. Still nothing. Any Ideas?

You could back it up and do a hard reset this isn't ideal, but it usually fixes things.

Check the slow where you put your sim card into and see if any don't look like they are contacting the card. I wouldn't mess with them, because they are fragile just look.

I looked at the pins and I'm guessing those are the ones in the top of the slot. It seems like two pins to the very right are not touching the card.

I have the same problem in my skandinavian (international (unlocked)) i think it has something to do with the boot speed(fast boot) because i got it to work when i backed my phone up and it rebooted but it always happens again when you just pull your battery out when the device is still on i factory reseted and it fixed it self permanently
I'm having a similar issue as well with the Verizon version. It won't read a micro sim (the one that was activated in it) but it will read a nano sim that I have placed in an adapter to make it fit. Both sims are Verizon, active, and have different numbers. I have no idea what the issue could be.
EDIT:
It seems as if a pin or two weren't making contact with the sim card. After putting a little piece of 3M tape on the sim card, it created enough contact and all is well.

I have the exact same problem if i put a micro sim card it wont read but if i put a nano sim with a sim tray it will work...any solution..
I know this is an old thread, but I wanted to post an update just in case someone else was having this problem. I ran into it with my VS985 a few weeks back. First it was just not reading my sim, but then got worse and wouldn't read any sim I put into it. I was able to correct it by slightly adjusting the pins on the sim reader. I took needle nose pliers/ a knife and gently bent them up a bit. After doing so the phone immediately read my sim card.
I hope this helps someone else if they encounter the same issue.
I have a similar problem. My G3 only accepts and sees one sim card, the one from my old provider. With all other sim cards there is the message "no sim card detected". I tried different working sim cards, no of them are being detected. I switched my provider a few weeks ago and since the problem exists. Before everything was fine.
I also tried adjusting the pins a little bit but so far nothing helped..
OK, I have the same issue: my G3 shows "no sim card" message. The solution is to replace the sim card/microsd slot. However, my phone is not covered by warranty anymore and the incredible honest guys here in Brasilia (Brazil) want to replace the whole main board and charge me for it. So, I'll have to replace that slot by myself. I bought two slots on eBay (search for "lg g3 sim card slot"). Micro soldering is not an easy thing, but there are some videos online that can help. And, if necessary, you can always look for a repair shop to do it for you, providing the piece (the slot). Until the slot replacement, you can try this, it's working for me: I noticed that if you ever accomplish to start the phone normally, you should never power it off to keep it going on! It seems that the sim card is "checked" only at boot time. (I managed to keep my phone connected to the operator for days, but after a stupid friend of mine restarted it, the error came again). To help getting a successful boot, with no sim card errors, I suggest to firmly press the sim card/microsd against the phone while it is starting, from the moment you release power button until the lock screen is shown. This proved to be very reliable, at least for now.

Thanks! This worked for my Sprint LG G3. Kind of a pain to boot while holding the SIM card down but it'll do until I upgrade my phone.
Also, I noticed you don't have to reboot the phone - it will also check for the SIM card when updating PRL. So you can go to Settings->System Updates->Update PRL while holding down the SIM card. Once the PRL update completes it should recognize the card.

Yes, it's hard to hold the simcard through the boot time. Here it takes 30s...
Unfortunately, GSM versions don't have PRL option. And I haven't found another way but rebooting.
Reboot your phone multiple times until it detect the sim card. Once done go to security then set up sim card lock and and enable sim code identification. Now wen you reboot your phone it will ask to enter the pin code to unlock your phone and it will detect your sim card.
The issue is because it rebbot too fast i guess.
For the boot loop issue change your battery.
Thanks all, i set little schotch tape on my card now it can recognize it!
SORRY FOR MY BAD ENGLISH!
The pressing down during startup method worked for me! Took a few tries though, and it only worked when I removed the micro SD and pressed directly on the SIM.
