Invalid or missing sim card

Just received an HTC p3300 with O2 contract. Within one day the network disappeared and I got the "Invlaid or missing sim card" message. It's all brand new. Obviously I can return it if neccessary but is there anything I can do about this?
If I plug the USB cable back in, sometimes the sim card starts working again.
I have read that this problem has occured on other HTC models in the forums.
I have tried putting another sim in which worked for a little and then stopped.
Any clues?

I had a similar thing with my Orbit from O2...
...it turned out that I had not secured the Sim Card correctly by clicking the little cage home!!
I have been using Co Pilot and my speed camera warnings stopped working so ended up deleting and putting on TomTom

Hmmm
I have made sure, several times that it is secure with no avail. But it is true that there are times I can give the sim a polish and reinsert it and the sim will be detected again. But if this is a matter of bad contacts or a warped sim cage or something am I better off sending this back or is this inherent in the design?
Thoughts?

Solved but not satisfactorily
Ok, solved the problem by putting a little bit of toilet paper between the battery and the sim card, wich exerts pressure on the sim against the contacts. At first this led to the corrupted file names on the SD card malarky. But checking the contacts and reinserting the SD card solved this problem.
But this is hardly good for a brand new unit. Should I send it back?
It doesn't bode well.

No SIM card error message

Have any Glide owners seen this? My wife's Glide was replaced at an AT&T warranty center recently (home,back,menu, and search buttons stopped working) and every once in a while I see the no network icon on the phone. I go to Mobile Networks and the no SIM card message popup appears. After several power off, take out/put back in SIM card, power up phone attempts the phone eventually sees the SIM card and all is well. I do notice that the SIM card does slide in/out very easily. I put in a small piece of paper to keep the SIM card snug, hopefully that will fix the problem. Anyone else experience this problem?

I had an issue with this before try to tape the sim card in place see if that helps
Sent from my SGH-I927 using xda premium

Tried the tape and still got the sim card error message after a day or so. I went to the AT&T warranty center and they put in a new SIM card. The phone works fine now and hopefully will stay that way. The tech put a note in our acct of the SIM card issue in case it pops up again.
Also, FYI.... Samsung Kies does NOT work when you have the SIM card error message (for backup/restore). Kies just spins the "Connecting..." status forever. I spent a few hours selecting the troubleshoot button that reinstalls the drivers, uninstall/reinstall Kies, installed Kies on another laptop, etc...nothing. The moment the SIM card issue was resolved, Kies connected just fine. The Glide also seems to like to enable USB debugging mode on its own, which disables the MTP connection that is required by Kies. fun.
It would be nice if Kies threw a "Cannot connect, no SIM card detected" message...

I have the same issue. My glide came refurbished and about once every two or three days I will notice that the phone is no longer recognizing the sim card. I have to take the battery out and take the sim card out. Then i have to put the sim card back in and then the battery and turn it on and its fine for another few days. I have had 3 different sim cards and it still does the same thing. AT&T just refuses to acknowledge that its not the sim card.

I have the same problem where ICS will just not read a sim card. I have tried multiple carriers SiM's and none of them work. Does anyone know how we can force Android to read and then request a SIM. It is not a problem of the SIM not being seated properly since it was working directly before the ICS upgrade and when I downgraded the first time it read my SIM without a problem.

I have not yet had any problem like that, I have had issues with data and wifi, but later found that it was the software I used before for battery management had an update that shut off those services and have fixed.
SIM card errors though, I only got 1 once but that is because the simcard holder in my phone seems loose and it wiggled out once and after that was nothing a gentle squeeze couldn't fix.
Samsung SGH-i927:
ICS Leak I927UCKL1 4.0.4 Stock
CWMR Touch v4.0.0.1
Keyboard fix
Superuser 3.2r3 ARM Optimized
LiteKernel v5.2

quick update, so far so good with the new SIM card. no sim card errors

spoke too soon! got the sim card error this evening. went to the AT&T warranty center again and got a replacement phone. this one better work.

SIM card error mesage again with phone #2. so far:
1) new phone, same SIM card, same battery
2) same phone, new SIM card, same battery
3) new phone, same SIM card, same battery
I'm starting to think this might be a cell tower issue since the other problem with this phone is that the phone would sometimes not ring or show any missed calls. maybe now it throws the SIM card error instead??
the mrs is going to go to the warranty center again to try to get a new battery and charger. we'll see.

final summary, new battery and still get the sim card error. AT&T is sending a Galaxy S2 skyrocket as a warranty replacement. My wife tried out swiftkey 3 and is willing to make the jump to a touchscreen keyboard.

Sorry to bump an old thread, BUT, a factory reset fixes the issue. My wife had this problem. It occurs if the SIM card is ejected by accident for any reason while the phone is on. The simcard does not lock in at all so I can only assume she bumped it just right. I got a full replacement phone from ATT, and while messing with it while on, the simcard fell out. After turning it off and putting the sim back in, the same problem occurred on a brand new replacement. A factory reset solved the issue.
I was googling about this and saw this thread. Figured I'd add my 2 cents, and what solved it, but I am still replacing the sim just in case.

[Q] SIM failure

Hello i've started to have problems with SIM card, sometimes randomly it just pops up window that SIM card is not inserted and all i can do is restart phone and even when i restart it it cannot find the SIM card, i have to pull out the battery and reinsert the SIM to make it work, it might be because of the guy at t mobile who cut the SIM card wrong and it gets dislocated in the solo and also it might be system failure so im asking is anybody else experiencing this?

Yes I experienced this. It was really annoying. I managed to fix it by removing the sim card and wiping it gently using cloth. If that didn't fix it, then ask your carrier for a new sim card, because yours might have become defective.

SIM not detected
Hello, i have the same issue.
Nothing helps. Put in and out different SIM Card's. No one of all SIM are detected.
Could it be, that a self cuted SIM, to Microsim Formfaktor, damaged the SIM Reader of my new Note?
But yesterday it works really fine with the self cuted SIM. In the Evening i put out the cuted SIM und put in a other (Origin) Microsim from an other Carrier, that works fine too.
After that, i put the cuted SIM with an Adapter into my old Desire. Then i have issues with 3G Networks. The Desire find 3G Network, connect to the Network and lost the connection immediately. When i choose only 2G Networks it would connected.
Today at the morning, i want to know what's wrong. Desire or cuted SIM. I put the cuted SIM back into my Note. Boot the Note. If it booting up, it poped up a message, that the Phone must be restart because the SIM has been changed. When the Note reboot again it, it shows a SIM Icon in the Notification Bar and tells it's no SIM Card inside. I tried the other Microsim (OEM cuted) it won't be detected too.:crying:
Does anybody have a solution for me?

Thank you i tried to clean the SIM card a little bith with cloth and spits and grits, did not happen since then, i hope it will be solved, if not i will try to get a new sim card from carrier, after all the SIM card is like +11 years old

[Q] Huawei P6-u06 sim card slot issue

I have inserted sim card tray in the wrong way, and it has stuck (without a sim). I can't remove it. Guarantee guy told me that it's immpossible to remove it without crashing phone main board, but I cant believe it... I think it should be removed somehow without damaging phone, because it looks so simple issue, but without fixing it, i can't use my new phone...
How i should remove this tray form the slot?

Your not alone. There are others who messed up when inserting sim card slot, but unlike you, others inserted simcard somewhat rough i think and screwed up the board.. So Huawei ended up putting a video tutorial: http://consumer.huawei.com/en/mobile-phones/support/downloads/p6-u06-en.htm#anchor

That's a video about how to insert your sim card into the phone, not how to solve a problem like inserting the sim card case the wrong way, so that video doesn't really help solving something, it's just a tutorial on how to insert not on how to eject a sim card case inserted wrong.

Well,open the phone and solve the problem...or take it to someone who repairs phones...

[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.

Just hard reset it and it is still not working. I think it might be a hardware problem.

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.
