SIM card not inserted - anyone else had this problem?

Hi all,
Just got home, looked at my mobile and it said there was no signal - so I turned it off and back on again, then it said there was no SIM inserted. Keep restarting the phone, keeps saying the same thing. Why?!
Am going to try it in my old SE K850i to see if it's the SIM card or the phone at fault.
In the mean time, does anyone else know of this fault and how to fix..?
I didn't the drop the phone or anything, it was just in my pocket, on it's own - like it always is!
Cheers

Tried it in my K850, works fine. Please someone help

yeah i usually dont put the sim card all the way in but slightly in and it works

I've re-opened this thread due to me misreading....DOH! Apologies (Mental note to one self.......follow own advice and read before posting).

you could try to clean the contacts on the sim card connector of the phone with a q-tip, and see if that solves the problem.
also check if any of those contacts appears to be bent or something, and so doesn't make a connection with the card.

Everytime I open the back up to remove the SD card, I get the SIM card missing bit even though I have not touched it! My HD is only 3 months old and it has done this from the start. I just have to remove it a bit - shove it back in and the phone accepts it is there. Annoying but not enough for me to send it back.

hmm, maybe try to make the sim a bit thicker so it doesnt move around (it shouldn't move by removing the back cover, but it seems to happen on your phone / sim combination.
try putting a thin piece of paper on top of the sim (not the contacts side, but the side facing to the battery cover)
maybe that prevents this problem?

Missing simcard
I have the same problem with my simcard. Though something strange happens when the phone is off for more then 10min, it works fine and notices there is a simcard for like 30 sec after which the error pops-up again. I have tried all of the above things, my simcard works fine in my other phone, adding some paper to thicken it doesn't work either
Anyone who could help me with this?
P.S. sorry for the bad english

As in post 7# written, put some papersheet in the simholder above your simcard to increase the contactpreasure. This surely helps.
Tis trick is also useful for all dualsim users who thik the dualsimadapter does not work in their device (but after using this trick get astonished!)

for Thysiey:
Try to switch to Gsm mode to test . Maybe you have bad umts signal? Happens at other places too, or only at one place?

Got the same issue here...
I cannot move the SIM because it is being hold in place by the battery. (to little room)
Adding a piece did not work either.
Anyone got another solution?

anyone? My mothers HD just got this problem now. She has a new phone and for the contract renewal she had to read the backside of the sim. The phone all of a sudden didn't recognizes the simcard anymore.. I tried a few other simcards but it won't read it anymore.
My plan was to sell the old phone but now it's almost worthless just a shame it is still a great phone to operate.. handy with the navigation and all

Inserting Sim Card

Hi There,
I'm new so apologies if this has been asked before, I did try a search but to no avail.
I received my HD2 yesterday and when trying to put a Sim Card in it is really really stiff, I managed to snap one in the process (thankfully Virgin are sending a new one out). I then tried with an old Vodafone one which I got in but it took a bit of force and even then the phone didn't recognise it, upon removal it seems to have scratched the simcard contacts fairly badly.
Am I being a complete idiot or do you think I have a problem with my HD2?
Many Thanks
Ben

possible problems could be
inserted the wrong orientation!
trying to insert into the SDcard slot!!!!
SIM card usually comes in a bigger card, maybe there is still some excess plastic on the edge of the sim when you removed it!
Possible that there is something jammed in the SIM slot!
Or maybe there is something wrong with your phone.

only thing id say is the cut off corner goes in last.every phone i've seen beforethe cut corner goes first, but im sure it won't be that cos of course we all read the manual cover to cover before putting the sim in....didn't we? hehe

Thanks for the replys. I am fairly renowned for not reading instruction manuals (like all men i guess!!) but for once I actually did.
Defo tried to put it in the right way but it just wouldn't go in, i've tried this morning again with an old disconnected sim card and it seems to have free'd up quite a bit, it still feels kind of grindy (apologies for the made up word) and nothing like inserting a sim card into any phone i've had in the past but i'm keeping my fingers crossed it'll be fine.
Just got to wait for the replacement virgin sim now which is annoying because i'm itching to get using it, it's a beautiful bit of kit.

If you are in any doubt, get the phone switched out for a replacement. If there is a fault with the SIM socket, then it may well reappear when you least want it in the future!
You are trying this with the battery removed aren't you? It can be done with battery in but it is a lot more difficult to get the SIM card properly under the locating lugs.
I've switched SIM cards a lot, and there is absolutely no problem- it is as smooth as you'd expect from a snug-fitting slot!

Hi Neil, thanks for the reply, yes i'm trying it with the battery out and it definately couldn't be described as smooth so I suspect there may well be a problem with it.
I shall give virgin a call and arrange for a replacement.
Thanks again for your help.
p.s This is an awesome forum, i've been studying it all week in anticipation of receiving my HD2 (first winmo phone), looks like i'll have to wait a little longer before I get to properly use it though

I would get it replaced!

would be epic, is he tries to put it in the sd card place

I do have my moments but not even I could do that!!

SIM card issue... any advice?

I'm not sure if this is a common issue or just an issue with my sim card.
Looks like the sim card just stopped working this morning. I can't make/receive any calls or texts and the lock screen says "Please insert SIM card and restart".
I've restarted about 3 times now and have tried removing and reinserting the sim card, with no luck.
I figure I'll need to take it into a T-Mobile shop to get a new sim card, but my Vibrant has been rooted and has a the Obsidian Froyo rom installed.
Should I just plug the SIM into my old blackberry and take it in that way for replacement?
Or is this some known issue that can be easily fixed?

I have had this happen to me twice. Once, the SIM went bad (it happens).
I called TMO told them that it's not working & they said they'd get me a new SIM. I had the option of going to an authorized TMO store or getting it mailed to me. I went to a store, they installed & it off I went.
The other time, I took some rubbing alcohol and a QTip to it & cleaned it up, let it dry, put it back in & it's been working for a little over a week now
So, I'd try giving it a cleaning first and if that doesn't work, give TMO a call.
If they don't know that you have the Vibrant and think you still have a BB, then yeah, I'd put it back in that rather than bringing in the Vibrant if you have to go to the store. It's just easier when the person helping you isn't trying to force you to change your plan at the same time.
Question: The phone won't let you do anything without a SIM card? If that's true, that's just another reason to be glad I SIM unlocked my phone....that would get annoying!

Old Tmobile sim cards actually have a certain amount of times they can connect to the network tower. If you use airplane mode a lot it you may reach this point quickly.
And some sims cards just go bad. Which I think is the case with yours tjhart85. Take the phone and card to Tmobile. Tmobile will change the sim card for free.

Yup, turned out the sim card just went bad. Called up T-Mobile customer service, they put a not on my acount, and went into my local T-Mobile store and got a new sim card. Phones working great now. They didn't even ask for the old one and didn't have to look at my phone.
Thanks guys!

[Q] SIM Card issues with CM7 on HTC Inspire 4G

So for a while now (probably 3-4 months) I've been having SIM card issues and I don't remember if they started before or after my phone was rooted and running CM...Anyway, a little SIM card thing shows up in my status bar and it says like "SIM card not recognized" or "Please insert a SIM Card" or something along those lines. It doesn't let me use the network at all. Usually I fix it by turning the phone off, taking the SIM Card out, putting it back in, and turning the phone back on. Sometimes it'll work, other times, I'll have to repeat it. I thought the problem was the SIM Card because it had 3 scratches on it from the contact points, so I got a new SIM Card yesterday but it's still doing the same thing. When it started I was either on the stock ROM (unrooted), CoreDroid, or CM7 (stable). About a month ago I started using the CM7 nightlies.
Does anyone know what the problem might be? Could it be the phone itself?

Same exact problem here. I don't run nightlys but I really need to try something that I'm not ripping my phone out of the OtterBox in the middle of school.

Nexus 4 - SIM problem

Hello,
I just got a Nexus 4 16GB (had a 8GB before) and I've to reenter my PIN code almost every time I'm unlocking the phone when it has been in deep sleep. (the card is locked and the phone is disconnected from the network)
I first thought it's caused by custom ROMs, but it's even happening on stock ROM/kernel...
Am I the only one with that kind of problem ?

If you get the sim pin wrong a couple of times, the card is locked and you need to call your provider for a personal unlock code.
If you keep trying to unlock it eventually the sim will simply become inoperable and you'll need a new one.

I can unlock it without a problem after entering my correct pin.
So it is not a problem with the SIM or my provider.

Go into Settings > security and then there should be an option along the lines of Sim card lock. Try checking in there.
Sent from my GT-I9100 using xda premium

Disabled the pin lock for now.. But the signal still drops when the phone is longer in deep sleep.

I had the same problem!
I don't know if this is rom or kernel related, but since I switched to ParanoidAndroid it's gone....

Ah finally someone with the same problem.
I've already been running PA, but the problem did still exist.
Did you change anything else beside that?

i removed my SIM again and cleaned it.

i've also had that issue the second day after receiving the phone. I removed the sim, put it back in but that didn't help - i looked at my sim card tray and i realized that a one side of the sim card chip was close to one metal side of the tray and i figured that could be the issue - so what i did is i took a stripe of adhesive tape and made sure they wouldn't touch - I haven't had the issue again and it's been more than 2 weeks.

Uh...I remember a kernel arg from my old HTC Topaz WiMo-Device, which was able to run XDAndroid.
The argument was pm.sleep_mode, and it is still available on the Nexus 4 and set in the system/build.prop
It controls, how the device handles locking, usually it is set to 1, but, i think, it goes from 5 to 0, where 5 is "stay on all the time" and 0 is "shut down everything when locked".
You could try to swich it to 2 or 3, maybe it helps.

I got a replacement phone which is working fine now.
Thanks for the tips anyway

hmm got a 16gb one and the Sim keeps disconnecting even without deep sleep.
might need to send it back too. poop

Hi,
I got the same problem too.
Sometime, it's getting worse and worse so I have no other choice but to reboot the phone --> When I put my PIN code and press the validation button, the screen doesn't go to the main menu but asks me again about my PIN code. Infinite loop...
I cleaned the SIM card 15min ago and no problem since (fingers crossed). I read an alternative version of android solved the issue in one case but not always. I won't take that risk if I have to send it back to the manufacturer. Before I do that, could you suggest me something else to try ?
Many thanks for your help.
Best,
Valentin

I had the Nexus 4 since December and yesterday for the first time the phone asked for the PIN code and lost the connection to the network. And like posytryon I had to enter the PIN more than once (in my case it was "only" twice). This morning it already happened twice again. Never rooted the phone, stock Android on it. What is going on?

Why are you people so paranoid? I've never used a lock on mine. In all these years....
Just asking for trouble using sim lock IMO.

What kind of silly reply is that? Why is it asking for trouble using SIM lock??? And if you read through this thread, someone had the same problem of the phone not connecting anymore even without SIM lock.

I pulled my sim yesterday because I switched users now it says no sim I put old sim in same problem flashed new rom nothing...
(CRAZY TIMES)

I'd noticed the same thing, and insulating the SIM from the holder resolved the problem for me also.
I also found an app for monitoring and alerting if the phone switched back to asking for the SIM PIN, this might be useful for others.
SIM Locked Notifier - https://play.google.com/store/apps/details?id=org.slaytanic.SIMLockedRingNotifier

Finally put some adhesive between the tray and the SIM card. Worked perfectly for me too, no SIM problem for 10 days now.
Thank you so much, Lucker#1.
