Missing sim card?

Okey, here is a stange problem!
I purchased a used Tytn II today, and everything seems to work fine! BUT there is a BIG BUT, every time I restart my device it says that the sim card is missing even tough it is in fact in the device, then I have to take the card out reset the device shut it off again and insert the sim card!
Sometime it works and sometimes I have to repeat that procedure several times before it realises that there is a sim card!
Is someone else having this problem, and if yes how do you go around fixing this?
Or is my device simply broke?
Thanks in advance!

I posted this a couple of months ago - works for me
"Happened to me when I got a T-Mobile PAYG SIM last week to trial for data coverage.
Popped SIM in and worked well.
I then tried a Vodafone Sim and that was ok.
When I put the T-Mobile SIM back in - I got the message "no SIM found"
Tried Orange and Vodafone and they both gave the same message !
I was not convinced the SIM'S were making good contact - there seemed too much movement under the flimsy metal crossbar.
The solution to get the T-Mobile and other SIM's working was to insert a small piece of paper on top the SIM as you slide it under the metal crossbar.
This puts a little bit of extra padding on top of the SIM to help make decent contact.
I suppose the paper could be put on top of the crossbar instead to achieve the same effect but have not tried this.

Also make sure the sim is clean - use a pencil eraser is one suggestion.

So far so good!

Okey, I tried to put some paper between and so far it works!
The strange thing is that I did not even try to replace the card, I just rebooted the device and the sim card was missing!
Cant figure that out!

Hi there,
I just wanted to stop in and say thank you! I have been beating my head against the wall for the past two weeks over why my Tilt kept losing its network connections in perfect conditions and constantly telling me the SIM card was missing. Reseating it only worked once in a great while, but slipping a piece of paper in there seems to have done the trick nicely. I did notice that the contacts on the Tilt dig grooves into the SIM card contacts - do you think perhaps this is the problem or is this common among cell phones?

Thanks Bigdish, worked for me too.

thanks a lot for the information, putting a paper on the SIM resolved the issue in my tytn II, I was so nervous when I saw sim not found in my phone and tried to do reset several times and also repeated the ROM upgrade several times and finally a piece of paper served the purpose thanks....

The Sim Card Is Missing

this is not a repeated topic
i searched all the web for solution but i couldn't find any
my At&t tilt is unlocked it works perfectly for short time ever few resets
else, it give the message "the sim card is missing" you can srtill make emergency calls if your provider supports it
i tried every thing, unlocker, hard spl, all the tools herebut nothing worked
can any body help?

Any chance the SIM is loose in its mounting?
It looks to me like there is a bit is wiggle space in the SIM slot.

did you try another SIM card?

One of my kaisers uses an old sim where a layer of laminate had been peeling away. This meant that when I inserted the sim, the loose laminate folded back on itself and acted as an insulator between the brass phone and sim contacts. So I removed the offending laminate but still had the occasional "no sim installed". The problem was that the sim was now a little thinner. I applied pressure to the centre of the metal belt that holds the sim in place ensuring that the contacts were "always together" and have not had any problem since.
I hope this simple solution works for you.

ANother thing you can try is rubbing the gold portion of the SIM card on your jeans or clean it off with a pencil eraser. I had that problem, and it stemmed from a little corrosion or crud building up on the face of the SIM card, and by rubbing it on my jeans it cleaned the corrosion off and the sim was able to make good contact with the points in the card slot.

Sometimes sim cards go bad. I've had about half a dozen go bad out of about 40 devices that I have supported over the last couple of years. AT&T acts like it's a common occurence and no big deal. I just take the device to one of their storefronts and they replace it immediately.

is there any way to restore every thing it's initial conditions?
i'm getting frustrated here

Did you try unplugging the battery, put the sim card and then reinsert the battery and start?

hey just wanted to say thanks. i just added a piece of paper between the card and the metal part and it worked. just wanted to say thanks.

I had the very same problem today after putting a brand new sim in the phone.
Found that I had put the damn sim in the wrong way round. Oops.

I had the exact same problem and in my case, putting a piece of paper in did not help at all. I had to get a brand new sim card.

i had a similar problem. it couldn't read my sim card, but read my gf's tmobile sim card and her phone read my sim card fine. then i next day i took it to an ATT shop, asked for a new sim card and it worked perfectly fine now. even the guy from the shop couldn't tell me what is the problem, he said, it happens every now and then.

Sim missing ? Any ideas

Hi
ive got a problem whereby my phone stops recognising my simcard and i can't
get it to recognise it unlless i hard reset
the hard reset works for about 3-4 hours and then it stops recognising it.
( during the 3-4 hours i don't move the phone just so it HOPEFULLY proves it isn't hardware.
Any Ideas
thanks ben
( it is on 02 and i have tryed other 02 cards and an orrange card )

I know this has been covered a few times and can be found easily using the search...
Most liklely it is hardware, as the ROM does not really ever affect that. One thing to try is when you open the sim card door, there is a metal bar that goes over the card and holds it in place. Remove the card and press down on the tab untill it touches the golden tabs below it. Then put the card in. This should put pressure on the card and keep it connected. If that does not work, you may need to replaced the sim card reader

Hardware definitely. Had the same problem and luuckily had extra parts. Swapped it out and works like a charm now.

Swapped what out ?
The SIM card reader ?
Where would I get one ?
Who would install it ?
I have this issue and I want to go back to my TyTN II.
Thanks.

I wouldn't count too much on the hardware. When i got my Kaiser yesterday (slightly used) it recognised every simcard i had in store, except my own, which i wanted to use. Simcard in different phone (a soaked Herald, but somehow sometimes working) told me the sim was fine. So i transferred my contract to a out-of-the-box simcard from KPN-NL, and that one somehow worked. I didn't really bother to have another thought about it, but is it a known hardware issue then?

[NEED HELP] kaiser lossing signal and can't read simcard

i've try to find similiar problem and i can't find the answer...
guys my kaiser can't read my sim card
i lose it when i use android, so i use wm 6.0 again...
the signal got well for one night, but since this morning it never read my simcard...
i've use mtty, change radio, use wm 6.1, wm 6.5 and it still can't read my simcard...
can anybody help me with this problem??
about my english please forgive me, i'm still learning...
thanks guys for your help...

Hey, I can't really help you. But the same has happened to me a few times: every time, it eventually started to work again after some time. Could be a few hours, could be a week - so be patient. I have no idea what the problem is, but at some point it started working again after I put someone else's SIM in my phone then switched back (both SIMs were of the same provider). Good luck!

you are not alone
I have exactly same problem with you.. since 2 days ago my kaiser won't read any sim card.
Actually it had happened a few weeks ago, my kaiser fell from my hands and hit the floor. After that, my kaiser stop reading sim card, but after one night it started to works again just like Cerberus_tm said.
2 days ago it happened again I really careless.. but this time until today, my kaiser still won't recognize any sim card.
I have done some reading in a few old thread about this case. I'm not sure myself but based on those thread, I can conclude that the problem could be because of the sim card doesn't make contact with card holder, or there is a problem with the flex cabble that connecting our sim card holder.
FYI, if you are interested in fixing the flex cabble, the price is about 700.000 IDR here in bandung.

Fixed my sim card no work issue
It was intermittently working so I knew I was close and yes the poor Tytn II 8925 has been dropped about 1/mth thanks to the stupid sprint magnet case that always seems to let go after I get up from a chair. I tried raising the gold contacts that touch my sim card, that did NOT work. I tired putting one layer of masking tape on my sim card, that did NOT work either. I even got a new sim card from my carrier $10, that did NOT work. Finally I tired pushing down on the steel house that holds the sim card, that worked!

Just put a piece of paper on the back of sim card while inserting it into the sim holder, my kaiser suddenly started acting like this, I slid a piece of paper at sim's back and now its working pitch perfect

Sorry Sim card error back (not fixed)
Seems to work after battery removal and 3 restarts, getting ready to dump the phone.... It works for a couple of hours, then all of sudden sim card can't be read....can't live like this.

perhaps by way of radio uprgade you can handle !! You can get more information at http://forum.xda-developers.com/showthread.php?t=393182

perhaps try reinsert the sim module if you are ok to open the device up? or replace the simcard module flex cable
