at&t tilt: stops detecting sim card when slide IN. works when slide out

i have had no problems before, i flashed a couple roms in it before, but in the end, i kept very lightly modded rom very close to OEM rom for the tilt that i got from here. all was well for months and months.. until now.
i noticed that the phone will lose signal. and not detect a sim card anymore. at first i thought it was sim. so i tried it on my other tilt (i have 2) and i determined that its the phone.
if i restart it, it works for about 1 min or less if im lucky.. then i have to to go comm. manager, turn off phone signal, and turn it back on, usually, that does the trick. but now, that wont even work anymore.
the only way to get the sim recognized again is if i slide the phone out, go to comm. manager, turn off phone and turn back on, and LEAVE the phone slided out. once i slide the phone back in, it will not detect the sim. ive tried diff. spl, different roms, and searched before i came back here.
ive had it for over a year, have broken the screen and messed up keyboard by closing hood of my car on it,
but ive fixed it. and that was long ago. maybe this new problem is because of this. if someone had similar problems, let me know what you did. or if anyone can point me into the next direction. i guess ill have to crack it open again.

I had a similiar issue where my phone would turn on ok, then lose signal and then get the no sim card error (dialer screen). What I ended up doing was taking a piece of tape and put it on the back of the sim card then slid it into the holder and locked it. (It was a thick metal tape, if you use scotch tape I recommend using a few pieces). Once I did that I havent had another problem with it. Its a pain to get the sim out of the phone because it ruins the tape but I would rather deal with that than not have my phone work correctly.
Let me know if that works for ya.

i see. so it seems that your problem was that the sim shifted out of place sometimes... i will try that. hope it works. its so odd that my sim card dissapears when i close my tilt

I just recently had a similar problem and I finally figured out it was a bad contact with the SIM card. you can either use the tape trick, or if you have a steady hand, take a thin object (such as a paper clip or glasses screwdriver) and very gently lift the contacts up underneath of where the sim card goes. they may have been pushed down due to abnormal pressure exerted on the back of your phone, I think that's what happened to mine.

thanks for your help. the sim contact issue was the first thing i suspected, AND tried. i used a needle. i raised the level of each of the 8 contacts making sure the sim will make contact with each pin. but the problem remains.
i will try this again. to double check. i will respond with the results

i tried pushing the pins up a little bit again, i still have the same problem
*but now i have an update, it seems that the sim card stops being detected right before i actually fully slide the phone back in. for examplle, before the slide-in tone is played, and before the screen tilts back.
i already took it apart for a look inside, everything seems fine. and i dnt really know wht to look for.

Hi,
was reading about ur issue, just tought on jumping into the wagon, I suspect it might be the flex cable that connects the sim to the motherboard, if there is such cable, i haven't opened my kaiser yet but my Pioneer car radio has this flex cable issue when the drive is closed the screen turns on and the whole radio but as soon as you press eject (the face will scroll and unveil the cd slot) the radio actually turns off and i have to move the face back to its original position in order to work. At the end I took the flex cable out and 1/4 of it was teared, in the end I had to order a new part

thanks so much for your help. i guess there is nothing left to do but to take it all apart. somewhat blindly. at least i know what to look for. bad cables, contacts... im clueless as to whether it can be a bad grounding issue? or a short. i dnt know. i guess i may be the first one to experience a problem like this on a tilt.
so i will do my best to get this problem resolved. and maybe include some pictures if it is intereting enough

my tilt totally stopped recognizing the sim.. it first happened when i dropped it and had to keep it open to keep contact.. then i was sitting with it open and tilted up, it fell and closed somehow and now the sim isnt there at all... i guess something is disconnected or whatever, im afraid to take it apart, but its either that or a paper weight.

New Sim
I had a similar problem. My sim card would disappear on occasion then one day I woke up and no phone. Just an annoying sim card not installed message. Checked the phone by putting in a known working sim card and it was fine. Called ATT for a new sim card and now my phone is working. Try a new SIM CARD.

For the original poster -- that fact that it works when the keyboard is in one position but not the other indicates that it is likely a bad flex cable.

Agreed
Its most likely the cable. I used a new SIM, the extra pressure trick, cleaned contact, etc on mine yesterday, but the problem remained.
I got a used Tilt from Craigsliist , reusing the SIM and case, and it works great.

i wonder if anyone has bought this item before and if it works? upon research, i think our problem comes from the sim card flex and ribbon:
http://cgi.ebay.com/HTC-TyTN-II-P45...AU_MobilePhoneAccessories?hash=item2a05bd88c4

It definitely comes form that ...but the repair cost is more than the replacement cost..so why bother with repairing it?

Hey, I'm having the same problem, my phone just out of the blue after a year of use says no sim card. My card is fine in other phones, and no cards work in my phone. I tried the pressure thing and cleaning the pins, but no good. My next option will be a hard reset/ wipe the phone and see if that clears the problem. I'm not optimistic after reading the thread. Did any one have luck with one of those Kaiser Flex Sim Card Slot Repair Parts that loller90278 mentioned? If so, I would rather spend $16 to fix a phone that has worked well up till now, rather than spend $100 on an unknown used phone. Still I don't want to bother if it's not going to work.
Thanks

well well...i'm going to have to join this "club" of affected kaiser users
my kaiser just started misbehaving last night. i bought it brand new exactly 1 year and 11 months ago
i took good care of it, barely ever tilted the screen during my almost 2 years of use. the current behavior is that when the keyboard is closed, the sim is hardly ever detected (1 out of 10 times perhaps). when the keyboard is opened, the sim is fairly regularly detected (9 out of 10 times perhaps).
i am not going to bother with investigating the possibility of a software problem because of my observations. given all the threads i've read about this issue, i am convinced my sim flex cable is either loose and/or broken.
anyway, it seems the kaiser's flex cable is just not built to last much longer than 2 years. if i can have it repaired for up to around $50, i'll go for it...if not, HD2 here i come!

just wanted to follow up on my own post above.
i just got my kaiser back. its been repaired
the dude cannibalized the main flex cable and sim assembly from a tilt and transplanted it into my tytn2. BUT! there has been an interesting side effect...because the tilt does not have a front cam, my guess is that its flex cable is unable to carry the signal of the front cam in the tytn2. so now my front cam is no longer detected. the camera app shows no icon to switch to another camera. the icon is blank!
i figured i could either have a kaiser with sim problems or a working kaiser with no front cam. i chose to keep the flex cable from the tilt because there is no 3G in my region and i hardly ever used the front camera otherwise.
long story short, my kaiser is back in business!

Similar problem !!!
Hello mate, .,. the problem in you case is the connecting ribbon between the keyboard that holds the sim card beneath it and the screen. I recommend u to replace the ribbon that connects. Its around 40 USD and that should do the trick.
Cheers !!!!!

Fix for No Sim Detection Problem!

Ok guys I had been without my phone for about 2 weeks due to it not detecting the sim card. After replacing the sim card, as well as the slot and many other parts, I thought the only remedy to fix my phone was by replacing the main board. Through research and having the additional sim slot by my side, I came up with a great idea that finally worked! This is what I did. First, open the sim slot door and locate a tiny black switch, this is the one that is controlled by the switch on the outside. Push it up all the way and power up the phone. Hold press firmly on the sim card against the phone, with the outside door open. Wait for the phone to boot up and the green light to flash, which means it is getting a signal, then you can release your grip and close the door by locking it. Everytime you reset the phone you will have to follow this procedure, but at least the phone will work. I am thankful that I came up with this idea because it saved me from having to buy a new phone. I believe the problem is that the outside switch is not fully catching the inside one, which is why the sim isn't being detected. Hopefully this resolves everyone's problems, because it sure worked for me! Let me know if you have any more problems.

Wow no responses? After all the problems people were having with sim detection? Please post feedback because I was curious if this worked for others as well. Thanks.

id help u out but i had 2 tilts and just fixed this problem of mine today, i just changed the part of the phone with the sim card holder on it and it works perfect.

Awesome!!!!!!!!!!!!
I have had an AT&T Tilt for about 6 months with this problem, i just read your post today and that totally fixed my problem, thank you so much!!!!!! Although in the down time of the one Tilt I purchased another one from a friend, oh well now i have two working Tilts, thanks again!!!

worked for me
i just have a small square of cardboard stuck to my sim, then the door pushes the sim against the contacts, but same idea as yours really. but this problem started for me when i replaced a smashed screen so i had assumed i shifted everything a little in the process of putting it back together.

works
i tried your method and that better than holding that door, thanks for the suggestion!!!

Glad to hear it has worked for you guys.

Lifesaver
Flashed a buddy's phone tonight. Spent three hours trying to get his phone to read his SIM. Found this thread and your advice worked like a charm. Thanks

No problem. Glad to help. I just wanted to help all the people who were having this problem so they didn't have to deal with what I had to deal with and be without their phone for 2 weeks!

Fantastic this Worked!!!!
This worked straight away. You ought to be congratulated. Ingenious. All these other threads I checked couldn’t find the solution. They talked of dry magnetic head spray cleaner, deoxidizing boards, flashing the phone etc. With some saying success after a few goes. Its kind of funny that what might have been happening for them, is that constant opening & closing the simm card cover in their processes probably inadvertently fixed prob by pushing switch in enough. Whereas your solution goes straight to the problem & solves it. Hilarious. Thanks Heaps Tilt Fanatic. Nice to have my TYTN II back up.

hi guys,
i got HTC tytnII/kaisser over a year ago,
and now i got this problem "sim card is missing",
i tried to put some paper and it didnt work,
try anything in this forum and it didnt work...
almost frustrated and thinking of put it on a cupboard.
anyone have another solution?
thank you

No sim card! Help please.

So basiclly my g1 doesn't accept any kind of sim card at all. My sim card used to work but now it doesn't. I tried changing sims already like alotta times but still it says "NO SIM CARD" when there is one. Everything works perfectly fine except for the sim card part. My phone isn't rooted. It's pretty stock. Can Anyone help me?! Please!?

Its a common problem that is occuring since a couple of months... Im having the same problem except mine recognize my sim card from time to time and then I loose signal and the sim card problem occurs again... Nobody on the forum know what to do about it so Im clueless about it...

May be hardware, not quite sure. You might want to get another phone.

My friend had this problem after water damage - he got lucky and warranty replaced it. I would guess it's a hardware problem as well, so your best bet is a new phone or see if you still have a warranty.

Yeah it used to happen to mine too but now it doesn't recognize at all. I have no idea what to do. I love my G1...

the answer is, hit T-Mo up on your warranty..... or buy a new phone....
im on G1 number 7 or 8.... T-mo keeps shipping em out under warranty

Holy ****, bro.

its the sad truth....
but it has actually been benifical...
T-Mo's warranty policy is that you get another year warranty if the phone is replaced with a NEW phone, and if it's replaced with a Re-Furb then youi get 90 days, or the remainderof your existing warranty
my frist 3 phones were NEW replacements
and after that i got Re-Furbs
i was told this by a T-Mo warranty repair tech, on the Employee line, as i used to sell t-mo at radioshack....
also this was confirmed by checking my warranty expiration date (t-mo MUST provide this date on your request) as it MUCH later than 1 year from my first purchase....

I see how that could work out... I would just be so pissy having to wait for a new phone over and over. Unless they replace it on spot.

well with the risk of continued thread jacking, T-Mo cross ships replacements, as in you get the newone before you have to resend the old one...
you have 7 days from the date your new phone activates on their network to return the phone, just has to be postmarked by that date (scanned into UPS's system)...
plus if your phone is totally BORKED, you can request a loaner from a local store while you wait the one or 2 days it takes for the replacement to arrive
also at this point i'll probably ***** and moan next time it breaks and try to get a free MT3G slide outta em on my next replacement..... they tried to give me a Dash 3G last time, and i told em to shove it...... (i want a damn HTC android phone, with a keyboard,1Ghz+ preferably, but if its free i'll take the upg to a MT3G Slide, no contract extension ofcourse )

[Q] Same problem, SIM recognition is sketchy
I've recently been having the same problem...
The phone, HTC Dream (EBI1) from Rogers, sometimes recognizes my perfectly functional SIM card, and most other times does not. This has been happening for a while now, and usually a reboot or two would solve the problem, but now it seems like it has finally quit (I've been rebooting/powering off/battery pulling for the last 2 hours, and removing and inserting the SIM card). I've changed ROMs, (well between different versions of CyanogenMod but it worked fine with it before) and nothing.
The strange part is, after rebooting 10 to 30 times and it actually recognizes the SIM card, if the device is left on, it will continue to recognize the card... I live in an area of s*** reception, and frequently go in and out of service, I've enabled disabled 3G, WiFi on/off, and it will still work for days, UNLESS the radio is turned off for whatever reason (Airplane mode, or power off/reboot).
Basically my only hope is to pray to the G1 Gods that it'll recognize my SIM card, and if it does, then do not loose power for any reason...
If anyone has any info what so ever, please let me know.
Also, If anyone knows how to get a log of everything that happens from boot, I'd love to know how.
My phone is the HTC Dream (EBI1) from Rogers, currently running: CyanogenMod 5.0.7 test2
Danger SPL
RA Recovery 1.7.0R
HBOOT-1.33.2005 (DREA21000)
RADIO-3.22.26.17

Possible temporary FIX!
Okay, so as my last post states, my phone will sometimes recognize my SIM card after a bunch of rebooting... I've been rebooting a lot today (3 hours straight almost, with no success) and my battery was getting pretty low, which reminded me that usually when it starts working again is in the morning... weird I know...
I would turn off my phone over night and usually in the morning, within a couple boots, it'll work again, which led me to think, maybe for some reason, when the phone is too warm, it won't boot the radio properly or something strange...
Either way, I put my phone in the freezer for 10 minutes, took it out and booted it, WORKS!!!
Also, the battery was just about out, and the cold shortened it even more, it died, I plugged it in and booted again, STILL WORKS!!!
If anyone else has this "No SIM card" message, even though the SIM is good, try turning it off, sticking it in the freezer for 5-10 minutes and then boot... it's worth a try...
Like I said in the previous post, once it works, don't power down, so next time I run out of battery, I'm going to try putting it in the freezer while it's on to see if it fixes while running...
I know this sounds dumb, but it does make a little sense. I just can't figure out why it will keep working under all conditions as long as it has power to it?!?

You know this actually sounds like a hardware problem. Or possibly an issue with the sim card. Try going to your local carrier and ask for a new sim card. T-Mobile US charges $20 I believe. I had this issue and a new sim card solved everything. If the new sim card doesn't solve the problem then it's definitely hardware related. And if it's hardware related it MIGHT be why you're getting bad reception. It's a long shot I know but I certainly wouldn't recommend anyone putting their phone in a wet freezer! Anyone that does consider this I suggest placing it in an air tight container to keep it from getting wet. We don't want your leaking quart of vanilla ice cream messing up your phone.

Solved!!
Hi, buddy!
I have a samsung captivate and I was having the same trouble.
I'm brazilian and my sister send me the phone unlocked from US.
It was working for 5 months.
When I changed the SIM it has began asking me for the code(??!). It was programed for not asking PIN code so I got surprised. I typed my code several times until get the phone locked.
I spent more than 2 weeks to find the solution: Galaxy S Unlock, a free program available at the Market. It's necessary to root and install Busy Box (I installed mine with Titanium Backup).
Try something close to this for your device!
I hope this can be usefull!

Preorder. Already sent back!

Had Note 8 for 1 day then reception decided to take a nose dive. Phone kept searching for service, so I checked SIM, no damage. Reset phone, worked for 5 minutes then Searching again. Took to Corporate store and got new SIM. 5 minutes later, Searching. The SIM tray isn't exactly flush so not sure if that has anything to do with it. Contacted online support in morning. Went through a bunch of steps, no good. Software would not do reset with dial pad, stayed stuck on white screen , so leading me to think there's an issue with software. After hour online went back to Corporate store to turn it in. Now my new order won't be here till 15th.
Not sure what's more probable, SIM tray seating or software or combination of both. Anyone else have any issues?

Sounds like sim tray issue - I have had no problems at all - at launch they are all running the same software so shouldn't be that.

You must feel gutted! Took my Note 7 back and felt sick as a parrot. When the second Note 7 had to be returned I went into a depression! I was so pi55ed off, twice same situation. That is in the past but I know how you feel. We wait months for these devices, read every You Tube clip read every media bite then the day we get our new device it has to go back.
I am not going to say there will be lemons in every thing we purchase as that is not comforting to hear regardless of its truth. Again I feel for you and hope your next Note 8 will be fine. Please let us know how you get on.

Could've been something else wrong, like a bad radio. Good thing you found out on day 1 instead of day 91

I had a hell of a time getting my sim tray with sim and sd to fit right. Took me a good 20 minutes. Finally got it seated and have not had any reception problems so far.

mobile network missing randomly

Happened twice now.
Mobile network just stops, leaving me with the icon shown in the screen shots
Last time it happened I just powered off and back again..
On 371
L29
Anyone else had this happen?? Never happened before.
Could just be the age of the phone or the SIM card developing a fault but have never had a phone of mine go like this before.
Roll on oneplus 8 release, can't wait to get rid of the phone.

Use your sim on the second slot to see if the problem is fixed.
I had problem when i was talking on the phone the call would randomly drop out. this problem was more than a month and my sim was 1 year old. i cleaned the sim but nothing changed, when i used the second slot is working fine.

Must be the slot then.
I'm actually using a rebranded L09
So only one SIM slot.
It's been ok since the power off so will keep an eye on it.

Ye it's been happening more frequently, happens when I go out of range, ie: basement and then come back..
Might just need a factory wipe..

@StatikBlue
And as luck would have it...look what just happened lol.

Going to leave it, to see if it comes on by itself or if there's any other way.
Edit: it didn't, cleaned the SIM tray, blew into the hole (like it was the SNES days) and I'll see how it goes.

That's the symbol for no sim card and/or faulty sim.
Unless the sim is actually faulty, the most common reason is if the sim is dirty, as the contacts can corrode slightly over time (the same as your chip & pin credit card can).
Give it a clean with a bit of cotton wool and alcohol, or failing that simply rub the chip with your thumb!
If it keeps happening, get a replacement from your carrier (usually free) & if it then keeps happening it's probably dirty contacts in the phone....
Had it occasionally with different makes of phone over the years so not just a Huawei problem & you'd be unlucky if it's a faulty phone.
