HTC One X SIM Card Failure Video

Hi Guys,
Just wanted to share a video of my HTC One X with its SIM Card Disconnection fault.
(XDA Won't let me submit a link as I haven't created 8 posts yet...)

It looks like a mechanical or contact problem. Have you tried another SIM card? Did you cut it to microSIM yourself?

Yes - I've tried multiple SIM cards and other SIM card holders from my friends One X.

Then I would say it is a mechanical issue with the contacts inside SIM slot. You should try to get it replaced.

Yes that's what I think too.
I'm trying my best. The company I bought it from online were 'unable to replicate the fault' and sent it back..
This is why I created this to prove the fault to them. If they still won't replace I'll contact HTC.

I have the same problem with a brand new HTC one XL.
The SIM card is not detected by the phone after couple of hours of use and I have to take the SIM out from the phone and plug it back in.

same problem here with cuted SIM card but my brother one x is working fine with cuted sim also.

i have the same problem. time since i bought one x it has lost connection with sim three times. last time it was yesterday morning when i reached my hand to get one x and wanted to see what time it is, i saw "enter pin code".
i havent tried any sim card, cutted or not, since it only supports microsim, and i have only standard size sim cards.
could it be phone fault or perhaps sim fault?

according to baadnwz (from the insertcoin roms) it's a software issue, he made some fixes to the framework and it greatly improves the issue for me but not for 100% .

Had exactly the same problem, sent it back and got a replacement that doesn't have this problem. (before that I tried a lot of things, such as adding some tape to the simcard, but none worked).
BTW, this is not a software issue, it's a hardware glitch that occurs when flexing the phone slightly, like it will do in most pockets.

I had it happen even when it was just lying on a table and baadnwz did fix something, so it must be software....

Wait. So who are the people using carrier-provided microSIMs and who are the ones using cut SIM cards?

My car didn't start last week as I had a flat battery, my neighbours car didn't start yesterday morning so I told him it's your car battery as I had exactly the same problem. Turns out it wasn't he'd run out of petrol
Point is it is very likely that different faults (software and hardware) are causing similar symptoms.

I have the Intermittent loss of sim that comes back after a few seconds and I'm using a cut sim.

in the thread on tweakers.net (a dutch site) many people are. complaining about this issue whereas on xda it's just a few people. a while ago in holland many HTC phones on the vodaphone network kept rebooting spontaniously, others had their clock run weird if connected to network time and others had no problems whatsoever. anyway it turned out to be a race network/sim/firmware issue, my guess is this issue is something similar.

I have purchased a brand new HTC One X online, and is the same issue. It refuses to detect any sim I insert and although wish it was a software issue seems more like a hardware fault.

what were baadnwz tips for fixing this problem? searched the forums and couldn't find a thing.

I had this issue with my sim card seeming to lose contact. I'd randomly see 'no coverage' then it would come back.
I had a look through some of the forums, and tried the sticky tape fix, and that seems to have solved it. Fingers crossed
Mine was a cut SIM, and since the tape is on and making it a bit thicker it's ok
I still get what I see now is the usual problem with mobile data not working sometimes, but the sim contact seems fine

My sim is also cut. might try tape but i heard it would be difficult to remove the sim in the future.

SIM Card Removed

After installing CM 12.1, I started getting the "SIM Card Removed" error pretty frequently.. it's very annoying. I've been doing some research, but I can't figure out if it is software or hardware. Please advise.
By the way, I have had this problem on CM 12.1, CM 10.2, and Resurrection (which is based on CM 12.1). I will be trying the Google Play Edition later today, and I will go back to stock 4.4.2 if I get the error on GPE. I'll update on my results.
UPDATE 10/5/2015: I found a solution! If you take a small piece of plastic (I used a piece a little smaller than my SIM card) and tape/glue it to the inside of the frame, directly on top of the SIM holder, it applies enough pressure to keep the connection. No more error! It is a hardware, not software issue.

It's a known hardware issue; contact your carrier for a warranty replacement.

Thanks for letting me know! I ordered the replacement part on ebay for $3. I'll update with my results.

In many cases its not the fault of the sim card holder, but a poor connection at the ribbon cable connection to the motherboard. Several folks said replacing the holder/cable didn't fix it because the problem is due to the motherboard part of the connection. Several reports suggest pressure on the connection where the ribbon meets the motherboard, by bits of foam or whatever, can remediate the issue.

Thanks for the info! I will repair the connection itself if the new holder doesn't fix the problem.

I get the error message off and on, but for some reason when I loaded CM 12.1, it triggered the error message continually. Had to go back to stock. I don't know why, seeing as it is a hardware issue, but my phone sure didn't like CM!

There is a long thread with many solutions offered here :
http://forums.androidcentral.com/sa...4-major-problem-sim-card-not-detected-11.html

Just thought I would post my final solution - I have been dealing with this error for a LONG time! I dropped my phone last week and it wouldn't recognize my sim card at all. Lots of searching, watching lots of YouTube and this is what finally worked. I had to remove the back cover, then remove the back of the phone. I used 2-way tape to tape a small piece of an old customer rewards card (others have used a piece of a guitar pick, but I didn't have one) across from the connector for the sim card/sd card reader on the inside of the back of the phone. Finally, no more sim card error.
I tried to put foam inside the back cover, etc., but it wasn't until I actually took the back off the phone and applied the fix that the error finally went away.
Hope this helps someone!

I found a solution as well, thanks to these two posts. What ended up working for me was to cut a small piece of a plastic card and glue it to the frame directly above the SIM holder (on the inside of the frame). I have been going for over a week now with no error!

Awesome thanks having same issue for months now.

Phones radio or something is acting up.

Not sure what happened, but I've been using my S4 good. Out of no where it started acting up, freezing on me, etc. It's on latest firmware, 4.4.4 OK3. When i look under about phone, and check "service state", it would randomly say, "in service" then "radio off", "out of service" then go back to "in service". Also had/have a problem (haven't tested it for a good while yet, had old sim in and it gave problems, now using new sim, still did it one time atm.) with the phone saying "sim removed" or etc, like it cant find a sim? (weird part is my old sim works fine with other phones, my phone kept losing sim, sim no found, etc)
Weird, never had it happen, bars would go from 2 to 4-5, then drop to 1-3, or to 0 and go out of service. I did factory reset, but ofc it only went back to OK3 stock, tried to use previous modem that worked for me before problems started happening like NK2 modem, nope...still problems, so I flashed OK3 back for now. If i have good bars, and turn on mobile data, it would go out of service completely until i shut it off, cant use my mobile data. Anyone know what's the problem? Phone right now running with minimal apps installed, if you need more information, just ask. Thank you! in advance.

Used the phone for a day with new sim, still has problems freezing up on calls(screen), says sim removed...device needs to restart, etc. Would Flashing older Firmware to like Nk2 solve this? I havent had problems on older ones, but when i got OTA, used for couple months and having problems now. Service keeps being circle with line thru it, when u try to make a call it would say "cannot connect to network or registered on network", dbm was -113(usually -100-115), and asu was 0, when service cuts off, keeps finding service then loses it all day, finds it, then make few calls, and loses it, keeps searching for it. Would flashing OK3 firmware solve it? Maybe OTA went wrong? Idk...or maybe go back to a stable rom 4.4.2?

Is it possible the sim reader is damaged?

Not sure how it could have been damaged, it was always in a case.(guess i saw a video where a guy said they sometimes go bad on gs4's) Phone already been used for pretty good 1.5-2yrs. Phone freezing up, etc would result in a bad sim reader? Anyway to test that it really is a bad sim reader?(if it did go bad)

Was the sim card used with a sim adapter?
I suggested the possibility of a damaged SIM card reader because of the "sim removed" error message.

The previous sim that was origionally used in GS4, was used with sim adapter in an older phone that needed a standard sim, so this micro sim was was in adapter in an older phone, worked perfectly fine on Gs4(no sim adapter, just the micro sim), i even got a new sim card off ebay and changed over my number to new sim, and still phone is freezing up on calls, using it normally now, the signal would find the Carrier, then would lose it so many times, then tries to find it, then loses thru out the day, it's annoying as hell. Never had the problem of losing signal, having out of service sign(circle with line thru it), had good service everywhere till now. I even did a factory reset, started up phone up new, still problems with "sim removed" device needs to restart time to time, losing and catching signal a lot, or no service. Anyway to test/find out it really is a bad sim card reader? Just don't want to do 100's of things and it's not it. Phone it used for work ofc. Let me know if i should try anything, before buying a sim card reader, if it really is the problem.

How is the sd card reader? Both readers come as a single unit and they are not too expensive on eBay.

Not really sure, how the sd card reader is...Haven't really used it, as i didnt really need it. I could try and get back to you on that. Yeah, i checked on ebay, they r like 5$ or so, but still the hassle of replacing it, and it's not it. I'll get back to you how sd card works...etc.
Edit: Just tested my brothers Sd card with tons of pictures and videos on it. Put it in my phone, can easily look thru pictures and videos, unmounted couple times, put it in, works fine without any problems. Any ideas?
Also read online about sim error problem, and lots of people are saying it could be a hardware problem, and need to apply pressure to the ribbon of the sd/sim card.
Phone is working fine without the simcard inside, good bars, sometimes it goes low/no bars, or out of service, but still less then it is with a sim inside for some reason.

This is a known issue with the S4. Mine did the exact same thing. I have researched this and tried every fix under the sun, and nothing worked. I even bought a new sim card tray and replaced it. Nothing worked, and I babied this phone. My wife and daughter also have the S4 the same age and theirs are fine. I gave up and bought a new phone. Wish I could give you better news.

So you pretty much saying it's a hardware issue and nothing can be done to solve it? Thought maybe flashing older firmware or something might solve it, perhaps a hiccup in OTA update or the latest patch that could've caused it. Kinda sad to just throw it away when it was working soo good.... =/

OK, one question? How is the inside of your phone that damaged and beat up? Jeez man, take better care of that thing.

It is sad. And if you google the problem, you'll see a lot of S4 owners were mad that Samsung doesn't acknowledge the issue. I think somewhere on this site you'll find this subject covered in full. Some of the fixes work for a short time, but ultimately it is a hardware problem. Some think it's the NFC chip that is right under the tray (supposedly) that heats things up and causes the malfunction. Whatever it is, it has turned my S4 into a infrared remote for my TV, a Chrome caster for Netflix and Hulu, and an iPod Touch!

Rofl....At least you're still putting it to a good use It was a pretty good phone too rofl. Have you tried everything from putting a piece of foam(ear plug) over the ribbon for the sd/sim that lots of people talked about, etc? I guess if there is no real solution, I'll get get a new phone, prolly an iphone or w.e., had an eye on Gs6 Active cuz of long battery, durable, dust/water proof, etc, Gs6 is nice too but I'm in construction, and it's always in my pocket, need something that can last, and you know, keep a good charge while using everyday use like gps, listening to music, etc. What did you go for after your Gs4 stopped on you?

Yes sir, tried them all!
I like a large screen, The S4 was the first phone I owned that had a screen larger than 4". So, I had to go even larger now. I picked up an Nexus 6 when they dropped the price after the 6P came out. My wife and daughter still have their S4's, so I keep up with the latest here for them.

damn shame... i just dropped to 4.4.4 with the NH7 kernal and modem set... still nada. I had a bit of luck with the separating the right side of the phone trick for a bit, but even that doesnt work anymore... I have a note 3 that im using for a daily driver... but i really find its too large for my taste. The s4 was pretty close to the perfect size for me. Prob gonna scoop up an S6 in a couple weeks. Ill keep it around as desk clock prob and a back up for when i drop and smash the s6 to pieces. I swear the wifi and bt were working till i installed the JDCTeam MM build back in december i think. Which made me think it was software related. Ever since then its been doneski... But tbh at this point, everythings pointing to hw issues...

this $#!T is weird...
I admit defeat...

Well, looks like i kept getting the stupid sim card removed often even with w.e solutions i tried to use. Then out of nowhere my usb port stopped working altogether(cant charge my battery now lol). I give up, don't want to waste money into usb port, then something else falls apart rofl. My other Gs4 also worked for 2.5yrs or so, and died. R.I.P Galaxy S4's lol. Don't think they were built to last.

LG G3 D850 "SIM Card Removed" Problem After Marshmallow Update.

After downloading marshmallow on my LG G3 D850 everything seemed to be in order for a good week when one day randomly in class my phone gives me a "SIM card removed" notification. I shrugged it off thinking I can fix with a simple restart but the problem priests. I'm positive it can't be a problem with the pins or the SIM reader because at random reboots it would detect my SIM card but either read it as invalid or it ends up working for some time and then the problem comes back up. I tried factory resting it a countless amount of times and I figured out when it does work , I can't download apps or use things like Bluetooth or airplane mode without the problem coming back. This is very annoying and I reached a breaking point, is there a way to fix this? I can't seem find a method to root D850 on marshmallow meaning I can't downgrade. Does this mean I'm screwed?

Same issue
I'm having the same problem, but my phone started showing the "invalid SIM" or "SIM removed" messages while still on Lollipop. I updated to Marshmallow and it persisted, did a factory reset and it's still there, only thing i haven't done is rooting the phone, i've been having this issue for the last 3 weeks, it used to sporadic but today my phone has restarted over 15 times and now it's pretty much a brick.
Only thing that seems to make the phone stable enough to use i to switch off the data network and turn on wifi, i can make calls but as soon as i'm out of wifi range, all i can do is make calls...
I'm pretty new to this but I think this has to be a software issue, i already took my phone in and the repair guy told me, after cleaning the phone and checking the contacts on the SIM card tray that the LG G3 was coming in more and more with the same problem with no repair...
Checking online it seems more and more people are having this problem lately.... coincidence?
Has anybody figured this out????

"Sim Card Removed"
Same issue here on my lg g3, D855

Im also having the same issue have you found the solution

Has anyone found a solution to this?? Its happening to my phone

Same issue D855, but I use the marshmallow version since the first release.
The problem emerged without notice.
What happen?
Notification and message, to screen, "SIM card removed."
The phone automatically reboots.
Snap the signal for a little while, everything works for a little while.
Suddenly loses the signal and does not hook more mobile radio signal and I have to restart.
Sometimes it does 4-5 times a day, other times remains in use 24 hours without giving me any problem.
Already warned assistance, I have to send him assistance in their view, my warranty expires Oct. 6 (no contacts, because they are in plac, cleanest and most sim warheads)
Tested official ROM and also mod (FulmicsROM).
if you look for the "SIM card removed" message there will be other topics also on XDA for G3

I too started having this issue since yesterday. Any solutions?

I have the same problem for about 5 days on my LGG3 D855. My phone is rooted and running fulmics 5.3 ROM for about 5 months. I did a full recovery and I even changed my sim card but the problem is still there. Does anyone knows what's the problem?

Has anyone managed to fix this yet? I have a D852G with Vidéotron. I find it strange that this is happening right when my 2 year contract with them is up. Has downgrading the phone worked for anyone?

It seems to be an ongoing issue related to hardware. Most readings I've done from other forums, reddit, etc all point to the sim card reader beginning to fail. I can't for the life of me tell if that's the issue or if it is really software related.
I've opened up by device and checked the soldering connection points, everything seems fine (to my untrained eye). Putting a small cardboard/paper cut out in the sim card slot seemed to help, but otherwise, jeez.

same here. but on LS990. Tried KK, LP, MM roms. but no help. I don't know whether it's hardware related.

Same here... Tried MM and now nougat, same problem..
Will switch sims today and see what happens

I'm suffering with this issue also. D855, fulmics 6.7.
Mine seems to go into "No SIM Card -Emergency Calls Only" sometimes just randomly when the phone is on, but almost every time I switch my battery it does it (bloody stupid piece of crap). It's so annoying as I'm eating 5-10% of a freshly charged battery by frantically restarting my phone till the sim card becomes active again. I think it may be hardware related but this issue arose after the MM update for me. I can also report that my SDcard port doesn't work (keeps randomly ejecting) and hasn't worked for nearly a year now. But sim card still worked fine.
It's forcing me to feel the need to spend money on a new phone. Money I don't have right now! Money I don't really want to spend as my phone, other than that, is perfectly fine. Anyone had their sim+sd card reader replaced and still having this issue?
Let's bust this bull**** problem!

I gave my phone to a repair center and checked the sim tray. It's all good. They suspect the signal ic must have the issue. Furthermore they said even though i replaced it, chances of getting a roasted ic is still high. I don't know what to do.

You sure? Maybe you meant the G4? G4 has cpu problems

I've been having the exact same issue guys ??... and again phone surface temperature rises as phone keeps on rebooting to detect sim card... Anyone with a clue or solution to this yet???

My 2.5yr old G3 (D855) always on Kitkat 4.4.2, also suddenly had this problem, at first I thought my 18yr old sim card finally bite the dust, but then when I changed to a brand new sim, it happened again. Then I factory reset the phone, worked for a few days, then it happened once more, so pissed. Maybe it's just me but it seems like it's an international trigger or something to make all G3 users it's time to change a new phone. Going to buy alcohol later to try clean the contact points to see whether it's a hardware problem.

so guys, i totally unscrewed this G3, opened the metal acess doors to both the cpu and Nand Flash memory and wiped with methylated spirit... since then, my phone has not said anything about an invalid card

[HELP] Slot Sim 1/2 & Vibration mortor doesn't work

Hi,
recently my zenfone 2 got very hot in my car, I used it as GPS and charged it during the trip.
And BOUM, I was writing a message and the Sim card suddenly stop working .
So I tried the Slot 2 twenty minutes later, it worked for 1-2 minutes.
I thought it was a ROM issue, so I switched to a complete new ROM (the lineage one) but that not solve the issue. I just see that the vibration motor doesn't work either .
Finally, I think it is a material issue... I already bought the Sim slot card piece replacement for changing it myself, but how can I know if this will be enought ? Maybe is this a little part of the motherboard which is dead ? I don't want to desesperaly try to repair my phone and loose the guarantee (I expect that I already loose the guarantee with the unlock bootloader/root).
If anyone had a similar experience, please share it with me :highfive:
Thanks

I thought it was a ROM issue, so I switched to a complete new ROM (the lineage one) but that not solve the issue. I just see that the vibration motor doesn't work either .
Finally, I think it is a material issue... I already bought the Sim slot card piece replacement for changing it myself, but how can I know if this will be enought ? Maybe is this a little part of the motherboard which is dead ? I don't want to desesperaly try to repair my phone and loose the guarantee (I expect that I already loose the guarantee with the unlock bootloader/root).
If anyone had a similar experience, please share it with me :highfive:
Thanks

well here may be two scenario. A. too much heat damaged the components. B. heat caused the components to desolder.
take little soldering paste and apply heat to components especially ICs

Ok thanks, I'll try it before open it and install the new card slot... What do you mean by ICs ? And Do I have to unplug the sim card slot to apply the paste ?
Thanks :angel:

i didn't get you point. you do not need to apply paste to sim card connector. i meant to apply paste on motherboard components. like processor, power ic etc. better do not heat the emmc though
