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.

Thanks. Oh and no problem. Glad it worked for you. Just thought I'd give back to the community so people didn't have to deal with the pain I went through.

HTC TILT Sim is missing

Hey guys i have had a HTC TILT for a while. I stopped using it a while ago, but i tried recently and i did the HARD SPL installed a 6.5 rom did the radio as well, but i'm getting a "sim is missing" error, with any sim that i try. Are there any fixes to this? I'm confused, thank you

No offence, but, are you sure you're inserting the SIM correctly? I spent half an hour trying to figure that one out on a late night... .
If not that, then check the contacts are in the correct position and free from any dirt/grime.

I inserted the right way. This issue was happning even before i did the hard spl. But the phone didn't have this issue until like a year of not using it. I tried googling stuff i see many people had this issue too but i cant find the answer.

I had the same problem and had to replace the main flex cable which ran me about $30 on ebay. Everytime you slide open your phone the flex cable gets worn down and this can cause other problems such as it not reading your memory card and white screen of death.
But before you do anything see if applying more pressure on the sim card by putting a thin piece of paepr between the sim card and locking dor. I heard that this can fix it if it's a minor problem. Good luck man.

Being the phone unused for one year, maybe the sim bay's contacts gets oxidated?
Buy a dry contact cleaner in an electronics-store (sometimes you can get it at hardware too) but be sure it's the DRY type
Turn off the phone, pull off the battery and spray contact cleaner in the sim bay
Leave it evaporate (the greasy one doesn't evaporate... :-( )
Restart phone and check if solved....

[Q] SIM Card Reader

So here's my situation
While crawling across a rapids I slipped, dipped my phone in the river, and thought all was lost.
I pulled the case and back shell off immediately and it seemed all was well once I dried the G2 with rice for 12 hours. BUT, the sim card no longer would read. After getting back home from my trip I pulled the entire phone apart and discovered the reader looked a bit rough and the slot was probably shot from the water hitting it. SIM card works fine in my S3 mind you.
So where I am at is I have a new SIM reader on its way here to install in a day or so which I THINK should solve the issue. Im curious if anyone else has installed this component before?. Appears to be 6 solder points that hold it in and thats about it. Hell of a thing that the entire phone works flawlessly but the SIM reader shat itself. Never seen anything like it.
Any and all input or ideas are welcome.
Cheers

Did you end up installing it?
My sim reader always gave out and I'm thinking of ordering the part but haven't been able to find a tutorial for the replacement.

I too would like to know the result...

I did end up installing the tray. However, as I removed the contacts that were placed on the board itself and so when I soldered in the new tray there was two points which would not adhere. I ended up replacing the whole board in order to remedy things.
But, most importantly I confirm the board install isnt too hard and will work if you just make sure to properly remove the old tray and dont just pry it off. The prying will rip the contacts from the board and then the solder wont hold.

No Sim Card - Emergency Calls Only Error on Verizon

Mostly just browse these forums, and as you can see, don't post often.
Since about 2 weeks after I got my Nexus 6 directly from Motorola, I've been having intermittent issues with my sim card. It varies wildly in time frame. Longest I've gone without the message popping up, and losing connectivity is about a week and a half. I shut the device down, restart, and it's back. Sometimes it happens as frequently as within the same 5 minutes. As you can guess, I'm highly irritated.
First, I called Verizon and they were nice enough to send out a new nano sim. Popped it in an adapter, activated in Galaxy S3, and into the Nexus. Didn't solve anything, but at least I can rule out a faulty sim card.
Second, called Motorola to ask for a replacement. 5 business days later I call to ask where my phone is and I'm told that they don't have any "like-new" stock and that they don't know when they will. I ask for a refund to buy another phone and they say it will be 4-6 weeks.
Can someone smarter than I tell me if this is for sure a hardware issue? I'm guessing it is, and that it's specific to my device since I literally can't find anything on the web/forums about others having this issue with the N6.
Help is much appreciated, thanks.

Check your apn settings

provide more info, are you stock, custom rom, unlocked, etc.
You may need to try a nuke and repave to start fresh. After a week, something happened to my SIM on a custom rom and the fix is to nuke and repave and that includes userdata.
so back stuff up but only restore what you seriously cant redo, thats working so far for me.
GL

Can you advise what to check in APN's? (Sorry for the dumb question)
I was rooted running stock rom for a week, but unrooted and factory reset when I thought I was returning it to Motorola. Has had issues both ways.

Try hitting the contacts on the sim card with a pencil eraser.

mrbrooks .. i have a nexus 5 and i have this exact same problem .. leads me to believe maybe its software related .. started after lolipop .. havent been able to find a solution yet !

nexus 5 doesnt work on verizon(not fully at least). the op said that he ordered a replacement, which sounds like you should do, as the nexus 5 did have an issue with coming with a bad sim card holder on occasion.

worst part is that it is happening on an Replacement device after i RMAd my first nexus for a power button problem !!
i hope its software related and can be fixed .. because google is now refusing to rma this as im now out of my warranty period !
just to be clear im not on verizon .. im on a gsm carrier and have tried 4-5 different working sims
it latches on to network and works fine for a few hours and then just drops and refuses to catch networ k...
any other ideas ??
can the bad sim card holder be fixed or repaired ??

Did this ever get figured out for any of you? I have the same issue on a Nexus 6. It won't read my AT&T SIM card at all anymore, but knows it's in there. When I put in a Verizon SIM card, it see the card and updates information in the status section, but still says No Sim Card at top of screen. I am currently in the middle of getting a replacement from Motorola, but now I am worried this will happen on my next one too.

This just happen to me as well, google knows nothing about it, neither does motorola , they are sending me a replacement hopefully that fixes the issue.

I just got out of the shower and suddenly had the "no sim card" message. Restarted the phone, still nothing.
Removed the sim card. Put it back in... Now I have data again. Wtf?

I just noticed this running chroma. It always happened on boot and always went away. Never seen it stock unlocked rooted and tweaked with things like the Motorola command center, tethering, and such.

I have just got a N6 today and mine seems to be doing this. Have you guys had yours replaced?
Eager to know if i need to send it back or if its software. The sim card works fine in my s5.
EDIT: it looks like I can make it do it. If i type really quick , the vibrations/haptic feedback must make it have a poor contact and it disconnects.

I am curious, have you guys figured out this issue? I just got a new Nexus 6 that does this intermittently. The phone can read the card, but then every once ina while (about three times a day) it says 'no sim card - emergency calls only'.

I've noticed that banging mine against a hard surface (I do have a case on) seems to fix it for me, as horrible as it sounds... Mine does not fix itself after a reboot.
That said, it hasn't happened to me since I've had marshmallow on here.
In short. I have no idea what's going on.

I have had my replacement Nexus 6 for about 9 months and have not had this issue occur on the replacement unit. I'd highly suggest sending it in for replacement if you are still under warranty.

Push the SIM tray in really hard!
Push the SIM tray in as hard as you can!!!
I tried every other solution and this worked for me with Nexus 6.

I have same issue No SIM CARD with droid turbo, restart always solve issue, its common problem with Motorola phones, lot pf people are facing this but no solution yet

yeah my shamu after a new sim card did this, took it in, no fix, mytrendyphone service in england claimed they could fix it,, I paid they didnt fix it, kept it two months, sent it back unrepaired.
yes fairly ticked off. wifi only paperweight now.

OK first off I had the same issue. intermittent no sim detected. go worse and worse, until did not detect at all...
First I placed a piece of this card stock behind sim and jammed it into the slot. that worked for a bit and the again it started with the same issue.
and became a pain again...
(FYI, I am an electrician by trade)
What I has appeared to fixed it permanently (so far anyway).
All electrical contacts get a corrosion (a patina layer) some more than others from humidity, sweat, dissimilar metal touching, or just cheap metal..
On a hunch I gooped up the sim contact surface with a de-ox compound (De-oxidation) and worked the sim in and out a few time to "clean the contacts (you could use a small long skinny piece of paper board to to it also (I didn't think of it until after) and insert the Sim. So far it has done the trick.
the is many de-ox compound available (home depot or electrical supply)so are blacking and gritty. what I used was ilsco Non- grit De-ox Compound".
I hope this helps as this seem to be a pretty common issue.
As always, Your actual mileage may vary.

XZ3 WIFI and Network connection problem

Hi Guys, could you please help me out? A few weeks ago my XZ3 started to act weird. It working perfectly, and after a random time, suddenly its losing both the wifi and mobile network connection (bluetooth is OK). Sometimes a simple restart solves this, but other times its not helping. I tried factory reset, but the problem still occurs. Could it be somehow software related or it must be a harware issue? Any information could help a lot! Thank your very much in advance.

issue may be in chipset so repairing is hard.
I gave it to seller then he sent me another xz3 phone.
now I don't have such issue.
I think it is a manufacturing issue, few phones has this same issue in all Xperia models like xz2,xz3, xperia 1....

i got it fixed from a local repair shop. The issue is caused due to some loose components on the motherboard. There are a bunch golden pins around the edges of the main board, the repair guy called them "signal boosters". i don't know what they're actually called. They're all connected to two main signal boosters right in the middle of the motherboard.

UPDATE: it's the plastic middle frame of the phone!! i finally figured it out.

I'm sorry it wasn't the middle frame either. the issue came back after a couple of weeks, mostly when phone got hot under heavy use. i figured when i pushed hard on the side of the phone where sim card lies, the phone would lose signal for a sec or two and then come back to normal
I finally managed to fix my phone somehow it hasn't dropped signal even once in two months. i haven't been able to pinpoint what exact component is malfunctioning that's why I'm going to list every little thing i did..
it's definitely one of the metal contact points on the edges of the motherboard near the sim card tray that connect with the phones casing to boost the wifi and 4g signal. i put a small piece of medical tape on top of each contact point near the sim card tray to completely block them off. ( I've marked in the attaced pic exactly which contact points you have to block )
I've also removed the plastic dummy sim holder that sits just below sim card tray to fill the gap between metal sim holder and phones body. put a piece of paper medical tape there instead. put a small piece of paper in the top right corner of phone housing so that motherboard would stay a little above the housing when you screw it (see pic)
make sure motherboard screws aren't too tight
Don't worry it has little to no effect on phones signal reception, you're only blocking the sub antenna

So what you did at the end?
Any update on the matter?

I was able to partially solve my problem with my phone, I took out the black antenna frame and very carefully placed transparent scotch tape (because it´s thinner than medical tape) in all the contacts that are marked in red in the atached picture but now I´m thinking that I shouls have placed tape also on the places marked with green.
So what change I experienced on my phone with this method?
well the phone now has Network and wifi signal all the time and very ocassionaly it does lose the network and wifi signal for a second but when this happen the phone does not say that there is no sim card and does not freeze and restart, it just recovers signal by itself and I can continue using the phone.
