SIM card not found

I dropped my phone recently, and almost everything fell apart. When I picked it up and put everything back in its place, it wouldn't turn on or boot past the IPL/SPL... screen. When I finally got it to boot, the SIM card was recognized, not now it's kinda spotty on when it wants to recognize it, even when it's in like now, yet it tells me its missing. Can anyone help me with this?

Probably the best thing to try would be to go to a local t-mobile dealer and tell them that you need a new sim card and see if that fixes it. They used to just give them to you free, but the other day I went in for an upgrade and when I asked them if I could keep the sim that came with the phone since I still wanted to use the old one for now they told me that it would cost me $20 so I'm not sure if you'll be charged for it or not. T-Mobile did get a nice nasty e-mail from me about that one.

Hmm I'll try that, talked with mfrazzz earlier and he thinks it could have been that I knocked something loose.

That's quite definitely a possibility, but I figured trying a new sim card first (if you can talk them out of a new one for free) would be the easiest thing to try first.

[Q] No GSM signal after repair??

Hi to everyone
I bricked my phone after flash. It was compleatly dead.
The problem arrives when I collect the phone from repair shop.
They did not charge me coz the phone don't see any network. I thing they resurrect my phone and flash it from basis.
Phone was unlocked by code before I bricked it.
Now everything is working fine but after inserting a sim card it saying "no network"
Any ideas or sugestion??
Thanks

When you send something for a repair and get a non-working thing back, do NOT mess with anything and send it back where it came from. They were supposed to repair it, huh?

Thanks for a quick reply
The phone was compleatly dead after my flashing, it was not reacting at all. I was flashing with unofficial firmware so I'd think that sending it to LG it's not good idea.
So I give it to repair shop. After a week the phone was ready but with no GSM. They said "it's only this what we can do about it".
Second repair shop tried to flash it with official T mobile firmware. The same- no gsm.
So I'm left on my own.

Well, phone without GSM is useless.
How did you brick it exactly? What were you flashing and how?
What is the ROM installed there now? What is the baseband version? Is there any IMEI shown in phone info?

Yep, but is good for wi-fi
I was flashing with LG official software and it fails. I forgot to enable LG virtual modem driver. The software utility hangs up for 4h. I woke up pissed off and i took battery out, I know, I'm genius. After that I lost ability to enter emergency mode, even fast boot was not working. Oh my Lg R.I.P
I was updating from 2.2.2 (KDZ flash) to 2.3.3 (LG update tool)
IMEI is showing
Baseband AMSS6038
Rom LG-P500-V20e (2.3.3.)

One more thing
When I collect phone from repair shop the IMEI was 0 and they change it to normal, like on the label.

Should work... The SIM is good? (Try another one ) Is there some GSM signal around?
Other than that, you can try to flash again via LGMPD or whatever. If it does not work, then brick it again (you have the know-how apparently ) and take it to LG for PCB replacement.

Send it to lg service centre..they have more knowledge and experience den repair shops

I'd try 3, vodafone, orange and O2 sim card
Signal coverage in my area is good
I was also flashing throught LGMPD
When phone was in repair they opend it. There are marks on screws and on the top from prying tool. You think I should try send it to lg??

Well... if you want to use your phone as a phone, then... Ask them whether they would charge you and how much.

OMG... is that the job of the "repair" shop?! In that case...

I know. They should sell potatos on the market, not fixing the phones.
Oh well. I'll call later to lg and ask about that or brick it again, cover marks on the screws and hope it'll go throught.
Thanks a lot for help

One more thing - does the current IMEI match the one on the box you got with your phone?? Cause what I suspect that they took some ****ty broken board from a phone with non-working GSM and did put that into your phone. Kinda doubt the morons who are using prying tools would know what JTAG is and how to work with that.

@Omen-am: I have the same problem, used the same flash methods and also got my phone bricked. Go someone on ebay to jtag resurrect it and now I can switch it on, have already flashed all the versions of firmware that used to be on there to the latest GB but none of them recognize my sim card (which work fine in my old phone). So now I have a perfectly working "mini-tablet" working fine with wifi, bit no gsm service. So my question is, have you been able to fix yours? Do anyone out there know of a fix?
Thanks

Hello, I purchased a galaxy tab 7 plus in Hong Kong. All work great until 2 days ago,

Hello, I purchased a galaxy tab 7 plus in Hong Kong. All work great until 2 days ago, I inserted another Sim card then it now says no Sim card. I tried with several other Sim cards but no luck, I did a factory reset, flashed with firmware from Sam mobile but still no luck, I don't know what else to do before I send it to Samsung for repair that gonna be expensive, help is greatly wanted, thank you.

Try to insert the sim card with the tablet on. Does it restart? If not are you sure you are inserting it with the correct side?

Hello, thanks for the answer, I tried all that already, anyway the Sim only fit in one position so you cannot take wrong.
The tab restarts when inserting card yes.
I tried also taking the battery out for 10 mins... Clean the head of the Sim compartment but no luck.

Just removed the back by pushing under the sd card slot then inserted a flat tool to unclip the lid, then removed the batery connector.
However i still have the issue, its driving me crazy as it is my working tool...

does the original SIM still work in it?
perhaps try flashing original & latest frimware updates for new/different modem.
I know one chinese version of tab plus has locked bootloaded dud to China's restrictions, I would not be surprised if they have locked down modem as well.
And for the heck of it you could always try Galaxy S Unlock app, to be certain you're unlocked.
Strongly suggest backing up /EFS folder (twice) just in case.

Thanks for the suggestion, I flashed the device twice already but there is only one file. Could you direct me to the files you are referring to please I'll take a look when I'm back home, thanks again.

I would try EVERYTHING else before flashing a new modem. Toggle airplane mode. disable/enable packet data, etc.
First, does the original SIM still work?
If so I would give the Galaxy S Unlock a shot for the heck of it.
These other SIMs have you tried them in other devices to either make sure they work or activate them?
did you purchase device on a SIM contract??

sim issue
The original sim does work, i have put it in other phones and it works fine, i have also tried other sim but still same issue, message still say "please insert sim card"
I have purchased the tab sim free in hk so no, no contract, it did work fine since december until 2 days ago where i input a data only sim card, when i insert sim card it does reboot, meaning it detects the card in the socket but thats it.
Concerning Galaxy S Unlock my tab is not rooted i have used only legit firmware until now so im not sure about that.
PS: looking at my phone servie status it says:
Service State: Out of service

Are you sure you havent been sold a bad or expired sim card?
Id try to give samsung customer support a call at least, they will probably tell you to send it to them anyway.
Can you try exchanging this for another one where you puchased it?

Well, i bought it during my holidays in hk but i live in norway, so... bit difficult to chage it, the sim card works just fine in other devices so it should work in tab.
I tried the galaxy s unlock and during step 1 it says error for efs backup, so either because im not rooted or because my efs is corrupted.

Probably because youre not rooted.
Im wondering if the SIM could be from a small provider which isnt recognized by the device?
It should at least dected then say something like network provider unrecognized, etc.
I really dont what to say.
I would keep trying other sims, try to get a 5$ pre pay from a major carrier like O2, 3, tmobile, etc. not sure what carriers you have over there.

Well i use Telenor which is the biggest and also quite big in europe, i will call customer service tomorrow and hear what they say, but i fear its gonna rip my pockets...

did you push the simcard all the way to the bottom of the slot?
I need a pen to push it....so I wonder if you insert your sim card properly.

yes, since the first time, repair shop said they cannot help since device has been purchased in hong kong...
No solutions until today...

Solved
After dismantling the tab completely (hard work guys...) i confirm that the sim card reader is defect, the cushions that reads the card did not press completely on it so i applied a temporary fix by adding an extra layer to thicken the card so it can press correctly on the cushions. I did try this fix before with the tablet in one piece, however i could not get it to work correctly.
Anyway thanks for your help and i'm happy that i can use it again

[Q] Problem during call

I have this phone from 2 weeks. It works fine but i have a desesperating problemi with call
this is my signal gsm screenshot during a call
you can find the image attached
Data were disabled during this call. I was in movement but in a Street that i know and where every my old phone work perfectly with my provider (Wind - Italy)
Every time that the line went to 3%, I lost the call. It happens every 5-10minutes. I had original rom, now i Have CYanomod 11 but nothing changed... can someone help me? Maybe I have a phone with hardware problem?
The same diagram without call looks fine and no lost signal in the same zone.
thanks you!

Sounds like a bad SIM card mod...
If @CornholioGSM did it, I'm sure he'll be able to help you out. Even if he didn't, I'm sure he'll help out... but the fee may be different

I bought the phone modded directly in Italy in EBay, but if someone can help me, I will be very happy! Fee isn't important

SIM card not allowed after coming back from Japan

Hello guys,
Im coming at you for a question which I can't have any answer.
I bought a Note10 Plus in October to somebody on the web, the phone was brand new (on its original sealing and packaging) and working perfectly. I was first on Three network, the phone worked, then I switch on GoMo, working perfectly too. On the 10th of November I traveled to Japan with a local sim card (Docomo) and same, all working. But yesterday, I came back to Ireland where I live, and still as of today, the phone show me 'SIM 2 not allowed'.
The phone is unlocked, I've checked with the Samsung support and they confirmed it (but didn't bring me helpful troubleshooting steps). I've contacted my carrier too who said that there is no issue on my account, and they will send me a new sim card too.
I'm not expecting it to work though, as the SIM card is working on the iPhone X of my gf, and her sim card is not working on my phone too. So it's only on my Note 10+.
I've tried to remove the sim and reinsert it, restart it, reset network settings, check the date and time, nothing to do, all go to the same error.
After making research, I tried to check some IMEI Blacklist check websites, but I don't trust them as I don't know where these infos comes from, but one catch my attention because it told me that the phone was blacklisted : https://www.imeipro.info/
All the others says that the phone is clean. Again, that's why I don't really trust it, and my carrier didn't mention any block. I'm still curious why my phone appear as blacklisted so I send them an email to try to know more.
I receive signal too, but can't send/receive calls or text, and I don't have access to data neither.
So now I have my phone with no any SIM working, and I don;t know what to try to get my phone working again.
I think I've explained all I did today, I don't know what to do more, I don't have any idea of what's going on with the phone, that's why I need your light to see if you can help me to find a way.
Thank you guys, I hope to hear from you soon!

From the sounds of it, it sounds like it's been blacklisted, that's my guess. Do you get any message when you insert the sim? I had a similar thing happen to me, turned out the guy I bought the phone off on Ebay didn't pay he's bill and phone wouldn't text or make calls anymore. O2 was the company that barred the phone, and they couldn't help me even though I had proof I'd purchased the phone from the guy, only he could sort it out as it was he's account. Anyway thankfully PayPal came to my rescue, they just needed proof it was blacklisted, carphonewarehouse did a check and printed out the results for me thankfully as I knew the guy that worked there. I got a refund and promised myself I'd never buy a phone off Ebay from a personal seller, if its a business account then maybe. Awful experience though. I hope you get this sorted.
I'm guessing you've never rooted the phone or flashed it as that can sometimes delete the efs folder which causes the phone to have no imei.

Thanks for your answer !
No usually I root all my phones but this time I wanted to keep it as normal, because tthe phone looks like there's nothing more to improve to me (except a little bbit the camera when the light is low..)
I didn't knew that it could cause such things ! I should have done that
Honestly that was the first time I bought the phone to somebody, and more of that, the phone was sealed on the original plastic with the label ''eu sim card only''. So I was trusting it, even if I know, that doesn't mean it's safe behind that.
Since I've posted the message, I contacted few carriers, like mine GoMo, and they dont know anything about the blacklisting (I was surprised) then I contacted Three, they told me that the device does not belomg to the; so they can't check.
I tried Eir, and they refused to give me infos for data protections, which I think is stupid because the phone is not a personal information who could reveal an identity but anyway. I didn't though about Carephonewarehouse, I will visit them because it seems like this is the best idea.
The weird thing to me is still that it didnt worked suddenly... I was in the flight and this is when I came back that it didn't worked. Well, maybe that was a bad hazard.
Something I've discovered yesterday more of that is when I have this issue, turning off the 4G and only allowing 3G/2G will allow me to use the data. Still no phone or text, but the phone is detecting the H+ signal and I'm free to go on the web.
Yes for your question, the issue happened instantly when I insert the card on the SIM1 with the error SIM not allowed, the SIM 2 slot works perfectly, that's what I'm using for the moment but I can't use any SD card at the same time, so it bother me. :/
Thanks for sharing your experience, then I know a little bit fore of what to do. I wanted to go to the police but I don't want to spend 2 hours there. Maybe I'll think of it as a last resort...

I just came from Japan as well I had the same problem but with my Sony Xperia 1.
I bought it from the states and I took vacation to Japan and used their sim card.
When I came back here in Florida I switched back to my at&t sim card I couldn't make calls or texts only data works for some reason I tried everything I used sim card on other phones (sim card is fine)
I tried everything, nothing worked !
I factory reset the phone and it worked, fixed the problem (it's strange because I used Galaxy s8 also with that sim card and it's working fine)
My Sony Xperia 1 had similar problem to yours
I don't know if this will help you to be honest but I had kinda same problem.
Hope you solved you issue.

Thank you for that, I've tried this yesterday after a backup, I used the sim card with the phone completly as new (well, I've restored it from the settings, so I don't know if it was the good way) and it didn't worked.
I think I will try carephone warehouse as jadaress1 requested, it might give me lot of infos there. Im also starting thinking that the phone is carrier blocked, but I can't see any reason why the phone was new and already unlocked so I don't see any reasons...
I'll let you know
