Hey guys,
So when tmobile dropped nougat for the s7 I restored stock/unrooted my phone completely and then upgraded to nougat. Since then though my phone at times will stop reading my sim card all together. now i have never had this problem until after i came from the g930u rom. Sometimes it'll read my sim, but sometimes itll just stop out of the blue. i could be doing almost anything. i went today to tmobile to make sure my simcard wasnt acting up. also my phone can read my SD card just fine . So im not sure if its a modem problem or what but can someone help plz, i dont want my phone to be a paperweight mp3 player? thank you.

I just bought a phone the guy who made no mention of the fact that it was rooted when I bought it. What is worse is he mentioned that his GF worked for Verizon, which did not seem to mean much at the time. Knowing that here is what i'm dealing with.
I was in a rush when I checked out the phone as I had to meet another person to pick one up for my wife as well. It's the sch-i575 in white 16gb. After having a minute to look at the phone it turns out he had Paranoid Android flashed and the phone was rooted. CRAP! Not what I was looking for and he was not upfront about it. The incredibly strange thing was that with NO SIMCARD the phone was getting 3g signal! I spent all night trying to unroot \ undo what he did. I managed to use ODIN to get back to the stock rom although I think it's still a rooted one since I still have the super user app. I got a sim card from verizon but since it was rooted I did not bring the phone in and when I tried to activate later it would not activate. My wife's by the way is working flawless and when I put my sim in her phone it works fine as well. I had to put the sim in my wife's phone and it activated there. Here is the crazy thing, with or with out a simcard the phone makes calls and has 3g internet only but when I make a call it uses HIS NUMBER!! I'm not sure what the hell to do, what could have he done? Any ideas? Please all help is appreciated! I did not think this was even possible for the phone to function w/o a sim. I'm worried about taking it in to Verizon because of the funkiness. Ty again for any insight...

It sounds like you didnt flash the proper stock image. I would start with that and report back.

I thought the I575 was an old slide phone. So A. your in the wrong section of the forum since this is Verizon's S3 or B. you mentioned the wrong device number? I saw phones before working and running on networks without sim-cards but that was years ago. If it is an S3, you sure it's a Verizon device? Also since you see 3g....can you browse around in the browser or make a phone call?

Yes, it's a galaxy s3 16gb in white. It looks like currently I was using the tar66 using ODIN. I'm reverting back to the bone stock one now. As far as the models go isn't the SCH-I575 the Verizon version of the S3?
I'm waiting on the stock unrooted rom to take through ODIN and will report back. Thank you for taking the time to try and help.
Ohh, yes the internet works and when I make phone calls with or with out my sim in it makes calls successfully but the other guys number shows up. What the heck did this guy do to the phone!
Our model is the SCH-i535

You are obviously absolutley correct. I'm frantically trying to figure this out. I have flashed the stock rom and don't have super user anymore. The problem persists with the guys number.
Could he have flashed a custom kernel and modem or does reverting back using the stock rom cover all that ?

The one i linked covers all that and completely erases all data on the phone. Did you insert your sim after the stock flash?

I just double checked and I had the I535VRLAG1 version, yours is the I535VRALF2 in the link you posted trying this now. The crazy thing is that it even says that the sim is activated with MY number! but the calls are still comming from him. I even tried wiping the device and clearing the cache. I also tried to JUST flash the modem with VRLG1.modem.tar.md5 and nothing :\. Waiting on the file from your link to download and will try that.
Is it possible that this is being caused by something on Verizon's end? The phone ( with out the SIM ) is registered to him somehow? I know this is not normal but because his GF worked for Verizon could they have done something funky?
Yeah its definitely possible its from something she did to the phone but most likely nothing from Verizon's end. Does the IMEI number under status match the IMEI number under the battery?

Yes IMEI is the same in the OS as behind the battery.
The curious thing is that on the same screen in the OS where you find the IMEI there is also a field called Network and it says " Unknown"
It also has things like:
Eri v : 5
Mobile network type : EvDo-rev.a:8
The thing I keep coming back to is how is it possible for this phone to make calls\ have data with out a sim?
Starting to really think I got cheated
Cheated? Sounds like you have free Verizon service.
Roll with it. If you really want a bill you can have mine...

Just did and the same thing happened. I went to the Verizon store and the guy there had no idea and got me in touch with tech support from the store. They were dumbfounded and flat out said that what is happening is impossible. "It's impossible to make\receive phone calls with out a sim unless they are emergency" I harped on the fact that I am making phone calls as one of their other customers and that this is a big deal. In the end since I had the insurance and extended warranty they will ship me a new phone.

Hello guys!
I love this phone, but i am having problems getting it to function properly here in Sweden. It was originally bought on a contract and simlocked to Tre (carrier). I bought the phone second hand from swedish ebay (much cheaper than brand new) with the intention of unlocking it and using with my carrier (Telenor).
Tre would not unlock the phone for me (have to see out 24 month contract) so i unlocked it myself using the services of unlockscope.com. The process was successful, and the phone no longer asks for a network unlock code when using previously locked sim.
The problems start now.. It just refuses to register on the network! If i switch the phone off, insert sim and start, then i get a brief flash of the carrier name in top left corner (2 seconds), and then it goes back to saying emergency calls only.
I cannot register manually, i have tried hundreds of times, even though the carrier appears in the list. The apn settings are also correct for my carrier.
I have also contacted my carrier and they dont understand the problem. I even had them run a check on the imei to see if it was blocked on their network (possible stolen phone) but it came back negative, no blocking whatsoever!
The weirdest thing is that it works when using my brothers Tele2 sim card! The phone registers in seconds and displays a nice 4g symbol next to the signal indicator! A thing to note is that this Tele2 nano sim fits very nicely in the tray and stays in place, whereas my telenor sim is extremely loose and falls out, though i have tried taping my sim in place with no success.
Can anybody relate to this problem or think of a possible cause? I dont know what to try anymore! I'm thinking that there must be something wrong with the phone, but then why does Tele2 work perfectly??!!
Sorry for the long post! I appreciate any help offered!

This is getting weird , did you try to do a factory reset from recovery also wipe cache and if that do not work you could also try to flash the firmware of the phone again ( odin)

I have already tried flashing with stock swedish firmware using odin (G930FXXU1APEQ_G930FVDS1APF1_VDS) but same problem persists.. One weird thing to note though is that even though i do a clean flash with unbranded swedish rom, the phone installs some carrier specific apps from the original carrier the phone was simlocked to upon first boot. How can that be??
Maybe its worth trying an international version?
Thanks for the suggestions

That is odd , yes try a totally different rom just to see how it turns out , even from another country it should not make any difference for the phone and connect easily to a network.

EFS is a very important partition , is where the modem information is.......maybe?

I will try with an international firmware and see if there is any difference.. if not i will follow that guide on efs partition in case that is corrupt.. This is so frustrating!!!
Is it at all possible that a very loose fitting sim could be the problem? As the simcard of the carrier that works fits very snugly in the sim tray.

It has been reported to the police here in sweden, so hopefully they will find who is responsible and i can get my money back!

Oh no. Have the police found out the thieves? I think my phone may be stolen too because I have the exact same problem.
Hey guys,
So when tmobile dropped nougat for the s7 I restored stock/unrooted my phone completely and then upgraded to nougat. Since then though my phone at times will stop reading my sim card all together. now i have never had this problem until after i came from the g930u rom. Sometimes it'll read my sim, but sometimes itll just stop out of the blue. i could be doing almost anything. not sure if its a modem problem or what but can someone help plz? thank you.
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
Hi all, new noob member here with hopefully a simple question. I bought an unlocked S20 with tmobile firmware about a month ago. I'm using a verizon SIM card and everything worked fine until yesterday when Tmobile sent out an update. At first I had no mobile data but could still send texts. After searching, i saw under my SIM card status it said IMS not registered. Not knowing much about this stuff I was thinking that maybe I needed to flash verizon firmware onto my phone and that would fix it ( I have not done that yet). I went to the verizon store and got a new sim... same issue. I also found a website listing access point details, I plugged in all the information and now I have 4G but i am still unable to send texts. I'm wondering if anyone has any ideas as to what my problem might be. I'm trying to avoid flashing new firmware onto my phone because I don't have a great understanding of how to do it, and i really dont want to brick my phone. Any suggestions would be appreciated.
