Getting Cell Service with NO SIM! And some other guys number ! Help

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
Dont thank/like/rep my posts or ill report you.

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.

[Q] Fresh CM10.1 won't recognize sim card

First of all, I'm a Sprint user, so the concept of sim cards is kind of foreign to me.
Just picked up an Atrix 2 for a friend, rooted, flashed CM10.1 from this post:
http://forum.xda-developers.com/showthread.php?t=2121029
Rebooted, everything's dandy. Turned it off, put in their sim card, and I still have no service. So I poked around, and under Settings -> More... -> Mobile Networks -> Network Operators, if I choose either Search networks or Choose automatically, I get an error. I don't have the sim card now, so I can't say, but one of them was "Error while searching for networks" I think and the other "Can't connect to this network right now"
I'm not sure how to tell if it's recognizing the sim card, or 2, if there's something I have to do to get service.
I'd rather not flash it back to factory if I can help it. I was hoping someone here could help. Thanks!

Did you ever try it on stock? if yes, did it work there?
Also, what carrier are you using, and if it is not whatever your phone was sold for (ATT if it has the symbol on the bottom, but not sure if you are in the US. If it is not the same carrier, it must be unlocked, but it should have asked for a code. Does it give you a message saying no sim card ever, or does it just not work at all?
I know that was a lot of questions, but there are a lot of things that it could be.
Also, try just blowing in the sim card slot and stuff to clear it of any lint or crap that could be in there.

Whoa. Brighton. I'm in Milford. Crazy. No, I didn't try it stock, but I just RSD'd it back to stock, so I'll try that next. I don't have the sim card with me. She had to put it back in her phone so she could have something. I'll try it in a bit.
Yeah, it's ATT. And when the sim card was in it, if I remember correctly, it just said "No Service". Before I flashed it to stock, it DID say "No SIM Card" So I guess it's seeing it to an extent. I'll try stock and report back.
Do I need to have the sim card in it once so it registers on ATTs system or something, then I can CM the thing? Like I said, I'm on Sprint, so sim cards are new to me. Thanks!

LOL, I'm Milford too sort of. Milford mailing, Brighton Township, but more people have heard of Brighton around here, so I use that.
Anyways, yeah that means it's seeing it and it is probably an apn problem. you NEED the sim card for any network stuff to work. let me know about stock, it could just bee that cm did something dumb, but my guess is you need the right apns for ATT, which I could give you. What phone is the sim from? it might not work with the A2 if it is not made for smartphones. once is stock, I would just bring it to the store if it doesn't work, and tell them to activate it, and they will give you a free sim.

The current phone is a Huawei something. Fusion? Fusion 2? I'm not sure. But it's Android, but it's 2.2 or 2.3. It's a pretty lame phone. I'll get back over there and grab the sim in a few hours, and see what it does.
So in theory, stock Atrix 2 rom, and her sim, it should just work, right?

It Should, but might not. if it does, keep the sim in and flash cm again if you want. if not, post a screenshot of settings--about phone--status
or just post the info of network through Mobile network state, and make sure the imei shows a number not some error.
also check under wireless & networks--Mobile Networks--Access Point Names and make sure stuff seems normal there. (should have ATT stuff of some kind)

That's fine. it is basically the serial number of sorts for the radio chip. it is distinct for all phones, and is how it is identified internationally for carriers and unlocking and such. sometimes with broken harware/firmware this can become unknown or something, so just wanted to make sure it wasn't a problem. I would say there is a chance you need to get it activated from att. you can't totally share a sim card, as they want ou to add the phone to the plan, but if the old one is going away, it would be worth just bringing it in and asking for a new card.

what is the background of the plan. like what did you have before this phone plan wise, and what are you trying to do now. my guess i things are not set up right, which could end up costing you more money if you have an old plan or something. let me know, and I can see if anything is glaring, but you probably have to have it activated or something, I remember calling to activate i or something, but I am not sure exactly what the process was.
the only info the will likely want is the last 4 digits of your SSN (or whoever's the account is under), the IMEI, and maybe something from the sim card.

[Q] Locked out of my phone.

Hi, I have an old LG Optimus T that has no service anymore, I got an HTC One from Sprint back in May, haven't touched it since. And basically, the phone has no service, and the lock screen was tried too many times or something back months ago, idk how, so I have to sign in with my google account, which I know, but without service on the phone, I guess it won't let me sign in, I figured my credentials would be saved into the phone so I could type it in without service, but Its not apparently. Anyway, I come here because I want phone numbers off the phone, I got all my pictures and crap because I can hook it up to the computer for that, and I don't wanna do a factory reset, because well, I don't care for the phone, I just want some phone numbers.
Thanks for any help ahead of time.

Hmmm, isn't it possible to connect to Wifi? Try going to an access point that you know your phone previously connected to. Also, perhaps you misstyped the SIM pin too many times? In that case, you have to enter a different code. Not sure what it's called in English, but you got it when you got your SIM. If you don't have that anymore, try contacting your carrier. Good luck!

I'm not sure, I just checked my google account in hopes that the numbers were all saved to that(like off my HTC One they are), but they weren't, leads me to believe that they are most probably saved to the SIM. Anyway to access these phone numbers vis USB and computer or something? Because I'm not gonna be able to unlock it...
P.S. lol @ this things battery life. I haven't touched the phone in like 1-2 months since last I tried to get the numbers off, and its still got half battery left. It hasn't been used, but still, that standby time.

Which is why you shouldn't purchase a non compatible phone, for use in another area?

This is why you shouldn't buy this phone from the scalpers. The chinese version does not support many of the worldwide bands that the "global" version of the phone does. My advice would be to try to sell it to someone who can use it and sign up on the OnePlus forums and wait for an invite for the CM version which supports the bands you need.

Get a new sim, sounds like an old sim that doesn't have the updated CellID info in it.
I had to change my 3 sim when I had my SGS4 as it wouldn't register because it was too old.

I had that happen to me on the interational one and felt quite dumb afterwards...
Make sure the SIM card tray is rotated DOWN so that the contacts on the sim card look to the back of the phone.
It will fit both ways (imho a very strange design choice) but with a tiny little space left when rotated the wrong way.
In other words: turn the phone on it's screen before inserting the sim card facing you.
I have _NO_ clue why the phone thinks it has a SIM card when obviously it cannot access it...

Phone wont register on network!! Need Help!!

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!

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.

Hi
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)

Just in case is some odd firmware problem , back up everything important first...just in case

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.

I have now found out that the phone is stolen!!! So that explains everything. I dont know why the carrier couldnt see that the first time they checked, would have saved me days of frustration!!
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!
Thanks for the help guys, very much appreciated even though it was an impossible case to crack!

Oh no. Have the police found out the thieves? I think my phone may be stolen too because I have the exact same problem.
