No SIM????

Okay, so I got my Galaxy Nexus today... went to put my SIM card in, and it refuses to acknowledge it. I thought maybe it was due to a very old SIM card, so I went in to T-Mobile, explained my situation, and they replaced it with a new SIM card free of charge. Problem is... the Nexus still REFUSES to read it. It keeps saying 'No SIM/Emergency Calls Only'. Help please?

Is the phone new or used? And do you have warranty? It could be because of the phone

It's used. It came pre-rooted with AOKP on it... I was thinking this might be the problem? So, I'm in the middle DLing the GNexRootToolkit to return it to complete stock, and see if that helps. Any other thoughts?

are all the pins there? If any of the pins in the SIM slot are bent or broken, it won't read the SIM.
I also find it hilarious that people buy used phones without knowing for sure the SIM slot works (one reason to only buy locally for used devices). I personally will never buy a used phone that is also rooted/unlocked/ROM'd. I don't wanna get some hand-down phone that's been messed with. If they can't be bothered to return it to stock, I won't buy it.

Okay, that seemed to fix it. Thank you for the quick replies!

Can't believe you bought a phone without checking if it worked. Smh. Well, glad it worked out for you.

HELP SIM tray broken

Well, my SIM tray holder is broken, I can see a small spring and my SIM doesn't stay in. I have tried to get the same part for the S3 t-mobile but can't find it.
I found the international one, SD SIM tray holder for i9300, but wherever I go, the only say to be compatible with the i9300. Does anybody know if I can use this part on my t-mobile s3 ?, the parts look the same (at least to me).
Thanks for you help

If I am correct you still have a year warranty thru manufaturer and TMO will replace device. My daughter had a BB Curve and about 9 months in starting having rebooting problems and they went ahead and replaced it 3 times and on the 4th gave a crazy discount towards another phone. More than likely it will be refurbished unit not a new one. Refurb has got to be better than buying a part that you would have to install yourself and possibly mess something else up. We did not have insurance on that phone either. So if you bought thru TMO call them up.

As long as you're the first owner/first to register service with T-Mobile with that phone, you can claim the warranty.

Nano sim adapter

In case anyone wants to know, my nano sim adapter is working fine since putting it into my Note 2. I haven't tried taking it back out yet n back into my iPhone but so far so good.

Be careful with those adapters, there well known to get stuck/ or mess up sim reader. I almost messed up my note 2. I was using a nano sim adapter with my note 2, was taking it out to put in a t-mobile sim so I can unlock my phone. When I ejected the sim, I tried pulling it out and it got stuck. I panicked for a moment, I was like I'm about screwed, I'm about to have a $700 brick. Intstead of trying to pry it out, I got one of my girlfriend's hairpins and started slowly slide it out. When I was almost done, the adapter got caught again by the gold prongs of the sim reader. I just had to pull it out with force. I switched back to micro sim, the sim slot in my note 2 is fine, only issue now is when I pop the sim out, it doesn't come out all the way anymore, i have to wedge the sim out. But no issues putting sim in.

Good point, I haven't tried taking it out yet but the thought that it may get stuck has crossed my mind. I'll be careful when I do try n remove it

i am curious anyone have any experience with a particular brand that does not get stuck with a nano sim adapter? thanks

Same issue recently, but my outcome wasn't as good. Ripped out one of the sim pins and that killed my phone. Luckily ATT warrantied it. Not using adapters anymore in this phone.... this also helps me curb my phone addiction... micro-sim phone's only

Almost all adapters do that as they are not well deigned and I tried many of them for many phones over the last 2 years and I did break of the connectors also on a Samsung focus when I had one. However I purchased Noosy adapters from amazon and they are the best I have ever seen and have taken my Noosy adapter with sim in it many times from galaxy s3 to iphone 5 to note 2 with zero issues. I highly recommend Noosy and no I do not work for them but I do switch phones around and go back and forth.

I don't recall what kind of adapter it is since I bought it during the summer time. I had to use alot of force to remove the adapter and now the phone doesn't read the sim card

That happened to me with a Samsung focus. Sounds like your sim connectors broke off.

Oh no
Same just happened to me.
Nano adaptor jammed, had to use force and Note 2 is no longer a phone.
Not in warranty either. I can't believe it's happened.

same goes for me lucky for me samsung is sending me a new one
i was using the noosy sim adapter and yea it got stuck got it out was working fine for a while then it finally just gave out and said no sim card or sim card error sent it to samsung waiting for it to come back they just shipped it out today ><

Noosy makes the only decent sim adapters I have seen.. they are easy to find on Amazon or eBay

oh man, I didn't even think about that happening. I am using a adapter right now. Should I try not to ever take it out than? If i do need to take it out and tips?

Adapter killed an Atrix 2 I had... it went in just fine but when I took it out it broke 2 of the gold pins... would've cost me about $150 to get it fixed and I couldn't even find the parts on the internet so I could try to fix it myself... trashed it
If you try to take the adapter out take it REALLY slow and absolutely don't force it... those little gold pins are really fragile.

SIM card not detected - then detected again

My phone is constantly failing to detect the sim card, usually if I restart the phone or leave it for enough hours it will "find" it again.
Short of reflashing it I'm not sure if there's any way to determine if this is a software or hardware issue. The phone itself is a refurbished one (thanks to the phones insurance replacing it a few months ago), however it is now out of warranty. If it was a hardware fault, how much would it probably cost?
Thanks, Shaun.

The first thing I'd try is a different SIM card or a different SIM card insert (bit of plastic that the SIM sits in).
Has this always happened since you've had the phone?
or
Has it happened since you flashed the phone?
As for the price of repair I haven't a clue (i do all repairs myself), but my guess is in excess of £150
You may want to provide more information before other, more experienced people, come to your aid.

It's slowly gotten worse over the last few months (the first couple of times I just thought it was a once off bug or something, which is why it's very difficult for me to give you an exact when it happened).
The fact that its gotten worse in itself is leading me to guess its a hardware fault - I could have knocked or dropped it and not remember or something.
I don't have any other SIMs but I'll give flashing it to a different ROM or stock a shot first.

Does the phone say no sim card (with icon) or do you lose service?

It has done both, the latter's slightly more common though. Probably more often than both it will momentarily drop out, then come up with a "Preparing SIM card..." message.
Still happening after flashing it with a different ROM. Looks like it's probably hardware :/

Might be coxicial cable that connects the pcb with antenea board they do come off from time to time

Hi there,
i have a similar problem with my device:
network disconnects sometimes (for some reasons ok, as example when i sit in the underground or other places without gsm network) - but then the services doesnt comes back - i'm complete offline. next behavior: i'm just talking with full gsm bandwidth, and for really no reason i get disconnected -> no network anymore, no service anymore.
can it be a hardware fault or should i try to flash the modem (when possible) ? I'm on the latest HTC firmware, device isnt rooted or flashed... it is as i got it from the market.
thanks for a hint what i can try

See above could be that, what network you on?

I'm on GSM (in Germany the O2 network)

maybe the network fault can be solved:
just have read in the vodafone forum in uk and found a hint from a user, who was taping the back side of the SIM card with 2 stripes of plastic.
Have tried this and report tomorrow here if it solves the issue

Tested with taped SIM card and i can say: it works like a charme

Tmobile Note 2 no network circle crossed out

Hi and thanks for any help that you can provide me.
I bought an Galaxy Note 2 SGH-T889 Tmobile version like 7 months ago from a store or reseller in Toronto Canada, the phone was in theory factory unlock, to use with the Wnmobile network which uses the same frequency as Tmobile. The phone was working until 2 days ago. Well always the phone has issue connecting to the network in some specific areas, specially because the Wind network it's not that good, but during the last 2 weeks I noticed more and more problems and some times it was just disconnected showing a circle with an slash or crossed out. After reboot the phone usually fixed the problem, until 2 days ago I had to do it every 2 hours and then the next day it just was permanent. I tried everything so far:
Remove battery and reboot
Remove battery and SIM card and reboot
Use a diiferent SIM card from my son's phone
Replace for a new SIM card
Clear Cache
Factory Reset
Reflash the modem with Odin
The phone has the latest stock ROM 4.1.2, BASE T889UVBMD1
The problem is Samsung say because it's a Tmobile they can not support it here, I have to send the phone to Samsung USA, I still fighting with the store because they said it will be covered locally, but that is another story.
I red many post talking about similar problems with the Galaxy S3 or S4 and one said that installing Jedi X14 fixed the problem, but to do that I think I have to root the phone, which not be a big problem.
The other weird thing is the phone works using other SIM card GSM, not tested with a LTE SIM.
There is any way to test if the radio/antenna for the WCMDA is disabled or broken
Thanks

If the phone is working fine with a friends sim card . There is nothing more then a issue with your sim. go to the store and have them to give you a new sim card or flash the one you have. I had that issue similar here with at&t all the time.. sims would just loose network.. The fix for me LEAVE AT&T
Good luck.

Yes, I replaced the SIM card and I got a new one.
Just trying to eliminate all the options, I just did a factory reset again, and put it back the SIM card, located outside in an area where I know there is a strong signal and the phone was able to connect to the network and I install the account ans the apps just to test the data connection and it works fine. I was outside for 20 minutes with no problem. Later go back in the building, as soon I was inside for a few minutes the phone lose connection and the circle is back, then reboot again several times, and the phone does not recognize any network, Searching and no network is available.

Aww you left out that it only does this inside but works outside.. I Would say something is blocking the signal. LIKE maybe the building..
i have two bars in my house 3 on the deck and full signal in my yard ...
its just how it is..

But he said it was working in side for many month then all a sudden it doesn't work? I understand I live in a mobile home and reception sucks but that from the start but his was working for couple months. I would say he's phone reception receiver w/e it is or something in the phone is screwing up and it will need repairment or replace or service just taking a dump and getting worse.

You could be right.. or maybe even the provider having issues with that tower .. its a tough thing to figure out..

Thanks for your ideas.
I get tired of trying to figure out was is the problem, so I got a SIM card from a diiferent provider which has the best network coverage and power, and i'ts happending the same, the majority of th etime the strength level is around -110 db even outside, with both providers, so it's the phone.
Now the question is could be possible that the antenna cable got disconnected or broken, (yes I dropped the phone a few times but nothing major) and it was working fine until few days ago. Another option it's some internal hardware is not working normally.
Now I have to find a way to repair becasue Samsung Canada does not want to do it becasue its a Tmobile phone.
Thanks, again.

Anybody with same provider as you? Invite them in you're home see if they have connection. It's best if the person have same phone and same company. Can you send directly to Samsung? I have bad phone service my area with s2 and note 2 but my friend with evo 3d has more bar then me and its made by htc but could be two things ur phone crapping out on you which need repairment or like the guy above said tower signal getting weaker. It is hard to find out. Maybe for now for a bit since it's screw up try a rom but then again rom doesn't control radio settings section but wouldn't harm. Good luck.

I'm having the same issue since last month... but with any SIM card.
The network signal strengh rests between -89 to -110 dBm. (Horrible)
The network type is always UNKNOWN:0.
What I already tried:
- Using other SIM.
- Flashing Stock ROM
- Flashing Custom ROM (CM 10.1)
- Flashing all 5 avaliable modems.
What happens:
When I get VERY close to a network antenna... I can make calls and stuff...
What can be happening:
Hardware issues - T-Mobile latest LTE unlocking update maybe burned my antenna (or some network signal related hardware).
Software issues - Can't see how since I used many variations of ROM/Modem.
I live in Brazil and my network is TIM 47. I have a Samsung Galaxy Note II T889.
If anyone can confirm perfectly to me what composes the T889 antenna components... that would be nice...
I want to buy those parts from eBay and trying fixing my phone.

Thanks for your feedback it's really valuable becasue it's almost the same situation. Today I cleared up the situation with Samsung, if I want to be service under the warranty I have to bring the phone to one of repair centres in USA which it's kind of problem because I can do it only in the weekends but not impossible or what I'm doing tomorrow is to have an assessment by one of the repair centres in Toronto and I have to pay in this case, if it's something reasonable.
In my case I did not update the phone in 2 months at least so it's not software in my case, but one difference could be I got a new job 3 months ago, in my previous job the majority of the time I got 5 bars , I guess the cell tower was close to that place, and in my house the coverage it's good. In my new job, my office it's in the middle of the building, far from the windows, so the signal always was really bad, 0-1 bar.
Wondering if could be possible that a bad connection can burn the antenna or the circuit that controls the connection.
The other thing is there are many customers specially for the Galay S4 complaining about a similar problem, and I did not find any answer on how to fix this problem.
I'll post any update just in case it can help someone else.
Thanks.

A also have this problem with T-Mobile Note 2 and have already tried everything you guys have...I guess I got no choice but to request a replacement which sucks because my phone was pristine and worked perfectly otherwise. It's just the damn weak to no signal that's driving me crazy. Especially since I'm paying for premium data coverage and it's pretty much money in the trash every month.

That's it. I made the call and the replacement arrives in a couple days. They offered me the "jump" program. Anyone on that? Is that worth doing on T-Mobile?

I traded an unlocked i317m for a g pro. I just picked up a unlocked t889 as welll. The person with my old i317m want my t889 since hes using simple mobile. Problem is when I went to trade I put his sim in my t899 it wont register on tmobile. Seems its only working with at&t as thats the service I have. Now with the i317m I gave him originally it works with any sim. How is this possible that a unlocked tmobile t889 wont register with his sim on tmobile network but the unlocked i317m works with any sim?

Yesterday I replaced the microUSB module that is connected with the antenna and replaced the SIM card module too.
That did NOT worked.
So... the problems is problably on the mainboard/chipset... too expensive to fix.
Another big hardware failure for Samsung's history.

I've had the replacement for about a week now. So far no signal problems. It's like when I first got my original phone. I'm sticking with the note 2 for at least another 6 months since I joined the jump program. Can't wait to see the note 3 next week

Update just to close this case
Well, after I sent the phone for repair to Samsung USA, I got it back and the problems happened again after a few days, then I sent it back for the second time to Samsung, got it back and the problem happened again after a few weeks. Basically, I'm getting rid of this phone, now the warranty is already expired and half of the time the phone was full of problems with the network.
The lesson in this case is to avoid getting hardware from the first batch (to wait a few months after the launch) or without a long term warranty (3 years), and probably will be my last Samsung device.
