Hey all, I’m having problems with my sim card not working, my Captivate doesn’t recognize it at all. I got this captivate to hold on to from my older brother who is currently serving overseas (not possible for him to use phone) a few months ago. When I got it, I rooted it, sim unlocked it (I have t-mobile), and got to flash roms and have fun with it thanks to you good folks on these forums.
About 2 weeks ago, the speaker was issues that really bothered me(had to keep tapping it in to get It to work) so I decided to send it over to Samsung to fix. The phone was still under warranty, so it cost nothing to fix fortunately. I just got it back yesterday, and since then my t-mobile sim card would not work. I rooted, sim unlocked, and flashed many different roms and still not working. Its as if the phone thinks there is no sim card at all (“No SIM Card Emergency Calls Only”). I also tried this app called Samservmode, and enabled all bands (GSM/WCDMA) to see if it would work; it didn’t.
I was ready to call Samsung again, but when I went over to my friend’s house and tried his att sim card; it worked perfectly and I was able to send texts and make calls. So something must be wrong with my sim card, it works perfectly on my g1 though (my backup phone that was used while Captivate was away). I was able to use the same t-mobile sim for a few months in a row before I sent it to Samsung, isn’t this possible for me to do it again? Any advice on doing so would be much appreciated; thanks.
P.S. My t-mobile sim card is prepaid if that matters, so I don’t use 3g or edge or any data networks.
Also my current setup (if it even helps, I've been flashing between froyo and ginger nonstop trying to fix this issue)
Firmware: 2.2
Baseband: I897UCKB1
Kernel: 2.6.32.9
Phone number and network is unknown
Mobile network type: HSDPA
Service state: Out of service
Roaming: Not roaming
Mobile network state: Disconnected
Everything else works pretty fine on this phone (wifi, bluetooth, etc.)
UPDATE: I went back to my friend's place and with his att sim card in, I tried adding a t-mobile APN based on
http://forum.xda-developers.com/showthread.php?t=744535
Unfortunately this did not resolve the issue. I did this with his att sim card because when there is no sim (or in my case, my tmobile sim) in the phone, you can't access mobile networks in settings.
I am also currently on stock I897UCKH3
UPDATE 2: So I just tried my other friends t-mobile sim card (that is on a plan) and the captivate had service; was able to make calls and text. My prepaid sim card seems to be the culprit here. I don't understand because as I tested my friends sim card on the captivate, I also put my sim card in his iphone 3gs (unlocked) and it worked fine there. Is the captivate on strike against my sim card or something? I'm going to try calling t-mobile tomorrow (doubt they'll help since the captivate isn't their phone) and see if anything can be done. In the meantime if you guys have any advice, I'm all ears.
UPDATE 3 (This is getting kind of annoying): I just got off the phone with both Samsung and T-mobile and both of them don't know what to think. I'm beginning to think this is a special case and this problem only occurred to a very few amount of people. If anyone can help with suggestions I would be very grateful. I'm thinking about going to a t-mobile store today to see what they think, maybe seeing the issue in person would help in their perspective.
Doubt anyone is going to answer or even post, but here goes:
BUMP
I also went back to stock and followed this guide:

You try getting a new sim card?

Does T-Mobile have any policy of replacing prepaid sim cards? If so, that sounds like your best option. Also, Samsung might have been angry at you cheating their system, and purposefully disabled your sim card. Make sure you take out your sim before sending it back for repair.
Thanks for the reply guys, much appreciated. I decided to just live with it and keep the captivate as a galaxy s wifi if you will for media purposes only like an ipod touch. My g1 will be a phone. Once the nexus prime comes out I will start up a contract and finally experience 4g speeds and w/e else I can get with a contract thats not available on prepaid.
Also I did not send Samsung the phone with the sim card in, idk how they must've known to block it. Thanks again.
Hello,
I currently have a Nano sim card and the Xperia Z doesn't seem to recognize it when I've fit it with the Nano to Micro sim adapter. Has anyone had success with the Nano to Micro adapter or does the Xperia Z only "recognize" true Micro sim cards?
My partner has the same phone as myself XZ she has the nano SIM working in her XZ it was fiddle getting the simcard in as the XZ has tray itself so I can't see reasons why you have these issues tbh I cut the simcard myself as she wanted the iPhone 5 till I got my upgrade she wanted this XZ now stuck with 3 contracts but hey hope this helps.. Just make sure it's all aligned up and it's inserted with SIM contacts facing down..

I have a nano sim with micro sim adaptor, works fine, just make sure you have the sim inserted correctly and up the right way.
I can't for the life of me figure out what this network problem is. I'm with Bell Canada and the sim card is not cooperating - haven't been able to get service and I inserted the sim card with the adaptor properly because it recognizes the phone number I have. Going to try buying a Micro sim tomorrow and see if that works, if not, this phone might have to go back :crying:

So what is your problem exactly? Can you make phone calls? Can you recieve phone calls? Is data not working?...
Anyway try this. Go into settings, then more under data usage, then mobile network settings, Access point names, do you have any listed here? If not go into network operators, should force the phone to search and list ALL the available networks, all the ones with the NO symbol will be other neworks you can't use on that SIM. Now select your appropriate option. Make sure data is enabled.
Data is enabled but I have the red exclamation point in the top left of the status bar indicating no service - can't make calls, no data, not able to browse the internet, etc. All the normal things you would expect to do with data, of course, I can still go on Wifi and such.
My network doesn't seem to be showing up when it searches for service providers, all I see is 2G/3G EXT under my available networks.

Maybe your provider is not sending out APN's/connection settings for this phone, or has the sending of APN's/connections locked down to known devices for their network, would pay to ask them first before you purchase another SIM etc.
xperia z no service
i have quite similar problem too. my problem is, i often got no service when i am outside my home. whenever i was in my home, the connection network is excellent. but when i went outside home like going to work, i got no service at all.
the only way i tried to get the connection back is by trying to call someone, then the network will be present about a couple of seconds and then no service at all.
please help me, i can make phone call when i am at home but i couldnt receive any phone call when i am outside. i am the opinion that the service provider cut my sim card wrongly. could it be the problem?
thanks in advance.
Hi Everyone,
I have purchased my Xperiz Z 'C6602' in the start of this year (2014). Yesterday, I faced a problem that my mobile was showing no Sim card detection. I have restarted my mobile many times, open the Sim slot and again placed it corrected but the problem persists. I have reset my mobile, check the aeroplane mode but all is well. I am wondering that how this happened because my mobile was working great. I used it at night very well and then after some hours at morning the mobile showed no network connection (detect no Sim) while the Sim was in the Sim Slot.
Please tell me the solution of this problem. Thanks
problems with 3 in 1 sim cards- solved
Had problems with my new Consumer Cellular card in a 6 month old LG phone (takes full size card) and a 1 year old Samsung 3 mini (takes mid sized card).
The original card they sent me was a 2 in 1 card and worked fine in both. When I had my number transfered from my original carrier they sent me a new card which was 3 in 1. It initially worked but then stopped in both within a couple of hours. They sent me new 3 in 1 card- same problem.
I read on line to put a piece of paper about the thickness of a manila folder between the top of the card and the metal bracket to apply more force to the contacts- worked fine in BOTH phones.
Why? Because the nano section of the SIM is thinner than the other two sections. To make matters worse, the side with the contacts is recessed into the card instead of flush to the face of the card. When it is placed in a non-nano phone, there is insufficient force on the electrical contacts.
Hope this helps someone.

Was looking up ways to get the sim card tray FIXED.. Brilliant solution, indeed. Paper ROCKS>> Once I put a few pieces of paper between the sim card and the tray, the sim is detected. Thanks a ton for sharing the simple and effective solution!!
I'm unsure if my problem has to do with Verizon or if I need to run a factory reset or try other options. Here's my story:
As soon as the phone arrived today, I unlocked, rooted, and flashed TWRP. No sim was in at any point since I didn't have a nano sim to use for it.
I tried cutting my Galaxy Nexus micro sim into a nano sim (apparently this works for some people), but the N6 states "no sim card - no service" so I don't think it worked.
Went to a Verizon store and got a nano sim for 28 cents, but the clerk couldn't activate it or bind it to my account since Verizon doesn't have the N6 IMEI numbers in their database. He told me to call support. Support was actually helpful, somewhat knowledgeable at least, and tried to activate the sim card over the phone.
Apparently the sim is pending activation from the phone, but I'm still getting the "no sim card - no service" errors. Does anyone know if this error means that it can't connect to the network, or if the phone thinks the sim is physically missing? There seems to be only one way to add the sim to the little tray as far as I can tell (gold face up, matched corner).
Has anyone else had similar issues? Should I try reverting (unroot/stock recovery/etc)? I'm not sure what the best approach is to activate the sim as I'm uncertain if the issue is still with Verizon or the N6.
EDIT: Everything is working now. For those of you moving from a phone with a micro sim, all you need to do is:
1. Cut the micro card down to the size of a nano
2. Drop it in your nexus6
3. Make sure wifi is off if you've already run through the setup. This was my mistake!
4. Give it a few minutes and you'll see the mobile icon flash LTE
It may help if you change your mobile network settings to LTE preferred.
Same thing happened to me. Did you try spinning the sim card around? The notched corner didn't look so much like a notch by the time I was done trimming...

Interesting. I trimmed off all the white plastic on the left and right sides so that I can rotate it or even flip it over. Going to try a few permutations... nothing yet. That's all it took eh?
That's all it took for me. Everything works. Data, voice, sms,mms... Everything.:good:

Still no dice. The gold face should be face up, right? I noticed that after a few minutes the error changes to "selected network unavailable", so maybe I'm putting it in right but now its just not being registered.
So far in my experience that message means you need to nuke and repave, including userdata.....YMMV
EDIT: Probably easier to get a new SIM from VZW, thats what I did

Thanks, I'll try a factory reset. I'm only running stock... can't imagine root or custom recovery would prevent the sim from being recognized. Perhaps when you click "skip" for the sim card part of the setup it can never be reconciled.
Factory reset didn't work either. Really irritating, it looks like the N6 that shipped from the play store came with android 5.0 instead of 5.0.0 or 5.0.1... possibly a development version from months ago?
I flashed the latest 5.0.1 factory images (boot, system, radio), then flashed TWRP, then did a factory reset to wipe data. At the setup prompt when I rebooted, it still says "insert sim card".
I'm not sure what else to try. If the sim card isn't activated I can't tell if that's why it wants me to insert a card, or if it physically thinks it is missing. I may need to order a nano sim to micro sim adapter, then put that in my old gnex and activate it that way, and finally move it over to the N6.
Does anyone have any other ideas or think I may have overlooked something?

All of the stock shipped with 5.0 so far. Not 5.0.0. 5.0.1 update notification "should" arrive after initial bootup
Contacts screen side up. It took a while to get onto the network initially. .#.#4636#.#. On the dialer opens a testing menu. There is a drop down menu, middle of the phone info page. Mine is set to lte/cdma auto
Thanks, never knew about hidden dialer apps. I set mine to the same. It's been a few hours and still no connection, so I'm going to assume the fact that the sim isn't activated is what's causing the phone to believe it's not inserted. I really need another phone to test with... if the sim card can be activated or work on another device, and still doesn't work in the N6, then it'd be a hardware problem.
Also good to know 5.0 is standard.
Update: I tried using the cut micro sim again, but this time turned wifi off. Looks like cutting the micro sim worked after all. I'm somewhat recognized by the network, but the sim used no longer maps to my account, so I'm getting a verizon webpage stating "device error" and to call customer support. I think if I can get verizon to revert changes made on my account yesterday back to the gnex with my old sim that this will work.
Moral of the story - cutting micro sim cards will work, but turn off wifi when trying to test your sim!
I'll report back once this is finally resolved. Hopefully this helps someone else.
Got it working - just had to get a new micro sim for my gnex, re-activate that device, then I was able to cut it down to nano size and load it into my nexus6. With wifi off this time, everything worked, and it connected to the network.
I've updated the original post with instructions for anyone else who might be having this problem.
Any advice would be greatly appreciated. I have searched and could not find an answer to my issue. I purchased a T-mobile variant Galaxy S6 it was stuck on the Samsung logo but I only paid $100 so I figured worst case scenario sell it for parts. I managed to get it to boot everything works except cellular service. If I remove the Sim it says "Sim Card Removed" Restart. After restart it goes immediately to No Sim Card . I insert the Sim and it says "Sim card Detected" Restart. After Restart No Sim Card???? Checked IMEI its clean, flashed stock via Odin, pulled what little hair I had left out. Any words of wisdom? Thank you in advance for your time. forgot to add no mobile networks option at all in settings?
Does the SIM card work in another phone?
yes sim card works in other phones
Could be why you paid $100 for it. If your SIM works in another phone then there is a issue with the S6 being able to read your SIM. Have a friend with T-MOBILE? Try their SIM card. You might have a picky SIM.
of coarse it's why I paid a $100 for it, no matter what I can get my money back out of it but I was hoping to be able to fix it. Tried several sim cards same thing it recognizes the card restarts no sim card. I was thinking it might be the sim card reader itself but the fact that there's no Mobile networks in settings makes me think it's software related? Oh well I guess parts on ebay here I come. Anyone need a new display LoL
Same issue
Hi there. I have exactly the same issue with an O2 unlocked S6. I used my Ee sim on it till two weeks ago when suddenly i lost all network capacity (same as you). Previously i flashed an unbranded stock firmware in order to get rid of the o2 logo (may seem stupid but that was what i did). After 2 weeks of normal use with the new rom suddenaly i couldn't give/receive calls /texts. Since, i tried wiping, flashing, advanced wiping etc but same issue. Any advice is more than appreciated.
Just wondering if anyone else might have had this issue I'm having and if there is any fix or work around for this. So I imported a Vivo X90 Pro Plus China variant and am currently using it in the US. I originally was using Verizon on it but was having network issues. Would work for a week or so (4G data,text,voice all worked), then would go to no bars and no service and would not re-connect with the network. I would have to remove the sim card, and re insert it multiple times or activate a new sim card and put it back into the phone for the phone to re connect and show signal bars and work again. So I assumed its just Verizon thus switched to a T-mobile sim and started using T-mobile with the device. With T-mobile worked better, got 5G instead of only 4G and everything was smooth for about 3 weeks. Then again I am having this same issue. Every week it drops service and says no service, I have to remove the sim card, insert a completely different sim and remove that sim and re insert my active sim for the phone to re establish and activate with the network.
SO the only thing I can think is that either the phone software somewhere is rejecting and blocking the sim or network after a while for some reason, or that the carrier (tmobile and verizon) are rejecting the phone being on their network and kicking it out. But if that is the case, why does it work again when I remove the sim, insert a different sim and re insert the same active sim back again. Makes me lean toward a software lock or something.
Any ideas? Thanks guys.
Im now in US too, currently running on mint and i didnt see any problems with network issues, most of time in on wifi but every time i need data it works fine. Only difference is im running european sim on slot 1 and us on slot 2.
oh, hmm not sure what could be causing this issue for me. I'm thinking maybe one of the installed Chinese apps are interfering with it but not sure.
I'm on mint as well (uses T-Mobile network).
Never had any network issues.
It might be worth trying to restore the phone and try the newer 2.6.4 debloat script as a baseline.
Then after that you can try removing some of the additional system packages like vivo store or vivo.pem (although the jury is mixed on whether it's useful to do that).

I may have to try that and look into it. I'm not too familiar with doing any rooting or running adb stuff (been years since I did that sort of thing) so worried I might mess something up rather than fix it lol
