[Q] Why isn’t sim card being recognized? - Captivate Q&A, Help & Troubleshooting

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?
Sent from my I897 using xda premium

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.

Get a new sim card?
Does your sim card work in a different phone?
That happened to me once. I had to return the phone. I was unable to get it to recognize the sim card.
Different rom didn't help either. Even when I flashed back to stock... no sim. It was a refurb so a new one was easy to get.
Hope you get it worked out.

This happened to me earlier this week. Flash to stock and then back to the rom worked for me

Clean contacts on sim card. Factory reset. If that doesn't work call Rogers for replacement.
No warranty you can replace the simcard slot its a daughter card I think you can order from globalpartsdirect
I have the exact same problem. Again it happened with a warranty phone I just received today. It occurred while trying to root the phone. The SIM card from my wife's iPhone does not work in my phone either. However, my SIM works in her phone. I've tried just about everything I can think of at this point other than running Kies (my next try).
BTW,
Unlike my original Captivate, this one came to me with Froyo already installed.
Under Menu /Settings / About phone /Status /Network what does it say ??
If it says "Unknown" you could try just flashing ur modem again.
I am having the exact same issue with a refurbished phone from AT&T and insurance gone im out of luck unless there is a easy solution.
Hello Everyone, So this is my situation so far:
I have a Samsung Captivate with unbrickable mod added. I flashed with Heindall to 2.2 froyo on linux. The SIM card is not recognized. I have triend 2.1 and 2.2 and 2.3 one clicks in windwons with no luck. I tried to mess with IMEI and elfs file. Results were that the lines i was suppose to change on nv.bin did not exist (no lines in file i was attempting to correct). So at this point and time can i conclude this is absolutely not a software issue? Problem two is if this is a hardware issue and not a software issue. Where do i begin? how much is the price for replacement? How hard is it to do? I have tried flashing with everything off the phone (sim and sd) Im a bit lost at this point. Any help would be great.
Update: Spoke with Adam and he says its not a software issue. I also spoke with the guys who did the soldering and said the issue is not coming from the soldering. I am thinking maybe when the phone was taken apart something got loose? Any thoughts anyone?

[Q] Possible to use Samsung Vibrant on AT&T *without* data plan?

Hello XDA! After numerous searches and lots of contacting my local psychics, I've still been unable to find the answer to life's #1 question:
If I buy and unlock a T-Mobile/Samsung Vibrant, I know I can use it on AT&T. However, if AT&T has IMEIs on file for the device, it will be detected and upgraded to a data plan (thanks AT&T). Since the Vibrant is part of the GS line, does anyone know if the Vibrant will be detected as a smartphone?
Thanks in advance for any help!
EDIT: and this thread was no help and in the wrong place.
A wee bit late...
I'm a wee bit late, but if anyone wants to know:
I've had my Vibrant for a bit now, and so far, no upgrade. I'll keep this thread updated if I do get upgraded, though.
Dd you just put the at&t sim card in the unlock vibrant? Or do I have to disable the data connection to prevent at&t to detect the device? And does MMS works without data plan on vibrant? Thanks in Advance.
Sorry, but I don't use MMS at all. I have data turned off both at the phone and at AT&T, but if I understand correctly MMS should work and data should not get you detected (other than using excess data).
Samsung Vibrant on AT&T phone only plan
I have a Vibrant I use on AT&T with plain phone service only & enjoy the Android world in Wi-Fi areas. I have "Mobile Networks - data enabled" turned off in setting so it does not use any of AT&T precious data. I am not sure if this is in stock phone program or not, I have custom ROM installed. Every time I update my phone with a new ROM I make sure I do not have the SIM card in until I have the data turned off because the ridiculous fee for pay by use. Anyway I logged onto AT&T and set my phone to a dumb phone on their list of phones, waited a few days, and called AT&T. All they could quote to me on the Vibrant phone with their SIM card in was it was a "non AT&T branded phone". I got data removed no problem but did require a phone call - unable to do online. This has worked well.

[Q] Swapping ROMS on Straight Talk

I just got straight talk working on my ATT Note 3. (SMS, MMS, data, calls inbound and outbound working) But I heard that the SIM card is locked to that phone forever. And I heard that flashing a new ROM will make it where the card won't activate on the new ROM. Then i would have to spend the money and buy a new card Is this true? or is this with the IMEI only? also I can't seem to check my data usage on Straight Talk. When I text 611611 "usage" it force closes the phone. I'm thinking it could be the ROM so that's why I was discussing about how safe it is to swap ROMS on straight talk and if they can be re-activated after a ROM flash.

the regional unlock thread has the side affect of unlocking the sim as well"you wont need this except if you want to travel international ". And changing the rom has no affect on your already activated sim you just have to re-enter the apn settings into the new rom. And your sim chip is portable from one at&t phone to another as long as it will fit in the phones sim chip slot. So no you wont need a new sim card if you change roms. I really wouldn't advise you to change roms tho. If you don't know what you're doing you could brick your phone.

I have straight talk and I have switched roms no problem.
I'm currently off contract and using "Go Phone" by AT&T...No apns change ..works flawless...45 bucks..unlimited talk, text,mms.video mms...1gb data...

Data connection OK, but no voice calling

im using my SGN4 in a brazilian carrier, and everything was working perfectly till from nowhere the phone lost connection from network.
I was unable to make phone calls , but strangely my 4g connection was on i could browse on the web normally. How this is possible? I popped out the sim card and tried in another phone, it worked normally. I also tried another carrier on SGN4, i was ok too. Anyone have an idea what is going on?
factory reset, problem persists, i have data connection, but cant make phone calls.
Is the phone unlocked. Yes I have to ask.
BAD ASS NOTE 4
Yes it is as I told I was using it with my Brazilian SIM card
Is their anyway to check if it still unlocked. I know some people said when they unlocked it was a temp unlock. Did you check APN to make sure they set right for that carrier
BAD ASS NOTE 4
hey guys, im back to this post because the problem persists.
Here is the scenario:
I bought the phone from a Swappa Seller. Phone is t-mobile branded and was in the box, Brand new.
http://swappa.com/listing/ZPB505/view
Brand New Samsung Galaxy Note 4 SM-N910T White ( UNLOCKED) 32GB
Phone is brand new in its original box. The phone has never been used. All Accessories are still sealed in plastic - The phone model is SM-N910T. This is a great deal on a BRAND new - NEVER USED phone!
This phone is guaranteed to work with AT&T. There is no regional lock whatsoever

Can anybody tell me why a T-mobile unlocked phone won't work with T-mobile?
I used the phone on my carrier and it was flawless. Everything was fine till suddenly i lost phone signal. It always show "NO SERVICE" message now, but strangely I still have 4G Connection. I can use the phone to navigate, not to make phone calls.
So I swapped carriers, and the phone was working ok, phone calls, data connection.... then the thing happened again: no service, but i have 4g LTE connection.
Inserted a third sim card, from another carrier. Phone is fine, workin as it should! But this is not my main sim card and i would like it very much to work with ANY carrier. Do you guys have any idea what the problem is? Factory reset did not work at all. For the others sim cards, it recognize the network for a second and then "no service". How can i have data connection if there is "no service"?
Im really desperate because i payed a lot for this note 4... Maybe if i root the phone and flash another ROM?
help please!
Is that possible that previous owner reported is lost and now imei is blocked? Your carrier may participate in that program.

thank you im going to check with my carrier.

Sorry to revive this old thread, but has anybody figured this out?
I too have data with No Service (no voice) when roaming to the USA from Mexico (Telcel). My Note 4 was purchased on T-Mobile USA (contract free) but got it unlocked by gsmunlockers.
Everything was perfect until I got my Note 4 upgraded to 5.1.1 rooted. I have tried several other ROMS and Basebands with no avail.
Any ideas?
Cheers!

Please help, No Sim Card/Emergency Calls only

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.
