[Q] Why isn’t sim card being recognized?

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.

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!

[Q] Voice: Out of service / Data: In service HELP!

I have lurked so much around XDA and still I have no solution
I own a Moto X XT1053 on Movistar (Mexico)
Everything was working fine until I got my SIM card replaced. Now Voice and SMS don't seem to function but Data from my carrier works fine.
When I try to dial I get a "Mobile network not available"
I have done "fastboot oem config carrier (all possible options) No luck.
I have switched from 4G to Edge since that seems to be the solution for many but that didn't work for me.
Yes I have searched for networks and selected "Choose Automatically" No luck.
I have flashed back to stock firmware using T-Mobile's firmware (which has always been my solution and everything worked flawlessly) but now that doesn't work. I've actually not a fan of custom roms I only do stock and xposed the [email protected]#$! out of it but even a clean stock doesn't seem to fix it.
I even went to Movistar and they believe its my phone since they tested my sim on another phone and voice worked on theirs.
Any thoughts on what could be the solution? Please Help!

Check the APNs?

I think your first statement supersedes your latter statement and everything in between. Just because your new SIM worked properly in another phone doesn't mean it's guaranteed to work in your moto x. Maybe for some reason your moto x is reading the sim as a data only Sim, or maybe it's registering on the network as a data only Sim.
did you cut the Sim to nano or did it come as nano?
Did you try a different SIM in your Moto X?

They did try another Sim on my phone and same, no good. Voice seemed to work on other phones. I personally believe my phone was blacklisted. When I went to get my Sim changed I forgot to mention the account was under my moms name. Now my new Sim is under my name but with the number of another owner (my mom). Which could explain why I get no voice or SMS but data works fine. I am actually on my way to customer service right now.

Well just returned from customer service. No good. Its the phone itself. :/

Have you solved the problem? I'm using Samsung Galaxy S5 and has similar problem... After couple of times of change rom the problem occur... I'm not genius and I have struggle with this problem for more than 2 weeks... See whether we can work this out...
My situation is:
1. Voice: out of service, data: inservice;
2. IMEI: seems normal
3. I tried two SIM card with different ISP, neither work;
4. I also try that two SIM card on my iphone4, both work well.
5. Since my phone is G900F HK version, and I'm currently in UK, so I tried latest UK stock firmware and latest HK stock firmware. Same...
I had do some searching and said that there are few reason that might lead to this problem:
1. IMEI error. Flash rom may damage your partition, if your IMEI is 0046*** or 0000*** something then this is the case;
2. Baseband related. Just flash some wired rom that no capable with your local bands?
3. still looking...
Good luck then...

Same thing
Did you ever solve this? I am having the same problem on my Moto x Pure 2015.

[Q] Calls Immediately end On TMobile Nexus 6 flashed with VZW stock image

Good Morning Group,
I have VZW service. The Nexus 6 is from TMobile. In my infinite wisdom or rather the lack their off. I decided that I was over not having data while talking. I downloaded the VZW LMY47E image and followed the instructions found in the Nexus 6 general sticky roll up. How to flash factory images.
The short method did not work but the long method did. I rooted it and added TWRP recovery. Apart from that I left it stock.
I dialed *#*#4636#*#*. and turned off VOLTE provisioning flag. Then I checked for enhanced 4G under phone settings and it was enabled.
Awesome right....Wrong. I decided to test it. All calls immediately end after starting them flashing 00:00 time stamp. I decided to pull my sim and put it back into my S4 and dial *228 option 1 and I can make calls using my sim. Something must have went wrong.
What that is I have no clue.
I was thinking of flashing the 5.1 TMobile image but everything that I have read suggest that if you are on VZW you should use LMY47E.
As you can imagine not having phone service kicks rocks. I figured Id ask before flashing and or making anything else worse.
Thanks in advance.

*228 should never be done on an lte device.

Flashing another factory image will do nothing to help your problem.
I agree with the above suggestion of starting with a replacement SIM.
And whatever you do, DO NOT TRY RELOCKING YOUR BOOTLOADER. It will not help, and you may brick your device, unless you follow @Evolution_Freak 's guide.

FML will they give me a new sim for a phone that did not come from them? Even if the sim was locked into 3g shouldn't I be able to make calls?
Edit: I put my sim back into my S4 and it displays 3G like you said. I can make calls on the S4 but no on my Nexus 6. I put the sim back into my nexus 6 and it displays LTE but I can not make calls

No they won't if you tell them it's for your N6. You'll have to tell them it's for a "legitimate" VZW phone.

So basically you are saying just go to a Verizon store and ask for a new nano sim and ask them to activate it? Or do you suggest asking for a sim for my S4 and cutting it down to size again?

Thanks for the suggestions. I'll try to sort it out.

I decided to try reflashing the LMY47E image again. After doing so I was able to get 3G and make and receive calls. I went to VZW and they gave me bloody hell about getting a replacement sim.
Essentially they were not having it. They wanted to see the physical phone that the card would be activated in. I went back to my car and gave them my S4. To make a long story short they gave me a VZW sim for my S4. Got back home and cut the micro down to nano. I now have LTE service.
But I do not have VOLTE. I dialed *#*#4636#*#* and turned off VOLTE provisioning flag. I have enhanced 4g calling under phone options. But I can not browse a web page or talk on the on the phone while using GPS etc. Is VOLTE supposed to be turned on or off.
With it off I do not get the enhanced 4g calling options. With it on I do get enhanced 4g. Either way it doesn't work lol. Any suggestions would be greatly appreciated.
I'm just happy to be up and running again.
Thanks once again for your time and patience with my N6!!!!!!!!

Do you have advanced calling activated on your account? I don't believe that the S4 has advanced calling. You may have to put your sim card into a VZW device that requires it and then have them activate the feature.

Yea.... Did you ever activate the service on your account. You need to login in the website or call and turn the feature on. Dialing weird numbers and turning flags on in your phone won't do jack until the service is turned on within verizon.

Unfortunately I am a member of a family plan. I will speak to my cousin who is the account owner and ask him to double to check and see if it has been advanced calling and HD calling has been enabled on my account.

i can pretty much say thats your problem. it isn't turned on by default so it needs to be turned on. no amount of flashing software or hitting buttons on your phone will help. I think you can even call the 611 number and when it gets to the voice prompts just say advanced calling one point zero. it should try to turn the feature on within that line.

The S4 had dual antennas so there was no need for the Advanced Calling feature. The Nexus only has a single antenna and requires Advanced Calling to be enabled on the account and the device in order for it to work.

Thanks for the number. The CS Rep said they can not make any change to the account because I dont have the password or pin.
Ironically one of the main reasons for getting a new phone was that my S4 wanted to power off randomly and it would be a chore just to get it to power back on and stay on. This time it would not turn at all so I was forced to call from my old thunderbolt.
I called the number you gave me while surfing the web on the phone. The CS Rep said that any 4G / LTE phone can use data over voice except for iphone due to their antenna construction. I guess its true I was just doing it.
But anyway it really shouldn't be a process just to get data while talking on the phone with the nexus.
The phone they have listed for my account is a S4. They said advanced calling and HD calling will be available for the S4 when they provide a software update. He had no clue to when the update would be released.
Just for Sh1t and giggles I inquired with the CS res in regards to purchasing a phone from google and using it. He said that I could go to a Verizon store and they would add it and give me a nano sim. I just thanked him for his time. I guess thats true right until you walk in their with it.
My nexus is from TMobile and from what I read people across various forums are having issues with getting their Nexus 6 added to their account regardless of where it came from.
Seems like verizon is really working hard to make the nexus 6 experience a pain in the ass. I dont need or want HD calling. Is asking to talk and look up something on the web or use gps to much to ask for....

no problem. you dont even need to speak with anyone in order to activate. some people reported just using the prompts, speaking with a machine it was able to turn it on. either way, good luck and glad you got some info.
I literally just got back from best buy with my unbranded unlocked nexus 6. they didnt have any "verizon versions". I will be cutting my sim card thats in my GS4 and throwing it into the nexus so i wont have to deal with verizon. i already had them send me a nano sim so just in case i have a backup. if i completely mess it up, ill go back to verizon and get a new sim for my GS4 and start over again

Thanks for the clarification. I did not know.
How should I go about this? I called and they said the phone that is listed is a S4. Currently advanced calling is not enabled for the S4. They said I would need to do a phone swap and or sim swap for a newer phone. If the phone is not listed on my account/ number what do I tell ask or tell them so they will enable it?

It works fresh out the box. Mine did and it was from TMobile. I didn't do factory resets or anything insert sim and load up my apps and enjoyed.
I used a sim card cutter that I got from Amazon. Cut it popped it in and everything was lovely. I didn't notice that I couldn't talk and use gps until i was actually driving. The sim cutter is a good investment because it comes with sim card adapters that will allow you to use your sim in any phone.
I wonder how the people got it activated using the prompts. Did they call from their nexus or their old verizon phone?
The only reason I decided to flash the LMY47E rom is to get data over voice. Hopefully I will get this sorted out sooner than later.

Tmobile worked on Verizon phone for a day then stopped. Help?

Just bought a used S8+ on Craigslist. Posting on here since it seems more people have the s8 and its the exact same thing when it comes to network. Anyways everything worked fine, it's unlocked, it has all APN's available in the settings for other providers. It worked for a day, but an hour ago stopped working. Checked to see if IMEI is clean, it is. Tried other sim cards from t-mobile, no change. Tried the sim card back in my old phone (HTC M9) and it works just fine. On notifications is it saying "SIM card is not from Verizon Wireless". Thats it, no other error messages.
I'm really lost, don't know what to look for or what else to check, anyone have any input?
