[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:

with no success.

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.

Unlock issue with UK i9305 - won't work with Three (3) network sim!

I'll try and keep this breif but getting pretty frustrated with this...
I bought this handset sim free from T-Mobile UK. It was brand new and sealed. When inserting my Three(3) sim it would say "invalid sim" - which was expected as it was locked to T-Mobile. I paid a third party UK company called mobileunlocked.co.uk who have a very good reputation and lots of good reviews for an unlock code so I could use it with a Three (3) UK 3G Sim card. I received the unlock code and an un-freeze code and used both several times, resulting in "unsuccessful". Thinking it was a bad code, I paid ANOTHER unlocking company off ebay (again, reputable) and was supplied with the same codes and the same results but a slightly different method which involved entering * and # keys before the codes in the code box. This resulted in a popup saying "Network control code is blocked".
Following this, I tried the *#197328640# method to access the hidden menus as detailed in this thread http://forum.xda-developers.com/showthread.php?t=2014982 (this has been proven to work with Note II, Galaxy SIII and Galaxy SIII LTE).
I followed that guide to the letter and restarted the phone. At first, I had hope as there was no sim lock code entry box, however I waited and waited and waited and the phone did not pick up my Three (3) signal, despite it no longer saying "invalid sim".
Basically, it just shows several bars but does not pick a Three(3) signal or any date. I have tried manually selecting the network and manually entering APN settings, but I get the same result. When I try connecting manually it just says "Cannot register on network".
-I have tried using this sim card in other phones, it works OK!
-I have tried using other network sim cards (Orange, T-Mobile, EE, Vodafone) and they all work.
-I have tried using a different Three(3) sim in this phone and it still doesn't work.
I can't return it to the T-Mobile store as the warranty is invalid as I have unlocked it (or so I think!). Can anyone help? I know three(3) sims are compatible with this phone as others on this forum have stated they are using Three (3) sims in unlocked i9305s.
Any idea why my unlocking codes that were valid wouldn't work and why it said "Network control code is blocked"?
Any idea why my Three(3) micro sims won't work but other networks do despite this phone being compatible with three (3) sims?
Help!

It doesn't appear that 3 UK has any publicly available LTE network at this time, but that they are rolling one out. Perhaps it is physically available and being picked up by your phone, except 3 isn't allowing just any sim card to register on that network at this time? Try disabling LTE and attempting to connect again.

I know I won't be able to get LTE as Three (3) aren't offering LTE until Q3. I am perfectly happy just using 3G. I have tried disabling LTE and using 3G only and the same things happen.
I have tried 2 different Three (3) micro sims in it and it still won't register on the network. I know Three(3) sims work in the i9305 as others have unlocked their's and used Three (3) sims.
It's either something wrong with the unlock, something wrong with the hardware or something isn't enabled/disabled. Like I said I've tried automatically connecting and manually entering APNs and still NOTHING.
Frustrating having spent over £450 on a brand new handset which I can't return as warranty is invalidated through "unlocking" (which hasn't unlocked it fully!)

Shouldn't be a problem to be honest. Have you tried calling three to say that you're using the i9305? I love three and their unlimited data plans I plan to do this once samsung/EE unlock my phone.

Hi,
I am in the same boat, I actually got the S3 LTE from EE in December (GOT IT FOR 359).. Initially, it worked with three after unlocking via xda..*#197328640# method ..But it stopped working or it was working intermittently...
So tried rining three..they said..ohhh our network is best and our (three) sims will work only in three mobiles..
Anyway I tried all other methods..re-set..factory etc..
Finally sent the mobile to Samsung...
after 10days, I got it back...Now as soon as I insert three sim..it says invalid sim..So tried *#197328640# method again..unfortunately..i can't do that as (the last option INITIALIZE...) does not show up now..
Anyway managed to get unlock code from ebay...NO USE..it shows the same problem as yours.."network control is blocked"...
Donno what to do??? might ring samsung again tomorrow...
Have you tried speaking to T mobile about getting it unlocked????
If you find any answers..pls let me know
Thanks in advance

I'm having the same problem. Any updated on how things went with T-mobile or does anyone have a fix?

Should I cancel my order?!
I just bought the S3 LTE i9305. I purchased it as an upgrade and its arriving tomorrow. I wanted to give my sim to my mother and keep the phone to use with Three's DC-HSPA+ which will work on the S3 LTE. So can I unlock it or will it be facing the same problems as mentioned in the thread. Sorry for not helping out, ama noob and GOOD LUCK! :good:

I recently put in an unlocking request at EE. They get a samsung unlocking code directly from Samsung. So I'll give this method a go. I am getting my Sim Card in soon from three. Decided to jump the boat on to the one plan @ £25 a month. =) EE's london signal is pants. =(

I tried to get an unlock code from T-mobile, they said that Samsung wouldn't release it for another six months, since it's a new phone. Even though we've been with them for donkeys years!

Right today, I recieved my sim. I'm glad to say everything works. I'm getting around 8mbps down and 1mbps up in West London.
If yours doesnt work then it probably is a damaged sim.
Tell T-Mobile you want to speak to someone that knows what they are talking about. It takes up to 60 days for direct Samsung unlock code. You might have to pay a tenner but worth it jn my perspective. I'm glad I have unlimited data again. It feels like freedom. No Joke. o2 Used to do an unlimited tariff and I loved it. There reasoning was to improve their network but instead it made it worse. I know Three arent known for their calls but they certainly know what customers want and thats data.
PS how do I know if im getting the optimum speed?

I think you have updated the software via OTA.. you need to downgrade to I9305XXALI5_I9305EVRALI5_I9305BVALI5 (this is for people who have got phone from T-mobile). Download from Sammobile.com, flash via odin (this wont affect ur warranty as this is stock firmware and doesnt increase the binary counter).
once you are sure that you have the above software, then follow the instructions on the below in first post in the mentioned link, again no rooting involved:
http://forum.xda-developers.com/showthread.php?t=2014982
People have confirmed that after unlocking via this method if you go ahead with OTA, you will still have the phone unlocked.
I have followed the above procedure but havent updated the firware and have not used the phone yet. But its unlocked and I have tried using Three UK sim, it works,
Do let me know how it goes.

On the site, it says it's for EE, is that still ok? I know T-mobile, Orange and EE, are all pretty much the same thing now, but I just want to be sure. I wouldn't want to put something that starts putting EE logos all over on boot up etc. The one that came with the phone doesn't mention anything about T-mobile on boot up.

It won't EE is unbranded

Thanks... I've zapped it with 4.1.1, used that trick, and then allowed the 4.1.2 update + plus another update of some sort through OTA, and I'm now using O2 happily! 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.

As far as I know it wasn't ROMed/rooted. It was stuck lollipop. Ever Since I put my sim I'm mms,sms, and data would work. The phone was locked to AT&T though. I sold it the guy who bought it inserted his AT&T sim and everything worked right away. I put my sim in my lg g2 and had no issues with my calls..

SM-N950N Note 8 unable to make or receive phone calls - everything else works fine

So I bought a SM-N950N Note 8 in October 2017 and has been great until now where it cannot receive or make phone calls. Everything else works fine - SMS, mobile Data, everything. Just unable to make or receive calls.
I have done everything that I have found on the internet from resetting network settings, resetting cache partitions, factory reset and nothing works.
I have made sure its not hte sim card by putting it into my old S5 and it works fine.. it currently is my phone until I figure out the Note 8.
Does anyone out there have any other suggestions?

Check your APN settings.
Check another sim card in your note 8 (friend's sim card or a new sim card (old one might work on s5 but might not on note 8)) or Take it to your carrier and let then try their sim card and see. Point is try another or different sim card!
Might to check if there is no dust or dirt in the tray or dirty sim card.
Last resort BACKUP your phone and factory reset.

Take your device to the high street retail branch of your cell provider and let them take a look at your device. They will probably reinstall the network settings on your device

So basically what was going on was that when I need to make a call, the note 8 needs to drop from LTE to H or H+, which I observed it doing on my samsung S5 and a Samsung S7. For some reason or another, the SM-N950N KT version is stuck in LTE only mode and wouldn't downgrade to H or H+ and therefore couldnt make or receive calls.
The fix? Since I bought it back in 2017, way past any warranty period - I installed Dr Ketan's ROM and effectively changing the CSC to Australia region and within 15mins all fixed!
If anyone else is having a similar problem, I was on the Kogan network [vodafone].
Thank you Dr Ketan! https://forum.xda-developers.com/ga...t/29-09-17-dr-ketan-rom-jio-volte-n1-t3681163

I know right! It was just a tablet before - had to use my old samsung s5 as a phone.
It is all good now - Dr Ketan's ROM is amazing - Loaded my note 8 with an Australian CSC and it is perfect. No bloatware, high configurable.
