Galaxy Tab - No SIM detected - Galaxy Tab Q&A, Help & Troubleshooting

I am trying to get the 3G working on my Galaxy Tab.
I have tried this SIM unlock - http://forum.xda-developers.com/showthread.php?t=843323, even though it seemed successful it still does not appear that it recognizes the SIM.
I re-stocked the device back to Overcome and the device still will not work with the SIM. I have tried setting the APN when JB was installed however that still did not work, the APN did not save.
Does anyone have any suggestions on how to get this going?
Cheers!

You have the separate the issue logically.
Is the SIM working, it is found, it found the network, has signal, can make calls and receive call. Can SMS and receive SMS, no 3G but has edge?
If that is the issue, no amount of unlocking will help. APN will help probably.
So what is your problem again?

1. SIM is working - tried in my Galaxy Nexus and found a signal.
2. SIM was bought from a store - pre-paid.
3. See 1. (network & signal)
4. See 1. (make/receive calls)
5. See 1. (send/receive SMS).
6. SIM gave 3G network coverage
The Galaxy Tab simply says "no SIM found" however reboots when adding/removing SIM (with gingerbread 2.3, Overcome 4)

I should have rephrased.
When i said SIM working, i wasn't talking about the SIM. I should have said is the SIM working in the tab. Then the rest of the question also about in the tab.
Ok. Not detected. No point trying apn.

If it makes any difference I have used a SIM in the tablet before, it was a while ago and it was before I wiped back to Overcome 4. Back when I was using ICS/JB [not sure which].
So the tab is definitely capable of SIM usage.

Anyone have any idea? Would really appreciate it.

No T-Mobile network

I took my girlfriends S1 on holiday with my 3 network sim in it, when we came home I put her T-mobile sim back in, now it will not connect to the T-Mob network, it will connect to 3G? Putting the sim in my SNote and all is well. I have since install a custom rom to see if that would help but still no good.

Believe me I have taken the sim out and tried it in the "wrong way" lots of times. I have also looked at your solutions page before, very helpfull. But why will the sim work on one network but not on another, and the non working sim will work in another phone????

Check the modem on both phones.
If the phone that doesn't recognize T-mobile has a different modem, then load the modem that the phone that works has through oden or CWR.
Hope you know how to check the modem and load new ones.
Good luck

This will happen as T.Mobile may be using a different Radio band ..most likely you changed the APN and Network settings when you used it with another SIM Card , whilst abroad ...all you may had to do was check your Network Settings in menu> settings>wireless and Networks> Mobile Networks and reset it back for the T.Mobile network, initially
To understand this better read this http://en.wikipedia.org/wiki/UMTS_frequency_bands
at the same time since you upgraded by flashing to JB, you may have to select a new modem that is suitable for JB, you will find all modems at My Android Collections
Data but no calls
Me back again, I have tried all xx modems, reverted back to stock rom, then GB, them back to CM10. When I first turn on phone it finds network (i'm on a giffgaff sim now) it says GiffGaff at the bottom of the screen for about 2 seconds, then it says emergengy calls only. I can still connect to internet. APN settings correct, IMEI correct, In Settings - About Phone - Status, i'm connected to network, service status = out of service, mobile network state = connected, my phone number = unkown. Where can I go from here?
More
Another thing I have just noticed, when I take the sim OUTwhen the phone is still ON, the "no network" on the screen turns to giffgaff,

Try to set your phone number by following this guide , it was written for a Korean version, so just adjust it for your phone version.

This is probably because T-mob covers only particular places the frequencies this phone uses http://theunlockr.com/2013/07/05/htc-one-sprint-specs/ vs t-mob https://t-mobile.jive-mobile.com/#jive-document?content=/api/core/v2/documents/4988

Is there any solution for this problem ?
Is there anything I can do to fix this problem ? (different rom or radio...etc..) Or I have to give up the phone... Cause it is too much headache to "searching for network" all the time and miss all the call with no service on the phone without knowing..
Thanks

well, I am not an expert on the tmobiles network, but going by what lazybozz, said, I seem to remember tmobile using different bands than the other carriers, so what you may be experiencing, is the phone being in the vicinity of multiple towers, but not all of them are within the band that the phone supports. So its like the phone doesnt even see those towers. On a side note, this issue caused alot of chaos for those who unlocked iphones about 3 years ago, they could use EDGE on tmobiles network but not 3G, so i assume this is a similar situation. So long story short, yeah you probably cant fix the problem, unless you get a quad band phone. I could be wrong, but it does sound like a logical reason for the issue you are having.
as elvisypi said above, Its the freq that T-mobile operates on in that area. If your getting T-mobile at all in the states then you have already flashed a radio. However flashing any other radio is not going to give you the freq that tmobile uses, Its not a software limitation its a physical hardware limitation.
Thanks for your reply, do you know any app out there that monitor and alarm you when the network or signal is lost ? That works with 4.3 ?That way at least you know the phone is offline ... some of the apps I tried is anything at all ...
Thanks
Have you tried an app like tasker? Its essentially an automation app. It isnt jist for your use. Its for many different functions. Jist look on the app store for tasker. That might help

AT&T unlocked 2014 x not working on tmobile

I have an unlocked AT&T xt1097 but it won't register my T-Mobile Sim card. It registered for about 3 minutes, got a welcome to T-Mobile text and that was that. My phone number shows up in settings, but it shows I have zero service. I've reset, and rebooted several times to no avail. My sim works in a nexus 6 so it's not the sim. Imei os clean. Does anyone have any ideas what it could be or how I could get it to work with my T-Mobile sim?
When you say unlocked, unlocked Sim or unlocked boot loader?
sim unlock. As far as I know there's no boot loader unlock.
Could it be that the imei isn't in T-Mobile's data base since it's an at&t moto x?
Edit: went and put the imei in to tmobiles imei checker and it couldn't figure out what device it was and if it was okay to use on their network. Now I just need to verify with T-Mobile and see if they can register the imei.

did you ever get it to work? i am experiencing the same issue. it connects to my friends AT&T network fine but with t-mobile it just says "cant register" etc,etc.
Change the APN settings
I have had a problem like this with my unlocked phone and AT&T, but when they set it up in the AT&T store they fiddled with the APN settings. I had to do the same to get my wife's unlocked Lumia 635 to work on the T-Mobile network. Try the values used in the link attached and see if it works.

I was able to connect to tmobile network some times, able to make calls. No data connection at all. I played with APN settings and everything else. any help..?
I have an unlocked ATT x1097 and it works just fine with tmobile.
You just have to MAKE A NEW APN SETTING.
When you put a tmobile sim in it, it will automatically create a couple of T-MOBILE apn settings. Just leave that as is and create a NEW APN SETTING with same info you can find from Google. Select that as your data apn. And reboot the device for the best result. It should fixed the problem.
For those of you whose sim does not register into tmobile network; i think it could be one of the following reasons:
1. Original ATT modem does not work well with tmobile frequency in your area
2. The device is locked (stolen, non-payment, etc)
3. The device is broken
4. Your SIM card is damaged
As long as you are at the home screen with tmobile sim, your phone is GSM UNLOCKED, and it iwill never lock again.

Just wanted to say thank you. My T-Mobile SIM wouldn't connect and I even went to the T-Mobile SIM store to get a new SIM Card but it didn't help. As you stated, adding a new APN setting was the only thing that worked.
For those of you who want to unlock your Moto X, I purchased a code on eBay for about $8 and received it within 6 hours. I would post the link but I'm afraid it might be considered spam.
What type of data signal are you getting? LTE?

Nice. Where did you get your unlock code?
I don't know about OP but I have always used swiftunlocks and have had great luck. Got my N6 from ATT unlocked through them without issues as well.
http://www.swiftunlocks.com/unlock/motorola-at-t-tmobile-worldwide
I noticed that sometimes phone picks up apn without issues and sometimes you have to restart so I just restart every time I make a change to be on the safe side.
Just in case anyone else has the same issue as OP, you should use the
Code:
epc.tmobile.com
APN, NOT the
Code:
fast.tmobile.com
one.
The fast.tmobile.com one would not let me register on the network. epc one did immediately.

Hey, I know this post is kind of old but I am currently having the same problem with my moto X 2014 going from At&t to T-Mobile, were you able to get it fixed and if you did, what did you do?
Any luck? I've just come accross the same issue. Got phone unlocked, and bought a new sim and activated. I'll get like 3-4 minutes of service randomly here and there, but about 99% of the time no service. Tried multiple variations of APN settings that I've found online. No luck
Fixed all my seriously annoying connection problems by flashing the 4.4.4 modem.

I just gotta upload the 4.4.4 modem from my pc, will do that later for you.

Neither one works for data... Just got it unlocked from swiftlocks and I can get voice, but no data :crying:
Someone help!! ...plz
Anyone ?? T-Mobile reps are mostly useless, and keep telling me that my device may have been ' re-locked ' to AT&T after a hard reset !! I know that's not the case because I've thrown in a Vodafone sim and it recognized it ! The sim unlock was purchased from SwiftUnlocks and the phone took it in one try w/o any issues!
Now, I can't even get voice to work... All I see is ' No Service ' and when manually trying to register with T-Mobile, it says ' unable to connect to the T-Mobile network. Please try later '
Someone please help out!!

Galaxy Note 5 SM-N 9200I mobile data & calls issue

Hello! This is my first post on XDA-dev and I'm trying to get some help from anybody who had this issue with his Note 5. The model is SM-N 9200i, the phone is registered on Orange network in Romania. After a few months of using the phone with no problem at all, it began to behave really weird...at first just now and then but it became a permanent issue in the next 2 months. So here it is: when I have the mobile data on, I can't make or receive calls..if somebody tries to call me, it goes straight to the voice mail. Also, even though the mobile data is on, I have no internet acces at all..the icon shows H or H+ (completely lost 3g or 4g) but can't acces the internet. The wi-fi works great, and if I turn off the mobile data, I can make and receive calls with no problem. Currently I'm on Android 7 but this issue had started since I had Android 5.1. I've surfed the internet looking for a solution, but couldn't find one, not even on XDA forum. It's really annoying having to wear my wi-fi mobile router in the pocket so If you have any ideas, please let me know. Sorry for this long post! Regards, F.

Do you know that your APN settings are correct? Have you tried your sim card in another phone?
Yes sir, the APN settings are ok. Also, I've used the sim card on two different phones and I had none of the problems I've mentioned. Perfect internet acces (4g present, although it dropped to 3g when I made a call, which from my understanding it's perfectly normal) and incoming & outgoing calls worked fine while mobile data was on...thanks in advance for any thoughts!

It could be your modem but it sounds like you are connecting to a band that for whatever reason doesn't work right on your phone. I have the same phone on AT&T but WiFi calling and VoLTE does not work because it's not an AT&T branded phone. Good luck, sorry I cannot be more help.
@fir3fight3r
Just another thought. Open your dialer, type *#0011# and compare what you see to my screenshot. There will be differences but it could get you going in the right direction.

That is the same screen it is just showing different information.
Below is a screenshot for when I am on 3G.
I would urge you to Google your provider's APN and create a new one with that information.
