[Q] Galaxy tab 10.1 3G does not recognise SIM card - Galaxy Tab 10.1 Q&A, Help & Troubleshooting

Hi there, I have purchased my tab last friday, played around with it during the weekend (root, overclock, etc.) Everything was fine - internet connection via 3G and WiFi, battery life and so on. However after I swithed off my tab on sunday evening and left it on charger, monday morning I realised that galaxy tab 10.1 does not recognise any SIM cards. The device itself is unlocked here, in Lithuania.
Any ideas what might have caused this strange behaviour? Everything else is working fine.

Hi!
I have the same problem, started about a week ago. SIM-card just looses connection at random times. Mostly when i've just left it in the charger for an hour or two.
A reboot is needed then it's working as normal.
What do you think? Should i return it?

Did you try and setup the APN manually?

Obviously...
The thing is that device itself does not recognise SIM card. Once You try to configure APN manually, it sais "please insert SIM card" :-(
and reboot doesnot help...

I have this issue too! I thought i was the only one experiencing this.

I have this problem 1 time, but i tried to switch sim with the one in my phone and it worked. Afther i switched back again and still working.
I got the problem afther my tab have been switch off for 5 days.

Well, after I left device in one of authorised dealers, they acknowledged the problem and offered to replace this Tab. So it turns out, one can only hope, that it does not happen to him...

Hi guys
Turns out all my problems were caused by overclock kernel. Today my tab was replaced so first thing I did was root it again and make a back up. Then I installed OC zip file from SD card via CWM recovery. Guess what? Device did not recognise SIM card again... luckily I had a back up ROM. After I went back to the original ROM everything was OK.
So be careful before over locking your tabs.

my 10.1 tablet says please insert sim card after i have inserted the sim card is it possible..i bought it in hong kong and now am in africa...its kh5
my friends is kg7 and it works fine cud it b a software issue or hardware

same problem just happened to me.
is there any solution found?
sim is ok on my htc desire but tab 10.1 cant detect it.
it has stop suddenly while browsing some news sites.
reboot does not help
i tried with another SIM also, same problem - cant detect SIM card at all,
when trying to open Mobile Network it says - Please insert SIM Card or something simllar.
Also i found that in About Phone - Status, IMEI and IMEI SV are Unknown, Serial is OK, is this normal?

Look I know this is a dumb question, but have you rebooting the tab after inserting the Sim? A client of mine had the same issue and we struggled for days until we realized we hasn't tried that. Sure enough that was the issue.
I think the tab only tries to access the Sim card on bootup.
Sorry if you have already tried this.

Network Reject - HELP please

Hello Problem solvers
I am going to buy an HTC Amaze , but there seems to be a little problem with the network of the phone , below i have stated down the exact lines what the seller has told me. Please suggest should i buy this or not.
The seller says :
"I bought it from someone and everything was unused. I put my sim card in and it worked for a few hours then it was unable to read my sim card. My sim still works on my other smartphone, but I do not have the time to find out what is wrong with the phone. I've tried other sim cards from other phones and also did NOT work. Seems like it won't connect to the network no matter what. Maybe the phone is locked or is not able to be used for whatever reason. Everything on the phone works perfectly as new. WIFI, apps, camera camcorder, games, etc. Everything.. Just doesn't seem like it will get any signal from the service provider. Possibly someone will know what to do and can fix or modify it. Can use it like it is or take it for parts, I don't know. Comes with all original equipment: USB cable/charger, manuals, and will have 8GB micro SD card. AGAIN, THE PHONE IS NOT CONNECTING TO THE NETWORK (SERVICE PROVIDER) AT ALL."

He later adds on to his saying :
UPDATE: Actually, the phone recognizes when a sim card is in, but will not connect to the network to make a call or connect for data. I am almost sure nothing is wrong with the phone and possibly could be a problem with the network or service provider.

Has anyone experienced this before? Please let me know what should i do, The price in which he is giving it to me is very good. If there are any solutions for this problem , please mention.
Thank you forum!
Regards,
Hmmm....the phone is like a month old. It is still under warranty. Why isn't the seller getting it fixed rather than take a loss? I'd be very suspicious. It could have been reported stolen and locked down. My spidey sense is tingling.
My replacement did this, I went into network settings and chose network, search automatically and wala problem solved. But still don't hand over the green until your sure.

Could the IMEI be blacklisted?
You have to call Tmo and have them register your sim. I had same prob when I first got amaze.
Sent from my HTC_Amaze_4G using XDA App
it might also be the sim card ... i know when i bought the amaze from the tmo store they said it will not take the sim from my old phone and that it only works with the sim card that came with the phone...

[Q] Not Registered on Network - How to fix?

Does anybody know how to fix this "error" message or why it shows up? I can't use the phone... as a phone!
I have the same issue. Even when I insert sim It says "no sim". I checked the phone lock status. But It's all unlocked. Please guys help us...........
Yesterday i had this problem too but today morning when i restarted my phone I got my phone registered to network seems like a carrier related issue. Try formatting your phone. And i also noticed that when the sim card was not placed correctly it showed me No sim card( i cut my sim using a scissor). So try placing your sim perfectly or try formatting your phone.

Hole volume up + middle key and switch on your phone. Your phone will get you into recovery mode from that menu using the volume rocker keys select format option and your phone will be hard reseted.

So far so good... my card is also made by me (cut with scissors)... but I have tried a different Micro Sim - factory cut - other number on it and still no change!

I had similar problems when my phone was delivered on Tuesday - cut my (Orange) SIM down to size, it worked for a while, then no network. Took it to an Orange shop, they tried their microSIMs, none worked. Arranged to have the phone replaced, but had another last play, and then my cut SIM in it started working - it would lose service intermittently, but eventually it was, and is, stable.
Mine has intermittent reception issues, ie dropping to emergency only every so often. My phone was sim-free so I figured it was because it lacks vodafone's customization.
I also cut my sim, maybe its an issue of it moving about slightly causing interrupts.

Guys i had the same problem, theres a solution in my thread that i didnt try cause i managed to get the faulty phone replaced but u's should try it and see if it works
http://forum.xda-developers.com/showthread.php?p=27723063#post27723063
It seems that nobody knows exactly what is the fault, the part with the sim cut wrong ( it cannot be )... I have tried 2 different micro sim (factory cut) and still no difference... now I'm using my homemade the micro sim in my Galaxy S2 (without any adapters) and works perfect ( even moved around )... The Galaxy S3 is still not working! After checking with one of the guys from Phones4U, he told me that it can be a fault (hardware or software)... the best way to fix it... is replace the phone! I did not try any of the fixes from here ( so I will not make any changes to the phone - needed for the replacement - warranty )... if anyone has a good fix for this, just post it here for other people who are facing the same problem, thank you!
Your symptoms and what you've tried sounds so similar to what I had on Tuesday, also on Orange.
The guy in the Orange shop suggested to me that you'd see the same symptoms if the IMEI is reported as being lost/stolen - obviously my phone was brand new out of a sealed box, from Amazon, so this was unlikely, but it's an interesting thought if yours was second hand?
Have you managed to connect the phone via Wifi, and perform an update? This is what I did, on the off-chance it might help, as there was an update waiting. My phone did then intermittently connect to the mobile network, and gradually got more stable. It's fine now. Worth a try if you haven't already?
If your SIM card is not recognized, try this

Well, I got this problem too. And I found out that you have to push the card with a sharp object to the far left (when holding the phone with the SIM slot downwards, I shot it from the the opposite angle because of the light) inside the SIM slot for the phone to recognize your own made micro SIM. I used the SIM pin from a iPhone 4S, but I also tried with a needle and scissors, and they all worked fine.
As you can see in the picture, theres a "pin" sticking out the right (when holding the phone as described above the pin will be on the left side) Make sure that the pin "sticks out" as showed in the photo. It seems that if that pin isn't sticking out, the phone will not recognize that a SIM is inserted. I was trying for over an hour, and then I tried this and it worked at the first try.
Good advice, mistwalker, I also wondered if it was anything to do with whether it 'clicks' into position in the slot. Mine works now, so I'm not touching it again!
It has happened twice for me that it says it's not registered on network, both times i've held the power button down and deactivated the network then activated it again and it's been working.

Thank you for the advice, I have tried all so far... even updating the phone, in the last 2 hours I got stuck changing the position of the sim... I tried also a different sim... and same message comes on the screen! I will send it back to the seller and get a refund for it... the "funny" part is that I have moved the "micro sim" from S2 to S3 a few times, and the S2 has never let me down... with no micro sim adapter on it!
I think Galaxy S2 is still one of the best phones on the market... it is not so fragile as S3... and this is my second S3... the first one had to be replaced because a small accident (screen cracked after a bump in the wall)... and the bump was a light one. I admit is faster (like a "rocket"), but the "new" screen - gorilla glass 2 is fragile (like an egg)
Does anyone know how to check if the phone (IMEI) is on the blacklist? Maybe this is the "fault" from my S3... :cyclops:

"No Sim" Error on AT&T Galaxy Note

All of sudden, my phone does not detect the SIM card anymore. I inserted another good SIM card, and get the same error. I tried to press the SIM card to ensure good contact, but not working. No problem with other function. I inspected the SIM card slot and it appears perfect. The phone has never been dropped or having liquid damage.
I did the factory reset, but could not get rid of the error. Unfortunately I just travelled to oversea...
AT&T agreed to replace the phone, but I will not have any phone on the road.
I am willing to try anything. Does not seem to be software related, but...
Anyone know how to fix the problem?
Thanks.
Hey. There us a thread about this just search for it... don't think they found a solution
Did this happen while your sim was still in the phone or after a removal and replace?

My 1717D stpped working too when I installed T-Mobile radio
I bought 1717D with Android 4.o.4 on it , Kernel 3.0.8-perf-1717DTLLF4-CL793911 and tryed to install T-Mobile modem to work with Mobilicity.Ufter this update phone doesnt recognize my SIM card any more.I Tryed all 3 modems with the same results, even though I did changed modem on two previous 1717 phones before.They were with 3.3.5. I thing The problem is in Gingrbred rom this pfone has.Where can I get original Yelus factory Rom ?One more thing is strange: it doesn't show any IMEI ,Baseband shows Unknown.
The phone has ics 4.0.4. I inserted a foreign sim card while traveling abroad and found "no sim" error. Then i switched back to the att sim and found with the same error. I shall say i always use the foreign sim while oversea and never had problem with this phone before. And i always power down, remove battery and then replace sim card.
I reflashed the ics radio and still no good. I can see the imei number in setting. But the baseband is unknown. I read almost all related posts and could not find a software fix.

"No SIM" just happened to me. I recently updated to the official JB stock ROM & Note worked great for about ten days... then just quit and displayed the "No SIM" error message. I first tried just shutting down, removing & cleaning SIM, replacing & rebooting. Nada. Then tried different, fully charged battery. Still no go. Still at home tried a factory reset, removing SIM, clean, & reboot. Gave up and went to an AT&T kiosk. Rep set me up with a new SIM and I'm back in business for two days now. Rep was quite philosophical, "it happens sometime." Still don't know why.

Same thing happened to me a couple weeks ago, now it wont read the sim at all. I ordered a new sim tray but it has not arrived yet, but if you search other threads, this may not fix our issue. Seems to be a problem with this phone.. I'll keep you posted if the replacement fixes my issue.
Dunno. Might be a fault in the mobo or the sim slot. I replaced the sim slot and it went away for the most part, but it comes back at least once per day.
