Hello, I purchased a galaxy tab 7 plus in Hong Kong. All work great until 2 days ago, I inserted another Sim card then it now says no Sim card. I tried with several other Sim cards but no luck, I did a factory reset, flashed with firmware from Sam mobile but still no luck, I don't know what else to do before I send it to Samsung for repair that gonna be expensive, help is greatly wanted, thank you.

Try to insert the sim card with the tablet on. Does it restart? If not are you sure you are inserting it with the correct side?
Hello, thanks for the answer, I tried all that already, anyway the Sim only fit in one position so you cannot take wrong.
The tab restarts when inserting card yes.
I tried also taking the battery out for 10 mins... Clean the head of the Sim compartment but no luck.

Just removed the back by pushing under the sd card slot then inserted a flat tool to unclip the lid, then removed the batery connector.
However i still have the issue, its driving me crazy as it is my working tool...
does the original SIM still work in it?
perhaps try flashing original & latest frimware updates for new/different modem.
I know one chinese version of tab plus has locked bootloaded dud to China's restrictions, I would not be surprised if they have locked down modem as well.
And for the heck of it you could always try Galaxy S Unlock app, to be certain you're unlocked.
Strongly suggest backing up /EFS folder (twice) just in case.
Thanks for the suggestion, I flashed the device twice already but there is only one file. Could you direct me to the files you are referring to please I'll take a look when I'm back home, thanks again.

I would try EVERYTHING else before flashing a new modem. Toggle airplane mode. disable/enable packet data, etc.
First, does the original SIM still work?
If so I would give the Galaxy S Unlock a shot for the heck of it.
These other SIMs have you tried them in other devices to either make sure they work or activate them?
did you purchase device on a SIM contract??
sim issue
The original sim does work, i have put it in other phones and it works fine, i have also tried other sim but still same issue, message still say "please insert sim card"
I have purchased the tab sim free in hk so no, no contract, it did work fine since december until 2 days ago where i input a data only sim card, when i insert sim card it does reboot, meaning it detects the card in the socket but thats it.
Concerning Galaxy S Unlock my tab is not rooted i have used only legit firmware until now so im not sure about that.
PS: looking at my phone servie status it says:
Service State: Out of service
Are you sure you havent been sold a bad or expired sim card?
Id try to give samsung customer support a call at least, they will probably tell you to send it to them anyway.
Can you try exchanging this for another one where you puchased it?
Well, i bought it during my holidays in hk but i live in norway, so... bit difficult to chage it, the sim card works just fine in other devices so it should work in tab.
I tried the galaxy s unlock and during step 1 it says error for efs backup, so either because im not rooted or because my efs is corrupted.
Probably because youre not rooted.
Im wondering if the SIM could be from a small provider which isnt recognized by the device?
It should at least dected then say something like network provider unrecognized, etc.
I really dont what to say.
I would keep trying other sims, try to get a 5$ pre pay from a major carrier like O2, 3, tmobile, etc. not sure what carriers you have over there.
Well i use Telenor which is the biggest and also quite big in europe, i will call customer service tomorrow and hear what they say, but i fear its gonna rip my pockets...

did you push the simcard all the way to the bottom of the slot?
I need a pen to push it....so I wonder if you insert your sim card properly.

yes, since the first time, repair shop said they cannot help since device has been purchased in hong kong...
No solutions until today...
Solved
After dismantling the tab completely (hard work guys...) i confirm that the sim card reader is defect, the cushions that reads the card did not press completely on it so i applied a temporary fix by adding an extra layer to thicken the card so it can press correctly on the cushions. I did try this fix before with the tablet in one piece, however i could not get it to work correctly.
Anyway thanks for your help and i'm happy that i can use it again
i have problem with my nexus s ii cant get in my carrier network im promoted to write my pin code but when im writing it and press ok the phone cant find nothing stuck with no singal what should i do
i think is general problem i tried my sim card on another device the same and my friends father doesnt have singal on the samsung galaxy 3 in the mornig before leave to the job show its general problem
Have you done anything to your phone since the last time it worked? Any updates? Did you flash your rom/radio? If you tested it on someone else's phone and it didn't work there either I'd say it's your sim card. Try in a 3rd phone just to be sure, but I'd consider taking it to your Cell provider to get the sim card checked out.
Call your carrier.

Which is why you shouldn't purchase a non compatible phone, for use in another area?
This is why you shouldn't buy this phone from the scalpers. The chinese version does not support many of the worldwide bands that the "global" version of the phone does. My advice would be to try to sell it to someone who can use it and sign up on the OnePlus forums and wait for an invite for the CM version which supports the bands you need.
Get a new sim, sounds like an old sim that doesn't have the updated CellID info in it.
I had to change my 3 sim when I had my SGS4 as it wouldn't register because it was too old.

I had that happen to me on the interational one and felt quite dumb afterwards...
Make sure the SIM card tray is rotated DOWN so that the contacts on the sim card look to the back of the phone.
It will fit both ways (imho a very strange design choice) but with a tiny little space left when rotated the wrong way.
In other words: turn the phone on it's screen before inserting the sim card facing you.
I have _NO_ clue why the phone thinks it has a SIM card when obviously it cannot access it...

Hi ,
I recently bought Vodafone Smart Ultra 6, which is obviously locked to Vodafone. I did all the start-up settings and everything was running fine. Since my actual network carrier was EE ( Orange ) I unlocked the phone, which worked alright up until the point where it suddenly the phone would lose reception and regain it at random times. I thought that since my sim was really old and cut with a template to fit the nano sim requirement, I messed something up. I didn't mind swapping carriers since I wasn't that happy with my tarrif, so I ordered GiffGaff sim, got my PAC number from EE and activated my new GiffGaff sim with my old number.
I know for a fact that the sim works, because I tried it on different device, but my phone acts like it's locked to EE after the unlocking I did from vodafone. Every sim card I insert is unrecognisable by the phone, except the old EE card which is no longer active.
I tried doing factory restore, which didn't do anything.
Dialing *#*#4636#*#* and turning the radio on and off -> still nothing
I have no other idea what to do and I can't find any solution on the internet.
My android is 5.1.1 which I read that has similar problems on different devices, but none of the solutions I found worked for me.
Any help will be much appreciated.
I am sorry if the post is confusing and doesn't make much sense :/
To summarise:
The phone was locked to Vodafone and Unlocked immediately with an EE card inside
Now the phone constantly shows NO SIM CARD - Emergency Calls Only ( tried on GiffGaff and Vodafone Sim )
No Network Connection - Can't connect ( tried on EE Orange after initially unlocking, the sim is no longer active)
Thanks in advance!

Hello guys!
I love this phone, but i am having problems getting it to function properly here in Sweden. It was originally bought on a contract and simlocked to Tre (carrier). I bought the phone second hand from swedish ebay (much cheaper than brand new) with the intention of unlocking it and using with my carrier (Telenor).
Tre would not unlock the phone for me (have to see out 24 month contract) so i unlocked it myself using the services of unlockscope.com. The process was successful, and the phone no longer asks for a network unlock code when using previously locked sim.
The problems start now.. It just refuses to register on the network! If i switch the phone off, insert sim and start, then i get a brief flash of the carrier name in top left corner (2 seconds), and then it goes back to saying emergency calls only.
I cannot register manually, i have tried hundreds of times, even though the carrier appears in the list. The apn settings are also correct for my carrier.
I have also contacted my carrier and they dont understand the problem. I even had them run a check on the imei to see if it was blocked on their network (possible stolen phone) but it came back negative, no blocking whatsoever!
The weirdest thing is that it works when using my brothers Tele2 sim card! The phone registers in seconds and displays a nice 4g symbol next to the signal indicator! A thing to note is that this Tele2 nano sim fits very nicely in the tray and stays in place, whereas my telenor sim is extremely loose and falls out, though i have tried taping my sim in place with no success.
Can anybody relate to this problem or think of a possible cause? I dont know what to try anymore! I'm thinking that there must be something wrong with the phone, but then why does Tele2 work perfectly??!!
Sorry for the long post! I appreciate any help offered!

Hi
This is getting weird , did you try to do a factory reset from recovery also wipe cache and if that do not work you could also try to flash the firmware of the phone again ( odin)
http://forum.xda-developers.com/galaxy-s7/how-to/official-stock-firmware-update-odin-t3369431
Just in case is some odd firmware problem , back up everything important first...just in case

I have already tried flashing with stock swedish firmware using odin (G930FXXU1APEQ_G930FVDS1APF1_VDS) but same problem persists.. One weird thing to note though is that even though i do a clean flash with unbranded swedish rom, the phone installs some carrier specific apps from the original carrier the phone was simlocked to upon first boot. How can that be??
Maybe its worth trying an international version?
Thanks for the suggestions

That is odd , yes try a totally different rom just to see how it turns out , even from another country it should not make any difference for the phone and connect easily to a network.

EFS is a very important partition , is where the modem information is.......maybe?

I will try with an international firmware and see if there is any difference.. if not i will follow that guide on efs partition in case that is corrupt.. This is so frustrating!!!
Is it at all possible that a very loose fitting sim could be the problem? As the simcard of the carrier that works fits very snugly in the sim tray.

I have now found out that the phone is stolen!!! So that explains everything. I dont know why the carrier couldnt see that the first time they checked, would have saved me days of frustration!!
It has been reported to the police here in sweden, so hopefully they will find who is responsible and i can get my money back!
Thanks for the help guys, very much appreciated even though it was an impossible case to crack!

Oh no. Have the police found out the thieves? I think my phone may be stolen too because I have the exact same problem.
