[q] no sim issue - AT&T Samsung Galaxy S II Skyrocket SGH-I727

Having a huge issue here need some help, I recently finally got my unlock code from ATT and was very happy, I applied my unlock code with a SIM I had at work and all was good, I will be traveling out of country and had an Ekit SIM decided to test with the phone, it worked fine, then I went to put in my ATT SIM (i had it cut for microsim size, so I`m using adapter, but never had issues) and now I get the little no SIM sign and no service, interesting part is that the signal bars seemed to go up maybe just cosmetic...
I was on the ICS and then went back to SkyICS which is 2.3.5 but my modem statyed on UCLA4, I found the older 3 modem and now it shows no bars but still SIM is not working, I tried multiple SIM cards and always show the SIM symbols and when I go to mobile networks it says SIM is not present. Please help me as this is my primary phone and Im stuck, I really wouldnt like to reset everything.

If it was me I'd make a nandroid backup, then ODIN flash the Samsung official stock I727 UCKJ2 2.3.5 firmware from sammobile here. After flashing stock, booted into stock e3 recovery and do a wipe data/factory reset and see if that resolves the 'no sim' issue. If the phone still doesn't recognize the AT&T sim, take it into an AT&T store and request a new sim card. If it's still borked even with a new sim card they should swap it under warranty.

I guess I have to try to go to Stock, no choice here, I know its not the SIM tried in wifes phone and its fine, also that EKit SIM that just worked in the phone does not, could I some how damaged the SIM card holder ?

Sounds like it could be the sim slot. Anyway, if you put it back to stock you'll have not issues at the store when you swap it. Then restore your nandroid backup on the new phone.

Only thing is I bought this phone on ebay back in January, its registered under my account and everything, and I got it brand new. I hope ATT will repair/replace under warranty. Sad thing is I was fighting with ATT for 2 weeks to get this phone unlocked and finally got it now I have to swap it and go thru the same process .
I dont get how this happened, this is not the first time I swap SIMs and all was good, I think its pretty hard to break a SIM slot, but I guess I did it some how. So Pissed off right now its not even funny

Just as a long shot, maybe try cleaning the sim card contacts with a pink pencil eraser. Sounds crazy, but I have a Garmin running watch and the contacts on the back sometimes get dirty and it won't sync with my PC, so I just 'erase' them a bit and it's back in action.
If AT&T won't do the warranty swap, Samsung will directly-- although that's a little more of a hassle. Good luck!

The card and the slot contacts, if you can get at them.
Also, you said the card is cut and in an adapter - maybe it's just not quite lining up with the slot pins. Try it with the card not quite fully pushed into the slot.

I cant even backup current ROM, it gets to somewhere on the data part and trows me back to recovery, been doing this for the last hour, getting really frustrated and tired !

Maybe it's time to punt and flash stock 2.3.5 with factory reset.

Yep was able to backup and flash stock from here http://forum.xda-developers.com/showthread.php?t=1342348. still same no sim, I cleaned the SIM and the slot, even tried with some compressed air nothing all the same... I guess I`ll go to ATT store, do they usually replace phones on the spot ? I`m used to going to apple store where they just replace it... This really sucks !

I don't know if this will help, but have you tried manually inputting the APN for whatever carrier SIM you have at the moment? It's worth a shot
Edit: and are they LTE SIMS?

G2X won't recognize SIM card

Anyone else experience issues with swapping their SIM from their old phone into the G2X? I have reseated mine from my N1 into the phone 3 times, and each time I boot it says I have no SIM card. Pulling my hair out!
I went from an N1 to the g2x and i had the same problem so here is the deal...
the g2x is a 4g phone and it required a new sim card version so i had to trade in the sim card that i have had since my i got my razr in 2005...
so disclaimer to anyone who buys the phone outright, you have to have an updated sim card... just go into tmobile and they will give you one...
mines wont check for sim card at all it keep saying no service even without a sim card it usually say no sim but it just say no service can someone help plz plz plz
Fyi make sure it is a corporate store. Otherwise it could cost ya $20. Customer care might even be able to mail you one...not sure. If your near Chicago I would just give you one of my extras.

I reused the sim from my N1 and have had no issues but it was probably a newer version sim since I just got it beginning of last year.
If you have an old T-Mobile phone lying around, try inserting your SIM into that, and using it, then re-insert it into your G2X.
Alright I opened it up and it looked like the antenna cable was a bit frayed near the tip, I attached a few pics. It was connected though so not sure :/

I have the same issue.
Mint condition G2X does not detect my sim card reads "error while trying to connect to network"
I am running CM 7.2 I have wiped everything and reflashed still no luck.
Add one more to the pile...
I also recently began having this problem, but my device previously worked fine.
I have tried Restoring to Factory V21Y with Mar 11 Baseband
Flasing a GB Based ROM & Stock Kernel
Flashing CM9
Flashing CM10
Entering *#*#INFO#*#* Phone Info and modifying frequency band (No Go).
At one point I was able to read the Phone # from the SIM card, but couldn't get a lock on Netowkr. I can visually detect T-Mobile and ATT in Mobile Networks.
I have tried this with 4G Enabled SIM Cards and older T-Mobile SIM Cards.
I have tried Simple Mobile, Straight Talk, & ATT SIM Cards.
I have tried using None APN's, the TMo/Simple Default APN's, and Modified APN's for Straight Talk & Family Talk.
No avail.
Any ideas?
I had the same problem. A new SIM card fixed it.

I gave my friend my old G2x because she was switching from AT&T to TMobile. She went to the TMobile store and got a new SIM card and her old AT&T number transferred to it. It works on her old iPhone but when I insert the SIM card on the LG G2x , it keeps saying 'no SIM card inserted'....do i need to flash a certain baseband on it and/or setup a custom APN for it? I am on the stock ROM thats rooted...
Any help is much appreciateed
Sorry for not replying until now but I rarely visit here anymore. My G2X had a bad Sim card which a new Sim fixed. I just had to wait until the network could authorize with it.

Lost Cell Service

I was changing my V6 Supercharger settings yesterday when I noticed my cell service crap out. I thought it was due to me changing from build.prop to local.prop, but changing the setting back did not resolve the issue. So, I unSupercharged.. nothing. Wiped data, cache, dalvik and reinstalled Tweakstockv1.1.. nothing (via CWR). Odin'd Tweakstockv1.. nothing. Odin'd Tweakstockv1.1... nothing (left battery and SIM in while Odin'ing, like I usually do).
I tried pulling the battery and SIM card but that didn't help. I checked my Verizon account - it's active.
What in the fudgeballs just happened? Does it sound like a fried SIM?
I just Odin'd Tweakstockv1 for ****s and gigs WITHOUT the battery and SIM card installed... No cell service, but mobile data came back.
What in the balllllllls?
Flash it back to stock and bring it to Verizon store.
It may just be a bad SIM card. Take the card into the store and they should replace it for free. May want to flash back stock as recommended above prior to your visit.

You might be right with the bad sim card idea. Its always been recommended to Odin without sim card in phone.

Can I use a coworker's SIM card to test? Or do I need a brand new one from Verizon? I'm thinking I can use another SIM card since Verizon activates via the device's IMEI?

wont work like that with Verizon. Your co-worker with have to unregister their device with that sim. Than you would have to register that sim to your phone. More hassel than your co-worker is going to want to deal with.

What on earth are you talking about? You can switch sims through 4G phones just fine. I have a Revolution and also a Charge, I can swap between them just fine. The Charge was on brothers line, but I just installed my sim and everything worked prefect

Hello, I purchased a galaxy tab 7 plus in Hong Kong. All work great until 2 days ago,

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.
Sent from my GT-I9100 using XDA
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...

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

No sim card error?? Any solutions??

This is not my forum, I don't have one yet, I have the bell, samsung galaxy s2 hd lte. It's a brand new device 9 days old, it started yesterday saying "no sim card inserted " I had you pull the battery and sim card then reboot, it was fine again for 12 hours now it's happened twice?? Anyone else experienced this??
Our phones are similar, bell said get a new sim, which I will tomorrow, however after a Google search this seems to be a popular error with the s2.

Are you on the stock ROM? Are you rooted? Did you flash anything to the phone or change the ROM, Kernel, or modem? If you haven't done any of this, I would try the new SIM card. If that doesn't work, exchange the phone. If you have done something, try going back to stock and see if it resolves the issue. Alot of times it comes down to the modem / radio being mismatched to a ROM or Kernel.
im having the same problem, the way to fix it is odin flash the firmware from sammobile, buttt i cant connect my phone via usb anymore thus im stuck with this problem ;(
2 Possible Solutions(Easy Fix)
1, wait out the data outage in your area. We are on ATT and having the same exact issue and when I called 611(Customer Service) the automated answering system told me that they are currently experiencing data outages in my area. could be due to a tower/service upgrade being that 4G is coming out in more areas now.
2, call 611 and set up your phone model with the customer service rep at the technical support extension.
I would put a 3rd option... but I haven't tried flashing a new rom yet, I just got the Skyrocket as a free refurb from Insurance and I am currently on an unrooted stock GB ROM.
yes flashing to original rogers tar using odin did fix it.. but if i try other roms its broken again, so for now it looks like ill have to stay with the original firmware
If you flash the ucle2 modem in SeanZscreams post it will most likely fix the issue on each Rom you flash as long as you flash the modem after.

To check to see if its your SIM card, use a USB Adapter or microSD -> SD adapter. Back up all your files then reformat it using: https://www.sdcard.org/downloads/formatter_3/ and then put back all your stuff and try again.
try this or other plp that have this problem try this pliz an coment

The error message that said I needed to insert a valid sim card happened again today while traveling home.
The good news is I think I figured it out!
The Galaxy S4 requires a "nfc" enabled sim card!
You can't tell by looking at the tiny sim but the larger card the sim comes in has a notation of "nfc" if it's the right card.
I hung out in the Verizon store after inserting it and the drove home "an hour drive" and absolutely no errors!
And I maintained a 4g signal throughout my whole trip which was through some back country where signal is usually marginal.
This is a pretty serious problem for Verizon.
Why?
1. Because if I would have ran around in safe mode it still would have errored.
2. If I would have reformatted to factory settings... The same... All for nothing and days of configuration lost.
3. If I got another new phone, again the same.... All because I would be using my same sim card.!
I'm sure many replace the whole phone "and" sim together and when it works it's assumed the problem was the phone or software.
What a terrible headache for the customer, tech support, and verizon customer service just because people don't know the proper sim card needed for the S4!

T-Mobile not working with OPO

Hey everyone thanks for your help in advance... I just bought my phone and went to T-Mobile to get a new micro Sims card. After putting it in, the phone didn't recognize it. I put in the APN settings and it doesn't save it. This really sucks right now because I don't know what else to do. Any help will be greatly appreciated. And my phone isnt rooted yet, just want the stock for now. Thanks again
Is the sim activated? Sometimes on a new sim it takes a few hours to start working.
I was already on Tmo with an N5. I just moved the sim over and all was good.

Also did u insert the sim properly into its slot?

I screwed up and instead of using my old Sim card and cutting I went into T-Mobile and had them activate a new micro Sim card and put it straight in. The old one is deactivated.
The new micro Sim does work in my old gslaxy S2 phone which used an older big Sim card. Its now using a Sim adapter.

Did you insert the SIM card in the right direction and not upside down? I know thats silly to ask.
to be honest its simple man and actually nothing you needed to make a thread about. Simple go to TMobile store and try an already active sim card. Go to AT&T and see if they can put an active sim card to help you out. Basically go to anywhere that works with a TMobile or AT&T derivative and try it out. Nothing really else we can do to help you on this.
Not try to be rude or anything but its the truth. If none of that works then you may have to RMA. Also maybe find a friend or family member and try their sim . Good luck :good:
Should work. Using my one plus with Solavei (t-mobile based company) and having no issues.

First time i've also put the tray wrong. True story
Just had this problem after coming from using the phone overseas and no signal whatsoever on the phone despite numerous restarts, SIM cleaning, and chats with T mobile. After verifying the APN was correct I went to Settings-->About Phone-->Status-->SIM Status and checked to see if the SIM was connected(it showed my phone number, but was disconnected). So from here went to Settings-->Mobile Networks-->Network Operators and let the phone find carriers automatically. Mine showed T-mobile(with a little SIM icon to the right of it), Verizon, and ATT. I clicked on T-Mobile and it registered and is now working.
Probably saved me $15 at the T-Mobile store. Hope this helps even just one of you.
