I wanted to test the unlock i did on my phone yesterday, so i put my brothers tmobile sim card in my phone, but all it did was show a sim card icon at the top of the status bar, and i didn't have signal. so i just figured the unlock didn't work.
Then when my brother put his sim card back in his phone, his wasn't working. apparently the sim was reformatted or something, and now he has to get a new sim. anyone heard of this before? also should i try another sim card, or will it just destroy that one too?

you forgot to select network operators in the wireless settings. in the wireless and network setting select mobile network then select network operators your phone will then scan available network operators and show you at&t or t-mobile after the scan. since you want t-mobile simply select it.

would that have made his sim card work again if my phone recognized the network? or was that just something weird that happened. I am new to the whole unlocking deal.
Thanks for the help, I am a little nervous to try it now, as i dont want to mess up his card again! :/
you should be fine. is your contact actually stored on your sim? ,maybe your brother's sim is empty but his contacts are stored in his phone. contacts stored in sim card are not easily get deleted than contacts stored in phone simply import you phone contacts to your sim to be safe.
my contacts are fine, but his phone actually would not work when he put his sim card back in his phone. it's just a regular dumbphone, but he didn't have signal or anything. Do you know what would cause that?
there must be an option somewhere in his phone to select the wireless network he has. what phone he is using? maybe a simple reboot on his phone with his sim card already in place would do.
yea maybe, i think he was going to go to tmobile this morning.. i guess i can't really call him to have him try though!
anyway i'll see if he will be brave enough to let me try again! thanks for the help!
I may understand sim cards wrong but from what I understand the sim does not announce to the carrier hey this is eric shins phone. It instead just broad casts a number the carrier sees the number and associates it with eric shins number. That's why you can buy a prepaid att phone call the company up, give them the sim number and they can connect that with your phone.
More then likely the sim was physically damaged

hmm.. that does make sense. I thought i had heard of other people just popping in other people's sim cards and it wasn't a problem, but i don't know.
Just kinda strange that it was working before , and after i tried it, his phone no longer worked. Maybe it was damaged when he took it out or put it in, but from my experience they are pretty sturdy pieces of plastic!
i'll have to see what he says when he gets it fixed.

hmnn... thats what I thought because the op post that somewhere in the process when putting back in the sim he see's it was reformatted. just like putting an sd card with my other phone that is not samsung it can't read/open files unless you format it that would surely delete the data in it. in his instance without a warning it automatically formatted the sim and deleted all the data in it which would make it useless. in his case the sim card before is associated with the network but somehow reformatted and the data in it was lost.
so he went to tmobile today and got a new sim card, and everything works again.
maybe it did get damaged in the process.. who knows now!
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.
Alright, lately after I unlock my phone it tells me that my sim card is not found. It bugs me a lot because I have to shut the phone down and take the card out and back in. No, I didnt drop it and it isnt rooted. Is it my sim card or the phone? And if it keeps doing this, should I send it into ATT?
if you have some compressed air i'd blow it in the sim card slot, but thats probably not the problem i would take it to AT&T and try to get a new sim card or have them look at your phone
Is the sd/sim cover flush?

Is it the SD card that came with the phone, or one you bought separately?

I had to go get a new SIM card today because the original was not connecting. It initially didn't enable a network signal, so the gal rebooted my phone....and of course saw my custom boot animation and status icons and what not...I don't think she had seen a rooted phone before...said something about "you've really bling'd this thing out haven't you? This is the most customized phone I have ever seen"... [sheepish grin]
Pull out the batery and turn on with the sim card inside.

Try the battery pull mentioned above. If it keeps happening then try getting a new sim from att. If the issue persist then call att they will more then likely replace the phone.

Oops. I thought he said SD card. No wonder no one answered that question of mine. Lol
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?

I would do that, but when I go to mobile networks I can't get to setting, it's says Insert sim to change mobile network settings.
The SIMs worked fine before yesterday. 1 is ATT lte 1 is not, but again it says no sim inserted.
Baseband says kj2?

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.

What he said. If OP has another phone that uses a MicroSIM, put the sim in that phone and see if it works.
Also did u insert the sim properly into its slot?

I actually didn't. I agreeing with what you said and added onto your point.
I didn't mean the u to be directed to NaterTots but to the OP. Sorry for the confusion.
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.
