A problem with sim card after official at&t 4.0.4 upgrade - AT&T Samsung Galaxy S II Skyrocket SGH-I727

I bought an unlocked skyrocket yesterday and then tried to reflash the stock 4.0.4 rom on it. After that, the phone seems to be unable to recognize the sim card, and the carrier's label is gone sometimes. Now I can still make calls and send sms sometimes, but i can't most of the time. Can anyone tell me if it's the problem with the phone unlocking process or something involved with the rom I'd just upgrade?

what network you're on and SIM ? try replacing the SIM first of possible

i'm using a sim from a Vietnamese mobile network. I bought this phone for my mom, and last night it was unable to regconize her sim. I also try it on my wife's and my dad's, and they were all unrecognized. I turned it off and retry this morning, and it 's working like nothing happened before =.=. I just dont know if it's gonna be in that situation again

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.

com.android.phone error

i have 2 phones one i us most of the time one is for drunk nights out etc bc i dont want my other one to get lost damanged stolen.
the 2nd phone is lg optimus black p970.
its been working 100% fine.
i havent used it for about a week.
tongiht i go to use it and keep gettin the com.adroid.phone error.
i have NO IDEA why.
i havent updated anything new (apps) i have updated the software or anything.
a week ago i powered it off and it had been working fine. all i did tonight was power it on, went to send a text and it gives me that error. the same with whatapp. dl'ing apps works.
any idea what it could be & why its happened? how to fix?
the phone is NOT rooted its entirely stock standard. (i dont want to root either.)
i'm on O2.
tried the phone with another sim (also o2) and it works fine.
but i dont understand because i have used the phone with my usual o2 sim card before like 1 week ago.
powered the phone off with that sim inside. used the sim in another phone for 1 week now put it back in lg and power on and get that error.
just a bump.
i was given a new sim card from my network provider but the error still exists.
i've done a factory reset of the phone and its still getting the same error.
COM.ANDROID.PHONE
i dont understand why its only that sim card. the sim works fine in my other 2 phone but on the other hand every other sim i've tried (a different o2 one,t-mobile & orange) all work in the phone that gives me the error with my usual sim.
i cant determine is it the phone or the sim. the sim works wiht other phones, the phone works with other sims :$
could it be my phone number causing the problem.

Galaxy Mega SIM Problem

I have a sgh-i527m (Bell) which got unlocked. I tried a few custom roms but went back to this stock rom since I wanted full functionability.
Periodically, I would get the "no sim card" error. A simple reboot or re-insertion of the sim card usually fixed this issue but earlier today, It just clunked randomly and no matter what I tried, I could not get my sim to work (Fido). I even went to Fido and got a new SIM, since my sim was so old it wasn't even the LTE sim. And still no luck.
I even tried using the scotch tape Nexus fix, still nothing.
I tried re-flashing stock rom, no luck. Going to try a nandroid backup.
Also, my friend's SIM works fine, which is Rogers but my Fido sim won't work yet my Sim works fine in his phone (unlocked i9500). Ironic, because Fido uses the Rogers network..it makes no sense.
Somebody shed some light please?

[Q] Missing network operator

I'm not sure if this is a network issue or a phone issue. I just got a replacement phone from Google. Popped in my sim 2 days ago and it was working fine, OTA 4.4.4 updated the same day. Came to work today and it was working for about an hour, and now it says there is no connection. I go to the "network operators" list and I only see ATT on there, which doesn't work for me since I'm on T-mobile. Other people in my building have T-mobile too and their phones work just fine, so I'm guessing it's not a tower issue.
I've tried restarting the phone as well as taking the sim out and reinserting it. Anything else I can try?
Phone is stock, not rooted, not flashed with a new rom.

SIM inserted but no service?

Hi all. I have been using this 920I Singapore (bought fr starhub but on singtel network) for abt 2 mths already with everything working fine until abt a week ago. The SIM would become undetected forcing me to restart the phone. I repeated the process multiple times until today, when the phone no longer detects the SIM card, rendering the phone unable to call n text
What could be causing this? Anyone with similar problems and/or fixes? Thanks
Try a new SIM? Could be faulty...
Defective SIM most likely.
