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.

I have just unlocked my tilt with Kaiser SimUnlocker. I put my T-Mobile sim card but no connection. Always searching... I put my friends Cingular sim card (old at&t) and still no connection. So I thought my phone was broken so I took it to local AT&T store and one of the rep says 'maybe it's the sim card'. And he grabs one of his new AT&T sim card and voila! connected. Have anyone had that problem? What can I do to fix this? My T-Mobile sim card is says 38.01e on the card next to my sim serial number. Is it my sim card? Do I have to get a new sim card? I've just got this sim card about 2 months ago. Any suggestion?
I assume you reflashed an appropriate radio after unlocking?
I would try flashing a new radio anyway to see if that sorts your problem.
I've tried severa different radio roms with no luck. Right now I've reflashed back to US At&T rom. I still no clue why my T-Mobile sim will not connect to the network...
On AT&T, the tilt requires the newer AT&T 3G cards - thus probably why the Cingular card didn't work. Are you sure the SIM unlock process worked for you? If your T-mobile SIM is that new, I can't imagine you needing a new T-Mobile SIM. The T-Mobile SIM has worked in another phone?

That's strange b/c my Cingular card works on my tilt.
I unlocked my AT&T Tilt and then put in my (almost 1 year old) t-mobile sim card and it worked immediately without any problems. I used the original radio as directed in the unlocking tutorial. So it sounds like maybe you should do the unlocking procedure again. ?
Hope this helps,

did you even try putting ur sim into another phone and see if it works? just making sure u covered everything here
Maybe you are locked into 3G
Go under Phone/Options/Band and make sure the top is either set to Auto or GSM
Thanks for all the replys...
I have tried just about everything...
I know it's unlock b/c it does not ask for unlock code no more. I have hp hw6945 that is also unlocked and works perfect in there. It connects almost instantly so I know my sim card works too. Also tried changing band setting to Auto and 900/1800 and everything and no luck... Going crazy and frustrated... about to just sell it to some at&t user and buy a new one, try again.
Just to let you xda'ers know that when I tried to unlock it for the first time I tried with spl-1.56 on it as a factory (dummy me) then tried SuperCid unlock which changed to spl-1.0 then proceded with rest of the unlock. Maybe that messed something up?
I've had that issue but my sim card with t-mobile was 4 years old. Had to purchase a new sim card and everything worked fine after that. With my old sim card, the tilt wouldn't even recognize the card.
Anybody want to donate an old T-Mobile SIM to me
buddy had same issue just happen.. he had to go to tmobile and show them the sim wasnt working they gave him a new @ no charge
I had a old cingular card that came with my Razr and it worked fine in my 8525 Hermes, but it said no service in my 8925 tilt. I would try a new t-mobile card.
Well I recently purchased a G2x and I wanted to use the phone on the Simple Mobile Network, but when I put the sim card in and power on the phone it states "Invalid Sim Card" now when I contacted LG about this their tech support stated that I need a new sim card, but that makes no sense because the sim card works on other phones so as you can see I'm at a loss as what to do or what could be wrong. I've included what it shows as far as the system information that I see. Also I should mention that the phone starts up fine, but it never requests an unlock code??

Are you sure that it works with other carriers than T-mobile? If you are sure, replace your SIM card.
I have no problem with simple mobile, try a new sim

Did you unlock the device? It may need to be unlocked for your Simple Mobile SIM...
The phone has been unlocked and the crazy part is that I put a brand new sim card in it and it still would come up as no sim card. So I'm at at a loss now because the only sim that seemed to respond was tmobile, but the ones I used from simple mobile would not be read.
Go to the Dev section and look at CWM. Make your phone bullet proof first.
Then in CWM wipe everything but the SD card. If you need help let us know. Download a rom (I use weapon) using your computer. Place it on your SD card. Load CWM. Select install zip. Select the rom on your SD card. Let it install then wait 10 minutes reboot wait five minutes then log on and enjoy.
Also look at the wind united post. It may help.
Make sure you are inserting the sim fully and it is making contact. Also sometimes it does that and reboot fixes it.
Thank you all for the info and help. I really would like to avoid having to root the phone.. I did find out though from LG that apparently these phones are having problems with the IMEI number... A representative stated to me that if the phone says "Invalid Sim" then you must contact T-Mobile so they can unlock the IMEI number, but in my case it is saying that there is "No Sim Card" I've used At&t, T-Mobile and Simple Mobile sims and it still says "No Sim Card" which leads me to believe that it is a hardware issue and I'm actually sending it in for repair....
So for any of you who get the "Invalid Sim" dont bother calling LG cause they will basically give you the shaft and send you back to T-Mobile to get the problem resolved...
Hmm......sometimes I put my sim card the wrong way which gave me invalid sim card msg..... so just double check that the cut off edge is on the right side.
Also, if your phone is indeed unlocked, try unlocking it again it would not hurt.
I would also check the radio frequencies capabilities for your phone because simple network might not support that. For example, I use wind network in canada, which uses the radio frequency equivalent of 1700, which is also compatible to t-mobile g2x.
Hope this helps.
You said it has worked with a T-mobile sim card? Are you sure? Borrow someone's sim card for a few minutes (one that has an account on it) and see if it works.
If it does than it sounds like the phone is actually locked.
If it doesn't than the phone is the problem. It's either on the wrong baseband (not 1700) or it's a hardware problem.
Honestly, even a locked T-mobile phone should work with Simple Mobile. I have set up 2 locked phones with them already (one G2x today, and one older phone) with sim cards from ebay.
So the final question is, did you buy a Simple Mobile "activation kit" or just a replacement sim card? You need a NEW, unopened sim card kit. Ebay could have sold you a previously owned one.
Hope this helps.

One more thing. If an active T-mobile card works in it you could try forcing the APN settings to Simple Mobile.
Root your phone (it's easy I promise!) There is also an unroot application you can install if you're worried. Look in the market.
Then install an app in the market called APN Manager. Delete the T-mobile APN listing. (write the t-mobile settings down so you'll be able to add it again if necessary.)
If all of this is too much for you, seriously just exchange the phone and start over. But MAKER SURE the new phone is for a USA 1700 cell phone service!

Umm......the G2x is P999.....this is the right forum section. And that forum link is to this forum section....
Also, I should add that you should be on stock ROM if your using this phone on a different carrier. The unlock menue doesn't show up on CM7....unless they've changed something int he past couple months.
Well I've sent in the phone for repair so hopefully I get this resolved at some point, but thanks everyone for the info I'll keep you updated.
I bought this g2x off craigslist 2 days ago. Love it, works great, easy to root, awesome roms. ordered a sim card from tmobile, got it next day air, activated it on a monthly 4g plan and have had invalid sim message since. Tech help thought I had been sent the wrong sim card, said my phone needed a "uicc" card and the card I was sent was a "gva" card. So with instructions from tech help I went to 2 tmobile stores. Neither store knew what the heck a "uicc" card was, said they only had one type of card for my phone. they tried different sim cards at the stores but all have the invalid sim message. Any ideas? Is the phone just messed up?

Sounds like the sim reader is messed up.
depends on the rom you running. some are cm7 based, and that was an issue for me for awhile until i flashed on one of the most recent nightlys. anything past 205 iirc. otherwise you can do a reboot and it comes on every other boot, or hold the volume up button while it boots until you see the blue LG splash screen and you no longer get that error.
All so it could be possibly blocked for non payment of the previous owner.

negative. its all in the rom reguarding wifi calling. considering ive had tmobile for 9+ years on the same account, the invalid sim has nothing to do with that. i too bought my g2x used, and never had the issue until i flashed on a rom. the stock gingerbread software never gave that issue. i could flash back an older nightly right now and get the invalid sim error message, and do a reboot holding the volume + button and the invalid sim message would go away.

Wondering if anyone can help, im using team Eos European 3g rom zoom. now i tried 1 sim card and the 3g works perfectly but when i try my other sim, i enter the pin code on screen , it accepts it, then immediately says "Sim card removed, the mobile network will be unavailable until you restart...." .
The sim card definitely isnt broken because it works in my phone and 3g modem on my pc. I've tried restarting the xoom with Wifi off and no luck.
Thanks

how old is that "other" sim card? Reason I'm asking is that sim cards use different voltages and old cards tend to cause problems in modern devices.
Around here, providers usually swap sims for free if you say that you've got a problem with one, so I'd go for an exchange if your sim is older that maybe two years...

Its actually brand new, got it on the weekend. It works perfectly everywhere else. I think i'll go to the provider anyway today and see if i can try a sim swap.
This really is baffling me now. I went back to the providers store and tried a different one of their sim cards and it doesnt work either. I just cant understand why my xoom can read certain providers sim cards and not others? (Its definitely not network locked). Could it possibly be the type of sim card (as in a 32k vs 64k etc)?
Any help would be greatly appreciated
New guy here.
I recently purchased an AT&T i727 with the plan to use the bring your own phone program with straight talk. Even with the sim card activated, the phone reads "No Sim Card. Emergency Calls Only". I've used the sim card in other phones, so I know it's functional. I've rooted the phone and installed different roms, but I still get the same error. I can't edit any of the APN or network settings because it tells me I need to have a sim card inserted to do so.
I feel like I'm not super clueless at things like this, but I've done everything I know how to do. Any help is greatly appreciated.
Take it easy on me guys.
Thanks in advance
Sound like the phone isn't unlocked. There is a thread here on how to unlock it for free. Look in the general section.

Assuming the ST SIM is at&t SIM card , and it was working before , the problem might be somewhere around your phone , either SIM card slot , bad radio or blocked-from-network Skyrocket ... is it a craigslist phone ?
It is an AT&T compatible ST sim. I've already entered codes to unlock it and they all said the unlock was successful.
I actually purchased the phone on eBay. (I'm sure everyone will laugh upon reading that)
If the sim card works in other phones and doesn't work in your skyrocket but you have it in the correct way in the sim slot then it's gonna be your sim card slot. With ST your phone doesn't have to be unlocked for the sim card to work in it. Trust me on that I'm using my skyrocket on ST and have used about 10 different AT&T phones on ST and none of them were unlocked until I sold them. You'll need to get ahold of eBay and paypal (who you hopefully used) and try and get your money back. Otherwise you have a really expensive mp3 player.
Sorry for the bad luck but that's what it looks most like to me. I used to work for AT&T and that's the logical problem. I would say try and get a warranty for it but I doubt it still has a warranty and even if it did AT&T and Samsung wouldn't do anything about it because a problem with the sim card slot is considered physical damage. You'll just have to try and get your money back for the phone.
Just my advice and $.02
