Hi. I realy need some help now.
It all started when I brought my own phone the Xperia Z Ultra to wind and got a sim card from them. I notice the internet wasn't fast so I called them up to help diagnose it. They told me to shut off my phone, take out the sim card, put it back in and turn on my phone again. After I did that I got an invalid sim. Wind no longer works with my phone now. I tried replacing the sim card but it didn't work. I tried other sim cards from different providers and they all work, just not wind. I called them up and accuse them of blocking my phone from their network. I ended up getting a phone from them to use their network after my contract with Bell ended.
Can you guys here at XDA help me ou?

I bought a cheap ATT Go Phone for the SIM card for my iPhone. I've activated the phone and the SIM card but the crappy phone keeps saying SIM CRASH, and nothing beyond that. I put the SIM into the iphone and it just says "searching" in the area for the signal strength. Do I need to call ATT about this one

Just like most companies, AT&T provides specific SIM cards for their specific services...hence the Go Phone card not working the way you want it.
Get a card from AT&T for your IPhone.
Cheers,
I know this thread is quite old but I have the same issue when I insert my sim card in the gophone in came with or any other phone I tried an unlocked iphone 3G and an unlocked HTC HD7. The most surprising part is that my HTC Desire doesn't seem to have any problem with this card.
I would really liked to get it to work on my HD7 but I had no luck.
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.
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
I have a g900t from Tmobile I repaired the imei everything works just fine I gave it to a friend of mine thinking since he had metropcs he can just pop in his SIM card and it would work just fine but it doesn't.. I unlocked the sim the same day I repaired the imei.. When my friend told me it was not working I found it strAnge so he brought it back and when I checked it out it does not get any metro signal nor did setting the apn help either...but when I put in another metro sim that I had laying around it did allow me to call metro customer care for some reason it's his sim that will not jump on metro network they are both metro sims his is activated but won't work on the phone and the one that I had lying that is not activated does at least allow you to contact metropcs if it's in the phone...I know.. Just get another sim rite? I guess that what I will do.. But first I would like some info or a solution instead of buying that outragousely expensive SIM card "$5" and solid ideas anyone? A working solution? And bye the way I used a z3x to unlock sim... How do I get HIS sim working without driving two giant blocks or walking five eternal minutes? To buy a new sim... The phone works fine with att,tmobile, and so far the two metro sims that are used but not connected anymore.. Thanx for reading...
