[Q] SIM CRASH on a Go Phone?

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.

[Q] INVALID SIM CARD HELP???? Please Read

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??

Any help in any way would be greatly appreciated... Thanks in advance

First of all this is P990 forum the P999 can be found here http://forum.xda-developers.com/forumdisplay.php?f=1114
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.

[Q] [Xoom2] APN disappears. Sim card troubles. MZ616

I visited my sister in Germany and she gave me a Vodafone branded Xoom2 UMTS (MZ616). I was able to flash it with ICS and everything works great.
I got a new sim card from ATT (I live in ghe US)and put it into the tablet. This is were my issues start.
I see no APNs. When I add an APN it disappears or I cannot save it.
I tried everything. Sometimes when I try to manually search for the network ATT pops up. When I select it, it will show bars for a short time or i may get a "sim not authorized for this network error.". When I add data roaming, it may shows the ATT APNs for a short time.
I also get an error when trying to add a simlock I get a "no sim card" error.
I am stumped. I searched the various forums and I get a lot of inconsistent info.
Is this issue related to the tablet being locked? Does that even matter? Is this some sort of region issue? Do I need to unlock the bootloader or should I use a different ROM?
I do not think the sim card is faulty.
Any help appreciated.

Sim Card Size????
So I compared the old Vodafone sim card with the 'new' AT&T sim card. The plastic outline of both cards seesm to be micro. However, the gold plated contacts on the new cards are definitely micro sim, but the old Vodafone card seems to be old school size (not sure what that size is called). If the size of the gold plated material matters, then this may be may issue. Like I said, above, when I first boot into the tablet with the new sim card I will have bars for a short time, but they disappear and the sim card does not seem to be recognized.
Can someone knowledgeable on sim card size matters as they pertain to the Xoom2 please weigh in and let me know if this is the issue?

I took a pic of the sim cards. From left to right: Old Vodafone sim, new AT&T sim, 2FF (mini sim card) for size comparison.

Please post all questions in the Q & A section. Thanks! Thread moved.

[Q] Skyrockt on Straigh Talk sim issue

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

no sim card - no service

Hey guys. I just got a moto g today and I find this quite annoying, because when I turn it on before unlocking it it comes up with an error saying "Vodafone NZ, no sim card - no service". It's odd because of the fact that I am still able to use the phone in both using the internet and text / call. I've come to realize that the no sim card part is due to the fact that it's, perhaps, referring to the second sim card slot being un-used. But the no service part does not particularly make sense. Also when I unlock the phone it also has a red slash going through a sim card on the top left as well as the red slash going through a graph, referring to connection.
I got the phone today and when I got it I had to get a new sim card and load my current number on it at the vodafone store, the guy did it for me.
Any help will do. Thank you.

Yeah, it's referring to the other sim card, both sims are always displayed. When I had two sims in, they both showed the carriers. "Vodafone NZ" is one and "no sim card - no service" is the other.

Okay. So essentially what it is, is that the slash through both the other sim and connection is refferring to having both no sim and connection via the 2nd sim card? so I need to get a 2nd sim in order for it to go away?

Yes to both questions. If you get a second sim, it will look like the other one.
There are some mods to get rid of it, but I think it's a much of a muchness...

Fair enough. I can only presume it got there because the vodafone guy put the sim card in both slots, therefore activiating the 2nd one. Fair enough though. It's not doing anything just annoying my ocd ;D !
Thank you so much for your assistance.

You're welcome.
Mine has both, they're there by default. It's okay, it's a common complaint... XD
