Since you say it is a GO phone, you need to call ATT and they may help you with that.

SOURCE: Sim Card Problem In LG Vu

This happened to me too. A temporary fix is turn off your phone and put it in front of a really cold air conditioner for about ten minutes. Then turn it on but make sure you keep it in front of the ac to keep it working. What happened is your sim card reader has a thermal problem so you will need to take it in unless you want to spend all your time in front of the ac (which will get expensive...)

SOURCE: Cannot import contact from sim card to iphone 3G

Turn off the iPhone before inserting the sim, insert sim, turn on, import contacts. If you put the sim in the phone without restarting it for some reason it doesn't get all the contacts sometimes.

SOURCE: Invalid sim

That's cause your phone , you buy bundle with sim card, so provider protect phone to use sim by other provider, or you ever set phones password to use sim, if nothing like that go to service center to solved your problem.

I've got a sim card slot in my HCL Me netbook. I expected it to work as common. but unfortunately, I'm unable to get any response. just tried dev. manager, new hardware wizard, jst everything....


When you purchased the notebook, did you pay for the 3G cellular card to be installed? A lot of notebooks have a blank SIM slot in there, meaning that it does nothing. My laptop had to be specifically purchased with a 3G card to be able to use the SIM card.

When i put my sim card in my phone it says invalid sim


Either the phone is locked to a network or the phone supports only 128 kb sim (from 3G networks). In both cases you will need an adaptor card like u-sim or Tornado-sim.

Invalid usim card


unlock phones are so unperdictable...there may not be a fix for this issue..other then getting an AT&T phone....and even if u are able to get it to start working again more then likely u wil continue to have many more isses..mainly becuz of the network changes..for example....using 3g and 3g only...last year the AT&T network was stil using both 2 and 3g network and there was even a few 2g SIM cards being sold in stores...now it almost all 3g..which of course complicates many things...even if u own a 2g AT&T phone a 3g SIM card can be and will be used on that phone....with unlock phones running on the 2g network the issues with not having a SIM card where possible...it was still unstable when wanting to use data services....but voice services were possible...now with everything going 3g...its makes things alot more complicated with AT&T if using a phone without SIM cards...if ur phone has the fuction to beable to shut off 3g networking and run on 2g.(like the apple iphone has) then try that....good luck

Hi can u help with my iphone 3g. it is stuck on invalid sim and emergency mode. how can i get this off? and is there a way to unlock a iphone 3g 3.1.3?


Here is what you have to do. Get a friend that is on the same carrier as the sim card that is in your phone.

Next take your sim card out and put a friends (same carrier) sim card in and restore it. When it is done it will still be in emergency mode. When it says invalid sim put your original one back in it and after about 30 seconds it will go back to normal.

This solution just fixed my iphone 3g so this should work.

Best of luck, Michael Proctor

Wht does invalid usim mean on lg kp 500????


USIM is 3G only SIM card and is working ONLY with 3G enabled devices. LG Cookie isn't 3G device so it won't accept USIM.
