    I have the exact same problem. It happened after a PIN was entered incorrectly on my phone three times. I tried all sorts of things, including phoning my provider (Vodafone) and having them try various ways of unlocking it and searching on the internet for ways to fix it. I ended up having to get Vodafone to send me a new USIM card, which they did at no charge since I have my contract through them.



    If you can find someone who has the same network as you, you can at least try putting their USIM in your phone and if it works, that means the problem is with your USIM card and not your phone. The same goes for if you stick your USIM in someone else's phone on the same network -- If their handset then reads"invalid USIM card" then you know for sure it's the card.



    I don't know if it's a common problem with the LG Viewty, but I found lots of posts out there with people who had the exact same problem.

It wont let me on my phone it has came up Invalid USIM card


This is because you did not insert the correct SIM card. If you were provided with a SIM card when you bought the mobile, you can use only that SIM in the mobile. If you want to use other networks you need to unlock with the current SIM card. Unlocking can be done at www.mobile-unlocker.com within minutes.

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.

My ku990 doesn't recognize usim


Is the phone unlocked, because if it is not, and you put a different USIM into the phone than what came with the phone, it will not work.

Hope this helps...

My lg viewty invalid usim


Debbie invalid usim means its been barred by the network, so whom ever the network provider is for the phone you will have to give them a call and ask them to un barr as you have just brought it. We brought on off ebay at christmas on orange as we're on orange and had the same problem. We called them and they took the barr off straight away, no charge. Jan

Invalid usim


It sounds as though the phone is locked. When I had this happen to my Samsung A707, I had to send it back to Samsung to get it reprogrammed. (There are people who have bought the necessary hardware to interface with a mobile phone's OS, but I preferred Samsung themselves.) This was a free service (except for shipping) from Samsung. If you contact Motorola, they might be able to simply reprogram the phone for you.
