Is the phone locked to a particular network?
You may need to unlock it, so it works with your SIM.

you will have to purchase the unlock code.  There are several website that do this and it is about 30 dollars.  Make sure you use a safe and secure website.

SOURCE: 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

well, if oyu have falshed the phone, the final thing you must do is after booting it up again, simply press: 142358#*#, whilst an unsupported SIM is inserted, which will thus reboot the device!

My lg kp500 keep asking for active usim how can i fix this


Did you insert any usim into it? If you did, maybe it did not sit well, all you need do is to shock the usim with paper or anything that will make it hiold firm to the phone.

And if youn did not insert any sim I think you need to do so, to keep your phone going.

I wish you the best.

Inactive usim" comes up when i put my 02 sim card in my ku990 lg phone, why is this


You need to go to a phone shop that stocks 3G sims. Get a $10 sim (a blank free one probably will not work). You didn't say whether you were on a pre-paid sim or a plan. Anyway call 3G and ask them activate it. Get the number off the sim before you ring them. They will need U to quote that. hope it helps :o)

Lg kf700 wont accept any sim cards,


Hi,

it sounds weird that it worked before with same sim card. Generally USIM locked message means phone is locked to network and you need to unlock it with network unlock code to remove USIM locked and use phone on different network.

Insert USIM


If you haven't already done so, try this: take out the SIM card, wipe it down with a dry, soft cloth, and reinstall it WHEN the phone asks for it.
