When i got my KU990 i got a new sim with it but i had to ring up my network provider and they gave me instructions to enable it. Basically they have to send a signal to your new sim so you put the phone on and the sim in then they tell you not to play with the phone for an hour or so while this is happening. It also makes your old sim card un-usable other wise you would have 2 sims with the same number.

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

I have a viewty ku990 v1.0 locked on orange, when I put the sim in it come up with inactive usim. I would like to unlock my phone so I use my old o2 sim.

To remove usim locked you need to get unlock code. You can get unlock code at

They can supply unlock code for any LG. Once you have it you just type unlock code via phone keypad.

You MUST have sim card from network phone is locked to to be able to access phone menu! Without such sim card do not purchase unlock code.

My lg viewty ku990 says inactive usim whats that mean can i fix it

the sim card is located behind the battery, the contacts could be dirty from being in your pocket, your service is over with your current cell bill, or you have to talk with your current service provider and they can offer you a new sim card or try to reconnect you.

Yesterday I shortly inserted sim of colleague, to test his sim. Worked fine, but since then, I get message Inactive USIM on screen.

Apparently the contract had ended the same day. I thought it would be next month.
Found the message bit confusing.

Inactive usim

The same thing happedned to my one. I switched the phone off then on and it worked. If it still doesn't work it is probably not the right simcard. Also the dude at the shop when i bought it put the sim in 4 me. Their was a sim in the box for the mobile.
