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.

Sony k800i configuration error


You need to get the Settings for Internet/Wap and MMS from your Network Service Provider. These settings are usually sent as a text msg. When you receive the msg. choose save or install on your phone. Or get the settings directly from their website. The MMS service doesn’t always work between networks.

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!
