Lg displays 'insert usim' and does not allow any functions


sounds like its either one of 2 things:

1. the sim card is locked. (you'll need to call your service provider & get them to give you the puk code to unlock it)

2. the sim card has crashed (go to your wireless provider & get them to provide you with a new sim card)
hope this helps...

K850i insert USIM or view demp


If the sim fits its the right type of card, if it needed a certain carrier (ie Telstra) SIM Card, your putting the sim in it would have locked it not just not read it. Either you put the sim in the wrong way, make sure the metal on the sim matched up with the metal grates on the phone OR more than likely the phone is faulty and needs to be fixed.

I need unlocking lg u890


i had a lg u890 mobile phone that i got unlocked but it had the same proble where i swithched on my phone it used to ask for the usim code..my old phone was locked to the 3 nt/wrk i got it unlocked so i could use my 3 nt/wrk sim card or any network simcard but i used vodafone 3g sim card.the code i used with my vodafone 3g network simcard in phone when switched phone on & it asked for usim sim code i inserted code i got & it shut the phone down then on again then it wld work with vodafone no bother at all it even came up with vodafone uk etc.but i had to reconfigure the sms/text telephone number aswell as reconfigure the mms settings & numbers etc aswell as reconfigure wap settings from 3g network to vodaphones.but after i got it all unlocked & settings changed etc & inserted a different 3g network simcard ie vodaphone/orange/o2/3g sim/t-mobile/tesco sim/virgin sims & switched phone on it asked for usim code i tryed the code i have & inserted the same code i have it/they switched phone off & then back on & all network usim card worked with no problems at all.the code i have is.>>> 142358#*# thats 142358# * # all 1 item/action.once you insert that 142358#*# thats it your phone will shut down then restart up & go onto the network usim card you want to use or inserted before using code.but 1 thing tho please remember if u switch off your phone or your phone switches off as batterys run out no power u will need to insert the code again.& another thing code wont work if your phone switches off or you switch it off & plug your mobile battery charger into phone to charge your battery up on the phone & you switch you phone back on when you are charging your phone as the phone will switch on & say insert usim code if you enter the code the phone will switch off & back on again but it will still request usim code.so you will have to wait unto there is plenty of charge in the battery to take phone off charge & swithch your phone on get the usim code message insert code above phone will switch off & straight back on again & then it will go onto your prefured usim card then you can plug your charger into phone again to charge phone up.you can use your phone on charger when u have entered usim code & it switched off & on again & registered with the prefered network.i hope this is of use to you as it is to me.if you try this code & either if it works or not please can you let me knows ty.email watsonwhizzy2001@yahoo.com
