Help LG G2 VS980 not detecting/connecting to mobile network..

[prateeksahoo]

I am in India at the moment...i have 3 Verizon G2 phones...SIM cards work fine on 2 of them...On the third one...it does not detect the mobile network...sim is detected ,coz it gives no alert...and when i search for networks...the networks are shown...it just doesnt connect to the network...the sim cards work fine in other phones...in the other G2 phones and in a HTC DROID DNA...so its not the sim at fault....

Have tried multiple SIM cards from Vodafone/Loop Mobile/Airtel...none of them work on this particular phone..



What can be the problem ?

Please help me out...otherwise will have to send the phone all the way back to USA...
