Product Authentication program
Dear Customers,
To protect all LG customers from counterfeit and grey market products and make sure that you receive offi cial
warranty service, LG is now running a product authentication program.
To make sure your handset is a genuine product of LG, ONLY one SMS containing the IMEI No. of your purchased
handset will be automatically sent to LG on the date of purchase.
Once your phone is authenticated, you will receive the message 'Your handset is a genuine LG product. '
The customer shall bear the cost of one SMS for the product authentication program.
In return, you will receive one additional month of warranty for free.
One additional month of warranty covers only mobile phone, not batteries and accessories.
The IMEI No. sent to LG guarantees your handset to be free from manufacturing defects during the warranty
period from the date of purchase without proof of purchase or warranty card.
