Lg LM-K500UM is network locked to Boost Mobile. I've used it for approximately 6 months on prepaid plan. I just received a sim from StandUp Wireless, a program for people who get government assistance. When ordering the sim, StandUp asked for my IMEI to see if my phone is compatible. They say it is. But when I tried it, my phone says invalid sim. I tried to get unlock code from Boost, but they said I had to use phone for one year before they would agree to unlock. Please help?!?!
