I'm having the same issue and when I dial the #72786# I get a system error message that the number or code entered is invalid... now what? ( Have tried a few times...same result!)
Hi LGHoo496! What's your phone make and model? See, for iPhones, the code is ##873283# then call. If it still doesn't work we'll need to take a closer look at the problem. Would you mind sending us a private message with your phone number and pin? We'll be glad to look into this situation asap.
Sorry to hear that, @Arron! Are you able to make and receive calls? How many bars are you getting? What's your device model?
