I have tried everything I turned roaming on, on my phone, and dialed #766# or whatever the number is to turn on roaming, I can't remember actual number, but I do know I dialed correct one because a prompt told me roaming was on. I have turned my phone off for ten seconds and restarted, I have taken the sim card out, I have searched for a network, but it says error searching for a network with or without my sim card. I have created a new apn so that the apn is lpv4 instead of 6, I created a new one because I can't edit the original. I have tried everything I have seen on the web but still no signal, I don't need to make any phone calls on it, I use wifi, but I would like to have data and text when I don't have wifi. According to everything I've checked including t-mobiles website the lg v10 should work in Japan, please help?
