Hi, so i have been using my razr quite awhile now but recently i have been unable to get a 4G signal after i did a factory reset on my phone for something unrelated. I know getting a 4G signal usually depends on where you are, but before the reset i connected to 4G just fine where i live in so. Cal, but now i can only connect to 3G or wifi, this has been going on for atleast a month but it never bothered me until now. Thanks
