oy. yeah that would make me a little angry.
question: have you tried the
Phone Info trick/hack?
download Phone Info from the market to do this easier than the Dialer Code
open the app, and then go into Phone Information--then scroll down to the 1st drop down menu (it'll say CDMA + LTE/EVDO AUTO)--
tap the menu--switch it to CDMA auto (PRL)
this turns the phone to receive 3G signal only.
instsantly, you should see the top of the screen @ the notification bar change and a few seconds later a 3g icon appear
reason i'm saying this--
i had it on CDMA + LTE EvDo auto since i bought it--but would suffer when not around a 4g signal, wouldn't ever even pick up 1x. so i switched it to CDMA auto (PRL) and now i get 3G signal everywhere that i couldn't get 4g signal.
give that a whirl---if you already have, then forget i said it
granted--this doesn't fix the reason why you're not getting signal everywhere,
but like me,
you couldn't get 4g or 3g signal. so, i told the phone to search for 3g signal only--and voila, it worked. i picked up 3g in the same exact spot that 2 minutes earlier received none.
