right now, internet works fine.
but i can't send sms and i can't make calls. (actually, they DO work, cuz i have received text messages, but it was like.. 4 hours after my friends sent them. xD
and i CAN make calls, but 99% of the time, the call loses signal within the first ringtone i hear.)
and i don't get why my signal bars keep flashing.. it'll be 6, then the next second, it'll be zero. then back to 6 and then zero..
but on the boost coverage map on their website, i am in the dark green area (best coverage)..
so why is the signal acting so strange? and can anyone help me fix this?
roaming is off. it is stock rom. and i updated prl to 61007.
