I have Smart and BTL cell phones,
Every time if I go out I have to bring these two cell phones,
Cuz in remote place smart is beta than BTL,
but in City Limit BTL is beta than Smart
I know there are some cell phones could accepted GSM & CDMA both sys in one cell phone,
So I would like to know
Has anyone ever try that before?
What model of cellphone could accepted GSM & CDMA sys.?
What is MHz for GSM & CDMA each sys.?
