OMG! So those from Quezon and Samar who get Duo/Superduo will be charged regular rates if they call landlines aside from Duo numbers and Globelines? That is highway robbery!
Why would you even bother getting DUO in those areas? Just Superduo it and call globe handyphones OR Get prepaid and acquire as much immortal calls you can so you only pay 3 pesos a minute for calls
