Once you have the device, no turning back.as far as i know they dont accept 2ndhand phone. and if you want to disconnect your line. you can just compute the amount that you need to pay to avoid blacklisting or you may call the hotline Contact Us
here's the computation:
(Handset Base Price) Minus (Cashout) divide (to your Contract with Globe) Multiply (to remaining months) Plus (550 for termination fee)
(Handset Base Price) (Cashout) (to your Contract with Globe) (to remaining months) (550 for termination fee)
23,000 - 3000 = 20,000 / 24months = 833.33 X 18months = 15,000 + 550 = Php.15,550
I hope you understand this
it is not possible to return the unit, since you are just in your 6th month of your contract, you are to pay disconnection fee plus yung remaining months that your have to pay for the device.
