The 1599 you mentioned is actually a Plan 999 + 600 monthly cash-out for 24 months at 0% installment via major credit cards except Standard Chartered.
The Php 600 a month would be billed through your credit card and not through Globe so to answer your question, YES.
I think this was done so as Globe would not take the cudgels in billing you the addtional 600 a month and instead just limit your liability to Globe to just your subscription of Php 999/month. In effect, what will happen would be the following:
Appearing in your Globe Bill is just Php 999 for the monthly subscription.
Appearing in your credit card bill is Php Php 600 for 24 months.
Therefore, total cost for the whole thing is Php 1,599/month.
thank you...another question...do they allow us to use the credit cards which are not on our names?...when i called up the hotline the other day, the agent said that it's possible...is this true?...tnx
