You may want to refer to this thread for the Huawei P6 and Globe Plan http://community.globe.com.ph/t5/Guidelines-and-Announcements/Huawei-Ascend-P6-Exclusively-at-Globe/td-p/26732#.Uf8ywKyLCQU
For the Cash out depending on the Plan http://www.globe.com.ph/huawei-ascend-p6
And the combos would depend on the PV of the plan that you get (I don't think they give PV equivalent for the P6... just the cash out for 24 months 0% interest on handset cash out via participating credit cardholders such as Allied/PNB, BDO/Amex, BPI, Citibank, HSBC, RCBC Bankard, Security Bank/Diners Club, Unionbank, and Eastwest Bank.)
So for your query, Plan 999 would give you 900 pv/month while plan 999 would give you 1700 pv/month. You might be required to subscribe to a surfing bundle with the phone.
