You will not get rebates unless you recontract without the handset. If you're still under BEMSP, no more rebates. Anyhow, try to call 211.
Recontracting with bill rebates is now only allowed if you will avail of the MyLifestyle Plans.
Some of the monthly rebates being offered now for recontracting are Php 125.00 for Plan 599, Php 300.00 for Plan 999 and Php 350.00 for Plan 1499 just to give you an idea.
Note that these are smaller amounts compared to what they used to give.
