Since the DTI has successfully implemented the removal of expiry dates on gift certificates (GCs), the NTC is now also contemplating to do the same with mobile prepaid load.
In an interview with NTC for the GMA 7’s SONA episode, the National Telecommunications Commission (NTC) is stated that they are studying the possibility of removing the expiry date of prepaid load for cellular phones.
Once implemented, this could mean that any amount loaded on your prepaid SIM card will never expire unless you use them or throw the SIM card away.
This follows a similar reasoning of DTI with regards to GCs — that those amounts are like currency anyway and should not have any expiration dates.

We expect that telcos will strongly oppose this move as this could affect their sales and bottom-line. If DTI can do it, we’re hoping NTC can do it too.
Currently, the expiry dates or validity of prepaid loads are as follows:
Php30 – Php50: 15 days
Php100: 30 days
Php300: 75 days
Php500: 120 days
Prepaid load cards also remain valid for 1 year when they are un-used.

I hope NTC will have the balls to implement this.
