Sun Cellula's new promo: Easy Line, Good or not?

Sun Cellular Easy Line

This one is like a Plan 250 postpaid account that can be considered as Postpaid/Prepaid account.

What this EASY LINE DOES
- Free Sun to Sun text (SMS) for one month
- Free 20 minutes of Sun to Sun calls PER DAY
- Fixed Php 250.00 a month
- In excess of the 20 minutes per day Sun to Sun allocation, you have to reload your pre-paid account (same number as your line) to be able to use the service.
- Same as the one above, you need to reload if you are going to call or text other networks even if you have not used any of the Sun to Sun Text or 20 minute Sun to Sun calls.
- Pay early and you receive a discount to be deducted in your bill!

This means, you can control your expenses more. I am not at a premium plan with sun cellular so I cannot change but, If I were just on a prepaid, this would be my choice since I will use my Sun for Sun to Sun only.

Is this a good plan for Filipinos mobile phone plan budgets or not?
