Smart recently announced a new sale price promo offering mobile 3G internet users an extra hour for every hour of usage during off-peak times. That’s Php20 for 2 hours (Php10 per hour) between 2am to 6am.

The promo starts August 7, 2009 and in order to avail of it, you must go to the Smart Mobile portal (m.smart.com.ph) using your mobile phone’s browser and click on the “Free 1 Hour with Off-Peak Internet Plan” link. You must activate it before you can get your extra 1 hour free.

You need to have at least 1-peso load balance remaining in your load in order to activate this. Activation is only between 2am to 4am. If you go beyond the 6am off-peak hours, you will be charged the regular rate of Php10 per 30 minutes.

The off-peak hours indicated by Smart gives us some idea that 3G internet usage is still at its peak even between 12 midnight to 2am. Now that’s a lot of heavy 3G internet users.
