Just learned today (thru one of my staff in Manila and verified by @arnoldgamboa) that Smart Bro Rocket has finally cut off subscription to Smart Unlisurf plans.
When Smart Bro Rocket was first released, they allowed subscription to UnliSurf 50 and UnliSurf 200. However, they warned that this will eventually be reverted to a bucket plan by September 30 — at Php180 per 200MB. The default internet rate is Php15 per 30 minutes.
It’s still the 16th of September but subscribing to UnliSurf has suddenly become invalid. Will get official word from Smart regarding this switch and will update once we get a response.
