About this network
Smart Communications — the wireless arm of PLDT and one of the two dominant mobile operators in the Philippines.
What it's used for
- Mobile data and internet for a very large Philippine subscriber base, including the Smart, TNT, and Sun brands.
Notable
- A major "eyeball" network — addresses here are typically consumer mobile devices behind carrier-grade NAT, so one public IP maps to many users.
- Owned by PLDT; competes head-to-head with Globe Telecom, with newer entrant DITO as a third player.
Interesting
- Prepaid dominates the Philippine market, and Smart's prepaid brands (TNT, Sun) reach a huge, price-sensitive user base.
