Few months ago, you can play Clash of Clans or any Supercell game aps like Boom Beach or Hay Day using your SMART Data for FREE. It might be an open port bug from SMART or their marketing strategy to lure more Clash of Clan users.
But not anymore, even using PSIPHON VPN app or any tunneling device will not work. But dont worry SMART created a special promo that allows users to browse the Internet without data limit, plus a FREE one day access to Clash of Clans!
How it work?
First load a regular SMART load, then type UNLI20 and send it to 5555. You should receive the screenshot below.
This promo gives you access to unlimited browsing for 1 day or play any online mobile apps or games.
Then after 24hrs, access to unlimited browsing or playing online app games will stop except for Clash of Clans.
Another free one day access to COC will start!
To summarize SMART UNLI20 from 5555
1st day ~ Unlimited Internet, emails, or online apps and games like Clash of Clans
2nd day ~ Clash of Clans only, no more unli browsing.
Enjoy playing COC!
