About this app

CST ON is the new way to watch television on your iPhone and iPad — simple, fast, and always with you. Watch television wherever you are, anytime.

Enjoy TVS, RTP África, and Reino Infantil (with more channels coming soon!), for just 25 dB per month, without using your CST mobile data plan. All with quality adapted to your connection and an optimized experience for mobile use.

Missed a program you wanted to watch?

With CST ON, you can pause, rewind, and review the last 7 days of programming, so you never miss what you like most.

By using the mobile data from the CST mobile number associated with your subscription, internet traffic is completely free, not consuming your data plan.

You can also use the service via Wi-Fi or other internet networks.
