But before you go around trying to add channels on the app, you need to learn how to install SIPTV on your preferred devices because that requires a bit of work. Those who want to enjoy the benefits of using this app will have to add their own channels. Some confused souls assume that the app will be loaded with channels right out of the box, but that’s not the case. However, as already mentioned on their official website, Smart IPTV does not contain channels, so you will have to add your own via an IPTV service subscription. Smart IPTV, commonly known as SIPTV, is an IPTV player with EPG (Electronic Program Guide) that gives you easy access to the IPTV channels that you want.
