I want to clarify few things
1. Jio won't give STB for new users opting for Bronze or Silver Packs. If you want STB then user need to take Gold or above pack
2. After 30days, if user wishes they can downgrade to Bronze pack.
3. In Bronze & Silver plans as OTT apps not included you can't watch even FTA channels. You need Gold or above plan to watch even FTA channels.
4. If you take Gold or above pack we can watch Star, Sony,Zee, Viacom, Sun network and roughly around 30 FTA channels.
Finally, last and best thing Yes you can install JioTV App on STB and can watch 650+ live channels but the app won't work through remote you need wireless mouse. You need to sideload JioTV APK as it is not available officialy on Jio Store.
So, for users who need Only Internet & Live TV they can take Bronze pack.
