U mean, they are blocked in Jio 4G / Jio-Link, but not in Jio Fiber??? Hmm, may be possible. If allowed, then everybody will find the easiest way to completely use their daily 4G data, which is very bad for wireless networks...
Airtel is much better in this case, afaik, as they don't care much about what you use their connection for... Right now, I am using 50Mbps Local BB (with BW purchased from Airtel) as primary and BSNL 799 (3.3TB @ 100Mbps) plan as secondary (mostly for kids' online classes). Jio is coming to my town soon. May be I will take Jio fiber as well, as a backup tertiary connection and ditch my current Jio-Link connection (used by my parents).
