okay i just discovered that Tata play fiber mentions which building they operate in ,instead of lying to first to collect your number
the way how majority of ISP's work
step 1
Give your Phone number
step 2
Receive OTP
step 3
UR BUILDING DOESN'T HAVE OUR Fibre
step 4
get spam ads about spam protection (iykyk)
someone at Tata play really thought about this problem and delivered a solution
more of a QOS service solution, which 99.99 customers won't notice, but It's still very helpful
