in india? i don't think so. that carrier aggregation is for countries where their network is really bad. In india where everyone has cut throat competition and pay each other to use their network towers, no carrier is going to allow another carrier to use their network bandwidth which is already at its capacity.
we need to.enable engineering mode or alike to unlock the bands which we need .[DOUBLEPOST=1557648317][/DOUBLEPOST]and we need at least 3CA for jio and airtel .
jio is doing intra band as well 40 band 10 plus 10 mhz bonding .
