Im just wondering I have a principal line and I have 2 supplementary lines. My data pool is 25gb currently however one of my supplementary line i have give unlimited data to use and another is subjected to 5gb only. The funny thing is we our usage are all the same so lets same I as the principal line have used more than 5gb will my supplementary line which is subjected to 5gb data will used at throttled speed eventhough that line have not utilized it. All I am asking is whether the usage of the principal line plus the supplementary line with unlimited data will affect the limited data (5gb) supplementary line.

Kindly advice
