yourlocalfbiagent wroteif you are searching for unlimited with IDM but with no FUP, you have to get open speed limited for example OS 200GB package like I did and then get the unlimited evening package for 12,000 extra so in my case it's 82,000 a month, and the benefit of this is that it has no FUP so it won't throttle your speed after 13gbs a day like i had with iplan premium.
Actually, besides the iplan I considered the 150 gbs plan with unlimited night. You mentioned the unlimited evening, to my understanding, it only doesn't consume data from streaming (selected apps) and gaming. Is it like the unlimited night traffic? If not what are the selected apps?
