I am on HighSpeed 10G. The next plan, LightSpeed 20G is $25 more. If I already exceed my monthly usage by 5 blocks ($2.95*5=$14.75) and then change from HighSpeed to LightSpeed, do the extra data blocks go towards the 25GB (and only get charged the $25 upgrade) or what?
TCL still charges $25 more (than the HighSpeed 10G) if you are on LightSpeed 20G and only use <10GB so I would have to downgrade manually, correct? No data stacking or automatic discounts.
