Throttling is where your speeds are automatically reduced when you exceed a specified usage limit until the beginning of your next cycle.For example, if you had a plan with a 20GB monthly limit, you could only experience 4G speeds until you reached 20GB of usage, then the system would drastically cut your speeds until the beginning of your next cycle. While throttled, you would not be able to do many things, including video streaming. So, if you went through your allotted 20GB in the first few days of a cycle (which is very possible), you'd have to wait nearly a whole month before you could return to 4G speeds.Our plans are NOT throttled. You can stream videos, music, etc. from day one to day 30 of every cycle.
