This varies by plan type:
- Daily Plans (e.g., 500MB/Day): You get Unlimited Data. If you hit the daily high-speed limit, you can continue using data at a reduced speed (usually not lower than 256kbps) under the Fair Usage Policy (FUP).
- Fixed Data Plans (e.g., 10GB Total): These plans do not have FUP. The data service will stop immediately once the total limit is reached. We recommend buying a larger plan if you are a heavy user.
