Short answer: this means the plan includes a high-speed data quota for the full validity period. After that high-speed quota is used, you can continue using data at a reduced speed until the plan expires.
What is included
- The plan includes a total amount of high-speed data for the full validity period.
- After the high-speed data quota is used, the plan does not immediately stop.
- You can continue using data at a reduced speed of up to 1 Mbps upload/download until the plan expires.
Why speed may slow down
If your unlimited plan becomes slow, the most common reason is that the included high-speed quota has already been used. The remaining unlimited data continues at reduced speed.
How to get more high-speed data
If top-up is available for your plan, you can recharge the plan to add more high-speed data. A top-up can also extend the plan validity period.
You can check your current usage, remaining high-speed data, validity, and top-up options from your 4S service page.
