Plan Description Hotspot Sharing Total XX GB Fixed high-speed data amount with no speed throttling until the data is used up. Hotspot sharing consumes your total allocated GB. No other limit. Unlimited 10Mbps Unlimited data at 10Mbps speed. Total GB for hotspot sharing is calculated based on the number of days selected, using the formula "days - 1" GB. For example, a 7-day plan allows 6 GB for hotspot sharing. Unlimited Truly Unlimited High-Speed Data For example, if you purchase a 7-day Unlimited or Unlimited 10Mbps plan, the hotspot data available for sharing would be 7 days - 1 = 6GB.
