Jetpac’s plans that reference “Unlimited” in their name only provide 3GB of high‑speed data per day for the validity period; after that limit is reached the speed drops to 1024kbps. Because of this daily cap, true unlimited high‑speed data is not offered for China.
If you need a larger amount of data without daily limits, Jetpac provides fixed‑data options such as the China 40GB plan for 30 days or the Global 50GB plan for 365 days. These fixed‑data plans can be more cost effective for travelers who use a lot of data but do not need an ever‑ data supply.
