Saily does not provide a truly unlimited high‑speed data eSIM for South Asia. The highest‑cap plan listed is the Global UNLIMITED 30 days, which offers 30GB of data for 30 days; after the 30GB limit is reached, the speed drops to 1024 kbps. Because the data cap is still defined, the plan is not unlimited in the strict sense.
Travelers who need more data can choose one of Saily’s fixed‑data options. For example, the Global 20GB 365 days plan gives 20GB of high‑speed data valid for an entire year, while the Global 10GB 180 days and Global 5GB 60 days plans provide 10GB and 5GB of data for 180 and 60 days respectively. The Global 2GB 15 days plan is also available for shorter stays. These fixed data plans are the only alternatives to the capped plan and may be more cost‑effective for most visitors.
