4S eSIM does not provide a true unlimited data eSIM for South Asia; all plans listed for the region have a fixed data allowance. The plans that include “Unlimited” in their name actually contain a hard cap, after which the speed is reduced to 128kbps.
Traders who need larger data budgets can choose the fixed‑data plans that offer the most data. For example, Global 50GB – 30 days gives 50GB of high‑speed data for 30 days, while Global 20GB Unlimited – 5 days supplies 20GB over five days before the speed tapers. These plans are the closest alternatives to an unlimited experience while still keeping costs predictable.
4S eSIM does not provide South Asia eSIM plans that include a phone number or SMS capability. Only data‑only eSIM options are offered; travelers who need voice or messaging will generally rely on VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection, but they should confirm that these services are available in each South Asian destination before purchasing.
The 4S eSIM Global plan covers Bangladesh, India, Sri Lanka, and Pakistan in South Asia. The plan also includes many other regions worldwide, but those are the South Asian countries it serves.
