4S eSIM does not offer a truly unlimited high‑speed eSIM for South Asia. Every plan labeled “Unlimited” contains a fixed amount of high‑speed data; after the limit is reached the speed drops to 1000kbps. Travelers who need larger data volumes can choose from the fixed‑data options, such as the Global 50GB – 30 days plan or the Global 20GB – 7 days plan. These plans provide the full data allowance without throttling and may be more cost‑effective for heavy‑data users.
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.
