4S eSIM does not offer a plan that gives truly unlimited high‑speed data for Asia; every plan that carries the word “Unlimited” has a fixed data cap and, once that cap is reached, the speed drops to 1000kbps. For travelers who need a large amount of data, 4S eSIM provides fixed‑data options such as the Asia+ 50GB plan, which gives 50GB for 90 days at $63.76 USD, and the Asia+ 20GB Unlimited 5‑day plan, which delivers 4GB per day (20GB total) for $27.96 USD. These fixed‑data plans can be more cost‑effective unless a user requires an extremely heavy data consumption without any throughput throttling.
4S eSIM does not provide a phone number or SMS capability for its Asia eSIM plans. The provider offers only data‑only solutions. Travelers can still use VoIP applications such as WhatsApp, Telegram, and iMessage over the data connection for calls and messaging.
The Asia+ plan includes China, Hong Kong, Indonesia, Japan, South Korea, Malaysia, Philippines, Singapore, Thailand, Taiwan and Vietnam. The Global plan also covers these Asian countries in addition to many non‑Asian markets.
