4S eSIM eSIM Data Plans for East Asia

4S eSIM does not currently provide a truly unlimited high‑speed data plan for East Asia. The plans that carry “Unlimited” in their names, such as Asia+ 3GB Unlimited or Global 20GB Unlimited, have a fixed data cap and a reduced speed of 1000 kbps once the limit is reached. For travelers who need more data without throttling, 4S eSIM offers fixed‑data options; for example, packages of 50GB can be purchased for 5, 7, 15, 30, or 90 days, and 30GB plans are available for 15 or 30 days. These fixed‑data plans allow consumers to enjoy full‑speed data throughout the validity period, which can be more cost‑effective unless one requires very high data usage.

4S eSIM does not offer plans that include a phone number or SMS service for East Asia; the provider offers only data‑only eSIMs in that region. Travelers who need to make voice calls or send text messages can use VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection. However, some destinations in East Asia may limit or block access to certain VoIP services, so it is advisable to confirm the availability of the apps you rely on before purchasing a plan.

4S eSIM provides two plans that include coverage in East Asia: the Asia+ plan, which covers China, Hong Kong, Japan, South Korea, and Taiwan, and the Global plan, which likewise includes the same set of East Asian countries.
