Simsima for East Asia FAQ
Does Simsima offer unlimited data eSIM for East Asia?
Simsima does not provide any plan that offers unlimited high‑speed data for East Asia. The plans listed as “Unlimited – 7 days, ” “Unlimited – 10 days, ” and “Unlimited – 30 days” give 3 GB of data per day; once the daily limit is reached the speed is throttled to 1000 kbps, so the data is not truly unlimited.
Travelers who need a larger amount of high‑speed data can choose from fixed‑data plans instead. For example, the 100 GB plan is valid for 180 days, and the 50 GB plan is valid for 90 days, both covering the same East Asian countries. These larger‑data plans may offer a more cost‑effective way to stay connected than the short‑term “Unlimited” options, especially for heavy data users.
Does Simsima offer East Asia eSIM with phone number and SMS?
Simsima does not provide East Asia eSIM plans that include a phone number or SMS capability. The provider offers only data‑only eSIMs for the region. Travelers can still use popular VoIP applications such as WhatsApp, Telegram, and iMessage over the data connection for voice and messaging without requiring a traditional phone number or SMS service.
What countries are covered by Simsima's eSIM plans in East Asia?
Simsima’s eSIM offerings for East Asia come in two distinct plans: the first plan covers China, Hong Kong, Japan, South Korea, Macau, and Taiwan, while the second plan adds Mongolia to that same group of countries.
