Simsima for East Asia FAQ
Does Simsima offer unlimited data eSIM for East Asia?
Simsima does not provide a truly unlimited data eSIM for East Asia; the plans that carry the word “Unlimited” actually allow 3GB of high‑speed data per day, after which the speed falls to 1000kbps.
Travelers who need larger high‑speed data allocations can choose fixed‑data plans such as the 100 GB plan valid for 180 days or the 50 GB plan valid for 90 days. These provide higher capacities at a fixed price and may be more cost‑effective for users who exceed the 3GB/day limit of the “Unlimited” options.
Does Simsima offer East Asia eSIM with phone number and SMS?
Simsima does not provide eSIM plans for East Asia that include a local phone number or SMS capability. Only data‑only plans are available for travelers to the region. Travelers who need voice or messaging can use popular VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection, but some destinations in East Asia may block or restrict these services, so it is advisable to confirm that the apps a traveler relies on are accessible before purchasing.
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.
