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” in their name actually allow 3 GB of high‑speed data per day and then reduce the speed to 1000 kbps after that daily limit is reached. For travelers who need more data without a daily cap, Simsima offers fixed data plans such as 100 GB for 180 days or 50 GB for 30 days, which can be more cost‑effective unless the user is an extremely heavy data consumer.
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.
