Simsima for East Asia FAQ
Does Simsima offer unlimited data eSIM for East Asia?
Simsima does not provide a truly unlimited high‑speed data eSIM for East Asia. The plans that carry “Unlimited” in their names offer 3GB of 5G data per day; after that daily quota is reached the speed is throttled to 1 Mbps. Once the daily limit is exhausted, the remaining data in the plan continues to be usable, but at the reduced speed.
If a traveler needs a larger data allowance, Simsima sells fixed data plans. For example, the 50 GB plan can be purchased for 30 days at $54.38 USD, or the 100 GB plan is available for 180 days for $178.48 USD. These fixed data plans allow the full amount of data to be used at 5G speed until the validity period expires, making them more cost‑effective for most users than the “Unlimited” plans with daily throttling.
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.
