Simsima for Southeast Asia FAQ
Does Simsima offer unlimited data eSIM for Southeast Asia?
Simsima does not provide a truly unlimited high‑speed data eSIM for Southeast Asia. The plans titled “Unlimited” give a fixed daily allowance of 3 GB; once that limit is reached the speed is throttled to 1000 kbps, so the data is not unlimited in the usual sense.
Travelers who need larger data volumes can choose from Simsima’s fixed‑data plans, such as the 100 GB plan valid for 180 days or the 50 GB plan valid for 90 days, both of which offer full‑speed data within the allocated amount. These larger‑allowance options can be more cost‑effective for users who consume significant data during their stay in Southeast Asia.
Does Simsima offer Southeast Asia eSIM with phone number and SMS?
Simsima does not offer any Southeast Asia eSIM plans that include a local phone number or SMS functionality; only data‑only plans are available from the provider. Travelers who need to make calls or send messages can still use popular VoIP applications such as WhatsApp, Telegram, and iMessage, which operate over the data connection.
What countries are covered by Simsima's eSIM plans in Southeast Asia?
The two unnamed plans offered by Simsima cover the following Southeast Asian countries: the first plan includes Indonesia, Cambodia, Laos, Malaysia, Philippines, Singapore, Thailand, and Vietnam; the second plan covers those same eight nations plus Brunei and Timor‑Leste, providing the same core ASEAN coverage with the additional two countries. These are the only Southeast Asian destinations included in Simsima’s eSIM offerings.
