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 products titled “Unlimited – 7 days, ” “Unlimited – 10 days, ” and “Unlimited – 30 days” give users 3GB of 5G data each day; after the 3GB limit is reached, the connection is throttled to 1000 kbps.
Travelers who need more data can select from Simsima’s fixed‑data plans that cover the same Southeast Asian countries. Two examples are the 100GB plan for 180 days priced at $84.00 USD and the 50GB plan for 90 days priced at $56.83 USD; both provide high‑speed 5G data without a daily limit. These options may be more cost‑effective for users who consume data heavily.
Does Simsima offer Southeast Asia eSIM with phone number and SMS?
Simsima does not provide eSIM plans in Southeast Asia that include a phone number or SMS capability; all available plans are data‑only. Travelers who need messaging or voice communication over the data connection can use VoIP apps such as WhatsApp, Telegram, and iMessage. However, some destinations may restrict access to these services, so it is advisable to verify that the apps you intend to use are available in the specific country before purchasing a Simsima eSIM.
