Simsima for Southeast Asia FAQ
Does Simsima offer unlimited data eSIM for Southeast Asia?
Simsima does not provide a truly unlimited data eSIM for Southeast Asia. The plans that carry the name “Unlimited” actually give 3GB of high‑speed data each day and then reduce the speed to 1000kbps after that daily limit is reached, so they are not unlimited in the sense of offering unrestricted data.
Travelers who need a larger, fixed amount of high‑speed data can choose from Simsima’s fixed data plans. For example, a 100GB plan is valid for 180 days, and 50GB plans are available for 7, 15, 30, or 90 days. These fixed data plans provide a set amount of data without a daily cap and can be more cost‑effective for most users unless they require very heavy data usage.
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.
What countries are covered by Simsima's eSIM plans in Southeast Asia?
Simsima offers two eSIM plans that cover Southeast Asia. The first plan includes Brunei, Indonesia, Cambodia, Laos, Malaysia, Philippines, Singapore, Thailand, Vietnam and Timor‑Leste, while the second plan covers the same eight countries with the addition of Brunei and Timor‑Leste. Both plans provide coverage solely within the Southeast Asian region.
