Simsima for Southeast Asia FAQ
Does Simsima offer unlimited data eSIM for Southeast Asia?
Simsima does not offer a truly unlimited data eSIM for Southeast Asia.
The plans that use the “Unlimited” name provide 3GB of high‑speed data per day; after a 3GB daily threshold all traffic is slowed to 1000kbps, so the amount of usable high‑speed data is still limited.
Travelers who need large data allowances can choose from Simsima’s fixed‑data plans, such as the 100 GB 180‑day plan or the 50 GB 30‑day plan, both of which are available for 5G coverage across Indonesia, Cambodia, Laos, Malaysia, Philippines, Singapore, Thailand, Vietnam and other nearby countries. These fixed plans give a larger total data budget and can be more cost‑effective for heavy users than the limited‑daily “Unlimited” options.
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.
