eSIMzio for Southeast Asia FAQ
Does eSIMzio offer unlimited data eSIM for Southeast Asia?
eSIMzio does not provide a truly unlimited data eSIM for Southeast Asia. The plans branded “Asia Unlimited” deliver a 3 GB per day allowance that drops to a reduced speed of 1 Mbps after the daily limit is reached, so the data is not unlimited in the sense of no cap.
Instead, eSIMzio offers fixed data plans that can give travellers large amounts of data. For example, the Asia 50 GB plan is valid for 90 days and the Asia 100 GB plan is valid for 180 days. The Global 60 GB plan, valid for 125 days, also covers Southeast Asian destinations. These fixed data plans can be more cost‑effective for most users unless extremely heavy data use is required.
Does eSIMzio offer Southeast Asia eSIM with phone number and SMS?
eSIMzio does not provide Southeast Asia eSIM plans that include a phone number or SMS capability; the provider only offers data‑only eSIMs for that region. Travelers who need to make calls or send messages can use popular VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection. However, some destinations may block or restrict access to specific apps or VoIP services, so it is advisable to verify that the apps you rely on are available in the countries you plan to visit before purchasing a plan.
What countries are covered by eSIMzio's eSIM plans in Southeast Asia?
eSIMzio offers two distinct plans that cover Southeast Asia: a Global plan and an Asia plan. Both plans provide coverage for Brunei, Indonesia, Cambodia, Laos, Malaysia, Philippines, Singapore, Thailand, Timor‑Leste, and Vietnam. While the plans also include additional regions, the Southeast Asian countries listed above are the ones covered by each plan.
