RoameSIM eSIM Data Plans for Southeast Asia

RoameSIM’s “Unlimited” plans for Southeast Asia give users 3 GB of high‑speed data per day for the duration of the plan, after which the speed is reduced to 1000 kbps. Because the data allowance is capped, these are not true unlimited‑data plans.

Instead, users who need larger data budgets can choose RoameSIM’s fixed‑data options such as the 100 GB plan valid for 180 days or the 50 GB plan valid for 90 days, both covering the same countries in Southeast Asia. If a traveler is a very heavy data consumer, a fixed‑data plan may better suit their needs.

Yes, RoameSIM sells eSIM plans that include a phone number and SMS capability for Southeast Asia. The plans range in price from $21.00 USD for a 1 GB data plan valid for 7 days to $124.60 USD for a 20 GB plan valid for 365 days. Each plan provides a phone number with the dialing code +1, meaning the number originates outside Southeast Asia. Calls and SMS can be sent and received on these numbers, and voice service is available both inbound and outbound. The plans also cover nine Southeast Asian countries—Brunei, Indonesia, Laos, Malaysia, Philippines, Singapore, Thailand, Timor‑Leste, and Vietnam—along with 156 additional global destinations. Users who need specific functionality are encouraged to confirm details directly with RoameSIM.

RoameSIM offers several eSIM packages that cover multiple Southeast Asian countries. The various Discover Global plans – including the standard release, the version listed with 10 SMS and the one without additional features – all provide connectivity in Brunei, Indonesia, Cambodia, Laos, Malaysia, Philippines, Singapore, Thailand, Vietnam and Timor‑Leste, while the Asia plan delivers coverage in Indonesia, Cambodia, Laos, Malaysia, Philippines, Singapore, Thailand and Vietnam.
