RoameSIM eSIM Data Plans for Asia

RoameSIM does not provide a genuinely unlimited data eSIM for travelers in Asia. The plans labeled “Asia – Unlimited” actually give a fixed allowance of 3 GB each day, after which the connection is throttled to 1000 kbps.

If a user needs more data, RoameSIM offers fixed‑data options. For example, a 100 GB plan is valid for 180 days, while a 50 GB plan is valid for 90 days. Choosing a plan with a set data limit can be more cost‑effective unless the traveller is an extremely heavy data user.

RoameSIM provides eSIM plans for Asia that include a phone number and SMS capabilities. The plans start with 1 GB of data for 7 days priced at $21.00 USD and extend to 20 GB for 365 days priced at $124.60 USD, covering the same period range. Each plan is valid for the stated number of days and can be used in a broad set of Asian countries such as India, Japan, South Korea, Thailand, Vietnam, Indonesia, Singapore and many others listed in the coverage.

All Asia plans include a phone number with dialing code +1, which is not a local Asian code. Calls can be received and made, and SMS can be received and sent because the voice and SMS fields list both inbound and outbound. Since the number uses the +1 code, users should confirm with RoameSIM whether they need a local number for specific purposes such as local rates or unrestricted roaming.
