MobileSIM eSIM Data Plans for Malaysia

MobileSIM does not provide a true unlimited data eSIM for travelers in Malaysia. All of its “Malaysia Unlimited data for X days” plans give a fixed allowance of 3 GB per day and then throttle speed to 1000 kbps once the limit is reached. Therefore, while the plan names contain the word unlimited, the data service is capped and reduced after the daily quota is used.

For users who need higher usage or want to avoid reduced speed, MobileSIM offers fixed data packages. For example, the Malaysia 20 GB for 30 days plan gives a large, unthrottled allowance at a lower daily cost, and the Asia 100 GB for 180 days plan provides an even larger data bundle that is also available across Malaysia and 17 neighbouring countries. These fixed data options can be more cost‑effective for heavy data consumers or for those who prefer consistent high‑speed connectivity.

MobileSIM does not provide an eSIM plan for Malaysia that includes a local phone number or the ability to send or receive SMS messages.

Only data‑only eSIMs are sold by MobileSIM for travelers in Malaysia. Travelers who need voice or messaging can rely on internet‑based services such as WhatsApp, Telegram or iMessage, which work over the data connection without requiring a traditional phone number or SMS capability.

MobileSIM’s catalogue for Malaysia lists 12 single‑country plans and 14 multi‑country plans. The single‑country options range from about $4.50 to $185 and offer data caps from 1 GB up to roughly 100 GB. The multi‑country plans cover the same price and data spectrum. Within the full set of plans, six are based on daily data caps while 20 are fixed‑data‑cap plans, giving travellers a variety of ways to choose the right data bundle for their stay.
