ZenSim does not provide a true unlimited data eSIM for Malta. All of its Malta‑specific plans have a defined data cap of 3GB per day; after this threshold is reached the speed is reduced to the plan’s reduced‑speed rate, so the plan is not unlimited in the sense of continuous, high‑speed data.
For travelers who need substantial data, ZenSim offers fixed‑data alternatives that combine a large allowance with a longer validity. For example, the Malta 20GB plan is available for 10 days at a price of $23.00 USD and for 30 days at $24.00 USD, and the Malta 10GB plan offers 10GB for 10 days at $15.00 USD. These fixed‑data plans can be more cost‑effective than trying to extend a daily capped plan, especially for heavy data users.
