Firsty does not offer an unlimited data eSIM for Vietnam. Their current packages provide a fixed allowance of 8 GB per day, available in day‑by‑day increments ranging from 1 day up to 10 days, each with a reduced speed of 512 kbps. For instance, an 8 GB/day plan lasting 3 days costs $22.98 USD, and an 8 GB/day plan lasting 10 days costs $243.74 USD.
