Jetpac does not provide a truly unlimited high‑speed eSIM for Vietnam. Their plans titled “Unlimited 7 days” and “Unlimited 10 days” include a 3GB/day allowance and, once that limit is reached, the speed drops to 1024kbps. The name “Unlimited” in these plans refers only to the length of validity, not to an uncapped data allowance.
If a traveler needs more data, Jetpac offers fixed‑data options that can be more cost effective. For example, a 40GB plan for 30 days is priced at $39.99 USD and a 50GB plan for 365 days costs $249.00 USD. These plans deliver full‐speed data up to the stated cap and do not throttle speed until the cap is exceeded.
