Yes, ASIMGO offers several unlimited‑data eSIM plans for Vietnam. The plans are available in 1‑day, 3‑day, 5‑day, 7‑day, 10‑day, 15‑day, 20‑day, 30‑day and even 15‑day variants, with prices ranging from $1.98 for a 1‑day plan up to $108.19 for a 30‑day plan. All these plans have a data cap marked as Unlimited; data usage is subject to a Fair Usage Policy, meaning speeds may be throttled after heavy use, with a maximum speed of 10000kbps for the Vietnam‑only plans and 5000kbps for the regional packages. Travelers should confirm with ASIMGO if FUP applies and what typical data availability at normal speed is expected.
