How much does a tourist eSIM or SIM card cost in Nha Trang for 7 to 15 days of mobile data?

A no-number eSIM for 15 days cost 1,000 RUB. It included 1 GB per day at full speed plus 99 GB throttled to 10 Mbps, with the allowance resetting daily.

A 10-day eSIM with 3 GB per day was purchased for 750 RUB. The traveler reported being connected before the plane had landed.

Another traveler bought a physical SIM for 150,000 VND, with the seller claiming unlimited data for a month. Only used it for one day so far, so feedback is preliminary.

A physical SIM can be purchased directly at a Viettel store: one traveler paid 650,000 VND for 30 days, which she found about three times pricier than a comparable eSIM.

A 15-day eSIM plan with 7 GB per day is available in the market. Travelers mentioned this as a prepaid package ready for activation, suggesting that two-week tourist data bundles are common.

One traveler paid 400 RUB for a 14-day data-only eSIM. According to their experience, it started working immediately after landing, even before leaving the plane.

There are also ultra-cheap promotional eSIM deals: one traveler mentioned a voucher valid for activation until August 3 that cost just 1 RUB. This sounds more like a one-off promotion than a normal market rate.

Travelers also reported eSIM pricing of around 250 RUB for 15 days. This was considered a normal and realistic rate for Vietnam.

For local physical SIM options, travelers mentioned a 7-day package with 50 GB for 190,000 VND. One practical detail: payment was cash only.

One reported eSIM plan included a local phone number and cost about 450 RUB for 15 days, with 9 GB per day. This was one of the pricier options mentioned.

For comparison, another traveler activated a 15-day eSIM for around 260 RUB and considered 450 RUB expensive. That suggests a budget-friendly range often starts around 250–260 RUB.
