Can you get a SIM card with calling (not just mobile data) in Nha Trang, Vietnam?

TL;DR
Most SIM cards sold to foreigners in Nha Trang are data-only (around 600 rub / ~$7 for 20 days), with calls made via messenger apps. A full voice-calling SIM is largely unavailable to foreigners by law unless the carrier supports Wi-Fi calling.
What the community said
After days of searching (eSIM, carrier calling plans), it turned out that under Vietnamese telecom law, foreigners can't get voice service if the carrier doesn't support Wi-Fi calling — leaving no real workaround.

Every option tried — from eSIM to regular carrier calling plans — either didn't actually work or was too expensive to be practical.

If your local SIM's data runs out a couple of days before it expires, look for a trusted local reseller to top it up instead of buying a brand-new SIM.

A tourist data-only SIM (no calling) cost around 600 rub (~$7) for 20 days — enough data for Google Maps, taxi apps, and all messenger apps, with calls received via messenger apps instead.
