How to buy and activate a SIM card or eSIM in Nha Trang, Vietnam?

TL;DR
The easiest option is to buy an eSIM in advance through an app (Airalo, Saily) and activate it before your flight, or get a physical Viettel/Mobifone SIM at Cam Ranh airport or a phone shop in the city for about 150,000–250,000 VND with a monthly data package.

Before flying to Nha Trang, many travelers ask how to properly set up an eSIM — it's recommended to buy and activate it in advance through a dedicated app so internet works right after landing.

If buying a physical SIM after arriving in Nha Trang, you first activate it with the vendor (passport is usually required), and then the question is how to keep using Telegram if your account is tied to a different number — usually it's enough to just keep your old SIM as a backup for receiving login codes, without changing the number in Telegram.

When planning a trip to Nha Trang for mid-month (around the 10th-12th), travelers often sort out SIM/eSIM details in advance so they don't have to deal with it after arrival.
