Can I activate a Vietnam travel eSIM before arrival, or do I need to wait until I land in Vietnam?

TL;DR
Travelers report that some Vietnam travel eSIMs may not activate while still in Russia. The safer option is to activate after landing using airport Wi‑Fi; if your phone does not support eSIM, buy a local physical SIM on arrival.

A recent traveler reported that the eSIM would not activate in Moscow, but it worked normally after landing in Vietnam when connected to airport Wi‑Fi.

If your phone does not support eSIM, the practical workaround is to skip pre-trip setup and buy a local physical SIM card after arriving in Vietnam.

Based on traveler reports, you should not rely on a Vietnam travel eSIM working while still in Russia: even if the package still has days left, it is safer to expect it to work only once you are in Vietnam.
