- Emily (Australia, July 2025): Bought a MobiFone SIM at the airport for $25 (6GB/day). It worked fine in Hanoi and Halong, but she later realized her friend’s GoVnSIM eSIM ($18.50) was cheaper and activated instantly before landing.

- Sophie (France): Bought a Vinaphone SIM in Hanoi’s Old Quarter for $23. Setup was easy, but she had to rely on airport WiFi to book her taxi into town before getting connected.
