Which local networks does the Vietnam eSIM connect to? (Viettel / Mobifone?)

 To give you the best coverage in this long, thin country, our eSIM connects to the top-tier providers, typically Viettel or Vinaphone. Viettel is widely considered the best network (like the military's network) with the most extensive coverage, especially in rural and mountainous areas, ensuring you stay connected where other networks fail.
