Although the eSIM I purchased from ETravelSim was cheap, it was provided by Vietnamobile, and the speed was slow and the coverage wasn't very good either (especially in Nha Trang). I also didn't know how to check the remaining data because it was not clear in the instruction provided.
It might be okay if you are staying in HCMC or Hanoi, but not ideal if you are traveling other smaller cities.
The eSIM I got from GIGAGO, which connects to Vinaphone, was much better.
