There were very rare network drops and loading times were long, but after switching to flight mode and back, everything immediately returned to normal.

Before buying a local SIM card, I purchased this service. Overall, everything installed and worked without any issues. It was more of a problem with the location we were in (Phu Quoc Island)—the internet was quite slow, even on 5G.

Perfect for people coming to China. Easy to use, convenient, connects to the internet and works fine, not too slow.
Reviews: Vietnam MobiFone VNSKY Local 4G/5G eSIM | Daily 9GB | Local Phone Number | 3-30 Days | Activation Requires Advance Reservation | Calendar-Day Billing | QR code

I had been using a non-eSIM compatible phone for a long time, but I switched to a compatible one and used an eSIM for the first time. All I had to do was scan the QR code, and it was activated as soon as I arrived at my destination! It was super cheap and had a lot of data, so I was able to watch about two movies while traveling without any problems!
