I paid for the e-SIM in advance. Upon arrival in the country, I activated the e-SIM in my phone settings. Internet was available immediately. It's that simple!

I bought an e-SIM card in Russia. Upon arrival in Vietnam, I activated it without any problems. I used it for the entire 25 days without any issues. I highly recommend it.

I activated my eSIM right at the airport upon arrival in Vietnam. You choose your connection package, including the number of days and the number of gigabytes per day. The cost is much cheaper than buying it at the airport or through other apps. It's very convenient; you'll already have a connection upon arrival. You can pre-order an eSIM and activate it with a code upon arrival. The 5G speed is lightning fast, the coverage in Da Nang is good, and 2 GB per day is generally enough. I highly recommend it!
