Everything works great, the only thing is that you have to turn off the main SIM card for everything to work properly.★

Easy to install. Convenient to use. Good signal. Works well even in many places. There is a link to check how much you have used. Recommended. No need to put in a SIM card, it's a hassle.★

I used it in Hanoi, Da Nang, and Sapa. It was very convenient because it connected at high speeds anywhere and also allowed tethering. I was worried about setting it up because it was an eSIM, but it was very easy and connected quickly, which was great.
