I can confirm that you are completely right about Vietnam mobile networks. I could only reliably work after getting a real viettel sim. Even viettel branded stores sell some bootleg sim to tourists that work terribly.
replyThe problem with eSIM is that usually there is no way to judge the quality until you buy one, so people sort by price and choose the cheapest. If your solution offers the best network in the country then I’m interested, because even at x2 or x3 price it doesn’t matter much compared to the other expenses when traveling.
Not sure how you can convince customers outside the hn bubble.
And it's not just Vietnam. It's the same problem thoughout the world. Let me take an example like Saudi Arabia. Airalo connects to Zain and my service connects to STC. There are many such examples.
replyYou are right people do go for the easy thing as there's too much decisions to make. I wonder how I can make it even more explicit on my website than it is now.
Please do try my service and leave a review on Trustpilot. I have a few reviews today but far more people have used my service and have been happy with it.
