After paying according to the instructions, I installed the eSIM card at home, and it activated immediately upon arrival. The speed was sufficient for everything. We purchased 2GB per day packages.

Great coverage even on the island! Used this eSIM during my trip to Phú Quốc and it worked flawlessly. Coverage was strong everywhere—from Dương Đông town to the southern beaches and even up north near the safari. Installation was easy and I had service immediately after landing. Highly recommend!

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.

Perfect for people coming to China. Easy to use, convenient, connects to the internet and works fine, not too slow.
