The signal is unstable. After watching videos for a while each day, the signal becomes extremely slow, and even mobile payment functions become unusable.

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.

The internet was incredibly fast and the signal was consistent. It was easy to use. Throughout the trip, our group used both eSIMs and roaming, and our internet was the fastest and most stable. We used GPS constantly for 9 days and were still able to use TikTok, Instagram, ChatGPT, and Gemini the whole time.
