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.

It comes with an installation guide, works well, and has clear sound. It's suitable for international travel. 1 GB per day is sufficient for sightseeing.

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

Everything worked great. There were connection issues at first, but support quickly helped resolve the issue. The internet worked even on the road and on the mountain. Thank you!
