Ease to install and no issue use, a good choice to travel without physical card but no phone number as some place ordering food require insert phone number.

It works in a lot of countries, the price isn't anything amazing especially depending where you are traveling but it is convenient. I would recommend getting 1gb per day and be prepared that the coverage isn't great.

★★★★★ The setup was very easy, and I was able to use the internet immediately upon arrival. Using sightseeing and restaurant searches, as well as map apps, was very convenient. I had no complaints about the communication environment during my trip and am extremely satisfied.

The signal was stable in Guam, and I could make free calls to Guam. I called the owner of the EZ car rental company, and the call quality was excellent. The owner even called me back. For any questions, I could add their customer service line for immediate response.
