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.★

My parents bought me an eSIM card, sent me installation instructions, I followed the link, installed it, and when I got home, I chose the eSIM card. Everything works fine.★

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.
