I use it for navigation so I don't get lost. I can't say it's bad in that respect, but I can't say it's too good either, okay? (Mom sighs)

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.

Good afternoon everyone. I bought my first e-SIM card for 7 days in Uzbekistan, 20GB with extra storage, for 1,200 rubles and some change. I read customer reviews before buying. In the end, I only used about 4GB of the 20GB. It's a great deal, except that when we arrived in Samarkand, we connected to Wi-Fi at the airport, but they didn't enable roaming, so we couldn't connect. I was a bit disappointed. But, when we arrived at the hotel, we rebooted our phone and connected to the hotel Wi-Fi, and everything worked out! The internet worked well, though it would occasionally lag a bit, but it quickly recovered. We also used Wi-Fi.

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.

The speed was fine, and the setup was easy. Most hotels have Wi-Fi, so 1GB per day is usually sufficient. If you'll be traveling for long periods, it's a good idea to buy an unlimited data SIM.
