Using an eSIM in Saipan was so convenient! I bought a data plan in the app within minutes before departure, and the moment the plane landed, I was instantly connected to the 5G network. The internet speed was super fast, and navigation, uploading videos, and checking travel guides were all smooth sailing. The price was also more affordable than buying a physical SIM card locally. No need to change SIM cards or find a SIM card ejector tool; everything is done with just your phone—effortless and smart. I highly recommend it to all independent travelers!

The speed was fine and the setup was easy. Most hotels have Wi-Fi, so 1G per day is usually fine. If you're traveling for long periods of time, it's a good idea to buy an unlimited SIM card.

The connection is fantastic! I got a 20GB plan for 15 days for a trip from Istanbul, Turkey, to Cairo, Egypt, and Hurghada. The connection is great, I'm sharing it with a friend, and it's enough to even watch movies! I recommend it to everyone. 👍🏻

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.
