Reviews: Guam 5G eSIM | ChatGPT | 1–30 Days | Instant QR

Guest User2025-11-18

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.

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.

During my trip, I visited three countries, and the SIM card switched seamlessly everywhere, working at maximum speed. I highly recommend it and will definitely use it again!
