The TravelWifi Sapphire 3 is the one I’d point to for frequent international travelers because it downloads regional eSIMs from the cloud and works across 130+ countries. Once connected, it handled an international Zoom call while sharing video with no issues, and it felt better than my phone hotspot mode.
Pros
+Cloud-based eSIM downloads; no physical SIM needed
+Works in 130+ countries and connects to strong 4G LTE signal
+Includes 4GB free global data and supports prepaid/pay-as-you-go plans
+Fast reconnect once paired (about 10 seconds)
+Stable enough for Zoom and simultaneous video sharing
+Strong real-world battery: over 11 hours of constant use with two devices
Cons
-No rollover data plans (made it less ideal for shorter trips)
-Initial setup required a reboot to connect with my laptop
