The Simo Solis Lite is my top pick because the setup is simple, the app makes it easy to track data/battery/signal, and the connection stayed stable in real testing. What really stood out is how it switches networks to grab the strongest signal—on one test it beat my phone hotspot by a lot, especially on upload.
Pros
+Simple setup with the Solis app and clear status (data, battery, signal)
+Uses 300+ carriers across 140+ countries with no SIM required
+Connects up to 10 devices; handled 3 devices with no speed impact in my test
+Stable connectivity and often faster than phone hotspot (especially upload)
+Compact, durable puck design; showed no wear after 6 months
+Up to 16 hours battery life
Cons
-Takes around 3 minutes to reach full connectivity after switching on
