The Pixel 10a brings a welcome connectivity upgrade over Pixel 9a

Google has just launched the Pixel 10a, and it’s basically the same phone as the Pixel 9a. In fact, both phones use the Tensor G4 processor. However, the Pixel maker has now confirmed to us that the new phone has a significant connectivity upgrade.

This is why the Pixel 10a now supports Satellite SOS functionality, allowing you to get emergency assistance in areas without cellular or Wi-Fi coverage.
