Opt for constant connectivity

With optional LTE connectivity in select markets, you can access the internet wherever the day takes you—even without a WiFi signal. Or opt for Intel WiFi 6, with 75% lower latency than standard AC WiFi. Stream smoother and browse with no delays—you’ll connect with unprecedented speed.
