Cellular models can handle calls, messages, and standalone phone-style use, though the evidence suggests good practicality rather than class-leading coverage.
LTE is the headline upgrade and usually works well for calls, texts, LiveTrack, and phone-free use, but not every reviewer found it fully dependable.
