In December 2009, Sprint began advertising "4G" service in selected cities in the United States, despite average download speeds of only 3–6 Mbit/s with peak speeds of 10 Mbit/s (not available in all markets).
Detsembris 2009 hakkas Sprint 4G teenust reklaamima valitud linnades USA-s, kuigi keskmine allalaadmimiskiirus oli ainult 3–6 Mbit/s ja maksimaalne 10 Mbit/s.
