Sprint uses the 1900 MHz band for both voice and data service. For this reason, you will want to use a
PCS or Dual Band amplifier and antenna. It should also be noted that Sprint has many active roaming contracts, in which case voice may sometimes be carried on the 800 MHz band. If you are in an area where you are likely to roam, you will want to use Dual Band equipment. Otherwise, a PCS amplifier will be ideal.
