Update your cell tower roaming list

This includes all cell phones, smartphones and wireless aircards.

Keep your phone on the Verizon Wireless network and/or digital service whenever possible.  There is no charge for this update and it should be done once a month for longer batter life, fewer dropped or blocked calls, and clear connections in more places.

  • Power on your Verizon Wireless phone
  • Dial *228 from your home digital coverage area, followed by the SEND key
  • When prompted, press option #2 to update your phone's roaming capabilities
