Selective Dynamic Group Calling

Selective Dynamic Group Call (SDGC) gives users the ability to create a customized group list on their phone at any time and initiate a PTT call to that group. SDGC PTT calls can be made across Southern Linc fleets or within the same fleet -- just choose the contact and add them to the group.

Most phone models sold by Southern Linc over the last 2 years are SDGC capable, but a special purple SDGC SIM card is required to access the feature on our network. This SIM is available for $15 at any Southern Linc store, Authorized Dealer or at the online store at onlinestore.southernlinc.com.

Using SDGC is easy!

What do I do after I buy the SDGC SIM card?
  • If you purchased your new SIM online, Call the Customer Solution at 1-800-406-0151 and ask a representative to "swap" the SIM card associated with your phone to the new purple SIM. If you are purchasing from a Southern Linc store or Authorized Dealer, they will handle this step for you.
  • Copy the contacts saved on your current SIM card to your new purple SIM. The fastest and easiest method to transfer contacts is by using a SIM copier. A SIM copier can be purchased from the Southern Linc online store or you can visit a Southern Linc store or Authorized Dealer for assistance with this step.
  • Place the new purple SIM card in your phone and power up your phone. You're now ready to create groups and make PTT group calls!
