CDMA/TDMA models[edit]
Using CDMA and TDMA StarTACs in recent times has become increasingly difficult and now can no longer be done because AT&T shut down their 2G network in 2017.[21] rendering TDMA models obsolete. Carriers such as Verizon still operate a compatible CDMA network. However, they will no longer activate CDMA StarTACs on their network as they are not E911 compliant. The FCC has made this a legally required feature for cellular phones. Verizon also requires that handsets on their network support HD Voice and VoLTE.
Users who wished to continue to use CMDA StarTACs following the introduction of E911 were able to do so for some time by activating them with a MVNO operating on Verizon's network such as PagePlus or Tello. MVNOs often didn't perform the proper due diligence to ensure a handset was compliant and allowed these handsets to be activated onto a new plan. This has since changed and activating a CDMA model is no longer possible.
With CMDA and TDMA models no longer working, this has made the aforementioned 7000g and 8000g models even more sought after by collectors as these can still be used with carriers that still support 2G such as T-Mobile.
