When setting up text notifications, users will select either AT&T or Verizon Wireless for Straight Talk Wireless, depending if the phone uses a sim card or not.
  • If the Straight Talk Wireless phone uses a sim card and is a GSM phone, you will choose the AT&T carrier.
  • If the Straight Talk Wireless phone does not take a sim card and is CDMA, it will use Verizon as the carrier in our system.
