As you may know, Verizon used to use CDMA protocol that tied your service to the device you’ll be using. While LTE & 5G no longer follow these protocols, you still need to authenticate your phone with the SIM to make it usable. The rule also applies to the MVNOs using its (Verizon) towers. So, to activate your wireless Entouch phone, you’ll have to power it on and wait for the initial setup to complete. Then call the customer care number 866-488-8719 to complete the process. The representative will ask for the ICCID of your lifeline SIM, thereby having it at hand.
