I have ordered the new 4G LTE Network Extender, and am currently using with nice success the 3G Extender. When it arrives, and after first disconnecting my old 3G Extender, do I have to call Verizon to have them deactivate my old 3G Extender on their end , or will the system automatically recognize the new 4G LTE Extender when I go through the ramp up process . I have been using an IPhone 7, and am familiar with setting the phone properly...my only question was with the new 4G LTE Extender ...I just was trying to avoid having to call Verizon.......thanks....
