Would I please get a QR code Esim Activation
If you are postpaid and an existing Verizon customer, login to My Verizon and go to the section for managing your devices, then pick activate or switch device.
If you are prepaid and an existing Verizon customer, unfortunately the activate/switch device thing doesn't work for some reason. I've seen it reported that you have to go to a store and the employees have to do it. Or you could try contacting Prepaid CS at 888-294-6804 using a different phone (not your old one or the new one) and see if someone can manually push through the device swap over the phone.
If you are new to Verizon and this is your first device with Verizon, then you must either port your phone number to Verizon, or get a phone number with them before your device can be activated.
