My phone is broke and I have another Verizon phone to use but need to port my number to it. How do I do that without talking to a live human over the phone and doing it tonight while the stores are closed?
You don't mention what two devices are? If they both use the same Sim size (micro or nano) not a mismatch then take the same size Sim out of the previous device and put it in the replacement device.
If Sim is different size, you may be able to log into your My Verizon web portal and swap Emeid numbers from the old one to the new.
Or simply wait until the store is open and let them swap the devices.
