I really have 2 questions that are related.
I have a friend who wants to use an existing sim and Verizon service on a new unlocked iPhone 6se he bought from Amazon.
Will Verizon allow this phone on the network or must they re-lock it somehow?
If it must be locked to participate, how do I do that?
You will need to verify the device is compatible with the Verizon Wireless network. You can enter the IMEI number here to find out. Bring Your Own Phone or Device - BYOD | Verizon Wireless
I'm most definitely NOT a VZW employee. If a post answered your question, please mark it as the answer.
