How to activate your Gazelle Certified device
Activating a used device may require more than placing your old sim card in your new device. In most cases, you’ll need to go through your carrier’s online “Bring Your Own Device” or “BYOD” page, or you’ll need to visit your carrier’s physical store. Below is a list of links to the major carrier BYOD pages.
While most SIM cards will work with your new device, carriers will recommend that you get a new SIM card when upgrading your phone for best performance. Most Sprint devices will require a new SIM card in order to be activated. Contact your carrier for specifics on acquiring a new SIM card.
