This brief article explains the function of a SIM card and how to perform a SIM swap:
An important concept to understand that can be very helpful is that a phone number is associated with a SIM card and not a phone/device. When this is understood, it answers the question to the following scenario:
An individual has an active Gabb Phone(Z2)/phone number and just received a new Gabb Phone Plus. How would this individual transfer the active phone number from the Gabb Phone (Z2) to the new Gabb Phone Plus?
Answer 1: This individual could simply insert the active SIM card from the Gabb Phone (Z2) into the Gabb Phone Plus. The Gabb Phone Plus now has the phone number. This is called a physical SIM transfer.
Why? Because the active phone number was housed with the SIM card and not the device. This option is not available for Gabb Watches because the SIM card is embedded in the device and options two must be used:
Answer 2: Perform a SIM swap.
A SIM swap assigns a phone number to a different (many times new) SIM card. This is done inside your account at gabbwireless.com/account
1. Login to your account gabbwireless.com/account
2. Select "View Details" under the device that needs a SIM swap
3. Select "Swap SIM" (pictured below)
4. Enter the 20 digit ICC number found on your new SIM Card
5. Select "Continue" and follow the rest of the prompts
After rebooting your device, your phone number should now be transferred and associated with a new SIM card.
