how do i transfer my fizz calls and text messages to another number ?

If you have an Android phone, this app may be of use to you; it forwards SMS text messages & calls from one phone to another phone.

If you are looking for a more permanent solution, this may involve making more substantive adjustments to your account.

If you have an iPhone, you can transfer texts and phone calls to another device.

Thanks for the update
