Yes, you can. During the setup you will be asked whether you would like a subscription with a completely new number, or if you'd like to keep your existing number.
Important: If you want to keep your existing number, please to not cancel your existing subscription. Otherwise your current number will be lost and cannot be reactivated. We will handle the cancel of your number and setup the switch to digitec connect together with your old provider.
You also have the option to test out digitec connect for a month with a new phone number and then switch over to your old number.
