Sunrise smartphone upgrade – How long will my contract last?
You sign up for a normal device plan with a term of 24 months. If you use the Sunrise smartphone upgrade option after 12 months and trade in your iPhone, the existing device plan ends and you sign up for a new 24-month device plan with your new iPhone. After another 12 months, you can again switch to the latest iPhone model. If you do not use the option, the device belongs to you after you have paid the 24 monthly installments.
