UPDATE: With the new Digi PhoneFreedom 365, you are now allowed to change phones while withing your contract as long as you meet certain conditions after your 17th or 19th month with the phone plan. You can find out more about the PhoneFreedom 365 plan here.
If you'd like, you can also check out the phones available under the plan here
If you'd like to purchase the new iPhone 7 but are still within a contract, you may or may not be incurred a penalty for switching plans.
If your contract's remaining tenure is 2 months or less, you may walk in, or go through our online store (Click on "Keep existing number") to upgrade and change plan with a penalty waiver.
However, if your remaining contract with us is longer than 2 months, you will need to pay the penalty.
