The only way is to pay off the device plan and switch the number to a sim only or PAYG tariff.

When you return and cancel an upgrade under the change of mind policy you should be reverted to your original tariff, if it's still available, or at least another similar phone tariff, which would enable you to use your SIM in a phone again.
