My current plan is MySuperPlan... is it still possible to change the boosters and combos? anyway based on their Terms and Conditions we are only obliged to change plan if we are renewing our contract..
YES, it is possible to change boosters and combos monthly, but if you change your combos this will take effect day after your cut off date, then the booster will activate real time but booster will be charge on top of your plan. // combos is covered by your base plan that can be change monthly then boosters is addons on your base plan.
The terms and conditions that you mentioned is for changing the base plan.
